Answer:

10 boys

Step-by-step explanation:

if the ratio of boys to girls is 2:1, and 5 girls were there, then 1=5.

since 1=5, we can multiply it by the other number in the ratio: 2.

or you can add 5+5 because there are 2 fives

2x5=10. . therefore, 2=10 so there would be 10 boys.

hope this helps!

There was 10 boys at the movie.

2:1 ratio means there was twice as much boys as girls, 5 x 10 = 10

10 boys is twice as much as 5 girls.

Ryan is correct, the mean is about 8.1.

To find the mean, you have to add up all the values, then divide by the total amount.

For Sample A:
60 x 6 + 90 x 7 + 145 x 8 + 150 x 9 + 55 x 10 = 4050

If you add up all the adults, you have 500.

Dividing 4050 by 500 = 8.1

Sample B will produce a very similar result.

Answer:

$\frac{11}{25}$

Step-by-step explanation:

In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...

$\frac{33}{75}$ or 0.44
