2 1/4 hours=2.25 hours
ran 13 miles in 2.25 hours, so I just need to take 13 miles divided for 2.25 which equal 5 7/9. As a result, my average speed is 5 7/9 miles per hour. Hope it help!
Answer:
9z
Step-by-step explanation:
4th root of z = z^1/4
=> 3 * z^1/4
=> 3z^1/4
3z^1/4 * 3z^3/4
=> 3 x 3 x z^1/4 + 3/4
=> 9z^4/4
=> 9z^1
=> 9z
<span> The surface area of a right prism can be calculated using the following formula: SA 5 2B 1 hP, where B is the area of the base, h is the height of the prism, and P is the perimeter of the base. The lateral area of a figure is the area of the non-base faces only.</span>
Answer:
It is not proportional
Step-by-step explanation:
To figure out if something is proportional they have to equal the same thing.
As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.
Now we come to the 0.08 and the 0.8.
They are not the same thing the 0.08 has an extra 0.
So this is not proportional

Answer:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case is:
C. p-value
Step-by-step explanation:
Data given and notation
n represent the random sample taken
estimated proportion of interest
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion i 0.72 or no.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion is significantly different from a hypothesized value 
.
For this case the only probability that can be calculated from the statistic calculated is the p value given by:
And the best answer for this case is:
C. p-value
