Answer:

5f+3g=5.70

2f+10g=3.60

Step-by-step explanation:

Cost of 1 piece of fudge =f

Cost of 1 piece of bubble gum =g

If Chase bought 5 pieces of fudge and 3 pieces of bubble gum for a total of $5.70.

Chase's Cost:

For 5 pieces of Fudge, his cost is 5f

For 3 pieces of bubble gum, his cost is 3g

His Total, 5f+3g=$5.70

Sara bought 2 pieces of fudge and 10 pieces of bubble gum for a total of $3.60.

Sara's Cost:

For 2 pieces of fudge, her cost is 2f

For 10 pieces of bubble gum, her cost is 10g

Her Total, 2f+10g=$3.60

The system of equation that could be used to determine the cost of 1 piece of budge and bubblegum is then:

5f+3g=$5.70

2f+10g=$3.60

Answer: the diameter of the can is 2.8 inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

height = 4.5 inches

Volume of can = 454 millilitres

1 cubic inch = 16.387 millilitres

Converting 454 millilitres to cubic inches, it becomes

454/16.387 = 27.7 cubic inches

Therefore

27.7 = 3.14 × r² × 4.5

27.7 = 14.13r²

r² = 27.7/14.13

r² = 1.96

r = √1.96

r = 1.4

Diameter = 2 × radius

Diameter = 2 × 1.4 = 2.8 inches

Answer:

The time the both trains have to travel for making a distance of 1162.5 miles apart  T = 7.75 hour

Step-by-step explanation:

Speed of the first train = 78 [tex]\frac{mi}{h}[/tex]

Speed of the second train = 72 [tex]\frac{mi}{h}[/tex]

Suppose the both trains have to travel for time = T hour

The distance traveled by first train ( [tex]D_{1}[/tex] ) = Speed × time

⇒ [tex]D_{1}[/tex] = 78 × T --------- (1)

The distance traveled by second train ( [tex]D_{2}[/tex] ) = 72 × T --------- (2)

Total distance D = [tex]D_{1}[/tex] + [tex]D_{2}[/tex]

⇒ D = 78 × T + 72 × T

⇒ 1162.5 = 150 T

⇒ T = 7.75 hour

This is the time the both trains have to travel for making a distance of 1162.5 miles apart.

Final answer:

The sample mean (μ) and standard deviation (σ) are calculated using the provided z-scores and corresponding sample values, resulting in a mean of 30 and a standard deviation of 10.

Explanation:

To solve for the sample mean and standard deviation using the given z-scores and sample values, we can employ the formula for calculating a z-score:

z = (X - μ) / σ

where X is the sample value, μ is the mean, and σ is the standard deviation. For X = 45 with a z-score of 1.50, the equation is:

1.50 = (45 - μ) / σ

For X = 40 with a z-score of 1.00, the equation becomes:

1.00 = (40 - μ) / σ

By solving these two equations simultaneously, we can find the values of μ and σ.

From the first equation, we have:

1.50σ = 45 - μ

From the second equation, we have:

1.00σ = 40 - μ

If we multiply the second equation by 1.5, it becomes:

1.50σ = 60 - 1.5μ

We can set the expressions for 1.50σ equal to each other:

45 - μ = 60 - 1.5μ

Solving for μ gives us the sample mean:

μ = 60 - 45 = 15 / (1.5 - 1) = 15 / 0.5 = 30

To find the standard deviation σ, we substitute μ = 30 into one of the original equations:

1.50σ = 45 - 30 = 15

Therefore, σ = 15 / 1.50 = 10

So, the sample mean (μ) is 30 and the sample standard deviation (σ) is 10.

Final answer:

The sample mean (μ) is 30 and the standard deviation (σ) is 10.

Explanation:

The question is asking to find the sample mean and standard deviation based on given z-scores for specific values in a normal distribution.

To find these parameters, we'll use the formula for calculating a z-score:

z = (X - μ) / σ, where z is the z-score, X is the value, μ is the mean, and σ is the standard deviation.

These two equations can be solved simultaneously to find the values of μ and σ.

Steps for solving them are:

Therefore, the sample mean (μ) is 30 and the standard deviation (σ) is 10.

1. Stratified Random Sampling

Step-by-step explanation:

Sampling is a technique of drawing small number of representative units from population.

Stratified Random Sampling is when population is divided into : heterogenous (different) groups, homogeneous (identical) within themselves - known as Strata.

