Answer:
Step-by-step explanation:
Let X represent for males and Y for females
Given that
Group Group One Group Two
Mean 84.00 78.00
SD 4.00 8.00
SEM 1.26 2.53
N 10 10
SEM is calculated as
for each group

(Two tailed test at 5% significance level)

Since p <0.05 we reject H0 and there is significant difference between the groups.
A.Exam scores were significantly higher in the male group, t(18) = 2.83, p < .05B
Answer:
8x+3y+6=0
transfer 8x and 6 to the equal side which becomes
3y=-8×-6
Answer:
The transformation

maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus,
, and the y-coordinate first transforms as
, and is then shifted by 1; thus, it transforms as
.
So we have the full transformation

Answer:
Step-by-step explanation:

Counterclockwise is a rotation towards the left, as in the triangle will move to the position before it.
The correct answer is the fourth option, triangle DEF.
Hope this helps! :)
