Answer:

10 2/3 cars

Step-by-step explanation:

We can use a ratio

4 cars            x cars

------------- = -----------

3 hours          8 hours

Using cross products

4 *8 = 3 *x

32 = 3x

Divide each side by 3

32/3 = 3x/3

Answer:

The price per wind chime that will maximize revenue = $ 315

Step-by-step explanation:

Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.

To find - Find the price per wind chime that will maximize revenue.

Proof -

Given that,

Total Wind chimes selling = 160

Price of each Wind chime = $150

Now,

Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.

So,

Let the price = 150 + 15x

So,

Number of wind Chimes sold per month = 160 - 5x

So,

Total Revenue, R = (150 + 15x)(160 - 5x)

                             = 24000 - 750x + 2400x - 75x²

                             = 24000 + 1650x - 75x²

⇒R(x) = 24000 + 1650x - 75x²

Differentiate R with respect to x , we get

R'(x) = 1650 - 150x

Now,

For Maximize Revenue, Put R'(x) = 0

⇒1650 - 150x = 0

⇒150x = 1650

⇒x = 1650/150

⇒x = 11

∴ we get

Price per Wind chime = $ 150 + 15(11)

                                    = $ 150 + 165

                                    = $ 315

So,

The price per wind chime that will maximize revenue = $ 315

Answer:

[tex]2 \frac{2}{7}[/tex] pounds, D

Step-by-step explanation:

1 pound of apples = 1.75 dollars.

Set the number of pounds of apples as x.

Then, we can write this equation.

1.75x = 4

[tex]\frac{7}{4}[/tex]x = 4

Divide both sides by [tex]\frac{7}{4}[/tex]

x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]

x = [tex]\frac{16}{7}[/tex]

x = [tex]2 \frac{2}{7}[/tex]

Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds

Answer:

[tex]M = 4.67[/tex]

Step-by-step explanation:

Given

[tex]Data: 3, 7, 8, 12, 16, 18[/tex]

Required

The mean absolute deviation

Start by calculating the mean

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{3+ 7+ 8+ 12+ 16+ 18}{6}[/tex]

[tex]\bar x = \frac{64}{6}[/tex]

[tex]\bar x = 10.67[/tex]

The mean absolute deviation is then calculated using:

[tex]M = \frac{1}{n}\sum\limits^n_{i=1}|x _i - \bar x|[/tex]

So, we have:

[tex]M = \frac{1}{6}(|3 - 10.67| +|7 - 10.67| + |8 - 10.67| + |12 - 10.67| + |16 - 10.67| + |18 - 10.67|)[/tex]

[tex]M = \frac{1}{6}(|-7.67| +|- 3.67| + |-2.67| + |1.33| + |5.33| + |7.33|)[/tex]

Remove absolute brackets

[tex]M = \frac{1}{6}(7.67 +3.67 + 2.67 + 1.33 + 5.33 + 7.33)[/tex]

[tex]M = \frac{1}{6}*28[/tex]

[tex]M = 4.67[/tex]

Answer:

{-2, 0, 4}

Step-by-step explanation:

Domain is defined as all the inputs possible to a function.

On a graph, you may know this as the value of x.

This means the domain is equal to all values of x that produce an output.

The only values of x that have a point on them is x = 4, x = 0, and x = -2, all of which have points on the x-value.

Answer:12/77

Step-by-step explanation:

The probability that a seventh grader chosen at random will play an instrument other than the Guitar is 0.76.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

The total event for seventh grade is given as,

Total = 9 + 9 + 11 + 9

Total = 38

The probability that a seventh grader chosen at random will play an instrument other than the Guitar is calculated as,

P = 9/38 + 11/38 + 9/38

P = 29/38

P = 0.76

Step-by-step explanation:

Answer:

Range → {7, 9, 0}

Step-by-step explanation:

Range of a function is a set of y-values or output values of the function.

Similarly, Domain of a function is the set of x-values or input values of the function.

Given points in the graph are (0, 7), (3, 9) and (9.4, 0)

Therefore, set of y-values {7, 9, 0) will be the Range.

Range of the function → {7, 9, 0}

Answer:

20 years

Step-by-step explanation:

9000/ 100= 900 = 10%

900/2= 450

450 x 2= 900

900 x 10= 9000

Now we multiply 10 by 2 because we doubled the value of our 450 into a 900 and now we get 20.

Compound interest is the interest that is made from the principal and the interest as well in consecutive years.

The number of years it will take to double the investment is 15 years.

Compound interest is the interest that is made from the principal and the interest as well in consecutive years.

We have,

Principal = $9000

Rate = 5%

The formula is given as:

A = p [tex](1 + \frac{R}{100} )^{n}[/tex]

n = number of years

Double the investment:

Amount = 2 x 9000 = 18000

Now,

18000 = 9000 [tex](1 + \frac{R}{100} )^{n}[/tex]

2 = [tex](1 + 0.05)^{n}[/tex]

2 = [tex]1.05^{n}[/tex]

Taking log on both sides.

[ log a² = 2 log a ]

log 2 = n log 1.05

0.30 = n 0.02

n = 0.30 / 0.02

n = 15

Thus,

The number of years it will take to double the investment is 15 years.
