Answer:

Tommy earned $250 altogether.

Step-by-step explanation:

Let the total earning of Tommy be 'x' dollars.

Given:

Money spent on entertainment = $80

From the circle shown below:

Percent spent on clothes = 19%

Percent spent on food = 25%

Percent spent on other things = 14%

Percent of savings = 10%

Addition of all percents = 100%

⇒ 19% + 25% + 10% + 14% + % Entertainment = 100%

⇒ 68% + % Entertainment = 100%

⇒ % Entertainment = 100% - 68% = 32%

Therefore, as per question:

[tex]32\%\ of\ x=\$80\\\\0.32x=80\\\\x=\frac{80}{0.32}\\\\x=\$250\\[/tex]

Hence, Tommy earned $250 altogether.

The graph of the function [tex]f(x)=-\sqrt{x}[/tex] is the first graph which is attached below.

Step-by-step explanation:

The function is [tex]f(x)=-\sqrt{x}[/tex]

To graph the function, we need to know the domain and range of the function.

The domain is found by substituting the values for x.

Thus, the domain is [tex]x\geq 0[/tex]

The range of the function is determined as [tex]y\leq 0[/tex]. Since, substituting the values of x we get the corresponding y-value which lies in the interval [tex](-\infty, 0][/tex].

A. Jose would be 30 feet east of the mailbox after 5 seconds.

B. A formula that expresses Jose's distance from the mailbox is,

D = 10 + 6t

C. As time increases, his distance from the mailbox increases proportionally.

Given that;

Jose is standing 10 feet east of a mailbox when he begins walking directly east of the mailbox at a constant speed of 6 feet per second.

A. In 5 seconds,

Jose would have travelled a distance equal to his speed multiplied by the time.

Since he is walking directly east, the distance travelled would be;

6 feet/second × 5 seconds = 30 feet.

Therefore, Jose would be 30 feet east of the mailbox after 5 seconds.

B. To express Jose's distance from the mailbox (D) in terms of the number of seconds (t) since he started walking, use the formula:

D = 10 + 6t

The initial distance from the mailbox which is 10 feet is added to the distance he walks 6 feet/second × t seconds to get the total distance.

C. Yes, Jose's distance from the mailbox is proportional to the time elapsed since he started walking away from the mailbox.

This is evident from the formula D = 10 + 6t

Jose is 40 feet from the mailbox after 5 seconds. His distance from the mailbox can be expressed by the formula D=10+6t. His distance from the mailbox is proportional to the time elapsed since he started walking away from the mailbox.

A. Since Jose is moving at a speed of 6 feet per second, after 5 seconds, he would have walked 5*6=30 feet. He initially starts 10 feet east of the mailbox, so his total distance from the mailbox 5 seconds later is 10+30=40 feet.

B. The formula that expresses Jose's distance from the mailbox in terms of the number of seconds t since he started walking is D = 10 + 6t, where D is the distance and t is the time in seconds. In this formula, 10 represents his initial distance from the mailbox, and 6t represents how far he walks.

C. Yes, as Jose walks away from the mailbox, his distance from the mailbox is proportional to the time elapsed since he started walking away from the mailbox. This can be seen from the formula D=10+6t, which is in the form y=mx+b, indicating a linear relationship in which the dependent variable (distance) is proportional to the independent variable (time).

Answer:

maximum height =7.347m

Step-by-step explanation:

maximum height = (U²sin²θ)/2g

where θ = 90° as the ball is thrown straight up.

sin90°=1 , so our formula reduces to;

H= U²/2g

U=12m/s  , g=9.8m/s²

H= 12²/(2*9.8)

H=7.347m

Answer:H=7.339m

Step-by-step explanation:

The formula to find maximum height is :

H= v^2/(2× g)

V means speed=12 m/s

g means acceleration due gravity (constant)= 9.81m/s^2

Apply the formula

H=(12^2)/(2×9.81)

H=144/19.62

H=7.339m

Answer:

The estimated number of deer in this population will be 147.

Step-by-step explanation:

Let we assume

Total number of deer = x

If we presume that this sample ratio is typical for the entire herd

Then,

The ratio of total number of the deer and initially collected, tagged and released deer will be equal to the ratio of later captured 55 deer and 9 tagged deer.

