Answer:

x=2

Step-by-step explanation:

7(5+2x)+x=65

35+14x+x=65

35+15x=65

15x=65-35

15x=30/15

x=2

Answer:

x=2

Step-by-step explanation:

7×5=35

7×2x=14x+=65

so the equation would be

35+14x+x=65

add the variables together so:

35+15x=65

subtract 35 from 65 which makes it 30 so:

15x=30

now divide both sides by 15

which makes the anwer x=2

What is the percent change from 1800 to 1926

Crank

The percentage change is 6.54%
You have to divide 1800÷1926, then multiply by 100 and you'd get 93.46, then subtract 100-93.46 which equals 6.54% :)

The playing life of a Sunshine radio is normally distributed with mean LaTeX: \muμ = 600 hours and standard deviation LaTeX: \si

Hitman42 [59]

Answer:

The probability that a radio selected at random will last from 600 to 700 hours is 0.3413

Step-by-step explanation:

The playing life of a Sunshine radio is normally distributed

Mean = $\mu = 600 hours$

Standard deviation = $\sigma = 100 hours$

We are supposed to find the probability that a radio selected at random will last from 600 to 700 hours i.e.P(600<x<700)

Formula: $Z= \frac{x-\mu}{\sigma}$

At x = 600

$Z= \frac{600-600}{100}$

Z=0

$P(X$

At x = 700

$Z= \frac{700-600}{100}$

Z=1

$P(X$

$P(600$

Hence the probability that a radio selected at random will last from 600 to 700 hours is 0.3413
