Answer:

\Large \boxed{- \frac{1}{5}}

Step-by-step explanation:

\displaystyle \sqrt[3]{-\frac{1}{125} }

Distribute the cube root to the numerator and denominator.

\displaystyle -\frac{\sqrt[3]{1} }{\sqrt[3]{125} }

Solve for the cube root.

\displaystyle - \frac{1}{5}

A.
The second and first quadrant, because the hour and temperatures are unlikely to be negative numbers. All positive numbers for both X and Y values are in the second quadrant. If the hour is before noon, then the X value will venture into quadrant one. The diagram shows the quadrants in a graph.

B. For both the time and the temperature to be negative, and in quadrant four, you would have to be located in possibly Alaska or northern Canada. In such locations colder areas would be more likely to have negative temperatures and at times before 12.

One number is 3 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 215,
Aleksandr [31]

Answer:

23, 69 and 123

Step-by-step explanation:

let the first number be x then the second number is 3x ( 3 times the first) and the third number is x + 100 ( 100 more than the first number)

The sum of the three numbers is

x + 3x + x + 100 = 215

5x + 100 = 215 ( subtract 100 from both sides )

5x = 115 ( divide both sides by 5 )

x = 23

The 3 numbers are

x = 23, 3x = 3 × 23 = 69 and x + 100 = 23 + 100 = 123

An operation manager at an electronics company wants to test their amplifiers. The design engineer claims they have a mean outpu
andreyandreev [35.5K]

Answer:

The probability that the mean amplifier output would be greater than 364.8 watts in a sample of 52 amplifiers is 0.3156

Step-by-step explanation:

Mean output of amplifiers = 364

Standard deviation = \sigma = 12

We have to find the probability that the mean output for 52 randomly selected amplifiers will be greater than 364.8. Since the population is Normally Distributed and we know the value of population standard deviation, we will use the z-distribution to solve this problem.

We will convert 364.8 to its equivalent z-score and then finding the desired probability from the z-table. The formula to calculate the z-score is:

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }

x=364.8 converted to z score for a sample size of n= 52 will be:

z=\frac{364.8-364}{\frac{12}{\sqrt{52} } }=0.48

This means, the probability that the output is greater than 364.8 is equivalent to probability of z score being greater than 0.48.

i.e.

P( X > 364.8 ) = P( z > 0.48 )

From the z-table:

P( z > 0.48) = 1 - P(z < 0.48)

= 1 - 0.6844

= 0.3156

Since, P( X > 364.8 ) = P( z > 0.48 ), we can conclude that:

The probability that the mean amplifier output would be greater than 364.8 watts in a sample of 52 amplifiers is 0.3156
