(a2 + 5) • (a2 + 1) is your answer to this question.
It can’t, we made a chart in my class, with parallelograms and the top and kites and trapezoids are on the same level so they can’t be the same
Answer:
He needs to complete a distance of 4,030 yards around the rink to make a total skating distance of 3 miles
Step-by-step explanation:
In this question, we are asked to calculate the number of yards needed to complete 3 miles skating around a rink.
We proceed as follows;
First, we can see he has skated 5 times around a rink that has a distance of 250 yards. His total distance covered would be 250 * 5 = 1250 yards
Now he is looking at completing 3 miles, we need to know the number of yards in 3 miles.
Mathematically, 1 mile = 1760 yards
3 miles = 3 * 1760 = 5,280 yards
To know the number of yards he need to skate more, we simply carry out a subtraction;
5,280 yards - 1250 yards = 4,030 yards
Answer: c) increase
Step-by-step explanation:
- A sample is a finite subset of the entire population on which research statistical test regarding his/ her objective .
As the sample size increases it comes closer to the population size, and so converge to a better result of researcher's analysis.
It means the size of the sample is proportional to the power of their statistical tests.
∴ As the size of the sample increases the power of statistical test increases.
Hence, If a research team increases the sample size for a study, the power of their statistical tests will <u>increases</u>.
Therefore , the correct answer is : c) increase
Answer:
The value of x is 64
Step-by-step explanation:
Given:
Length of the Legs of the triangle = 6 and √x
Hypothenus = 10
Required
Find x?
The legs of a rectangle is what is regarded to as the adjacent and the opposite sides of the triangle.
Assuming the following
Adjacent = 6 and Opposite = √x
We can then solve the given example using Pythagoras theorem as foloes;
By substituting 10 for Hyp; 6 for Adj and √x for Opp
Simplify
Collect Like Terms
Hence, the value of x is 64
