Answer:
105 inches
Step-by-step explanation:
Because the base is a rectangle, that is the best place to start. The first step is to multiply 5 by 6 which results in a base area of 30 inches. Because it is a triangular prism, we then multiply the base and divide by two. The formula for this equation is V=(width*length*height)/2
The final answer is 105
Answer:
162 cubes
Step-by-step explanation:
The formula for finding the volume of a rectangular prism is length x width x height.
6 x 3 x 4.5 = 81
Since each cube is only half a centimeter, we need to multiply this by two.
81 x 2 = 162 cubes
Yes it is 15 because 1+2 is 3 3+3=6 6+4=10 and finally 10+5=15
Answer:
75% of the households have between 2 and 6 televisions
Step-by-step explanation:
From the question, we can deduce the following;
sample size n= 8
sample mean μ = 4
standard deviation σ = 1
Using Chebychev’s theorem;
P(2 ≤ X ≤ 6) = P(2-4 ≤ (X - μ) ≤ 6-4)
= P(-2 ≤ (X-μ) ≤ 2) = P(|X-μ| ≤ kσ) ≥ (1 - 1/k^2) ≥ (1- 1/2^) = 1- 0.25 = 0.75 ( same as 75%)