So

[tex]\frac{x}{24}=\frac{55}{9}[/tex]

[tex]x=\frac{55}{9}\times24[/tex]

[tex]x=146.66[/tex]

Hence the estimate number of deer = 147

Answer:19+25+10+14+80 gives you 148

Step-by-step explanation:

Tommy earned approximately $68 altogether.

Given:

- Clothes: 19%

- Food: 25%

- Savings: 10%

- Other: 14%

To find out how much Tommy earned altogether, we need to detemine what percentage of his earnings $80 on entertainment represents.

First, we sum up these percentages to find out what portion of his earnings $80 represents:

Total percentage spent = Clothes + Food + Savings + Other

Total percentage spent = 19% + 25% + 10% + 14%

Total percentage spent = 68%

Now, we need to find out how much $80 represents as a percentage of his total earnings:

Percentage of earnings spent on entertainment = (Amount spent on entertainment / Total percentage spent) * 100%

Percentage of earnings spent on entertainment = (80 / 68) * 100%

Percentage of earnings spent on entertainment ≈ 117.65%

Now, to find out how much Tommy earned altogether, we need to determine the total amount represented by 100%, which is his total earnings. Since $80 represents approximately 117.65% of his earnings:

Total earnings = (Amount spent on entertainment / Percentage of earnings spent on entertainment) * 100%

Total earnings = (80 / 117.65%) * 100%

Total earnings ≈ $68

Therefore, Tommy earned approximately $68 altogether.

There were 20 people in the room, as each person kissed every other person once, resulting in [tex]\( \frac{20 \times 19}{2} = 190 \)[/tex] kisses.

Let's denote n as the number of people in the room. In this scenario, each person kisses every other person once, resulting in a total of [tex]\( \frac{n(n-1)}{2} \)[/tex] kisses.

Given that there were 190 kisses, we can set up the equation:

[tex]\[ \frac{n(n-1)}{2} = 190 \][/tex]

To solve for n, we multiply both sides of the equation by 2 to get rid of the fraction:

[tex]\[ n(n-1) = 380 \][/tex]

Expanding the left side:

[tex]\[ n^2 - n = 380 \][/tex]

Rearranging the equation into a quadratic form:

[tex]\[ n^2 - n - 380 = 0 \][/tex]

Now, we can solve this quadratic equation. One way is by factoring, if possible. If not, we can use the quadratic formula:

[tex]\[ n = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} \][/tex]

where [tex]\( a = 1 \), \( b = -1 \), and \( c = -380 \).[/tex]

Plugging in the values:

[tex]\[ n = \frac{{-(-1) \pm \sqrt{{(-1)^2 - 4(1)(-380)}}}}{{2(1)}} \]\[ n = \frac{{1 \pm \sqrt{{1 + 1520}}}}{2} \]\[ n = \frac{{1 \pm \sqrt{{1521}}}}{2} \]\[ n = \frac{{1 \pm 39}}{{2}} \]\[ n = \frac{{1 + 39}}{{2}} \quad \text{or} \quad n = \frac{{1 - 39}}{{2}} \]\[ n = \frac{{40}}{{2}} \quad \text{or} \quad n = \frac{{-38}}{{2}} \]\[ n = 20 \quad \text{or} \quad n = -19 \][/tex]

Since the number of people cannot be negative, we discard n = -19.

Therefore, there were [tex]\( \boxed{20} \)[/tex] people in the room.

The value of the constants b and c in the given polynomial, p(x) = x² + bx + c are b = 2, and c = -24.

Given a polynomial:

p(x) = x² + bx + c

It is also given that:

[tex]\lim_{x \to 4} \frac{p(x)}{x-4} =10[/tex]

Since the denominator is x - 4 when the limit sets to 4, the denominator will have 0 there.

But, this can't be possible.

So, the expression inside the limit is given below:

[tex]\lim_{x \to 4}\frac{(x+a)(x-4)}{x-4}=10[/tex]

When the limit tends to 10, the expression becomes:

4 + a = 10

a = 6

So, the expression inside the limit becomes:

p(x) = (x + 6)(x - 4)

      = x² + 6x - 4x - 24

      = x² + 2x - 24

So, x² + bx + c = x² + 2x - 24

The constants b and c in the polynomial satisfy the equation 4b + c = 24. There are infinitely many pairs of (b, c) that can satisfy this equation, therefore they are not unique.

