Solution :
It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.
Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.
(9x-2) - (5x+6) =
4x-8 , this is your profit function
Answer:
78%
Step-by-step explanation:
70 = 0.50 (62) + 0.50 (x)
70 = 31 + 0.5x
39 = 0.5x
x = 78
You must get at least a 78% on the test to have at least 70% in the class.
Choice 1. f(5)=5-3 which equals 2
Answer:
2(4x-6)
4(2x-3)
8(x-3/2)
Step-by-step explanation:
find all factors of 8 other than 1, you should have 3
divide the whole equation by the factor then multiply by the factor
2(8x-12)/2 = 2(4x-6)
4(2x-3)
8(x-3/2)
