Sharon rented a car for a base price of $200 and has to pay $13 for each day she drives. If her total bill is $252, how many day

s did she drive the rental car? Write a function rule to represent the total cost of renting a car as a function of the miles driven. Be sure to define your variables. b) Use your function rule to set up an equation to find the total miles driven, if Sharon was charged $252. c) Solve your equation from part (b) and determine how many miles were driven.

Answer:

<h2>x =  -  \frac{19}{4}</h2>

Option B is the correct option.

Step-by-step explanation:

-  \frac{1}{2}  + x =  -  \frac{21}{4}

Move constant to R.H.S and change its sign:

x =  -  \frac{21}{4}  +  \frac{1}{2}

Take the L.C.M

x =  \frac{ - 21 + 1  \times 2}{4}

x =  \frac{ - 21 + 2}{4}

Calculate

x =  -  \frac{19}{4}

Hope this helps...

Good luck on your assignment..

I'm confused on simplifying radicals.​
lakkis [162]

Answer: 4 or \sqrt{4 * 4}

To find the square root of a number, remember that there will be two factors that are the same that will give you the product.

Lets start from 1:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.

4 and 4 are the same numbers.

Therefore, \sqrt{16} = 4

It can also be written as \sqrt{4 * 4}

In a sample of 1000 cases, the mean of a certain test is 14 and the standard deviation is 2.5. Assume the distribution to be nor
Maslowich

Answer:

The top 20% of the students will score at least 2.1 points above the mean.

Step-by-step explanation:

When the distribution is normal, we use 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.

The mean of a certain test is 14 and the standard deviation is 2.5.

This means that \mu = 14, \sigma = 2.5

The top 20% of the students will score how many points above the mean

Their score is the 100 - 20 = 80th percentile, which is X when Z has a pvalue of 0.8. So X when Z = 0.84.

Their score is:

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

0.84 = \frac{X - 14}{2.5}

X - 14 = 0.84*2.5

X = 16.1

16.1 - 14 = 2.1

The top 20% of the students will score at least 2.1 points above the mean.
