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: Slope: 6-(-6)/2-(-4)=2
Slope:2
Write it in the standard form
Y=2x+b
Find the b
Substitute the y and x
6=2(2)+b
b=2
Here the equation=
Y =2x+2
Step-by-step explanation:
A is linear because nothing is being added or subtracted from the original number which is 3 to the power of x. All of the other answers are either adding or subtracted an addition number that do not cancel out.
