Answer:

P(x < 92) is 0.16

Step-by-step explanation:

We are given that the normal distribution has a mean of 98 and a standard deviation of 6.

Mean =\mu = 98

Standard deviation = \sigma = 6

We are supposed to find  P(x < 92)

Formula : Z=\frac{x-\mu}{\sigma}

Z=\frac{92-98}{6}

Z=-1

Refer the z table for p value

So,p value = 0.1587

So, P(x < 92) is 0.16

Option A is true

Hence  P(x < 92) is 0.16

Find the sum. Write your answer in simplest form. 3/7 + 2/3​
Delicious77 [7]

Answer:

1 2/21

Step-by-step explanation:

We start out with:

3/7 + 2/3

In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:

3/21 + 2/21

But what about the numerators? You do the same thing as before (multiplying by the other's denominator).  Now we have:

9/21 + 14/21

We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:

1 2/21!

Ava buys a used car that costs $6,700.00. She trades in her old car for $3,995.00. How much does she pay in cash for the car?
irakobra [83]
So this statement is caused for subtracting. So we have to subtract 6,700.00 from 3,995.00 and the answer would be 2705
Hope this helps :)

Select the correct answer.
Katen [24]

Answer:

A.  v= $3,995.72 - $1,838.03

Step-by-step explanation:

Given:

fixed expenses: $1,838.03

total expenses: $3,995.72

We need to find the amount of Variable expense (v).

Now We know that;

Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.

framing in equation form we get;

Variable expense (v) = total expenses - fixed expenses.

Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69

Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03
