False. The sum is -4:
-5 + -2 = -7
-7 + 3 = -4
For the various values of X the values of Y are given as follows
X=-1; Y=3
X=0; Y=2
X=1; Y=3
X=2; Y=6
X=3; Y=11
Step-by-step explanation:
Step 1:
Let us consider the given expression as
Step 2:
Let us discuss the value of Y for the various values of X
If X = -1, Y = (-1)² + 2 = 3
If X = 0, Y = (0)² + 2 = 2
If X = 1, Y = (1)² + 2 = 3
If X = 2, Y = (2)² + 2 = 6
If X = 3, Y = (3)² + 2 = 11

Step-by-step explanation:
Answer:
<h2>
N=-2</h2>
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
2n+1−1=−3−1
2n=−4
Step 2: Divide both sides by 2.
2n/2=−4/2
n=−2

Answer:
Given:You sample 160 men, and 25% own cats
You sample 120 women, and 20% own cats.
To Find : Find the test statistic, rounded to two decimal places.
Solution:
You sample 160 men, and 25% own cats.
No. of men have cats =
=
So,
You sample 120 women, and 20% own cats.
No. of women have cats =
=
So,
We will use Comparing Two Proportions
Let and be the probabilities of men having cat and women having cat receptively
Formula of test statistic :
Substitute the values
test statistic :
test statistic :
So, test statistic is 0.986
