First we need to find out how many numbers are less than 9.
There are 8 numbers less than 9.
So, to convert this into a percent, we need to put favorable outcomes over possible outcomes.

Favorable outcomes
-----------------------------
Possible outcomes

The possible outcomes is 12, because that is the total number of outcome you can possibly have.

The favorable outcomes is 8, because that is how many number that are less than 9.

So, that gives us this...

8
--
12

Then we can divide to get;
0.6666666
Then we can convert this decimal into a percent by moving the decimal point over 2 times and then rounding.

To get a final answer of 67%.
Hope this helps.

In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time

Nikitich [7]

88 % students of the class hand in their projects on time

Solution:

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

To find: percent of the class hand in their projects on time

$\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100$

Substituting the values, we get

$\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88$

Thus 88 % students of the class hand in their projects on time

Find the slope between the following points, show all work. (-1, -8) and (-3, -2)

Hatshy [7]

How you get this answer is do delta y over delta x so that means take your y values (-8 and -2) and subtract and do the same thing with your x values so subtract (-1 and -3) so then youll end up with: -6 over 2, next steo is to see if you can simplify, and in this case you can so divide 2 and 6 so youll end up with -3 as your final answer. (this should be written in fraction form)
