Answer: $\$\ 1000$

Step-by-step explanation:

Given

Molly down payment $=\$\ 2500$

Dealer's allowance $=\$\ 1500$

For loan amount , It is equal to the difference of molly down payment and dealer allowance

loan amount $=2500-1500$

loan amount $=\$\ 1000$

So, Molly needs $\$\ 1000$ loan

Victoria is interested in opening her own candy store. She has researched and found that of the 14 stores she investigated, the

Anna71 [15]

Answer:

99% confidence interval for the average start up cost is [76.575 , 123.425].

Step-by-step explanation:

We are given that of the 14 stores Victoria investigated, the average start up cost is 100 thousand dollars with a standard deviation of 29.1 thousand dollars.

So, the pivotal quantity for 99% confidence interval for the population average start up cost is given by;

P.Q. = $\frac{\bar X - \mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample average start up cost = 100 thousand dollars

$\sigma$ = sample standard deviation = 29.1 thousand dollars

n = sample of stores = 14

$\mu$ = population average start up cost

<em>So, 99% confidence interval for the average start up cost, </em> $\mu$ <em> is ;</em>

P(-3.012 < $t_1_3$ < 3.012) = 0.99

P(-3.012 < $\frac{\bar X - \mu}{\frac{s}{\sqrt{n} } }$ < 3.012) = 0.99

P( $-3.012 \times {\frac{s}{\sqrt{n} }$ < ${\bar X - \mu}$ < $3.012 \times {\frac{s}{\sqrt{n} }$ ) = 0.99

P( $\bar X-3.012 \times {\frac{s}{\sqrt{n} }$ < $\mu$ < $\bar X +3.012 \times {\frac{s}{\sqrt{n} }$ ) = 0.99

<u>99% confidence interval for</u> $\mu$ = [ $\bar X-3.012 \times {\frac{s}{\sqrt{n} }$ , $\bar X +3.012 \times {\frac{s}{\sqrt{n} }$ ]

= [ $100-3.012 \times {\frac{29.1}{\sqrt{14} }$ , $100+3.012 \times {\frac{29.1}{\sqrt{14} }$ ]

= [76.575 , 123.425]

Therefore, 99% confidence interval for the population average start up cost for a candy store is [76.575 , 123.425].

Please show your work! thank you

You want to write them both into slope intercept form (y=mx+b) so the first one is y=2x-9/2. For the second one you can start converting them until you get y=3x+kx+2 so you need to find the value of K that adds to to equal to 2 because parallel lines have the same slope so k would = -1

Cylinder A has radius r and height h as shown in the diagram. Cylinder B has radius 4r and height 4h. How many times greater is

svetlana [45]

Answer:

The surface area of Cylinder B is 16 times the surface area of Cylinder A

Step-by-step explanation:

<u>Note</u>: <em>It is assumed we are looking at the total surface area (but the answer would be same for both cases)</em>

<h3>Given</h3>

Cylinders A with radius - r, height - h,
Cylinder B with radius - 4r, height - 4h.

<h3>To find </h3>

The ratio of total surface areas of cylinder B to A

<h3>Solution</h3>

Total surface area of cylinder A is:

$S_A = 2\pi r(h + r)$

Total surface area of cylinder B is:

$S_B = 2\pi(4r)(4r + 4h) = 8\pi(4)(r + h) = 32\pi(r + h)$

Find the ratio of areas:

$\cfrac{S_B}{S_A} =\cfrac{32\pi(r+h)}{2\pi(r+h)} =16$
