The first thing we must do is find the percentage that has traveled outside of the United States.
For this, we make the following rule of three:
30 ---------> 100%
9 -----------> x
We clear the value of x:
x = (9/30) * (100)
x = 30%
Then, for 120 sixth graders in the school we have:
(0.30) * (120) = 36
Answer:
36 students have traveled outside of the united states
G(-7, 4)
(x + 10, y - 6) = (-7 + 10, 4 - 6)
(x + 10, y - 6) = G'o(3, -2)
b) how many houses are in your town?
c) what percent of long grove high school
students like pizza?
d) what is the average temperature in january?
Answer:
D. 48
Step-by-step explanation:
Let's first find the probability that in the first 40 trials, exactly two of the coins are heads.
We know that there were 16 such outcomes of 2 heads and 1 tail, and there was a total of 40 possible outcomes. So our probability is:
16 / 40 = 4 / 10 = 2/5
We can assume that the probability that in the next 120 trials, about 2/5 of the outcomes will also be 2 heads and 1 tail. So, we multiply 2/5 by 120 to figure out that exact number:
(2/5) * 120 = 240/5 = 48
The answer is thus D.
