Answer:
I would say B
Step-by-step explanation:
when you are going down you tend to go faster because of gravity. So you would go down, up, down, up, and a little down. This would make B the answer because the speed is increasing when it goes down so that is the only answer that would make sense. Hope this helped! Have a good day! :)
Answer:
B. Paired T Test
B. H0: μd = 0 and Ha: μd < 0 where μd= mean difference in blood pressure (calculated as aspirin - placebo)
Step-by-step explanation:
As the experiment is based on the difference between the results of a pair, the most appropiate test is a paired t-test.
If the 80 people group had been dividided in 2 and then compare the means for each group, it would have been a independent samples t-test.
For each pair, a variable d (for difference) is calculated and used as the outcome sample to perform the test.
Then, the null hypothesis will state that the population mean for this difference is not significantly different from 0, and the alternative hypothesis claiming it is signficant different from 0.
The sample means for the treatment group and the placebo is not individually calculated, as only the difference for each pair is used as sample in a paired t-test.
Answer:
D. The equator would become warmer, while the poles become colder
Step-by-step explanation:
So the reason in this is actually due to the fact that the ocean currents bring heat from the equator. A study was actually done a bit ago that stated that “Europe would drop 5 to 10 degrees Celcius.“

Also this is more of a science question in my opinion LOL.
Answer:
10 2/5 meters long
Step-by-step explanation:
first turn 20 4/5 into an improper fraction (104/4) then multiply that by 1/2 and you get 104/10 but simplify it to 10 2/5
Hope this helps!
The true statements are;
1) AB + BC = AC
Length of BC = |6 - 1|
2) ∠JMK = 50°
∠KML = 35°
<h3>How to Interpret Number Line intervals?</h3>
1) From the given number line interval, we can deduce the interpretation as follows;
AB + BC = AC
Length of BC = 5 units or |6 - 1|
Length of B = 3 Units
2) We can see that ∠JML is an angle triangle. Thus, ∠JML = 85°. Thus;
6x + 2 + 4x + 3 = 85
10x + 5 = 85
10x = 85 - 5
10x = 80
x = 80/10
x = 8°
Thus;
∠JMK = 6(8) + 2
∠JMK = 50°
∠KML = 85° - 50°
∠KML = 35°
