Answer:
There is no difference. Because the mean of Ari's tests equals his median score of his six tests. mean = 84% median = 84%
Step-by-step explanation:
88%, 73%, 97%, 76%, 90%, 80%
organize by low to high
73%, 76%, 80%, 88%, 90%, 97%
The median here is (80 + 88)/2 = 84%
let us find the mean
mean = [73% + 76% + 80% + 88% + 90% + 97% ]/6
mean = 504/6 = 84%
There is no difference. Because the mean of Ari's tests equals his median score of his six tests. mean = 84% median = 84%
The phrases 3 to the 4th power and 3 to the power of 4 are equivalent to the algebraic operations 4 × 4 × 4 × 4 and 44.
Answer:
Each CD cost $20.50
Step-by-step explanation:
You would divide the cost of the DVDs by 4: 164÷4=41
Now the CDs are half the cost of the DVDs so you would divide 41 by 2: 41÷2=20.50
Your answer would be $20.50
Answer:
2 1/3
Step-by-step explanation:
Fractions are added using a common denominator.
1 5/6 + 1/2
= 1 5/6 + 3/6
= 1 8/6
= 1 + (1 2/6)
And they are reduced by removing a common factor from numerator and denominator.
= 1 + 1 1/3
= 2 1/3
