Reflection. A reflection is what appears to be the same distance from the other side of the mirror.
Answer:
y= -x+6
Step-by-step explanation:
The equation was in point slope from, so you had to solve for y using inverse operations. The slope of x is -1 because -x = -1x.
Let x and x+1 be the two consecutive integers.
Then their sum is x + (x+1) = 2x + 1.
Answer:
(i) She gives each student a pretest. Then she teaches a lesson using a computer program. Afterwards, she gives each student a posttest. The teacher wants to see if the difference in scores will show an improvement.
Step-by- Step
The situation is a case of matched or paired samples since the samples are dependent. The two measurements are drawn from the same pair of individuals The parameter that is tested using matched pairs is the population mean and this is what teacher intends to use a hypothesis test for.
