We’ll use probability to answer this question.

Probability: Number of even numbers / All numbers added together.

Odd numbers: 1,3,7
Even numbers: 4

All numbers added together (amount of numbers not the numbers itself!) = 4

Amount of even numbers = 1

Probability of getting an even number is 1/4

Answer: Yes she is correct, the probability of getting an even number is 1/4.

Once you have the points they make a 3-4-5 triangle. The two legs are 3 and 4, so the hypotenuse has to be 5. Or you could use the pythagorean theorem a² + b² = c² 3² + 4² = c² 25 = c² c = 5

A tepee is designed to have a diameter of 10 ft and a volume of 393 ft. At
Citrus2011 [14]

Answer:

15 ft.

Step-by-step explanation:

The tepee is a cone and its volume

= 1/3 pi r^2 h   where r = radius and h = height.

The radius r = 1/2 * 10 = 5 ft.

So we have the equation:

393 = 1/3*3.14* 5^2 * h

h = 393 / (1/3*3.14*25)

=  15.02 ft.
