In a question like this, you want to approach it with the equation "slope intercept form" which is
b = y-intercept
- the point where the line intercepts the y-axis
m = slope
I suggest using Desmos Graphing Calculator, it really helps and shows you a graphed equation. Let me know what you get!
Answer:
(1) a. 0.0009
(2) d. 0.640
(3)
- a. P(A and B) = 0.06.
- b. P(A or B) = 0.70.
(4)Not disjoint
(5) a. nearly 0.
(6)b. 0.919
Step-by-Step Explanation:
(1)Probability of a baby being born with a birth defect =3%=0.03
The probability that both babies have birth defects=0.03 X 0.03= 0.0009.
(2)The probability of contracting the influenza virus each year = 20%=0.2
Therefore, the probability of not contracting the influenza virus =1-0.2=0.8
The probability that neither baby catches the flu in a given year:
=0.8 X 0.8
=0.64
(3)
P(A)=0.1
P(B)=0.6
P(A or B)=P(A)+P(B)=0.1 + 0.6 =0.7
P(A and B)=P(A)XP(B)=0.1 X 0.6 =0.06
(4)
P(A)=0.2
P(B)=0.9
Event A and B cannot be disjoint.
(5)
The probability of an American woman aged 20 to 24 having Chlamydia infection 
The probability that three randomly selected women in this age group have the infection
(6)The probability of an American woman aged 20 to 24 not having Chlamydia infection 
The probability that three randomly selected women in this age group do not have the infection
39. If jim is twice older than mike then he is 11 years older. if he is 50, then subtract 11 AND THE ANSWER IS 39.
Hi there! The answer is 9 square units
To find the area of a triangle we use the following formula:
Area = 0.5 * base * height.
The base of this triangle:
AC = 6
The height of this triangle:
BD = 3
Filling in this formula gives us:
Area = 0.5 * 3 * 6 = 9
Therefore, the answer is 9 square units
