When that equation is graphed, it produces a straiught line. The slope
of the line is 5, and the line intersects the y-axis at y=6.

All function of type: y = ax + b

a = slope b = intersept

So:

slope = 5
intersept = 6

Step-by-step explanation:

A) opposite sides in a rectangle is always equal

B) 9x+12 = 4x +47

Transpose = 9x - 4x = 47 - 12

solve = 5x = 35

Divide both sides by 5

x = 7

B is the midpoint of AC. Find the length of the line segment AC IF AB = 48

Gala2k [10]

Answer:

AC=96

Step-by-step explanation:

If B is the midpoint of AC then AB is equal to BC there for you can find AC by adding AB and BC (AB+BC=AC) so in this case it would be 48+48=96

According to records kept by Mariposa County, the average (mean) amount of time that it takes for employees to be reimbursed for

Aloiza [94]

Answer:

The probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%

Step-by-step explanation:

Let $P(a \leq x \leq b)$ the probability of being reimbursed in an interval of a to b days, we want $P(0 \leq x \leq 42)$

First, standardize x by doing the change

$z=\frac{x-\mu}{\sigma}$

where $\mu$ is the mean of our original distribution and $\sigma$ the standard deviation. So

$z=\frac{x-36}{5}$

This change transforms the original distribution in a normal distribution N(0,1) with mean 0 and standard deviation 1.

This is done in order to easily compute the area under the normal curve.

Since,

$0 \leq x \leq 42\Rightarrow -36 \leq x -36 \leq 6\Rightarrow \frac{-36}{5} \leq \frac{x -36}{5} \leq \frac{6}{5}$

we then have

$-7.2 \leq z \leq 1.2$

And we want the area under the normal curve between -7.2 and 1.2. This can be done either by using a table or a computer, and we find this area is 0.8849,

Hence, the probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%