Process of drawing Sample from each such strata group is called Stratified Random Sampling. This sampling makes sample better representative of various groups in population. Eg : Dividing population in strata based on gender , religion etc & then drawing sample from each strata.

Researcher dividing students into - freshman, sophomores & other groups ; then drawing sample from each group is an example of Stratified Sampling. It creates representative sample of each student body in school .

The researcher is practicing stratified random sampling by dividing the students into groups based on their class standing and randomly selecting a sample from each group.

The researcher is practicing stratified random sampling.

In stratified random sampling, the population is divided into homogeneous groups called strata. The researcher then randomly selects a sample from each stratum to create a representative sample of the entire population.

In this case, the researcher divided the students into groups based on their class standing and randomly selected 50 students from each group.

This ensures that the sample includes students from all class standings and accurately represents the entire student body of the Scion School of Business.

Answer:

City @ 2017 = 8,920,800

Suburbs @ 2017 = 1, 897, 200

Step-by-step explanation:

Solution:

- Let p_c be the population in the city ( in a given year ) and p_s is the population in the suburbs ( in a given year ) . The first sentence tell us that populations p_c' and p_s' for next year would be:

                                  0.94*p_c + 0.04*p_s = p_c'

                                  0.06*p_c + 0.96*p_s = p_s'

- Assuming 6% moved while remaining 94% remained settled at the time of migrations.

- The matrix representation is as follows:

                         [tex]\left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right] \left[\begin{array}{c}p_c\\p_s\end{array}\right] = \left[\begin{array}{c}p_c'\\p_s'\end{array}\right][/tex]          

- In the sequence for where x_k denotes population of kth year and x_k+1 denotes population of x_k+1 year. We have:

                         [tex]\left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right] x_k = x_k_+_1[/tex]

- Let x_o be the populations defined given as 10,000,000 and 800,000 respectively for city and suburbs. We will have a population x_1 as a vector for year 2016 as follows:

                          [tex]\left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right] x_o = x_1[/tex]

- To get the population in year 2017 we will multiply the migration matrix to the population vector x_1 in 2016 to obtain x_2.

                          [tex]x_2 = \left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right]\left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right] x_o[/tex]

- Where,

                         [tex]x_o = \left[\begin{array}{c}10,000,000\\800,000\end{array}\right][/tex]

- The population in 2017 x_2 would be:

                         [tex]x_2 = \left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right]\left[\begin{array}{cc}0.94&0.04\\0.06&0.96\end{array}\right] \left[\begin{array}{c}10,000,000\\800,000\end{array}\right] \\\\\\x_2 = \left[\begin{array}{c}8,920,800\\1,879,200\end{array}\right][/tex]

The estimated populations in 2017 are approximately 9,792,000 for the city and 807,360 for the suburbs

To set up the difference equation for this situation, let's denote the city population in a given year as [tex]\( C_n \)[/tex] and the suburban population as [tex]\( S_n \),[/tex] where [tex]\( n \)[/tex] represents the number of years since 2015. The initial populations in 2015 are given as [tex]\( C_0 = 10,000,000 \)[/tex] and[tex]\( S_0 = 800,000 \)[/tex].

Each year, 6% of the city's population moves to the suburbs, which can be represented as [tex]\( 0.06C_n \)[/tex]. Similarly, 4% of the suburban population moves into the city, which is [tex]\( 0.04S_n \).[/tex]

The difference equations describing the change in population each year are:

[tex]\[ C_{n+1} = C_n - 0.06C_n + 0.04S_n \][/tex]

[tex]\[ S_{n+1} = S_n + 0.06C_n - 0.04S_n \][/tex]

Now, let's calculate the populations for 2016 (one year after 2015,[tex]\( n = 1 \))[/tex]:

[tex]\[ C_1 = C_0 - 0.06C_0 + 0.04S_0 \][/tex]

[tex]\[ S_1 = S_0 + 0.06C_0 - 0.04S_0 \][/tex]

Plugging in the initial values:

[tex]\[ C_1 = 10,000,000 - 0.06 \times 10,000,000 + 0.04 \times 800,000 \][/tex]

[tex]\[ S_1 = 800,000 + 0.06 \times 10,000,000 - 0.04 \times 800,000 \][/tex]

Calculating the values:

[tex]\[ C_1 = 10,000,000 - 600,000 + 32,000 \][/tex]

[tex]\[ S_1 = 800,000 + 600,000 - 32,000 \][/tex]

