Answer:
The provided statement is True.
Step-by-step explanation:
Holding a variable constant implies that there are no kind of relationship between the variables and the treatments.
Holding a participant variable constant has the double advantage:
(1) preventing the variable from becoming a confounding variable
(2) reducing variance within groups.
A confounding variable effects both the dependent and the independent variable remarking a relationship between the two.
Variation within group implies the difference caused by the individual values of each group.
Thus, the provided statement is True.
Desmond's times are proportional. for every 2 laps he takes 146
146 / 2 = 73
292 / 4 = 73
584 / 8 = 73
Maria's time are not proportional
150 / 2 = 75
320 / 4 = 80
580 / 6 = 96.67
Answer:
x = 111 degrees
Step-by-step explanation:
the angle next to 164 degrees :
any line = 180 degrees, so 180 - 164 = 16 degrees
now you have two out of three angles in the triangle. All three angles of every triangle must add together to equal 180, so
180 = 53 + 16 + x
or
x= 180 - 53 - 16
x=111 degrees
