igomit [66]

y = 12x represents the gallons of paint used in x hours.

Step-by-step explanation:

CJ uses 3 gallons of paint in 15 minutes,

15 minutes = 3 gallons

1 minutes = $\frac{3}{15} = \frac{1}{5} \ gallons\\$

1 hour = 60 minutes

Gallons of paint used in 1 hour;

1 hour = $\frac{1}{5}*60=12\ gallons$

CJ uses 12 gallons of paint in 1 hour.

For x hours = 12*x = 12x

Gallons of paints used = y

y = 12x represents the gallons of paint used in x hours.

Answer:

FV(n)=42,000(1.04)^n

Step-by-step explanation:

FV=PV(1+r/n)^nt

Where

FV=future value

PV=present value

r=interest rate

n=number of periods

t=time (years)

PV=42,000

r=4%=0.04

n=1

t=n

FV(n)=p(1+r/n)^nt

=42,000(1+0.04/1)^1*n

=420000(1+0.04)^n

=42,000(1.04)^n

FV(n)=42,000(1.04)^n

Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches. What is

NNADVOKAT [17]

Answer:

The probability that the man is greater than 74 inches is 0.1587

Step-by-step explanation:

The required probability is found by evaluating the area under the corresponding distribution curve for the corresponding values

The standard normal variate factor (Z) is given by

$Z=\frac{x-\bar {X}}{\sigma }$

where

$\bar{x}$ is mean of the data

$\sigma$ is the standard deviation of the data

Thus corresponding to x = 74 the Z factor equals

$Z=\frac{74-70}{4}=1$

Using the standard normal distribution table corresponding to mean of 70 and deviation of 4 the area under the curve corresponding to Z = 1 equals

0.1587