[tex]\[ C_1 = 9,432,000 \][/tex]

[tex]\[ S_1 = 1,368,000 \][/tex]

Next, we calculate the populations for 2017 [tex](\( n = 2 \)):[/tex]

[tex]\[ C_2 = C_1 - 0.06C_1 + 0.04S_1 \][/tex]

[tex]\[ S_2 = S_1 + 0.06C_1 - 0.04S_1 \][/tex]

 Using the populations from 2016:

[tex]\[ C_2 = 9,432,000 - 0.06 \times 9,432,000 + 0.04 \times 1,368,000 \][/tex]

[tex]\[ S_2 = 1,368,000 + 0.06 \times 9,432,000 - 0.04 \times 1,368,000 \][/tex]

Calculating the values:

[tex]\[ C_2 = 9,432,000 - 565,920 + 54,720 \][/tex]

[tex]\[ S_2 = 1,368,000 + 565,920 - 54,720 \][/tex]

[tex]\[ C_2 = 9,792,000 \][/tex]

[tex]\[ S_2 = 807,360 \][/tex]

Step-by-step explanation:

int age; \\ it is declared as integer because 18 is an integer value

age=18; \\ initialized as 18 is stored in the variable 'age'

float weight; \\ weight is declared as float because it's value is floating or decimal value which cannot be declared as integer value

weight=114.5F; \\ F shows that it's single floating type value of 32 bits, if F is not written then it means it double floating type value which is 64 bits long

In order to declare and initialize two variables, one as an integer named 'age' initialized to '18' and the other named 'weight' initialized to '114.5', you'd write 'int age = 18;' and 'double weight = 114.5;' respectively.

To declare and initialize two variables in a programming language such as Java or C++, you would use the following syntax:

int age = 18;

double weight = 114.5;

The keyword 'int' declares an integer variable, and 'double' declares a variable for floating-point numbers. After the variable name, an equals sign ('=') is used to assign or initialize the variable to a specific value.

Step-by-step explanation:

- Generally, the agent of a COMMA + VERBing modifier must be the nearest preceding SUBJECT.

- B and C: The 32 species...include the animal known as the killer whale, growing

- Here, COMMA + growing seems to refer to the 32 species -- the nearest preceding subject -- implying that the SPECIES are GROWING.

Not the intended meaning.

- The intended meaning of the original sentence is that THE KILLER WHALE can GROW.

Eliminate B and C.

- In D and E, includes (singular) does not agree with the 32 species (plural).

Eliminate D and E.

- the correct answer is A

The correct answer is option (A). include the animal known as the killer whale,which can grow to be 30 feet long

To determine this, we need to ensure the sentence maintains proper subject-verb agreement and logical consistency. The primary subject is 'The 32 species that make up the dolphin family,' which is plural.

Therefore, the verb 'include' is correct, rather than 'includes' which would be for a singular subject.

Additionally, 'which can grow to be 30 feet long and is' clearly and correctly describes the killer whale.

The correct answer to this question is (A) include the animal known as the killer whale, which can grow to be 30 feet long and is.

Answer:

42 games

Step-by-step explanation:

If the college basketball team has won 14 games and lost 6 games,

The Probability of recording a win is given as:

Probability(of a win)[tex]=\frac{Number of Outcomes }{Total Number o trials}[/tex]=[tex]\frac{14}{20}[/tex]

In experimental probability, this can also be taken as the Relative Frequency of a win.

Therefore: Number of Expected Wins

=Relative Frequency of  a win X Total Number of Trials

[tex]\frac{14}{20}X60=42[/tex]

The team would expect to win 42 games in a 60 game schedule

Final answer:

The team would win 35 games in a 50 game schedule.

Explanation:

To find out how many games the team would win in a 50 game schedule, we can use a proportion. The team has won 14 out of 20 games so far, which can be written as 14/20. We can set up a proportion with x representing the number of games the team would win in a 50 game schedule:

14/20 = x/50

Now we can cross-multiply and solve for x:

20x = 14 * 50

20x = 700

x = 700/20

x = 35

So, if they continue to win at this rate, the team would win 35 games in a 50 game schedule.

Here, boy child is denoted by "b" and girl child by "g".

Total number of outcomes are 8.

Number of outcomes that show exactly boys = 3.

Number of outcomes that show exactly 3 boys = 1

Number of outcomes that show exactly 1 boy = 3.

