2r2 + 3s3 − r2 + 4t2 − r2 if r = −2, s = −3, and t = 5

Use the Leading Coefficient Test to determine the end behavior of the polynomial function . f(x) = 5x ^ 4 - 2x ^ 2

Alexxx [7]

Answer:

Step-by-step explanation:

hello :

f(x) = 5x ^ 4 - 2x ^ 2

f(x) = 5x ^ 4+0x^3 - 2x ^ 2+0x+0

the Coefficient are : 5 , 0 , -2 ,0 , 0

Using the following image, apply what you have learned about linear pairs and solve for

posledela

It would be 4x+76 = 180 in that order in the boxes. You would add 1 to 75 which got 76. Then you would subtract 76 from 180 and get 104 and then divide that by 4 and you would get 26. So x is 26

Ethan needs to save at least $500 to purchase a new dirt bike. So far, he has saved $175. If he hopes to use two-fifths of his n

IRISSAK [1]

Answer:

$812.5

Step-by-step explanation:

Given: Ethan need to save at least $500.

He has saved so far $175

Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Lets assume Ethan´s paycheck amount be "x"

First finding the remaining amount to be covered.

Remaining amount= $\$ 500 - \$ 175= \$ 325$

∴ The remaining amount to be covered is $325.

As given, Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Now, using the inequality to find the amount of paycheck.

⇒ $x\times \frac{2}{5} \geq \$ 325$

multiplying both side by 5

⇒ $x\times 2\geq 325\times 5$

divinding both side 2

⇒ $x\geq \frac{1625}{2}$

∴ $x\geq \$ 812.5$

Hence, Ethan must make at least $812.5 in his paycheck to cover his remaining anount to buy dirt bike.

The amount of soft drink in a bottle is a Normal random variable. Suppose that in 7% of the bottles containing this soft drink t

WITCHER [35]

Answer:

The mean is 15.93 ounces and the standard deviation is 0.29 ounces.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

7% of the bottles containing this soft drink there are less than 15.5 ounces

This means that when X = 15.5, Z has a pvalue of 0.07. So when X = 15.5, Z = -1.475.

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

$-1.475 = \frac{15.5 - \mu}{\sigma}$
