A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 p

lora16 [44]

Answer:

425 min
$80

Step-by-step explanation:

The equation to reflect the monthly plans:

Plan A f(x) = 0.16x + 12
Plan B g(x) = 0.12x + 29

We need to find the value of x when f(x) = g(x):

0.16x + 12 = 0.12x + 29
0.16x - 0.12x = 29 - 12
0.04x = 17
x = 17/0.04
x = 425 minutes

The cost is:

$0.16*425 + $12 = $80

Daily low temperatures in Columbus, OH in January 2014 were approximately normally distributed with a mean of 15.45 and a standa

Alona [7]

Answer: 12.10

Step-by-step explanation:

Given : Mean : $\mu = 15.45$

Standard deviation : $\sigma = 13.70$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x= 5 degrees

$z=\dfrac{5-15.45}{13.70}=-0.7627737226\approx-0.76$

For x= 10 degrees

$z=\dfrac{10-15.45}{13.70}=-0.397810218\approx-0.40$

The P-value : $P(-0.76$

$=0.3445783-0.2236273=0.120951\approx0.1210$

In percent , $0.1210\times100=12.10\%$

Hence, the percentage of days had a low temperature between 5 degrees and 10 degrees = 12.10%
