Complete Question:

The only types of vehicles sold at a certain dealership last month were sedans, trucks, and vans. If the ratio of the number of sedans to the number of trucks to the number of vans sold at the dealership last month was 4:5:7, respectively, what was the total number of vehicles sold at the dealership last month?

1) The number of vans sold at the dealership last month was between 10 and 20.

2) The number of sedans sold at the dealership last month was less than 10.

Answer:

The total number of vehicles sold = 32

Step-by-step explanation:

Since the ratio of sales is 4:5:7

Let m be a common factor

The number of sedans sold = 4m

The number of trucks sold = 5m

The number of vans sold = 7m

In (1)

Since the number of vans sold was between 10 and 20. i.e 10 ≤ 7m ≤20

The only multiple of 7 between 10 and 20 is 14

Therefore, 7m = 14; m=2

in (2)

The number of sedans sold was less than 10 i.e. 0 < 4m < 10

There are two multiples of 4 between 0 and 10, they are 4 and 8

for 4m = 4; m=1

for 4m = 8; m=2

m = 2 is the only consistent value in (1) and (2)

The number of sedans sold = 4m = 4 *2 = 8

The number of trucks sold = 5m = 5 * 2 = 10

The number of vans sold = 7m = 7*2 = 14

The total number of vehicles sold = 8 + 10 + 14

The total number of vehicles sold = 32

Answer: $17505 must be deposited today.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited.

From the information given,

A = 30000

r = 8% = 8/100 = 0.08

n = 1 because it was compounded once in a year.

t = year

Therefore,.

30000 = P(1 + 0.08/1)^1 × 7

30000 = P(1.08)^7

30000 = 1.7138P

P = 30000/1.7138

P = $17505

Final answer:

To have $30,000 in 7 years for a down payment on a house, approximately $19,882.68 must be deposited today into an account with annual compounding and an APR of 8%.

Explanation:

To calculate the amount that must be deposited today, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the amount of money desired, P is the principal amount (the amount to be deposited), r is the annual interest rate (in decimal form), n is the number of times the interest is compounded per year, and t is the number of years. In this case, A = $30,000, r = 0.08 (8% as a decimal), n = 1 (compounded annually), and t = 7 years:

A = P(1 + r/n)^(nt) ⇒ $30,000 = P(1 + 0.08/1)^(1*7)

Now, we can solve the equation for P:

P = $30,000 / (1 + 0.08/1)^(1*7) ≈ $19,882.68

Therefore, approximately $19,882.68 must be deposited today to have $30,000 in 7 years for the down payment on a house.

Given:

Side lengths of cube = [tex]\frac{1}{4} \ foot[/tex]

The part of the truck that is being filled is in the shape of a rectangular prism with dimensions of 8 ft x 6 1/4 ft x 7 1/2 ft.

Question asked:

What is the greatest number of packages that can fit in the truck?

Solution:

First of all we will find volume of cube, then volume of rectangular prism and then simply divide the volume of prism by volume of cube to find the greatest number of packages that can fit in the truck.

[tex]Volume\ of\ cube =a^{3}[/tex]

                          [tex]=\frac{1}{4} \times\frac{1}{4}\times \frac{1}{4} =\frac{1}{64} \ cubic \ foot[/tex]

Length = 8 foot, Breadth = [tex]6\frac{1}{4} =\frac{25}{4} \ foot[/tex], Height =[tex]7\frac{1}{2} =\frac{15}{2} \ foot[/tex]

[tex]Volume\ of\ rectangular\ prism =length\times breadth\times height[/tex]

                                                [tex]=8\times\frac{25}{4} \times\frac{15}{2} \\=\frac{3000}{8} =375\ cubic\ foot[/tex]

The greatest number of packages that can fit in the truck = Volume of prism divided by volume of cube

The greatest number of packages that can fit in the truck = [tex]\frac{375}{\frac{1}{64} } =375\times64=24000\ pieces\ of\ cube[/tex]

Thus, the greatest number of packages that can fit in the truck is 24000 pieces.

Step-by-step explanation:

The first subtraction was correct:

  36 -7 3/4 = 28 1/4

The second subtraction needs to be revisited.

Answer:

a) [tex]\hat \mu = \bar X = 145[/tex]

b) [tex]145-1.64\frac{35}{\sqrt{25}}=133.52[/tex]  

[tex]145+1.64\frac{35}{\sqrt{25}}=156.48[/tex]  

So on this case the 90% confidence interval would be given by (133.52;156.48)  

Step-by-step explanation:

Previous concepts  

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

[tex]\bar X=145[/tex] represent the sample mean  

[tex]\mu[/tex] population mean (variable of interest)  

[tex]\sigma=35[/tex] represent the population standard deviation  

n=25 represent the sample size  

a) For this case the best point of estimate for the population mean is the sample mean:

[tex]\hat \mu = \bar X = 145[/tex]

b) Calculate the confidence interval

The confidence interval for the mean is given by the following formula:  

[tex]\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}[/tex] (1)  

Since the confidence is 0.90 or 90%, the value of [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that [tex]z_{\alpha/2}=1.64[/tex]

Now we have everything in order to replace into formula (1):  

[tex]145-1.64\frac{35}{\sqrt{25}}=133.52[/tex]  

[tex]145+1.64\frac{35}{\sqrt{25}}=156.48[/tex]  

So on this case the 90% confidence interval would be given by (133.52;156.48)  

Final answer:

The trigonometric functions and their inverse functions are related to each other because they undo each other's actions. Inverse trigonometric functions give the angle whose trigonometric ratio is a given value. The domains and ranges of inverse trigonometric functions are restricted to ensure that they are well-defined.

