Answer:
0.69
Step-by-step explanation:
A: obese
B: diabetes
P(A) = 61
P(B) = 31
P(A and B) = 23
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 61 + 31 - 23 = 69%=0.69
Answer:
40 mph.
Step-by-step explanation:
Hope I helped!
x-5=speed of car B
x=speed of car A
distance=speed times time
(x-5)(4.5)=(x)(4)
4.5x-22.5=4x
Multiply both sides by 2 to get rid of the decimals.
9x-45=8x
Subtract 8x from each side.
x-45=0 9 (A)
Add 45 to both sides.
x=45
Speed of car A=45 mph
Speed of car B=40 mph
