How do you find the lateral and surface area of a rectangular prism

Mathematics

Blizzard [7]3 years ago

Answer:

When a prism has its bases facing up and down, the lateral area is the area of the vertical faces. (For a rectangular prism, any pair of opposite faces can be bases.) The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism

Step-by-step explanation:

To find the lateral surface area, we will find half of the perimeter of the base and multiply it by the slant height of the side triangles. Each triangle has a slant height.

What number is multiple by itself the result is 3 6/25 find the number

Alinara [238K]

Answer:

9/5

Step-by-step explanation:

Create an Equation: x^2 = 3 + 6/25
Simplify the Right Side: 3 + 6/25 = 75/25 + 6/25 = 81/25
Substitute the Values back into the Equation: x^2 = 81/25
Solve for x by taking the Square Root of Both Sides: x = √81/25
Simplify: x = √81/√25 = 9/5

Answer:

The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 28$

The alternate hypotesis is:

$H_{1} < 28$

The test statistic is:

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

A recent survey of 50 executives who were laid off during a recent recession revealed it took a mean of 26 weeks for them to find another position.

This means that $n = 50, X = 26$

Assume the population standard deviation is 6.2 weeks.

This means that $\sigma = 6.2$

Does the data provide sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

We have to find the pvalue of Z, looking at the z-table, when $\mu = 28$ . It if is lower than 0.05, it provides evidence.

$z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{26 - 28}{\frac{6.2}{\sqrt{50}}}$

$z = -2.28$

$z = -2.28$ has a pvalue of 0.0113 < 0.05.

The pvalue of 0.0113 < 0.05 means that there is sufficient evidence to conclude that the mean time to find another position is less than 28 weeks at the 5% level of significance

How can you multiply a mixed number

Grace [21]

Turn it into a improper fraction and then multiply both the numerator and denominator together!
So like 1 1/2 x 2 1/2
Turn that into improper fractions and get 3/2x5/2
then you get 15/2 which is 7 1/2

If you apply the changes below to the linear parent function, f(x) = x, what is the equation fo the new function?

ad-work [718]

Answer:

Step-by-step explanation:

For a function in the form f(x) = x, we can say:

the function f(x) = ax is a vertical stretch if a>1 and compress if 0<a<1
the function -f(x) is the original, flipped over x-axis

keeping the 2 rules in mind, we can say that

vertical stretch by a factor of 3 would make it f(x) = 3x

Then

flip over x-axis would make it f(x) = -3x
