Answer: a. 0.40 b. 0.23 c . 0.435 d . 0.25
Step-by-step explanation:
melanin content Total
high low
moisture high 13 10 23
content low 47 30 77
Total 60 40 <u> </u><u>100</u>
Let A denote the event that a sample has low melanin content, and let B denote the event that a sample has high moisture content.
a) Total skin samples has low melanin content = 10+30=40
P(A)=
b) Total skin samples has high moisture content = 13+10=23
P(B) =
c) A ∩ B = Total skin samples has both low melanin content and high moisture content =10
P(A ∩ B) =
Using conditional probability formula , 
d) 
Answer: 10x + 7
Step-by-step explanation:

Answer:
10,466.7 in^3
Step-by-step explanation:
The volume of a cone is given by ...
V = (1/3)πr^2·h
where r is the radius and h is the height. Using your numbers, we have ...
V = (1/3)(3.14)(20 in)^2·(25 in) = 10,466.7 in^3
_____
A more accurate value of π will give a different result.
Answer:
53°, 127°, 127°
Step-by-step explanation:
<u>Two intersecting lines form two pairs of angles:</u>
- Pair of vertical angles. They are opposite to each other and are equal
- Pair of adjacent angles which are supplementary angles and their sum is 180°
<u>So if one of the angles is measured 53°, then the other angles are:</u>
- 53°- vertical angle with the first one
- 180° - 53° = 127°
- 180° - 53° = 127°
