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 solution to the system shown below y=2x-1. Y=2x+3 A (0,0). B(1,-3) C(-1,3). D no solution
Setler [38]
We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2

we know that
</span>If two lines are parallel<span>, then they will never intersect
</span><span>
therefore
the answer is the option
</span><span>D no solution</span><span>

The temperature on a summer afternoon is 76°F. Define a variable and write an expression to find the temperature after it change
Afina-wow [57]
Letting "c" be the value of the temperature change, looking at the choices, the nearest answer would be C. " 76 + c; 76 + (–8) = 68; 68°F ".

76 is the base or current temperature, then c would be the change in temperature experience. Since a decrease of 8 degrees is to be experienced, it is denoted by the negative symbol on 8.
