What does proportional relationship means?

monitta

Answer:

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if: y = k x. for some constant k , called the constant of proportionality .

12- 8. 2. 4 8 10 Slope

S_A_V [24]

Step-by-step explanation:

what is the problem ? find the slope of the line ?

the slope is the ratio y/x of the y difference and the x difference between 2 points.

I see 2 points with seemingly integer coordinates.

one point is at (2, 6) as you marked it also on the sheet.

the other point is (6, 12).

so, when you go from point 1 to point 2, x changes by 4 units (from 2 to 6) and y changes by 6 units (from 6 to 12).

therefore, the slope is 6/4 = 3/2

The quotient of a number and 5 less 10 is 3

ohaa [14]

Quotient means the answer of diving two numbers.

We can write the equation as: n/5 - 10 = 3

~Add 10 to both sides

n/5 - 10 + 10 = 3 + 10

n/5 = 13

1/5n = 13

1/5n * 5 = 13 *

n = 65

Hope This Helped! Good Luck!

. 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.
