Answer:
Step-by-step explanation:
The hypotheses are:
Null Hypothesis

Alternative Hypothesis

Since the t-statistic score is greater than the critical t-score, so the decision is to reject the null hypothesis.

Answer:
Your answer would be 9.
Step-by-step explanation:
You always do parenthesis first, 9-6 is 3, then you would do division 3÷3 is 1 then you multiply 4×2 and that would be 8, finally you would at the 8 and the 1 and that would give you 9 as your answer. Hope this helps
I think the answer is 7.6m
3 hours 1/4 times two equals 30 1/2 times 2 equals 1 hour 3/4 times 2 equals 90. 30 plus 60 plus 90 180. 180 divided by 60 is 3 so three hours.
Answer:
- a) x = 4
- b) y = 1.25x + 15
- c) (-12, 0)
Step-by-step explanation:
a) PQ is parallel to the y-axis and contains point (4, 5).
<u>It means its equation is:</u>
b) RQ is parallel to OP.
Parallel lines have equal slopes.
<u>Find the slope of OP:</u>
RQ has slope of 1.25 and passes through (- 8, 5).
<u>Find its equation using point-slope form:</u>
- y - 5 = 1.25(x - (-8))
- y - 5 = 1.25x + 10
- y = 1.25x + 15
c) <u>The x-intercept is determined at y = 0:</u>
- 0 = 1.25x + 15
- 1.25x = - 15
- x = - 15/1.15
- x = - 12
