Answer:

q1=11

q3= 33

Step-by-step explanation:

The data set has 44 number of students. The first quartile is 25 %  of the numbers in the data set . So

25 % of 44 = 25/100 * 44= 0.25 *44 = 11

So the first quartile lies at 11.

Similarly the third quartile lies at the 75 % of the numbers of the data set . So

75 % of 44 = 75/100 * 44= 0.75 *44 = 33

So the third quartile lies at 33.

I Need help plz help me i Sony understand

A. 2, 200, 2000  

This is multiplying the number by 10 each time. In other words, just adding an extra zero to the end of it. 

b. 340, 0.034 

This one is moving the decimal place forward two places. 10^-2, so removing two zeros from the end of it until eventually you reach decimals and have to move the decimal forward twice, which is essentially what you're doing here.

c. 85700, 857, 0.857

In this one, you remove one zero from the end. You move the decimal forward once when you reach the decimals. This would be 10^-1

d. 444000, 4440000, 44400000

In this one, you multiply each one by 10. Add on a zero to each one.

e. 0.095, 9500000, 950000000

You multiply this one by 10^2, so the number increases.

Help picture below problem 12
inysia [295]

Answer:

124°

Step-by-step explanation:

Not the best at explaining but should be equal to 180 straight across. You have to find the missing angle. You know the right angle is 90° so you will add 34° to get 124°. 180-124 will get you 56°. Straught across you have the angle that you are trying to find which is 124° because 180-56 is 124.
