An inequality is when you compare two things and one is greater than the other, while for an equation both sides of the equation are balanced. You would use an inequality like when you need to find the minimum you need to achieve for something, like how much you have to save. Ex. Y is greater than or eqaul to 5x + 8 for your trying to pay off rent. You need a payment of 8 dollars at the start. After that, you need to pay 5 dollars a day. Y represents how much you have to earn in order to have enough, or more than enough money to pay of rent.

Angle JKL is 54 degrees. What is the measure of angle MKL? *
hoa [83]

Answer:

MKL = 36°

Step-by-step explanation:

(3x + 6) + (6x + 12) = 54°

3x + 6x + 6 + 12 = 54

9x + 18 = 54

9x = 54 - 18

9x = 36

x = 36/9

x = 4

MKL = 6x + 12

MKL = 6(4) + 12

MKL = 24 + 12

MKL = 36°

The average and standard deviation of a measurement is 15.0 ± 5.0. if 100 students measured the value, how many would you expect
AURORKA [14]

Solution: We are given:

\mu=15, \sigma=5

Using the empirical rule, we have:

\mu \pm \sigma covers 68% of data.

Also the percentage of values below mean = Percentage of values above mean = 50%

Now, let's find the z score for x=20

z=\frac{20-15}{5}=1

Therefore, the percentage of values greater than 1 standard deviation above mean 50\% - \frac{68\%}{2} =50\%-34\%=16%

Expected number of students = 16% of 100 = 16
