The answer is
G = [m1(veca1a2) + m2 (veca3a4) + m3veca5a6)] / (m1 + m2 + m3)
G= m1x5 + m2 x 4sqrt (2) + m3x 3sqrt (2) / 16 = 35 +4 x 3.7x sqrt (2) + 5.3 x3 4sqrt (2) / 16 =35 + 36<span> sqrt (2) / 16
G = 53.09

Option D: 40+20w is the correct answer
Step-by-step explanation:
We have to convert the given statement in the problem to find the correct choice
Let w be the number of weeks
As Joe already has $40, it will be constant that will not change
And the money he saves in w weeks by saving 20 dollars per week will be:
20w
Combining the both terms we get the total cost as:
Hence,
Option D: 40+20w is the correct answer

5 Girls + 3 Boys =8 (sample size)
Probability of choosing 1 boy P(1 B) = 3/8
Probability of NOT CHOOSING ANY BOY = 1-3/8 =5/8
Now apply the binomial probability to choose 3 Boys:
8C3(3/8)³(5/8)⁵ ==>P(All boys) = 0.28
