As already mentioned, the volume for a rectangular prism, namely a box in this case, is just the product of its dimensions, length * width * height.
now, as far as another one... hmm is easier if you post in the channel, that way I can include any graphs if needed or tables and such.
so, what happens if you double up the dimensions?
notice, how many times the new size is, is 8 times the original.
For this case you can write a weighted average expression to find the average number of tickets sold per child.
We have then that an expression that can represent this average is the following:
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
answer
an expression for the average number of tickets sold per school child is
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))

Answer:
x=3/2
Step-by-step explanation:
Move the to lines,
2x=3
Isolate x
2x/2=3/2
x=3/2
Answer:
A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions. a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor? b. For 95% confidence, determine the margin of error (+ lbf) c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators? d. lbf) if 50 insulators were tested.
