A large school district found that 88 of 100 randomly selected students at East High School had internet access
at home. A separate random sample from West High showed 79 of 100 students had internet access at home.
Administrators used those results to make a 90% confidence interval to estimate the difference between the
proportion of students at each school who have internet access at home (PE - Pw). The resulting interval was
approximately 0.09 0.086. They want to use this interval to test H, : PE = Pw versus H : PE + Pw at
the a = 0.10 significance level. Assume that all conditions for inference have been met.
Based on the interval, what do we know about the corresponding P-value and conclusion at the a=0.10
level of significance?

Answer:

Area = 1/10

Step-by-step explanation:

Since the Area of Triangle = 0.5*Base*Height

So, for our Problem

Base=3/5 km  ,  Height=1/3 km

Area =  0.5*Base*Height =   [tex]\frac{1}{2} *\frac{3}{5} *\frac{1}{3}[/tex]

Area = [tex]\frac{1}{2} *\frac{1}{5}=\frac{1}{10}[/tex] Square Kilometers

Answer:

24 is the correct answer

Step-by-step explanation:

Step-by-step explanation:

it must have 2 solutions, as the absolute value makes negative and positive values equal.

so, 2 approaches : positive and negative.

1. positive

(x + 2) + 4 = 11

x + 6 = 11

x = 5

2. negative

-(x + 2) + 4 = 11

-x - 2 + 4 = 11

-x + 2 = 11

-x = 9

x = -9

so, the third answer (x = 5, -9) is correct.

Answer:

c i think

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the cupcake cost = c

Let the milkshake cost = m

4c + 3 m = 23

2c + 4m = 24        multiply this equation by 2

2(2c + 4m = 24)

4c + 8m =     48        Now put the first equation underneath this one

4c + 3m = 23       Subtract

       5m = 25         Divide by 5

        m = 25/5

         m = 5

Use 2c + 4m = 24

m = 5

2c + 4*5 = 24            Combine

2c + 20 = 24             Subtract 20 from both sides

2c = 24 - 20

2c = 4                        Divide by 2

c = 4/2

c = 2

Answer:

20%

Step-by-step explanation:

$34 - $27.20 = $6.80

[tex]\frac{6.80}{34} = 0.2[/tex]

0.2 x 100 = 20%

:]

The percent of discount in the tag is, 20%.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The price on the tag was $34, but Mia paid $27.20 before tax.

Here, The discount price = $34 - $27.20

                                       = $6.8

Hence, The percent discount = 6.8 / 34 × 100

                                              = 20%

Step-by-step explanation:

Formula for circumference is C= pi x d

So C= pi x 10 = 31.4 in

Area = pi x r^2

= pi x (4)^2

= pi x 16

= 16 pi

= 50.24 in^2

Step-by-step explanation:

for a function every valid x value must have exactly 1 y value. several x values can have the same y value assigned but never can a x value have multiple y values assigned.

the valid x values for m are -3. -2, -1, 1, 2, 3.

and indeed, every one of these values has exactly one y value out of the possible 1, 4, 9 values.

so, m is a function.

but the inverse function turns the meaning of x and y upside-down. x becomes y and y becomes x.

and now we see that for the inverse the x value of 1 has two assigned y values (-1, 1).

the same for 4 (-2, 2) and 9 (-3, 3).

so, the inverse is NOT a function.

Answer:

so these are the answers

a. The determination of the break-even number of subscribers for Star Stream is as follows:

Break-even number of subscribers = Fixed Costs/Contribution Margin per subscriber

= 35,294,118 ($3,000,000,000/$85)

b. If Star Stream increases the annual content costs to $2,600,000,000, the break-even number of subscribers will increase to 42,352,941 subscribers.

= 42,352,941 ($3,600,000,000/$85)

c. The annual subscription needs to increase from $120 to $142 to maintain the same break-even as in (a).

The break-even analysis is a financial tool for determining the price level at which the total revenue equals the total costs (variable and fixed).

Using the break-even analysis model, one can determine the number of units to sell so that fixed costs are recovered.

Server lease costs per year = $100,000,000

Content costs per year = $2,000,000,000

Fixed operating costs per year = $900,000,000

Total fixed costs per year = $3,000,000,000

Bandwidth costs per subscriber per year = $15

Variable operating costs per subscriber per year = $25

Subscription per year = $125

Contribution margin per subscriber per year = $85 ($125 - $15 - $25)

Contribution margin ratio = 68% ($85/$125 x 100)

a. Determine the break-even number of subscribers.

b. Assume Star Stream planned to increase available programming and thus increase the annual content costs to $2,600,000,000. What impact would this change have on the break-even number of subscribers?

c. Assume the same content cost scenario in (b). How much would the annual subscription need to change to maintain the same break-even as in (a)?

Thus, with an annual subscription of $142, the variable cost of $40 per subscriber per year, contribution margin of $102 ($142 - $40), and a total fixed cost of $3,600,000,000, the break-even number of subscribers will remain 35,294,118 ($3,600,000,000/$102).

The purchase price of Wynona’s boots is 85.5% of the original price.

It is given that

The marked price of boots = $85.79

The percentage is a relative value indicating the hundredth parts of any quantity.
