Answer:
Its 41 mph and 55 mph
Step-by-step explanation:
Answer:
y= -2x-5
Step-by-step explanation:
First find the gradient of the first line
m=
m=
m=1/2
From this we can find the gradient of the perpendicular line, or the normal.
m1 × m2 = -1
Replace m1 with 1/2
1/2 × m2 = -1
m2= -2
Substitute values into
y-y1=m (x-x1)
y-3=-2 (x+4)
y-3=-2x -8
y=-2x-5
Answer:
Your answer would require a 7 in the hundreds place
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
A is not right as we don't know the formula used so we cant say the x intercept
B is not right as the function is not liner
C The function is not liner
That leaves D!
hope this helps!
Answer:
Step-by-step explanation:
Independently selected samples measures scores on the same variable but for two different groups of cases while Paired-samples measures scores on two different variables but for the same group of cases.
In case study 1, the sample is independently selected; a random sample of 100 science majors and a random sample of 75 liberal arts majors are selected: two different group of cases and just one variable, to compare the mean number of hours.
In case study 2, the samples are paired, a random sample of science majors is selected. Each student in this sample is asked for two data values: a group of case but two different variables; how much money they spent on textbooks in the spring semester and how much money they spent on textbooks in the fall semester were measured.
In case study 3, the samples were independently selected. Two different group of cases; a random sample of science majors is selected. A separate random sample of the same size is selected from the population of liberal arts majors were measured for just one variable the mean amount of time spend in campus.
