For a runner traveling 5 feet per second, how long, in minutes, would it take to run 600 feet?

yanalaym [24]

First find how many seconds it would take by dividing distance by rate:

600 feet / 5 feet per second = 120 seconds.

Convert seconds to minutes: 1 minute = 60 seconds:

120 seconds / 60 seconds per minute = 2 minutes

. The time taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal probability distributio

ki77a [65]

Answer:

Probability that the sample average time taken is less than 11 minutes for Day 1 is 0.86864.

Probability that the sample average time taken is less than 11 minutes for Day 2 is 0.88877.

Step-by-step explanation:

We are given that the time taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal probability distribution with average time 10 minutes and a standard deviation of 2 minutes.

Also, five individuals fill out the form on Day 1 and six individuals fill out the form on Day 2.

(a) Let $\bar X$ = sample average time taken

The z score probability distribution for sample mean is given by;

Z = $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

where, $\mu$ = population mean time = 10 minutes

$\sigma$ = standard deviation = 2 minutes

n = sample of individuals fill out form on Day 1 = 5

Now, the probability that the sample average time taken is less than 11 minutes for Day 1 is given by = P( $\bar X$ < 11 minutes)

P( $\bar X$ < 11 minutes) = P( $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ < $\frac{11-10}{\frac{2}{\sqrt{5} } }$ ) = P(Z < 1.12) = 0.86864

The above probability is calculated by looking at the value of x = 1.12 in the z table which has an area of 0.86864.

(b) Let $\bar X$ = sample average time taken

The z score probability distribution for sample mean is given by;

Z = $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

where, $\mu$ = population mean time = 10 minutes

$\sigma$ = standard deviation = 2 minutes

n = sample of individuals fill out form on Day 2 = 6

Now, the probability that the sample average time taken is less than 11 minutes for Day 2 is given by = P( $\bar X$ < 11 minutes)

P( $\bar X$ < 11 minutes) = P( $\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }$ < $\frac{11-10}{\frac{2}{\sqrt{6} } }$ ) = P(Z < 1.22) = 0.88877

The above probability is calculated by looking at the value of x = 1.22 in the z table which has an area of 0.88877.

An online electronics store bought 20 keyboards and 15 phone chargers for $125 and then sold each keyboard for $35 and each phon

Bess [88]

(20)(35) + (15)(15) - 125

This is right because the store bought 20 keyboards and sold each one for 35 dollars, and bought 15 phone chargers and sold each one for 15 dollars. so, 20 x 35 = 700 and 15 x 15 = 225. We use - 125 because we used that money to buy the products, so we need to subtract that out of the profit we are going to get. 700 - 225 = 925. Now we subtract the money we used, 925 - 125 = 800. The profit they gained was 800 dollars!
