Answer:
0.03 is the probability that for the sample mean IQ score is greater than 103.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 16
Sample size, n = 100
We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =

P( mean IQ score is greater than 103)
P(x > 103)
Calculation the value from standard normal z table, we have,

0.03 is the probability that for the sample mean IQ score is greater than 103.
Answer:
remaining cardboard area = 122.5πr²
Step-by-step explanation:
area of original rectangle = length * width
= 18r * 8r
= 144r²
- area of semi circle:
πr²
Here we have 3 semi circles with radius 3r:
- area of 3 semi circles: 3(
* π * (3r)²)
: 3(
* π * 9r²)
: 13.5πr²
- area of one semi circle with radius 4r:
(
* π * (4r)²)
(
* π * 16r²)
8πr²
- So the area of remaining cardboard:
area of rectangle - area of 4 semi circles
144r² - 13.5πr² - 8πr²
122.5πr²
Answer:
For question 13, it would be a) the angles are vertical.
