Answer:
10v^2
Step-by-step explanation:
(I'm assuming the 2's are all exponents)
3v^2 - 2v^2 + 9v^2 <- think of it as 3 - 2 + 9 = 10, then add the rest back on
10v^2

Answer:
y-8=2(x-9)
Step-by-step explanation:
m=y2-y1/x2-x1
10-8/10-9=2
y-y1=m(x-x1)
y-8=2(x-9)
Answer:
-1 2/27
Step-by-step explanation:
-1 1/2 × 5/6 + 3/14 ÷ 3/7 + 3/2 × 1/2
= -1 1/4 + 3/14 ÷ 1 13/14 × 1/2
= - 1 1/28 ÷ 27/28
= -1 2/27
Answer:
The student must score 79.75% to be invited to join the honors program.
Step-by-step explanation:
Let <em>X</em> denote the score of a freshman in the entrance exam.
It is provided that the average test score is 78%, with a standard deviation of 11%.
It is provided that the top 10% being offered admission to the university's honors program.
Let <em>x</em> denote the score eligible for being offered admission to the university's honors program.
Then, P (X ≤ x) = 0.90.
Then P (Z < z) = 0.90.
The corresponding <em>z</em>-score is, 1.28.
*Use a <em>z</em>-table<em>.</em>
Compute the value of <em>x</em> as follows:
Thus, the student must score 79.75% to be invited to join the honors program.
