A) To find the edge length from the volume you use the formula:
e = V¹ˡ³ (to the power of 1/3) where e is the edge length.
Substitute in the volume:
e = 64000¹ˡ³
Solve:
Edge length = 40 inches
b) To find the surface area from the volume you use the formula:
s = 6V²ˡ³ (to the power of 2/3) where s is the surface area.
Substitute in the volume:
s = 6 x 64000²ˡ³
Solve:
s = 384000²ˡ³
Surface area = 9600 square inches
Answer:
3.2
Step-by-step explanation:
Here we are told that a population has a standard deviation of 32 and that we have a sample of size 100 from this population that are asked for the standard error of the sampling distribution. Now it would be important to know what statistic we are taking from these samples. Now we would need to know what what statistic we're taking from these samples. Um I'm assuming that we're talking about sample averages in this case the standard error is well, let's sample averages are just distributed like this. They are so we have anna's big, which means that our sample averages are going to be approximately normally distributed. The mean of the sample averages will be equal to the mean of the population, and the standard air of the sample averages will be equal to the population. Standard deviation divided by the square root of the sample size. So this is our standard error of the sampling distribution, And so this is equal to 3.2. So that is your answer.

Answer:
Ben received: £140
Step-by-step explanation:
Total amount = £240
Given ratio: 5:7
It means £240 is divided into 12 parts
So 1 part will be equal to: £240/12
1 part = £20
Now given ratio is:
5:7
Multiplying each share with £20
5*(£20) : 7* (£20)
£100: £140
So according to ratio amounts:
Alex received: £100
Ben received: £140
I hope it will help you!
