Since both sides have the same base (4), we can add the exponents


subtract 5 from both sides:

<span>What is 3(6m) + m?
3(6m) + m =
m becomes 1m
9m + 1m =
10m
3(6m) + m is 10m when combining like terms. </span>
Answer:
1/3
Step-by-step explanation:
There were 18 students and six liked Much Ado About Nothing. So, you could write this as 6/18 which simplifies to 1/3.
There is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
<h3>What is a statistical hypothesis?</h3>
A hypothesis to test the given parameters requires that we determine if the mean score of the eighth graders is more than 283, thus:
The null hypothesis:

The alternative hypothesis:

From the population deviation, the Z test for the true mean can be computed as:


Z = 0.756
Note that, since we are carrying out a right-tailed test, the p-value for the test statistics is expressed as follows:
P(z > 0.756)
P = 0.225
Since the P-value is greater than the significance level at α = 0.14, we can conclude that there is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
