Answer:</h3>
<u><em>The height of the rectangular prism is </em></u><u><em>2 yards in length.</em></u>
<h3>
Step-by-step explanation:</h3>
By knowing that the volume of a rectangular prism is length * width * height, it is rather simple to find the answer.
Firstly, you'll multiply the lengths that you already know.
(length * width)
<em>3/4 * 1/3 ---> 0.25 or 1/4</em>
Next, you'll divide the volume by this amount to find the unknown height.
<em>1/2 ÷ 1/4 ---> 2</em>
Your height would be 2 yards in length.
Answer:
Reject H0
Step-by-step explanation:
Given :
H0: The frequencies are equal. H1: The frequencies are not equal
Category f0 A 10 B 30 C 30 D 10
Total f0 = (10 + 30 + 30 + 10) = 80
Expected frequency is the same for all categories :
Expected frequency = 1/4 * 80 = 20
χ² = Σ(observed - Expected)² / Expected
χ² = (10-20)^2 / 20 + (30-20)^2 /20 + (30-20)^2 / 20 + (10-20)^2 / 20
χ² = (5 + 5 + 5 + 5) = 20

Answer: 12.5 litres
Step-by-step explanation:
The SUV takes 2.5 litres for every 20 km driven.
The trip to work is 20 km which means that going to work costs Marie's father 2.5 litres every day in fuel.
In a week, there are 5 working days.
The amount of fuel used per week is therefore:
= 2.5 * 5
= 12.5 litres
