Answer: 14 1/8

Step-by-step explanation: To add mixed numbers, first add the fractions. In this case, we have two fractions \frac{1}{2} and \frac{5}{8} and these fractions have unlike denominators. We need to find a common denominator for both of these fractions to be able to add.

<u>Least Common Denominator:</u>

\frac{1}{2} = \frac{4}{8}

\frac{5}{8} = \frac{5}{8}

12 4/8 + 1 5/8 = 13 9/8

Notice that 9/8 is an improper fraction so we can change it to a mixed number.

9/8 = 1 1/8

13 + 1 and 1/8 = 14 1/8

a line with a slope of 1 passes through the point (5,10). what is the equation in this slope-intercept form?
patriot [66]

Answer:

y=x+5

Step-by-step explanation:

So first you need to plug everything into the point-slope formula which is

y-y1=m(x-x1)

m being the slope and y1 and x1 being the point (5,10)

So once you plug it in it should look like this: y-10=1(x-5)

Now you solve it

First you need to distribute 1 in 1(x-5) which is (x-5)

Now you have y-10=x-5

Then you add 10 to both sides which is y=x+5

Your answer is y=x+5

Christine performed the following experiment 20 times using a book that contains 462 pages.
wel

Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem:

  • The experiment was made 20 times.
  • Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.

Then:

p = \frac{6}{20} = 0.3

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.
