The mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.
Given,
number of workers chosen , n=12
percentage of respondents =62%

then,
probability of respondents ,
a)calculating mean,
b)calculating standard deviation,
Thus, the mean and standard deviation of number who find their jobs stressful are 7.44 and 1.6814 respectively.

5 and 85/100
Now simplify by dividing both by 5
Answer is
5 and 17/20
Step-by-step explanation:
The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.
Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.
