Answer:
C = 0.175x + 5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>A phone company has a monthly cellular data plan where a customer pays a flat monthly fee $5 and then a certain amount of money per megabyte (MB) of data used on the phone</em>
Given:
- Customer uses 80 MB
- The monthly cost will be $19.00 (flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone)
So let:
- C is the cost of the data plan
- x is amount of money per megabyte (MB)
We can form the standard equation:
C = mx + b <=> C = mx + 5
In this situation, we have:
19 = m*80 + 5
<=> m = 0.175
So the a linear equation is: C = 0.175x + 5
Hope it will find you well
Answer:
Step-by-step explanation:
Given that the random variable X is normally distributed, with
mean = 50 and standard deviation = 7.
Then we have z=
Using this and normal table we find that
a)
b) When z=0.02
we get
c) 90th percentile z value =1.645
90th percentile of X
Answer:
um...10
Step-by-step explanation:
C because it has no x-intercept or no y-intercept .
that looks correct to me double check your work to see if it's right or use photomath I use it and it helps A LOT
