The function f(x) is even if:
f(-x) = f(x)

f(x) is odd if:
f(-x) = -f(x)

Plug in -x into f(x):
f(-x) = 5(-x)^2 - 2
f(-x) = 5x^2 - 2

We got back our original f(x) by plugging in -x, so f(-x) = f(x), and therefore the function is even.

As part of a statistics project, Andrea would like to collect data on household size in her city. To do so, she asks each person
strojnjashka [21]

Answer:

Charlie did not use any randomization; he took a convenience sample.

Step-by-step explanation:

The first question we need ask is whether his classmates make up the population of the city? Or does it mean that his classmate will give unbiased representation of the entire city? Because we are certain there are many other schools within the city of interest. Less assume he can do that, what will happen to all other schools? These are many other factors rendered his choice of sampling inappropriate for this study.

Therefore, the process is not random but convenience sample, even though they might give information about their various household sizes, it might not give the true picture of the city he is trying to investigate.

The best approach should have been a probability sampling techniques, preferably a systematic random sampling approach. If he has followed this process of sample selection, it will give a more reliable and well representative sample to determine the households size in the city of his interest.

HELP please hurry!!
Dmitriy789 [7]

Answer: D

Step-by-step explanation:

-3x + 1 < 7

subtract 1 from both sides

-3x < 6

divide each side by -3

x > -2 (flip the greater than/less than sign because you divided by a negative)

-2 is not included so it is an open dot, and answers include all numbers greater than -2 so the answer will be D. Hope this helps!