In this question, we are dealing with limits and polynomials. We are given that p(x) = x2 + bx + c and lim x→4 [p(x)/(x-4)] = 10.

Substituting p(x) into the equation, we get lim x→4 [(x2 + bx + c) / (x - 4)] = 10.

Using the rule lim x→a [f(x)] = f(a), we find that 42 + 4b + c = 40. This simplifies to 16 + 4b + c = 40, and further to 4b + c = 24.

So, the constants b and c must satisfy this equation. Therefore, they are not unique as there are infinitely many pairs of (b, c) that can satisfy this equation. For example, if b = 5, then c = 4. If b = 6, then c = 0. And so on.

Answer:

y = (x + 7) (x + 6) (x − 3)

Step-by-step explanation:

Using rational root theorem, possible rational roots are:

±1, ±2, ±3, ±6, ±7, ±9, ±14, ±18, ±21, ±42, ±63, ±126

Using trial and error, we find that +3 is one of the roots.

There are 3 ways to continue from here: continue using trial and error to look for other rational roots; use long division to factor; or use grouping.

Using grouping:

y = x³ + 10x² + 3x − 126

y = x³ + 10x² − 39x + 42x − 126

y = x (x² + 10x − 39) + 42 (x − 3)

y = x (x + 13) (x − 3) + 42 (x − 3)

y = (x (x + 13) + 42) (x − 3)

y = (x² + 13x + 42) (x − 3)

Answer:

Option C. 16

Step-by-step explanation:

Number of differents colors = 4

Number of differents sizes = 2

Case 1: 3 notepads of the same size and the same color:

If we have a package with the same size and the same color, the number of possible packages is:

N° packages = 4(colors)*2(sizes) = 8

Case 2: 3 notepads of the same size and different colors:      

In this case, to calculate the number of possible permutations of packages without repetitions we need to use the following equation:    

[tex] C_{n}^[p} = \frac{n!}{p!(n-p)!} [/tex]

where p: is the number of colors for each package = 3, and n: is the total number of colors = 4.

[tex] C_{4}^[3} = \frac{4!}{3!(4-3)!} = \frac{4*3*2*1}{3*2*1} = 4 [/tex]

This number calculated is for one size, if the have two different sizes the number of possible packages is:

N° packages = 4(colors)*2(sizes) = 8    

Therefore, the total number of different possible packages is:

N° packages = case 1 + case 2 = 8 + 8 = 16

So, the correct answer is option C = 16.

Answer:

A) True

Step-by-step explanation:

A basic variable is a variable that corresponds to a pivot column. A variable that does not corresponds to a pivot column is known as a free variable. It is required to row reduce the augmented matrix into echelon form so as to determine which of the variables are free and which of them are basic.

The statement is true. A basic variable in a linear system corresponds to a pivot column in the coefficient matrix. Basic variables have the leading ones in the matrix, while the rest are free variables.

The statement 'A basic variable in a linear system is a variable that corresponds to a pivot column in the coefficient matrix.' is true. In a linear system, the basic variables are indeed those that correspond to the pivot column in the coefficient matrix. For example, if we have a linear system represented by a coefficient matrix, the basic variables would be the variables associated with the columns that have a leading one (also known as the pivot). The rest of the variables are known as free variables.

Consider a matrix with three columns representing three variables: x, y, and z. If x and y have leading ones and z does not, x and y would be the basic variables, whilst z would be a free variable. Therefore, understanding the relationship between the basic variables and the pivot column in a system's coefficient matrix is crucial in solving linear systems.

In Physics, accuracy and precision are terms used to discuss the validity of measurements. Accuracy refers to how close a measured value is to its true value, while precision discusses the consistency or reproducibility of measurements. Good precision can reduce errors but does not necessarily improve accuracy.

In the field of Physics, accuracy and precision are used to discuss the reliability of measurements taken during experiments. Accuracy refers to how closely the measured value of a quantity corresponds to its 'true' value. For example, if we aim to measure a length of 10 meters, an accurate measurement would be as close to 10 meters as possible.

