Answer:

B

Step-by-step explanation:

Charge of 9 gigs for A

find slope:

125 - 95/5 - 3 = 30/2 = $15/month

use point slope form with point (3,95) and slope 15:

y - y1 = m(x - x1)

y - 95 = 15(x - 3)

y - 95 = 15x - 45

 + 95           +95

y = 15x + 50

put 9 for x, gigs, in the new equation:

y = 15(9) + 50

y = 135 + 50

y = 185

$185 for opt A

Charge of 9 gigs for B

slope = 0

there is the fee of 150 so the equation is:

y = 0x + 150

Next find the price for 9 gigs

y = 9(0) + 150

y = 150

$150 for opt B

Charge of 9 gigs for C

use graph and the cost is about $157

A: $185

B: $150

C: $157

n a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cla
enyata [817]

Answer: the man's claim is true.

Step-by-step explanation:

Given that 30% of the well find water at a depth <=100 feet

P(X<=100) = 0.30

If the man's prediction work well the probability of finding well at less than 100 or equal should be high fwhen calculated from his results. So give 27 out of 80 wells

P(X<=100) = 27/80

P(X<=100) = 0.3375

Since 0.3375 > 0.3

The man's claim is true.
