Answer:
The 95% confidence interval the average maximum power is (596.0 to 644.0)
Step-by-step explanation:
Average maximum of the sample = x = 620 HP
Standard Deviation = s = 45 HP
Sample size = n = 16
We have to calculate the 95% confidence interval. The value of Population standard deviation is unknown, and value of sample standard deviation is known. Therefore, we will use one sample t-test to build the confidence interval.
Degrees of freedom = df = n - 1 = 15
Critical t-value associated with 95% confidence interval and 15 degrees of freedom, as seen from t-table = = 2.131
The formula to calculate the confidence interval is:
We have all the required values. Substituting them in the above expression, we get:
Thus, the 95% confidence interval the average maximum power is (596.0 to 644.0)
Hello!
Explanation:
First, you had to do is multiply by 3 from both sides of an equation.
And then simplify by equation form. You can also multiply by the numbers.
Answer:
<u><em>*The answer must have a positive sign.*</em></u>

The degree of the provided polynomial is 18, and the leading term is √7.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
We have given an expression:
As we can see in the expression the greatest degree is 18.
So the degree of the polynomial is 18
And the coefficient of the variable which has a height degree is the leading term.
The leading term = √7
Thus, the degree of the provided polynomial is 18, and the leading term is √7.

Answer:
C. 10 s.
Step-by-step explanation:
When the hammer reaches the ground the height is 0 m, so:
-t - 2t + 30 = 0
-3t = -30
t = -30/-3
= 10 seconds.
