Answer:

a) 320 students

b) 25 students

Step-by-step explanation:

Number of 18-years old in the survey:

(We add all  frequency points for each line)

0 + 30 + 20 + 60 + 70 + 40 + 60 + 40 + 0 = 320 students

Number of 18 year old spending between 25 and 35 minutes: 40 + 65 = 105

Number of 12 year old spending between 25 and 35 minutes: 30 + 50 = 80

105 - 80 = 25 students

What is the value of x?<br>x=____​
Setler79 [48]
The answer is x = 6

To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2

In this problem a = x b = 8 and c = 10

You would then square these numbers
x^2 + 64 = 100

Next, you would subtract 64 from both sides.

x^2 = 36

All that’s left is the find the square root, which is x = 6.

So, therefore, you’re answer is x = 6