On the other hand, precision represents the degree of similarity, or reproducibility, between repeated measurements. If we measure the same length of 10 meters multiple times and get results like 9.9m, 10.1m, 10.0m, 9.9m, the measurements would be considered precise because they are closely clustered together, even if they are not necessarily 'accurate' (exact 10m).

It's important to understand that better precision does not always ensure better accuracy. The more measurements you make and the better the precision, the smaller the error will be, but accuracy requires measurements to be close to the actual value.

Answer:

a) Decrease

b) New mean = 78.43

c) Decrease                        

Step-by-step explanation:

We are given the following in the question:

Total number of students in class = 28

Average of 27 students = 79

Standard Deviation of 27 students = 6.5

New student's score = 63

a) The new student's score will decrease the average.

b) New mean

[tex]Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}[/tex]

[tex]Mean = \dfrac{\displaystyle\sum x_i}{27} = 79\\\\\sum x_i = 27\times 79 = 2133[/tex]

New mean =

[tex]\text{ New mean} =\dfrac{ \displaystyle\sum x_i +63}{28}\\\\ =\dfrac{2133+63}{28}= \dfrac{2196}{28} = 78.43[/tex]

Thus, the new mean is 78.43

c) Since the new mean decreases, standard deviation for new scores will decrease.

This is because the new value is within the usual values i.e. within two standard deviations of the mean. So, this wont cause a lot of variation as this value will be closer to already available data values. Also number of observations (n) in the denominator is increasing. Based on both these points we can conclude that standard deviation will decrease

Formula for Standard Deviation:

[tex]\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}[/tex]  

where [tex]x_i[/tex] are data points, [tex]\bar{x}[/tex] is the mean and n is the number of observations.

To construct a Pareto chart for the Wagenlucht Ice Cream Company, rank the flavors by preference, calculate relative frequencies, then draw a bar chart accordingly.

The first step in constructing a Pareto chart is to order your categories (in this case, ice cream flavors) from largest to smallest frequency. Therefore, we will rank them as follows: Choco-Nuts (12), Strawberry Cream (4), and Orange Mint (4).

Then, calculate the relative frequencies - the number of people who preferred a particular flavor divided by the total number of people sampled. Choco-Nuts: 12/20 = 0.6, Strawberry Cream: 4/20 = 0.2, Orange Mint: 4/20 = 0.2.

Start a vertical bar chart with the flavors on the horizontal axis. Using the relative frequencies, draw proportional vertical bars for each: Choco-Nuts would be the tallest, then Strawberry Cream and Orange Mint, which are both the same size. This is your Pareto chart.

Answer:

There are 198 children at the circus show.

Step-by-step explanation:

Let the total number of spectators be 'x'.

Given:

Number of men = [tex]\frac{1}{4}[/tex] of the total number

Number of women = [tex]\frac{2}{5}[/tex] of the remaining number.

Also, number of women = 132

Number of men = [tex]\frac{1}{4}\ of\ x=\frac{x}{4}[/tex]

Now, spectators remaining = Total number - Number of men

Spectators remaining = [tex]x-\frac{x}{4}=\frac{4x-x}{4}=\frac{3x}{4}[/tex]

Now, number of women = [tex]\frac{2}{5}\times \frac{3x}{4}=\frac{6x}{20}[/tex]

Now, as per question:

Number of women = 132. Therefore,

[tex]\frac{6x}{20}=132[/tex]

[tex]6x=132\times 20[/tex]

[tex]x=\frac{2640}{6}=440[/tex]

Therefore, the total number of spectators = 440

Also, number of men = [tex]\frac{x}{4}=\frac{440}{4}=110[/tex]

Now, total number of spectators is the sum of the number of men, women and children.

Let the number of children be 'c'.

Total number = Men + Women + Children

[tex]440=110+132+c\\440=242+c\\c=440-242=198[/tex]

Therefore, there are 198 children at the circus show.

Answer:

Cashew 12.5lb

Peanuts 37.5lb

Step-by-step explanation:

Let the number of pounds of cashewnuts and peanuts be c and p respectively.

Firstly, the total mass of the nuts is 50.

This means:

c + p = 50

Now let’s work with the money

4p + 7c = 4.75(50)

From the first equation, let c = 50 - p

Substitute this into the second equation.

4p + 7(50 - p) = 237.5

4p + 350 - 7p = 237.5

3p = 112.5

P = 112.5/3 = 37.5lb

For Cashew c = 50 - p = 50 - 37.5 = 12.5lb

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.

