Answer: 348in^2

Step-by-step explanation:

8 x 9 = 72

72 x 2 = 144in^2 (front and back)

8 x 6 = 48

48 x 2 = 96in^2 (sides)

9 x 6 = 54

54 x 2 = 108in^2 (top and bottom)

Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)

Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

o-na [289]

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).

Catherine paid $159.00 for an MP3 player. If the price paid includes a 6% sales tax, which of the following equations can be use

Colt1911 [192]

<u>ANSWER: </u>

The equation is y = 1.06x, so option D is correct.

<u>EXPLANATION:</u>

Given:

Amount Catherine is paid for an MP3 player=$159.00

The price paid includes a sales tax= 6%

To find:

Equations that can be used to determine the price of the MP3 player before tax?

Solution:

Now, we know that, total cost = selling price of item + sales tax on item

y = x + 6% of x

y = x + $\frac{6}{100}x$

y = x + 0.06x

y = 1.06x

Hence, the equation is y = 1.06x, so option D is correct.
