Find the mean of 10, 8, 5, 11, 12, 9, 6, 3, 15, and 23.
11.2
10
10.2
11.3
Correct answer is C
\(\frac{10 + 8 + 5 + 11 + 12 + 9 + 6 + 3 + 15 + 23}{10}\)
= \(\frac{102}{10}\) = 10.2
From the cyclic quadrilateral above, find < TSV
60o
80o
70o
50o
Correct answer is B
< TVS = 180o - (80 + 20)
= 180 - 100 = 80o
If Q is a factor of 18 and T is prime numbers between 2 and 18. What is Q\(\cap\)T?
(2,3)
(2,3,18)
(2,3,9)
(2,3,6)
Correct answer is A
Q = {1,2,3,6,9,18}, T = {2,3,5,7,11,13,17}
Q\(\cap\)T = {2,3}
Solve for x and y respectively
3x - 5y = 9
6x - 4y = 12
\(\frac{3}{4}\), 1
\(\frac{4}{3}\), 1
\(\frac{3}{4}\), -1
\(\frac{4}{3}\), -1
Correct answer is D
3x - 5y = 9 ------x2
6x - 4y = 12 -----x1
6x - 10y = 18
-6x - 4y = 12
____________
\(\frac{6y}{-6}\) = \(\frac{6}{6}\)
y = -1
in eq (1) 3x - 5y = 9
3x - 5(-1) = 9
3x + 5 = 9
3x = 4
x = \(\frac{4}{3}\)
