20.7 degrees C
Step-by-step explanation:
Here's the easiest way to solve. Grab a calculator, or a piece of paper. (its simple math) SOOOO, The start is 19.4. Then, it rises 3.8. So add that to 19.4. That gives you 23.2, BuT, it falls again, back down 2.5 degrees. so take 23.2, and subtract 2.5 from it. That should give you 20.7 degrees.

Answer:
Mary Ann does have enough sugar
Step-by-step explanation:
3/5 is greater than 3/7 which means that she does have enough sugar. This is because the denominator 5 is smaller than the denominator 7, and since they have the same numerator, the fraction with the smaller denominator is greater.
You use elimination the get x=5 and then plug it in to get y=0 so the coordinate is (5,0)
Answer:
If we reject the null hypothesis based on the evidence, then our conclusion should be Option c.
If we do not reject the null hypothesis based on the evidence, then our conclusion should be Option a.
Step-by-step explanation:
We are given that the FDA wants to set up a hypothesis test to show that the new drug is safe before approving it by assuming it to be unsafe.
So, Null hypothesis,
= New drug is unsafe
Alternate Hypothesis,
= New drug is safe
<em>Now, if we reject the null hypothesis based on the evidence, then our conclusion should be that : </em>
There is sufficient evidence to believe that the new drug is safe because rejecting null hypothesis means that alternate hypothesis is accepted with required evidence.
<em>And If we do not reject the null hypothesis based on the evidence, then our conclusion should be that : </em>
There is insufficient evidence to believe that the new drug is safe because not rejecting null hypothesis means that we are not ready with enough evidence to assume that new drug is safe.
