Ms. Velez will use x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.Which inequalities model the situation?
Choose exactly three answers that are correct.
Answers
So,
Ms. Velez can spend $200 on her project. She wants the red bricks to be less than half of the number of gray bricks. x or red bricks < 1/2y or grey bricks x < 1/2y
x + y ≤ $200
x < 1/2($200)
y > 1/2($200) AND y < $200

The distribution of GPAs is normally distributed with a mean of 2.7 pounds and a standard deviation of 0.3. Approximately what percentage of students has GPAs above 3.0?
Answers
The best answer to this statistic question would be 15.7% or, if rounded off, 16%. This is because those students who have GPAs are approximately at least 1 standard deviation away from the mean and more - which means that 84% of the GPAs are less then 3 pounds. I subtracted 84 from 99.7 (which is the whole distribution's percentage) and came up with 15.7.
