Answer:
9.5/8 = 1.1875
Step-by-step explanation:
4^(3m-1) • 32^(2m-3) = 4
4^(3m-1) • (4^2.5)^(2m-3) = 4
Law of exponents
3m-1 + 2.5(2m-3) = 1
3m - 1 + 5m - 7.5 = 1
8m = 1 + 1 + 7.5
8m = 9.5
m = 9.5/8
Answer:
3 feet by 7 feet
Step-by-step explanation:
perimeter = 20 feet
area = 21 feet²
If the desk is a rectangle:
perimeter = 2l + 2w = 2 (l+w) = 20
2 (l+w) = 20 , divide both sides by 2
l+w = 10
area = l · w = 21
What numbers we know that have sum as 10 and their product as 21?
l + w = 10
l · w = 21
factors of 21 are 1,3,7
3+7 = 10
3 ·7 = 21
The dimensions of the desk could be 3 feet by 7 feet.
Answer:
Tree diagrams display all the possible outcomes of an event. Each branch in a tree diagram represents a possible outcome. Tree diagrams can be used to find the number of possible outcomes and calculate the probability of possible outcomes.
Step-by-step explanation:
Answer:
Median.
Step-by-step explanation:
Assuming the teacher is not of similar age to the students, their higher age would pull the mean higher than if the teacher were not included, where the median would not be pulled by this extreme value.
