Answer:
10 feet.
Step-by-step explanation:
The formula for the area of a triangle is A=1/2bh
where A is the area B is the base and H is the height.
The area is 60 and the base is 12 so the formula will become
60=1/2*12*h
60=6*h
by dividing both ends by 6
10=h
the height of the triangle is 10.
I hope this helps :)

Answer:
The horizontal distance traveled by the ball before it hits the ground is 550 ft
The graph in the attached figure
Step-by-step explanation:
we have
Using a graphing tool
we know that
The horizontal distance traveled by the ball before it hits the ground is equal to the horizontal distance from the origin to the x-intercept of the graph
so
The horizontal distance is 550 ft
see the attached figure
Answer and Step-by-step explanation: The null and alternative hypothesis for this test are:


To test it, use F-test statistics and compare variances of each treatment.
Calculate F-value:



F = 1.8356
The <u>critical value of F</u> is given by a F-distribution table with:
degree of freedom (row): 20 - 1 = 19
degree of freedom (column): 20 - 1 = 19
And a significance level: α = 0.05
= 2.2341
Comparing both values of F:
1.856 < 2.2341
i.e. F-value calculated is less than F-value of the table.
Therefore, failed to reject
, meaning there is <u>no sufficient data to support the claim</u> that sham treatment have pain reductions which vary more than for those using magnets treatment.
