Which statement best describes how to determine whether f(x) = x3 + 5x + 1 is an even function?

1 answer:

7 0

I have my notes here that will help you in answering the problem:

Test to determine if a function y=f(x) is even, odd or neither: Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even. If f(-x) = - f(x), the function<span>is odd.

I hope my answer has come to your help. God bless and have a nice day ahead!

Mean = (89 + 90 + 87 + 95 + 86 + 81 + 102 + 105 + 83 + 88 + 91 + 79)/12 = 1,076/12 = 89.67

a.) 95% C.I. = 89.67 + or - 1.96(0.23) = 89.67 + or - 0.4508 = 89.22 to 90.12

b.) 99% C. I = 89.67 + or - 2.575(0.23) = 89.67 + or - 0.5923 = 89.08 to 90.26

shutvik [7]

Using Venn probabilities, it is found that the probability that he receives an offer on at least one of the jobs is given by:

D. 0.80

<h3>What is a Venn probability?</h3>

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

In this problem, we have that:

50% chance of getting an offer on Job A, hence P(A) = 0.5.

60% chance of getting an offer on Job B, hence P(B) = 0.6.

30% chance of getting an offer on both jobs, hence $P(A \cap B) = 0.3$ .

Then, the probability of getting an offer on at least one job is:

$P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.5 + 0.6 - 0.3 = 0.8$

Hence option D is correct.

the length of a rectangle is five times its width. if the perimeter of the rectangle is 96 ft, find its area.

romanna [79]

Answer:

lets say that the length is L and the width is W. With the given info, we can say that L=5W.

We know that the perimeter is all four sides added, so..

5W*4=20W

20W=96

W=4.8

L= 5*4.8=24

Area is equal to 24*4.8, which is 115.2

Voila! Your answer is 115.2 sq. ft!
