Hiro bought a small carton of milk at lunch.
Bogdan [553]

Answer

If I understand the problem correctly, It would be 95 inches squared although the number I got was 95.74, which would actually round to 96. What I think it is asking for is the surface area of the milk carton.

Bottom:

<em>length * width</em>

3 * 3 = 9

Rectangular Sides:

One side would be the length or width (which both equal 3) times the height (6.5), and there are 4 total sides.

<em>number of sides(length or width * height)</em>

4(3 * 6.5) = 4(19.5) = 78

Triangular Sides:

One side would be \frac{1}{2} * base (3) times height (1.5), and there are 2 triangular sides.

<em>2(1/2(base * height))</em>

2(1/2(3 * 1.5)) = 3 * 1.5 <em>(The 2 and the 1/2 cancel each other out)</em> = 4.5

The Roof-shaped Top Surfaces:

These are rectangles that you the width is equal to the length of the rectangular prism, and the length is equal to the one side of the triangle. You can find that length by using the Pythagorean theorem (\sqrt{1.5^2 + 1.5^2}) which 1.5 is half of the base and the other 1.5 is the height. There are 2 of these rectangles making the final equation 2\sqrt{1.5^2+1.5^2} ≈ 4.24.

Now, add up each of the values:

9 + 78 + 4.5 + 4.24 = 95.74.

A student decided to run a simulation of rolling an even number with a single die. Use the simulated results from 20 attempts to
jenyasd209 [6]

Answer: Choice A

The simulated probability probability is 0.450, which is less than the theoretical probability

=========================================

Explanation:

In the given list of numbers shown, count how many times an even number comes up. In this case, the even numbers that show up are, in this order: 2, 6, 6, 4, 4, 6, 2, 2, 6

There are 9 even numbers in the list of 20 total. So the simulated probability of getting an even number is 9/20 = 0.450 which is a 45% chance. This is based on this current data set.

If we assumed that each side of the die was equally likely to be landed on, then there are three even numbers (2,4,6) out of six total (1 through 6). So the theoretical probability of getting an even number is 3/6 = 1/2 = 0.500

Comparing 0.450 to 0.500, we see that 0.450 is smaller. You can think of it as like saying "450 is smaller than 500".
