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

What is the slope of a trend line that passes through the points (–3, 3) and (18, 26)? StartFraction 15 Over 29 EndFraction Star

Alik [6]

Answer:

23/21

Step-by-step explanation:

The slope is computed from ...

m = (y2 -y1)/(x2 -x1)

For the given points, the slope is ...

m = (26 -3)/(18-(-3)) = 23/21

The slope of the trend line is 23/21.
