Answer:
B. 88.5
Step-by-step explanation:
first we add all the numbers :
(79 +80 +92 +92 +81 +100 +88 +98 +71 + 100+91+90) over 12
= 1062 over 12
= 88.5
[why over 12? because there's 12 numbers]
Answer:
the correct answer is C. 45
Step-by-step explanation:
so 1/5 means there are 5 peice to make a whole...
so if you cut an apple into 5 parts, each slice of that apple is 1/5
so if you cut 9 apples into 5 slices its just multiplication...
5*9=45
**for my visual learners** in the parenthesis are groups of 5 sticks
( ///// ) **those are your apple slices** **now just do that exactly 9 times**
( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// ) ( ///// )
5 10 15 20 25 30 35 40 45

2 3/8 - 1/4 = 2 1/8 x 1/8 = 17/64.
To do this, you first need to do the problem in the (). You have to turn 1/4 with a denominator of eight, so the fraction becomes 2/8. 2 3/8 - 2/8 = 2 1/8. Now we have to turn 2 1/8 into an improper fraction by doing whole number x denominator + numerator. 17/8 x 1/8 = 17/64.
The Z-score is calculated by the formula below
Step 2: Substitute the given parameters in the formula
Hence, the z-score of a person who scored 145 on the exam is -0.5
The percent off the store should display is 27.0%
- The initial percent off given to Matt = 20%
- The additional percent off given to Matt = 7%
The percent off the store should display is the total percent off given to their product. That is, the addition of the first and second percent off.
The total percent off the store gave to Matt is calculated as;
= 20% + 7%
= 27%
To the nearest tenth of a percent = 27.0%
Thus, the percent off the store should display is 27.0%
