20 1/3 + x = -9 round your answer to the nearest hundredth

nadya68 [22]

Answer:

I would think it's X= -29 1/3

Step-by-step explanation:

You have 20 1/3 already, and to get to a negative when you have a positive number, to the positive you would need to add a larger negative. (If that makes any sense, it's hard to explain.) So you have to get rid of the 20 1/3 and you have to get to -9, so I would add a 9 to 20 1/3 to get 29 1/3, and make that number negative because then it will cancel the positive out. Making it -9.

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%
