His mistake was that he did not use a random sample. His tried to show that playing games would give him higher grades which his study does not decisively conclude because the people around him that play games are likely to be in the same academic caste as him, which skews his data. Choice B would be the best because he's not testing any variables, rather just collecting the unadultered data of the group.
Hello,
I would be happy to help.
For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3
Remember to use the order of operations!
Good luck,
MrEQ
For this case, the first thing we must do is calculate the number of attendees who will make purchases.
We have then:
(42000) * (0.65) = 27300
We are now looking for the number of attendees that each vendor will attend.
We have then:
N = (27300) / (10)
N = 2730
Answer:
the average number of customers each will serve is:
N = 2730
Answer:
Tax would be 4500$
Step-by-step explanation:
15/100 = x/30000
Do 15 x 30000 = 450000
then divide 450000 by 100 = 4500
Answer:
P=3
Step-by-step explanation:
8p =24
P= 24/8
P= 3
