Answer:
we can infer that carbon emmisions have increased over the years since the problem seems to grow so we can also infer that productions of products are in higher demand so therfore that means more emmisions
Step-by-step explanation:
s=2r+3x
Move 2r to the other side. Sign changes from +2r to -2r.
s-2r=2r-2r+3x
s-2r=3x
Divide by 3 for both sides
s/3-2r/3=3/3x
x=s/3-2r/3
Answer: x=s/3-2r/3
Answer:
B. i and iii
Step-by-step explanation:
There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution
Hypothesis
H0: u <= 15
H1: u > 15
Mean of x = 16.6
S = 2.22
Test statistic used is t test
16.6 - 15 / 2.22/√24
= 3.531
We find the critical value
Degree of freedom = 24-1 = 23
This is a one tailed test
Critical value = 1.714
We find p value using Ms excel T distribution function
= 0.000894
To make the decision
3.531 > 1.714 so we conclude that
I.) Reject null hypothesis
Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.
The answer option Is B