A biconditional form of the statement about a ligament could be: 'An anatomical structure is a ligament if and only if it is a band of tough tissue connecting bones or holding organs in place.' It defines what a ligament is and the conditions under which we can define a structure as a ligament.

The statement, a 'ligament is a band of tough tissue connecting bones or holding organs in place,' can be written in biconditional form as: 'An anatomical structure is a ligament if and only if it is a band of tough tissue connecting bones or holding organs in place.'

This biconditional statement provides a precise definition and condition as to when we can consider a structure as a ligament. Conversely, it also states that if a structure carries out the functions mentioned, it must be a ligament.

Answer:

The youngest brother's age is 21 years.

Step-by-step explanation:

Given:

The ages of 3 brothers are consecutive integers.

If the oldest brothers age is decreased by twice the youngest brother age the result is -19

To find the age of the youngest brother.

Solution:

Let the age of youngest broth be = [tex]x[/tex]  years

The ages are consecutive integers.

So, age of the next older brother will be = [tex](x+1)[/tex] years

The age of the oldest brother will be = [tex](x+2)[/tex] years

The oldest brothers age is decreased by twice the youngest brother age.

The above statement can be represented as:

⇒ [tex](x+2)-2x[/tex]

Simplifying.

⇒ [tex]x-2x+2[/tex]

⇒[tex]-x+2[/tex]

The result for the above expression = -19.

So, we have:

[tex]-x+2=-19[/tex]

Subtracting both sides by 2.

[tex]-x+2-2=-19-2[/tex]

[tex]-x=-21[/tex]

Multiplying both sides by -1.

∴ [tex]x=21[/tex]

Thus, the youngest brother's age is 21 years

Answer:

Step-by-step explanation:

sin = opposite / hypotenuse

sin x = 36 / 45

sin x = 4/5

the least common number for 36 and 45 is 9

36/9=4

45/9=5

Answer:

sin X = 4/5

Step-by-step explanation:

Hey common, I quite simple. When ever you get a question of this magnitude always remember SohCahToa.

SOH = opposite / hypotenuse

CAH = Adjacent / Hypotenuse

TOA = Opposite / Adjacent

From the question:

Sin X = Opposite / Hypotenuse.

(The opposite of angle X is 36°) over (Hypotenuse - the longest side = 45)

sin X = 36/ 45

Divide through by 3

sin X = 12/15

Divide through by 3 Again

Sin X = 4/5

Answer:

The average of 12 and 40 is 26

Step-by-step explanation:

The average of the values 12 and 40

The variable of average is avg

Average of numbers is sum of all number divide by number of numbers.

Expression:-

[tex]\text{Avg}=\dfrac{12+40}{2}[/tex]

Now simplify the average

[tex]\text{Avg}=\dfrac{52}{2}[/tex]

[tex]\text{Avg}=26[/tex]

Hence, the average of 12 and 40 is 26

The average of the values 12 and 40 is calculated by adding the two numbers together and dividing by 2. This computation can be assigned to a variable named 'avg' in a Python programming context.

To compute the average of the values 12 and 40, you sum the two numbers and then divide by the count of numbers. In this case, there are two numbers, so the sum (12 + 40) is divided by 2. Thus, in the programming language Python, you could write this as:

avg = (12 + 40) / 2

Answer:

5

Step-by-step explanation:

Final answer:

The volume of an oblique pyramid with a square base of edge length 2 cm and a vertical height of 3.75 cm is 5 cm³.

Explanation:

To calculate the volume of an oblique pyramid with a square base, you can use the formula for the volume of a regular pyramid since the oblique nature of the pyramid does not affect the calculation of the volume. The volume formula is Volume = (1/3) times base area times height.

Here, the base edge length is 2 centimeters, so the area of the square base (base area) is Area = side times side = 2 cm times 2 cm = 4 cm². The vertical height of the pyramid is given as 3.75 centimeters. Now we can plug these values into the volume formula:

Volume = (1/3) times base area times height
Volume = (1/3) times 4 cm² times 3.75 cm
Volume = (1/3) times 15 cm³
Volume = 5 cm³

Therefore, the volume of the oblique pyramid is 5 cubic centimeters (cm³).
