a straight trail with a uniform inclination of 11 degrees from a lodge at an elevation of 700 feet to a mountain lake at an elev
kozerog [31]

Answer:

r = 38584.155\,ft

Step-by-step explanation:

The length of the trail is obtained by the definition of sine, where height is the opposite leg and length is the hypotenuse:

\tan 11^{\textdegree} = \frac{8200\,ft-700\,ft}{r}

The length of the trail is:

r = 38584.155\,ft

Many consumer groups feel that the U.S. Food and Drug Administration (FDA) drug approval process is too easy and, as a result, t
Zigmanuir [339]

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, H_0 = New drug is unsafe

 Alternate Hypothesis, H_1 = 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.

natita [175]

Answer:

B: Survey 3 randomly selected students from every homeroom.

Step-by-step explanation:

This would be the best way to survey, because all the others have some sort of variable. The principle doesn't know who buys lunch and who doesn't, so why would he just ask kids who ride in a car as there are kids who ride buses, or only 7th grade students, so the best answer would be something that everyone has, like homeroom.