Thus, the required probabilities can be calculated as:

(a)

[tex]\\P( Exactly 2 boys) =\frac{3}{8}[/tex]

(b)

[tex]P( Exactly 3 boys) =\frac{1}{8}[/tex]

(c)

[tex]P(Exactly 1 boy)= \frac{3}{8}[/tex]

Thus, the required probabilities are 3/8, 1/8 and 3/8 respectively.

This is a problem in Mathematics, specifically probability, at the High School level. The student is asked to calculate the probability of certain gender distributions among three children. The outcomes are determined and the respective probabilities calculated: the probability for exactly 2 boys and 1 boy is found to be 3/8 each, while for exactly 3 boys it's 1/8.

This question pertains to the understanding of probability in a specific scenario: calculating the likelihood of certain outcomes when a couple has three children. Given that each child can be a boy or a girl (2 possibilities), and there are three children, there are 2^3 or 8 total possible outcomes.

a. To find the probability of having exactly 2 boys, we count the outcomes where that is the case: BBG, BGB, GBB. This is three outcomes, so the probability is 3/8.

b. There is only one outcome where all three children are boys (BBB), therefore the probability of exactly 3 boys is 1/8.

c. The outcomes with exactly 1 boy are BGG, GBG, GGB. This gives us three outcomes, hence the probability is also 3/8.

Answer: the price of a bag of popcorn is $5.3

Step-by-step explanation:

Let x represent the price of one drink.

Let y represent the price of one bag of popcorn.

Robert spends a total of $65.25 on 4 drinks and 9 bags of popcorn. This is expressed as

4x + 9y = 65.25- - - - - - - - - - - - - - -1

Robert spends a total of $51.75 on 8 drinks and 3 bags of popcorn.

This is expressed as

8x + 3y = 51.75- - - - - - - - - - - - - - -2

Multiplying equation 1 by 8 and equation 2 by 4, it becomes

32x + 72y = 522

32x + 12y = 207

Subtracting, it becomes

60y = 315

y = 315/60

y = 5.25

Answer:

T = 25 + 12 * h

Step-by-step explanation:

To find the rate of the tuner it is necessary to go to an equation:

First would be the full rate that has a value of 25. And for every hour that is 12.

That is to say:

T = 25 + 12 * h

h being the hours it takes to tune the piano. And this equation would reprehend what the piano tuner

Out of a dozen eggs, with 4 being white, the fraction that represents the brown eggs is 8/12. Simplified, this fraction is 2/3.

The question is asking us to find what fraction of the eggs are brown if there are 4 white eggs out of a dozen in a basket. Since there are 12 eggs in a dozen, and we know 4 are white, we can subtract the 4 white eggs from the total to find out how many are brown.

12 eggs (total) - 4 white eggs = 8 brown eggs.

Therefore, the fraction of the basket that contains brown eggs is 8/12. To simplify this fraction, we look for the greatest common divisor of both the numerator (8) and the denominator (12), which is 4. Dividing both by 4, we get:

8 ÷ 4 = 2

12 ÷ 4 = 3

So the fraction of the eggs that are brown in simplest form is 2/3.

All right triangles are similar

(1)Let BD=x

Triangle ABC and DBC are similar

When two triangle are similar then , the ratio of their corresponding sides are equal.

[tex]\frac{12}{8}=\frac{8}{x}[/tex]

[tex]x=\frac{8\times 8}{12}=\frac{64}{12}=5.3 ft[/tex]

[tex]x=\frac{64}{12}\times 12=64 inches[/tex]=5 ft 4in

1 feet=12 inches

(2)In triangle DBC

[tex]CD^2=BC^2+DB^2[/tex]

Using Pythagoras theorem  

[tex](hypotenuse)^2=(Base)^2+(perpendicular\;side)^2[/tex]

[tex]CD^2=(8)^2+(5.3)^2[/tex]

[tex]CD=\sqrt{64+28.09)}=9.6 feet[/tex]

Hence, the length of support wire=9.6 feet

The distance from point B that point D should be placed in the triangle is 5 feet 4 inches.

The distance from point B that point D should be placed in the triangle will be calculated thus:

Let the distance be represented by x

12/8 = 8/x

x = (8 × 8) / 12

x = 5 ft 4 in

The length of the support wire will be calculated thus:

CD² = 8² + 5.3²

CD² = 64 + 28.09

CD² = 92.09

CD = ✓92.09

CD = 9.6 feet

Therefore, the length of the support wire is 9.6 feet.
