Answer:
f(x) = y + (x*p)
Step-by-step explanation:
Since we are not given actual values we will need to make the function with only variables. Each variable will represent the following...
Fixed Cost: y
Cost per charm: p
Number of charms: x
Therefore, using the variables mentioned above we can combine them into the following linear function using the number of charms as our main input for our function...
f(x) = y + (x*p)
Y-y1=m(x-x1)
m= slope =-3
y-y1=-3(x-x1),
y1=-7, x1=5
y--7=-3(x-5)
y+7=-3(x-5) this is C
Answer:
a=2.4
Step-by-step explanation:
Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
a) The formula for z -score :

Sample size = 1
For x= 63 in. ,

The p-value = 

Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,

The p-value = 

Thus , the probability is approximately=0.8810.
