Distribute.
8x - 24 + 3x = 6x + 1
Combine like terms.
11x - 24 = 6x + 1
5x = 25

60 more students voted for Kevin
Step-by-step explanation:
Given
total students = 300
Voted for Jennifer = 40%
Voted for Kevin = 60%
We will find number of students for one of them and then will subtract from total to find the others.
So,
Students who voted for Jennifer:
Students who voted for Kevin
=
In order to calculate that how many more students voted for Kevin :
180-120 = 60
Hence,
60 more students voted for Kevin

You are correct
12.2^2 x 3.14 x 6.1 = 2850.9
Answer:
Step-by-step explanation:
Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)
The null hypothesis: u = hypothesized mean
Alternative hypothesis: u > u0 or u < u0 for a one tailed test
Alternative hypothesis for a two tailed test: u =/ u0
To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value
Observed z score > critical z score for both the one and two tailed test.
Or using p value:
P-value > alpha for a one tailed test
P-value > alpha/2 for a two tailed test
Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.
