Answer: approximately 10.8 centimeters
Step-by-step explanation:
We have a square, where each side measures approx. 4.25 in
Now we know that 1in ≈ 2.54 cm
Then, in 4.25 in, we have 4.25 times 1 inch, so we have 4.25 times the length of 2.54 cm
So the approximate measure of the sides in centimeters is:
4.25*(2.54)cm = 10.8 cm
So we have that each side measures approximately 10.8 centimeters
First, add 1/2 and 1/4 which equals to 3/4 and then use cups to teaspoons so it is 3/2.
Answer:
4.5 feet cubed
Step-by-step explanation:
The volume of a prism is found with the formula V = l*w*h.
Here l = 2, w = 1.5 and h = 1.5.
The volume is V = 2*1.5*1.5 = 4.5.
Answer:
Estimate of the standard error of the mean = 0.38 lb
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 10.87 lb
Sample size, n = 131
Standard deviation, σ = 4.31 lb
We have ti find the estimate of the standard error of the mean.
Formula for standard error:
Putting values, we get,
0.38 lb is the standard error of the mean.
