Answer:

The correct option is d) 0.0253

Step-by-step explanation:

Consider the provided information.

When two events, X and Y, are dependent, then the probability of both occurring is: P(X \cap Y)  =  P(X) \cdot P(Y|X)

All plan to attend college some time; however, 77% plan to go to college immediately following high school.

Let X represents the Plan to go to college.

P(X) = 0.77

P(X') = 1 - 0.77 = 0.23

Of those who plan to attend college immediately following high school, 18% plan to major in Math. Of those who do not plan to attend college immediately following high school, 11% plan to major in Math.

Let Y represents Major in Math.

P(Y|X) = 0.18 and P(Y|X') = 0.11

Therefore the required probability is:

P(X'\cap Y) = P(X')P(Y|X') \\P(X'\cap Y)= 0.11\times 0.23 = 0.0253

Hence, the correct option is d) 0.0253

If a wagon wheel has a diameter of 70cm, how many revolutions would it take to travel 66 METERS?
ddd [48]

Answer:

30 revolutions

Step-by-step explanation:

to calculate the revolution of the wheels in 66 metres we need to get the circumference

circumference = 2πr, r = radius (diameter divided by 2) but from the formula of circumference we ca rewrite it as πd= 3.14 x 70 = 219.8cm

next convert 66 metres to cm

100cm = 1m

x= 66m

cross multiply

x= 66m x100cm/1m= 6600cm

revolutions in 66metres = 6600cm/219.8cm = 30.0272975 ≅30 revolutions
