Over 160 times as great
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
This problem has some information which does not pertain to the answer. The sample size of 60 is not important to the answer. (Sample size is a concern when it comes to deciding if the survey results are valid!)
75% of the sample says they're going to college, so assuming that the same proportion of students in the entire school is going to college, you need to find 75% of 900.
900 x .75 = 675, the same as the counselor's determination.
Hello from MrBillDoesMath!
Answer:
9, 11
Discussion:
From the attachment,
P = w + l + w + l
= 2w + 2l => as l = w + 2
= 2w + 2( w+2)
= 4w + 4
= 40 (given value)
4w + 4= 40 => subtract 4 from both sides
4w = 40 -4 = 36 => divide both sides by 4
w = 36/4 = 9
This implies that l = w+2 = 9 + 2 = 11
Thank you,

Hi so have you heard of KFC? It stands for keep flip change. You use it when adding or subtracting or when you're dividing fractions. So you keep the first part of the problem the same; you flip the sign of the second part, and change the sign of the third part. So -23.9- -9.3 becomes -23.9 + +9.3. So take away 9.3 from 23.9 and get 14.6. Whenever you add a positive to a negative like we do here, the answer will become a smaller negative number if the positive number is "smaller" than the negative number.
