Answer:
a 17, b 10, c 15, d 20
Step-by-step explanation:
a^2+b^2=c^2
64+225 = 289
a = 17
36+64 = 100
b = 10
81+144 = 225
c = 15
256+144 = 20
Hope that helps
The answer to the problem is 2
Answer:
0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00
Step-by-step explanation:
Mean = 
Standard deviation = 
We are supposed to find the proportion of customer purchase amounts between $14.00 and $16.00
P(14<x<16)
Formula : 
At x = 14


Refer the z table for p value
P(x<14)=0.1922
At x = 16


Refer the z table for p value
P(x<16)=0.6141
P(14<x<16)=P(x<16)-P(x<14)=0.6141-0.1922=0.42
So, Option C is true
Hence 0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00
