For the scatter plot on homework:
a) The relationship is that the test score will increase, if the time spent on homework increases.
b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:
y=8(3)+40
y=24+40
y=64
c) The score would be 40% if no time was spent doing homework.
For the scatter plot on the rides:
a) y = -7/5x + 17.8
b) Anika worked 17.8 hours on Day 0
c) Decreased by 7/5 in a day.
Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Answer:
9.267
Step-by-step explanation:
Answer:
Probability of no one picking up a defective product = 571 / 1540
Step-by-step explanation:
Total number of items = 22
non-defective items = 22-3 = 19
Probability of all three picking up non-defective products
= 19/22 * 18/21 * 17/20
= 969/1540
Probability of at least one picking up a defective product
= 1 - 969/1540
= 571/1540
(=0.371, approx.)
Answer: A. x ≤ -3
x/3 - x-1/2 ≥ 1 would make x ≤ -3
Answer:
a) 94.2 cm
b) 78.5%
Step-by-step explanation:
a) since the square side = 30 cm
it means the diameter = 30 cm
then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm
b) the perimeter of the square = 30×4 = 120
94.2 for 120
x% for 100%
x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%
