Answer:
- 1. 15
Step-by-step explanation:
Z score is used in statistic to calculate deviation of an observed value from mean value of sample of observation.
Mathematically it is given by
using the above formula and substituting the value of of
mean = $42,800
standard deviation = $8,365
observed value =$30,000
Z = (8,365 - 42,800) / $30,000
= - 34,435/ 30,000 = - 1. 14783
= - 1. 15 ( to the nearest hundredth)
- 1. 15 Z-Score would be used to determine the percentage of residents working in the technology sector who earn more than $30,000
Answer:
d. 72 in³
Step-by-step explanation:
To find the volume of a cylinder that a cone of volume 24 cubic inches fits in exactly inside of, we will follow the steps below:
From the question volume of the cone = 24 cubic inches
volume of a cone = πr²h
and volume of a cylinder = πr²h
This implies
volume of a cone = πr²h
= (volume of a cylinder)
volume of a cone = (volume of a cylinder)
24 = (volume of a cylinder)
multiply both-side of the equation by 3
24×3 = (volume of a cylinder)
72 =volume of a cylinder
Therefore volume of the cylinder that the cone fits exactly inside of is 72 cubic inches
