A. Mr. Kent interviewed the 54 students as they are going to leave the school, it is not considered to be a random sample. It is because a random sample is when a set is taken from a population. Mr. Kent interviewed the 54 who are going to leave, meaning, he didn't take a set out of that 54, he took all of them. So it is not a random sample.
b. The question that Mr. Kent asked is considered to be a leading question, so it does not seem biased.
c. If there are 54 respondents.
51 = yes, the rest is no.
= 54 - 51 = 3
= 3 is now divided to 54 = 3/54
= giving an answer of 0.0555
= 0.0555 x 100
= 5.6%
= The percent of responses that says 'no' is 5.6%
The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so

Answer:
4/11
Step-by-step explanation:
I got the question wrong and it told me the right answer.
Answer:
18000
Step-by-step explanation:
If we want to find how many miles it travels in one hour, we need to find jow many seconds are in one hour because as the problem said, it's wheel rotates 5 times per second.
there are 3600 seconds in an hour, so we multiply 3600 by 5, and we get 18000.
The car travels 18000 miles in one hour.
Answer:
19 cases and 53 sodas
Step-by-step explanation:
First we will see how many cans did Jamie bought. As he bought 23 cases and each case has 12 cans, the total amount of cans is:
23 * 12 = 276 cans
If 223 were drunk, for getting the number of cases used we just need to divide the number of cases drunk between the number of cans each case contains:
223 / 12 = 18.58
As our answer must be an integer number, as cases are integer, we use 19 because 19 cases were opened. Notice that if we chose 18, this would imply 18*12=216 cans, which is less than the 223 drunk. So, 19 cases were used, although the last case was not drunk completely.
For getting the sodas left over we just need to subtract the amount drunk to the total:
276 - 223 = 53 sodas were left over
