Answer:
Step-by-step explanation:
Alright, lets get started.
We first need to find the surface area of the ramp without its base.
The ramp consists 4 sides two triangles and two rectangles.
Area of 1 triangle = 
Area of 2 triangle = 42
Area of top rectangle = 
Area of back rectangle = 
So total area = 
square feet
We are asked to paint two coats of paint means we have to double the area.
So the double area is = 
80 square feet requires = 1 quart of paint
994.8 square feet requires = 
12.4 quart can't be purchased so complete number of quart will be 13 quart. : Answer
Hope it will help :)
Hey there!
10 to the fifth power is equivalent to the expression:
10 x 10 x 10 x 10 x 10 because you are multiplying 10 by 10 5 times.
Hope this helps you.
Have a great day!
The answer is C. The 4th period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd period class.
Answer:
Step-by-step explanation:
Given that a study found that the average stopping distance of a school bus traveling 50 mph was 264 feet.
Sample taken showed the following results
Since population std deviation is known and sample size is large, z test can be used.
(Left tailed test)
Mean difference = 
Std error = 
Z = test statistic = mean diff/std error
= 
p value = 0.00017
Since p < alpha our 0.05 we reject null hypothesis
There is evidence to show that mean is less than 264 feet
(Assumptions:
Sample are randomly drawn
Sample represents the population
