PQ + QR + RS = 18
PQ = 2x - 6; QR = 1; RS = x - 4
2x - 6 + 1 + x - 4 = 18
3x - 9 = 18
3x = 27
x = 9
Answer: C. 9
What this question is asking you to find 80% of 25. 10% of 25 is 2.5 because there is always a decimal point directly to the right of the ones place. (25.0)
You would move the decimal point over one place to find 10% of a given number. How I would approach this is to multiply 2.5 by 8 to find 80% of 25
2.5 x 8 = 20
80% of 25 = 20
You can expect the work group to get done 20 out of 25 of their objectives per quarter
there is about a 4% chance that they answer yes and about an 8% chance they are male.
Yes probability- 6/151≈.039 which rounds to .4 or 4%
Male probability- 12/151≈.079 which rounds to .8 or 8%
