Answer:
The probability that a student takes Spanish given that the student is taking Computer Programming = 0.375
Step-by-step explanation:
Given -
Let event A = student takes Spanish
Event B = student takes Computer Programming
= student takes Computer Programming and Spanish
P(B) = 0.4 , = 0.15
What is the probability that a student takes Spanish given that the student is taking Computer Programming =
(Probability of an event occuring given that another event has already occured , we use condition probability )
=
= 0.375
The equation in slope-intercept form is y=2x-2
Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week
Solution:
Given that,
Kay spends 250 min/wk exercising
Therefore,
Exercising = 250 minutes per week
Ratio of time spent on aerobics to time spent on weight training is 3 to 2
Aerobics : weight training = 3 : 2
Let the time spent on aerobics be 3x
Let the time spent on weight training be 2x
Thus,
3x + 2x = 250
5x = 250
x = 50
Thus,
Time spent on aerobics = 3x = 3(50) = 150
Time spent on weight training = 2x = 2(50) = 100
Thus, Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week
