It takes jill 2 hours to run 14.5 miles. At this rate how far could she run in 3 hours?

grin007 [14]

Answer:

She can travel 21.75 miles in 3 hours.

Step-by-step explanation:

Firstly, you have to find out how many miles can Jill travel in 1 hour. So you divide it by 2 :

$2hr = 14.5miles$

$1hr \: = 14.5 \div 2 \\ 1hr = 7.25miles$

We have found out that she can travel 7.25 miles per hour. Next wr have to multiply it by 3 as the question says how far she run in 3 hours :

$1hr = 7.25miles$

$3hr = 7.25 \times 3 \\ 3hr = 21.75miles$

if the measure of <BEC is (2x+3)° and x=30, which expression could represent the measure of <AED?

Maurinko [17]

Answer:

The answer is 3x-27

Step-by-step explanation:

If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.

A game involves rolling a number cube. You get one point if you roll an even number and negative one point if you roll an odd nu

Burka [1]

Answer: The sample space is {1, 2, 3, 4, 5, 6}.

The expected value for the game is 0.

The game is fair because the expected value is equal to 0.

Step-by-step explanation:

For rolling a dice the sample space = {1, 2, 3, 4, 5, 6}

As there are equal number of odd numbers as well as even numbers and we get one point if we roll an even number and negative one point if you roll an odd number, therefore, the expected value = 0

Therefore, the game is fair because the expected value is equal to 0.
