Can someone help me really quickly and have a explainton for as well

What happens to the value of the expression n+15 as n decreases?

Degger [83]

Answer: It decreases

Step-by-step explanation:

Theoretically, let's say n = 15

15 + 15 = 30

Now, let's use 14, because 14<15

14 + 15 = 29

So, the value decreases as n decreases

What is the ratio of the volume of Cylinder A to the volume of Cylinder B? if cylinder a has the height of 4 and radius of 3 and

Amanda [17]

Answer:

3/4

Step-by-step explanation:

Cylinder A

V = πr^2h

V = π(3)^2(4)

V = 36π

Cylinder B

V = π(4)^2(3)

V = 48π

36π/48π

Determine the product, h(x), of the linear and quadratic factors.

Airida [17]

Answer:

$h(x)=x^3-17x-4$

Step-by-step explanation:

Given $f(x)=x^2 - 4x -1\ and\ g(x)=x+4\\$

$h(x)=f(x)\times g(x)$

$(x^2-4x-1)(x+4)\ \ \\Distribute\ parenthesis\\=x^2x+x^2\times \:4+\left(-4x\right)x+\left(-4x\right)\times \:4+\left(-1\right)x+\left(-1\right)\times \:4$

Apply minus-plus rules

$+(-a)=-a$

$=x^2x+4x^2-4x(x)-4\times\:4x-1\times\:x-1\times\:4$

$\\Simplify\\=x^3+4x^2-4x^2-16x-x-4\\=x^3-16x-x-4\\=x^3-17x-4$

$h(x)=x^3-17x-4$

A woman is 5 1⁄7 inches taller than her daughter. The woman is 66 1⁄7 inches tall. How tall is her daughter?

rodikova [14]

Her daughter's length would be 61 inches because 66 1/7 - 5 1/7 = 61 in.

Laundry detergent boxes are filled according to an approximately Normal distribution with mean 34.15 ounces and standard deviati

Leno4ka [110]

Using the normal distribution, it is found that there is a 0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 34.15, \sigma = 0.1$ .

The probability a randomly selected box has less than the 34 ounces of advertised weight is the <u>p-value of Z when X = 34</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{34 - 34.15}{0.1}$

Z = -1.5

Z = -1.5 has a p-value of 0.0668.

0.0668 = 6.68% probability a randomly selected box has less than the 34 ounces of advertised weight.
