Answer:
<u>Options B and D</u>
Step-by-step explanation:
6x² + x - 1 = 0
6x² + 3x - 2x - 1 = 0
3x(2x + 1) - 1(2x + 1) = 0
(3x - 1)(2x + 1)
x = 1/3 and -1/2
<u>Options B and D</u>
Answer:
19.2
Step-by-step explanation:
You get the mean of a set of numbers by adding them and dividing the sum by how many numbers there are. In this case, you don't know what the individual 8 numbers are, but you can find out what they add up to.
Mean = (sum) / 8
17 = (sum) / 8
17 x 8 = sum
136 = sum
Now take out the numbers 9, 11, 20, which reduces the sum by 40. There are 5 numbers left and they add up to 136 - 40 = 96.
The new mean is 96 / 5 = 19.2
Answer:
Decimal 1/20= .05
Percent 1/20= 5%
