Answer:
1.75,0.625
Step-by-step explanation:
Given that a couple plans to have children until they get a girl, but they agree that they will not have more than three children even if all are boys.
a) The couples can have
X I girl I boy, II girl I,II boys, III girl I,II,III boys
Pr. 0.5 0.25 0.125 0.125
b) Expected no of children
=
c)Expected number of boys
= 
The measure of the angles are 56.25° and 33.75°.
<h3>How to calculate the angles?</h3>
The value in a complementary angle is equal to 90°.
Let the first angle = x
The second angle will be: 1 - (40% × x) = 1 - 0.4x = 0.6x
Therefore, they'll be added together as follows:
x + 0.6x = 90°
1.6x = 90°
Divide
x = 90/1.6
x = 56.25
The second angle will be:
= 0.6x
Since x = 56.25, this will be used in the illustration below.
= 0.6x
= 0.6 × 56.25
x = 33.75
Therefore, the second angle is 33.75.
This illustrates the concept of complimentary angles.

Answer:
A&E
Step-by-step explanation:
The correct answer is that the variability is 2.0 times as large.
In the first set, the MAD is 1.2.
In the second set, the MAD is 0.6.
Dividing 1.2 by 0.6 gives us a factor of 2.
