Answer:
It's c) y = 15x +200
Step-by-step explanation:
First divide the total cost by the number of students using two values of the table:
1500/100 = 15
This is the number that multiply x in the equation.
In the options given, there is just one equation that have 15 multipling x, so that must be the answer
Answer:
I'm only going to find the value of each variable
Step-by-step explanation:
V,Z,W,Y=39
X=94
Sorry, I didn't know how to explain the relevant angle relationships. '-' :(
Answer:
The probability that it would take more than four hours to construct a soapbox derby car = 0.1587 or 15.87
Step-by-step explanation:
Given -
Mean
= 3 hours
Standard deviation
= 1 hours
Let X be the no of hours to construct a soapbox derby car
the probability that it would take more than four hours to construct a soapbox derby car =
= 
=
Put 
= 1 -
= 1 - .8413 Using z table
= 0.1587
Here the value of 3 is =3/10
Then 100 fold of 3/10=3/10*100=30
So, the number 26538,532,97436 etc. has that property.
