Answer:
4h+17
Step-by-step explanation:
Hey There!
So to solve this problem we need to use distributive property
So we need to distribute the 3 to everything that is in the parenthesis ( h and 5)
3xh=3h
3x5=15
so now we have
3h +15 + h + 2
now we just combine like terms
3h+h=4h
15+2=17
So the answer is 4h+17
Using the normal distribution, it is found that there is a 0.877 = 87.7% probability of a bulb lasting for at most 569 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
![\mu = 540, \sigma = \sqrt{625} = 25](https://tex.z-dn.net/?f=%5Cmu%20%3D%20540%2C%20%5Csigma%20%3D%20%5Csqrt%7B625%7D%20%3D%2025)
The probability of a bulb lasting for at most 569 hours is the <u>p-value of Z when X = 569</u>, hence:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \frac{569 - 540}{25}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B569%20-%20540%7D%7B25%7D)
Z = 1.16
Z = 1.16 has a p-value of 0.877.
0.877 = 87.7% probability of a bulb lasting for at most 569 hours.

Answer:
1 I believe.
Step-by-step explanation:
6 + 5 = 11
5 + 6 = 11
11 - 5 = 6
11 - 6 = 5
