6, 12, 18, 24, 30, 36, 42

7, 14, 21, 28, 35, 42

The least common multiple is 42, which means every 42 days they will golf on the same day.

Rick buys 3 CDs and 5 video games. The cost of one video game is $12.00 more than the cost of one CD. If Rick spends $164.00, wh

Dmitry [639]

Step-by-step explanation:

x = price per video game

y = price per CD

164 = 5x + 3y

and then we know

x = y + 12

now we can use this as substitute in the first equation :

164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60

104 = 8y

y = $13

x = y + 12 = 13 + 12 = $25

so, each CD costs $13.

The Census Bureau reports that 82% of Americans over the age of 25 are high school graduates. A survey of randomly selected resi

Answer:

Mean = 910.2

Standard deviation = 12.8

Step-by-step explanation:

82% over the age of 25 are high school graduates.

A survey randomly selected students of certain country included 1110 who were over the age of 25 and 871 of them were high school.

n = 1110

p = 82% = 0.82

q = 1 - 0. 82

q = 0.18

Mean = np

= 1110*0.82

= 910.2

Standard deviation = √npq

= √ 1110*0.82*0.18

=√163.836

= 12.8

Use three different values of n to demonstrate that 2n + 3n is equivalent to 5n.

GarryVolchara [31]

n can be 0 so 2(0) +3(0) = 0 now lets go up by one so 2(1) +3(1)= 5 now we will go up another number so lets go for 2(2)= 10 so we figured out that 2(1) +3(1) is 5 so n equals 1

Larre used the visual model to show what fraction of an hour he spent outside. He wants to break the next hour into two times as

klasskru [66]

First, identify what fracion of an hour Larre spent outside using the model.

Since the square is divided in 4 equal parts, then the denominator of the fraction that Larre wants to represent is 4.

On the other hand, since 2 of those 4 parts are colored, then the numerator of the fraction that Larre wants to represent is 2.

Then, the fraction represented by the visual model is:

$\frac{2}{4}$

To find the answer, find an equivalent fraction by multiplying both the numerator and the denominator by 2:

$\frac{2}{4}=\frac{2\times2}{4\times2}=\frac{4}{8}$

Therefore, an equivalent fraction that can be made by multiplying the numerator and denominator by 2, is:

$\frac{4}{8}$

The correct choice is option C) 4/8.