Explanation:

The trigonometric functions and their inverse functions are related to each other because they undo the actions of the other function. Let's take the sine function as an example. The sine function takes an angle as input and gives the ratio of the opposite side to the hypotenuse as output. Its inverse function, arcsine, takes a ratio as input and gives the angle whose sine is that ratio as output.

These comparisons make sense in the light of the definition of the inverse of a function because an inverse function undoes the action of the original function. In the case of trigonometric functions, they represent a ratio between the sides of a right-angled triangle, and their inverses give the corresponding angle.

The domains and ranges of the inverse trigonometric functions make sense in relation to their parent functions because they are restricted to a specific range to ensure that the inverse function is well-defined. For example, the domain of arcsine function is [-1, 1] because the output of sine function is always between -1 and 1. By restricting the domain, we can ensure that the inverse function is a one-to-one mapping and has a well-defined output for each input.

Answer:

The -15°C temperature of the ice in their snow cones mean that the temperature of that ice is 15° below the freezing point of water.

Step-by-step explanation:

It is explained that Celsius scale was calibrated based on water. The scientists use 0°C to represent the freezing point of water and subsequently use positive numbers to indicate temperatures above the freezing point of water and negative numbers to indicate temperatures lower than the freezing point of water.

So, a temperature of -15°C simply means that the temperature is 15° lower than the freezing point of water.

Answer: the probability that exactly 2 buyers would prefer red is 0.0320

Step-by-step explanation:

We would assume a binomial distribution for the color preferences of new car buyers. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 40% = 40/100 = 0.4

q = 1 - p = 1 - 0.4

q = 0.6

n = 14

x = r = 2

Therefore,

P(x = 2) = 14C2 × 0.4^2 × 0.6^(14 - 2)

P(x = 2) = 91 × 0.16 × 0.0022

P(x = 2) = 0.0320

Answer:

  y = 4x -3

Step-by-step explanation:

The line perpendicular to the given line can be written as the same equation with the coefficients of x and y swapped, and one of them negated. The constant may be different, so we'll call it "c".

  4x -y +c = 0 . . . . . line perpendicular to that given

The y-intercept of the second given line can be found by setting x=0. That gives the equation -y -3 = 0. The perpendicular line with x=0 would have equation ...

  -y +c = 0

Comparing these two tells us c = -3.

So, the general form of the perpendicular line we want is ...

  4x -y - 3 = 0

We can add y to put this in slope-intercept form:

  y = 4x -3

The average rate of change of f over intervals of x from x = 3 to  = 3.5 is - 159.

Given that the function is,

f (x) = - 5x³

Used the formula for the average rate of change of function f at interval [a, b] is,

f' (x) = [ f (b) - f (a) ] / (b - a)

Here, f (x) = - 5x³

At x = 3;

f (3) = - 5 × 3³

= - 135

At x = 3.5;

f (3.5) = - 5 × (3.5)³

= - 214.4

Hence, the average rate of change of f over intervals of x from x = 3 to  = 3.5 is,

f ' (x) = [- 214.5 - (- 135)] / (3.5 - 3)

Final answer:

The average rate of change of the function f(x) = -5[tex]x^3[/tex] from x = 3 to x = 3.5 is -158.75.

Explanation:

The average rate of change (ARoC) can be determined using the formula:

ARoC = (f(x2) - f(x1)) / (x2 - x1)

In this case, the given function is f(x) = -5x^3. To find the ARoC from x = 3 to x = 3.5, substitute these values into the formula:

ARoC = (-5[tex](3.5)^3 - (-5(3)^3)[/tex]) / (3.5 - 3)

Simplifying the equation gives:

ARoC = (-5(42.875) - (-5(27))) / (0.5)

ARoC = (-214.375 + 135) / 0.5

ARoC = -79.375 / 0.5

ARoC = -158.75

Therefore, the average rate of change of f(x) from x = 3 to x = 3.5 is -158.75.

e) 0.0238

f) 0.2005 = 20.05% probability that the proportion of people in the sample with a high school diploma is less than 85%.

-------------------------------------

The Central Limit Theorem establishes that for a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex] , if [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

In this problem:

Item a:

[tex]np = 200(0.87) = 174[/tex]

Item b:

This is:

[tex]n(1-p) = 200(0.13) = 26[/tex]

Item c:

Since both [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], the central limit theorem is applied, and the sampling distribution can be approximated by a normal distribution.

Item d:

The mean is:

[tex]\mu = p = 0.87[/tex]

Item e:

The standard deviation is:

[tex]s = \sqrt{\frac{0.87(0.13)}{200}} = 0.0238[/tex]

Item f:

Using z-scores, the probability is the p-value of Z when X = 0.85.

We have that:

Since, time can not be negative, so the required time is t = 2 seconds.

Final answer:

To find the time it takes for the object to travel 72 feet based on the given distance formula d=4t+16t², you can solve for t by substituting the distance value of 72 feet into the formula and solving for t.

Explanation:

Distance: To find the time it takes for the object to travel 72 feet, we can set the distance formula d = 4t + 16t² equal to 72 feet and solve for t.

Step-by-step explanation:

Given: d = 4t + 16t² and d = 72 feet

Substitute d = 72 into the formula: 72 = 4t + 16t²

Rearrange the equation: 16t² + 4t - 72 = 0

Solve for t using the quadratic formula or factoring.

The solutions for t will give you the time it takes for the object to travel 72 feet.

The probability that both of the interviewed students are from Middle Georgia State College is 2/7 or 0.2857 rounded to four decimal places.

To calculate the probability that both interviewed students are from Middle Georgia State College, one would use the formula for conditional probability, considering the process as two sequential events. The first student being from the college and then the second one, given the first is already from the college. Since there are four students from the college out of a total of seven, the probability of picking one Middle Georgia State College student first is 4/7.
