Answer:

0.006946

Step-by-step explanation:

Given that :

W = normally distributed random variable

Mean(m) = 22

Variance = 25 ; standard deviation =√variance ;

Standard deviation (σ) = √25 = 5

Probability that W < 9.7

x = 9.7

Zscore = (x - m) / σ

Zscore = (9.7 - 22) / 5

Zscore = - 12.3 / 5

Zscore = - 2.46

P(Z < - 2.46) = 0.006946

Answer:

Fabric used by each each player for headband is 16.51 inches and fabric used for wristband is 1.99 inches

Step-by-step explanation:

In first case it is given that there are  players and 2 coaches

So total number = 44+2 = 46

It is given that 759.46 inches of fabric is used on headbands for 44 players and 2 coaches

So fabric used by each player =\frac{759.46}{46}=16.51inches

Now in second 87.64 inches fabric is used for 44 players

So fabric used by each players =\frac{387.64}{44}=1.99inches

So fabric used by wristband is 1.99 inches

Shalnov [3]
Willow = 63in

Jayder = 6ft 5in

1 foot equals 12 inches

6x12=72

So 72 inches plus 5 inches equals 77

77 - 63 = 14

Jayden is 14 inches taller
