Answer: 2.308 .
Step-by-step explanation:
Let X denotes the number of earthquakes in SanFernando valley region of Los Angeles in 1994.
Given: 
Probability is 0.87 that there will be at least 15 earthquakes .
i.e. 
![\Rightarrow\ P(\dfrac{X-\mu}{\sigma}\geq\dfrac{15-17.6}{\sigma})=0.87\\\\ \Rightarrow\ P(Z\geq\dfrac{-2.6}{\sigma})=0.87\ \ \ [Z=\dfrac{X-\mu}{\sigma}]](https://tex.z-dn.net/?f=%5CRightarrow%5C%20P%28%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5Cgeq%5Cdfrac%7B15-17.6%7D%7B%5Csigma%7D%29%3D0.87%5C%5C%5C%5C%20%20%5CRightarrow%5C%20P%28Z%5Cgeq%5Cdfrac%7B-2.6%7D%7B%5Csigma%7D%29%3D0.87%5C%20%5C%20%5C%20%5BZ%3D%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5D)
Z-value corresponding to p-value 0.87 is -1.1263 .
So, 

Hence, the required standard deviation = 2.308 .
Answer: Jamian bought 20 bagels and 15 donuts
Step-by-step explanation:
Using the equation below:
b + d = 35 ...... i
1.25b + 0.75d = 36.25 ....... ii
Multiply i by 1.25
Multiply ii by 1
1.25b + 1.25d = 43.75 ...... iii
1.25b + 0.75d = 36.25 ....... iv
Subtract iv from iii
0.50d = 7.50
d = 7.50 / 0.50
d = 15
Since b + d = 35
b = 35 - 15
b = 20
