Answer:

I got 2,717.45

Step-by-step explanation:

I did 2,363 × 15% = 354.45

then 2,363 + 354.45 = 2,717.45

Answer:

$2,780

Step-by-step explanation:

Let the original price be P

2,363 =P - 15% x P

2,363 =P - 15/100 x P

2,363 = P - 0.15P

2,363 = 0.85P

Divide both sides by 0.85

2,363/0.85 = 0.85P/0.85

2,780 = P

I hope this helps.

Solve for x 12x/5 a.x=-71/2 b. x=71/2 c. x= 43 1/5

babunello [35]

Answer:

x = - 12 6/7

Step-by-step explanation:

x - 12x/5= 18

Get a common denominator on the left

5/5 x -12/5x = 18

Subtract

-7/5 x = 18

Multiply each side by -5/7 to isolate x

-5/7 *-7/5 x = -5/7 *18

x = -5*18/7

x = -90/7

Changing this to a mixed number

7 goes into 90 1 2 times with 6 left over

x = - 12 6/7

A statistics teacher started class one day by drawing the names of 10 students out of a hat and asked them to do as many pushups

mash [69]

Using the t-distribution, we have that the 95% confidence interval for the true mean number of pushups that can be done is (9, 21).

For this problem, we have the <u>standard deviation for the sample</u>, thus, the t-distribution is used.

The sample mean is of 15, thus $\overline{x} = 15$ .
The sample standard deviation is of 9, thus $s = 9$ .
The sample size is of 10, thus $n = 10$ .

First, we find the number of degrees of freedom, which is the one less than the sample size, thus df = 9.

Then, looking at the t-table or using a calculator, we find the critical value for a 95% confidence interval, with 9 df, thus t = 2.2622.

The margin of error is of:

$M = t\frac{s}{n}$

Then:

$M = 2.2622\frac{9}{\sqrt{10}} = 6$

The confidence interval is:

$\overline{x} \pm M$

Then

$\overline{x} - M = 15 - 6 = 9$

$\overline{x} + M = 15 + 6 = 21$

The confidence interval is (9, 21).
