What is the factor form of n^-25 (n—25)(n-1) (n-5)(n+5) (n+5)(n+5) (n-25)(n+1)

1 answer:

6 0

To solve this problem you must apply the proccedure shown below:
1- You have the following quadratic expression <span>n^2-25.
2. When you factor, you obtain:
(n-5)(n+5)
3. To verify this is true, you can apply the distributive property, as below:
</span><span>n^2+5n-5n-25
</span><span>n^2+25
Therefore, as you can see, the answer is the second option, which is:
(n-5)(n+5)</span>

Jerry is a judge. He hears 5 cases in 2 3/8 hours. How many cases does he hear per hour

Serggg [28]

Answer:

Jerry does $2.11$ cases per hour (Rounded to 2 decimal places). As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

Step-by-step explanation:

to find the number of cases per hour, we have to divide the number of cases by number of hours taken for those cases,

Number of cases per hour = $\frac{5cases}{2\frac{3}{8} hours}$

= $\frac{5}{\frac{19}{8} } \\$ cases per hour

= $\frac{5*8}{19}$ cases per hour

= $\frac{40}{19}$ cases per hour

= $2.11$ cases per hour (Rounded to 2 decimal places)

As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

Harman [31]

According to the p-value, the correct option regarding the decision of the test hypothesis is:

v. No, because 0.283 > 0.05.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, we test if the proportion is still of 0.53, that is:

$H_0: p = 0.53$

At the alternative hypothesis, we test if it has increased, that is:

$H_1: p > 0.53$ .

<h3>What is the decision according to the p-value?</h3>

If p-value > significance level, we do not reject the null hypothesis.

If p-value < significance level, we reject the null hypothesis.

In this problem, the p-value is of 0.283 > 0.05, hence there is not sufficient evidence to conclude, at the significance level of a = 0.05, that the proportion of all car owners in the United States who own American-made cars has increased from what it was ten years ago, which means that option V is correct.
