The sum of two consecutive integers is at least 36. What is the least possible pair of integers? A. 16 and 17 B. 17 and 18 C. 18 and 19 D. 19 and 20

Answers

If you would like to know the least possible pair of integers, you can find this using the following steps:

integer ... n
the sum of two consecutive integers ... n + (n+1) = n + n + 1 = 2 * n + 1
is at least 36 ... >= 36

n + (n+1) >= 36
2 * n + 1 >= 36
2 * n >= 36 - 1
2 * n >= 35      /2
n >= 35/2
n >= 17.5

n = 18: 18 + (18+1) = 18 + 19 = 37 >= 36

The correct result would be C. 18 and 19.

Sandra conducted an observational study to learn how relationships with family affect happiness. She surveyed 500 people in her hometown and found that 85% say that positive relationships with family members make them happy. What could be the conclusion of her study?

Answers

She may conclude that in her hometown, a majority of people experience greater happiness thanks to positive relationships. However, in order to apply this to a greater population, she will have to use a larger sample of people.
Since this is an observational study and not an experiment, she can only conclude that there may be a link between closeness with family and happiness but we cannot say that closeness with family results in happiness.

Complete the statements about the key features of the graph of f(x) = x5 – 9x3.As x goes to negative infinity, f(x) goes to ________ infinity, and as x goes to positive infinity, f(x) goes to _______ infinity.

Answers

we have

f(x) = x^(5) -9x^(3)

using a graph tool

see the attached figure

in the graph observe that

As x goes to negative infinity-------> f(x) decreases

and

As x goes to positive infinity-------> f(x) increases

therefore

the answer is

As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity.
