<h3>
Answer: d. Contingency table</h3>
Explanation:
It's most effective to use a contingency table because we have two variables here: 1) the responses, and 2) the party affiliation.
We can have the responses along the rows and the party affiliation along the columns, or vice versa.
See the example below. The values are completely random simply for the purpose of the example (and not drawn from any real life data source).
Answer:
Step-by-step explanation:
Let x represent the unknown number.
We are asked to convert the verbal expression with its equivalent algebraic expression..
Five more than a nine times square of a number.
Square of the number would be .
Nine times square of the number would be 9 multiplied by as:
.
Five more than a nine times square of a number would be plus 5 as:
Therefore, our required expression would be .
Answer: (x−2)(x−2)
The middle number is -4 and the last number is 4.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get 4
Can you think of the two numbers?
Try -2 and -2:
-2+-2 = -4
-2*-2 = 4
Fill in the blanks in
(x+_)(x+_)
with -2 and -2 to get...
(x-2)(x-2)
Answer:
(x−2)(x−2)
so the answer is D.
Assuming a direct proportional variation.
The answer to your question would be A.
