mean = (sum of values) / (number of values)

we know mean is 13 and we are given 8 values. The ninth value is the missing x:

13 = ((sum of 8 values) + x)/9

13 = (12+10+15+12+13+15+11+15+x)/9

13*9 = 103+x

x = 14

The missing value is 14. There are 14 pillows in the last box.

The sum of three numbers is 18. If every number is a prime number, what are the three numbers?
sleet_krkn [62]
The three numbers are 2, 5, and 11.

The sum of 3 numbers is 18.        2 + 5 + 11 = 18

Since the problem states that every number is a prime number, then the number must be a natural number greater than 1 that has no positive divisors other than 1 and itself.

2 / 1 = 2  OR  2 / 2 = 1  These numbers are prime numbers because their divisors
5 / 1 = 5  OR  5 / 5 = 1            are 1 and itself.
11/1 = 11 OR 11/11 = 1

Solve these compound interest problems and round your answer to the nearest 100th.
MatroZZZ [7]

Answer:

$2,226.96

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>n = number of times compounded annually </em>

<em>t = time </em>

<em />

First, change 10% into its decimal form:

10% -> \frac{10}{100} -> 0.1

Now lets plug in the values into the equation:

A=500(1+\frac{0.1}{12})^{15(12)}

A=2,226.96

The final amount after 15 years is $2,226.96

Hey!


1 car is $3.83.

3 cars is $3.83 × 3


3.83 × 3 = 11.49


Shipping fee is $4.55. Add that to the price of the 3 cars


11.49 + 4.55 = 16.04


The girls share the cost equally. Divide by 2


16.04 ÷ 2 = 8.02
