How to do the problem

trapecia [35]

Step-by-step explanation:

$g(0.5) = 2 \\ \\ h(x) = g(x).f(x) \\ \therefore \: h(2) = g(2).f(2) \\ \therefore \: h(2) = 5 \times 2\\ \therefore \: h(2) = 10\\ \\ \\ j(x) = g(x) - f(x) \\ \therefore \: j(4) = g(4) - f(4) \\ \therefore \: j(4) = 9 - 8\\ \therefore \: j(4) = 1\\ \\ \\$

Sedaia [141]

Answer:

Airspeed in still air: 140 mph

Step-by-step explanation:

Let s represent the speed in still air. Recognize that the distance traveled is the same in either direction.

Also note that SF is north of LA.

Distance to SF from LA = Distance to LA from SF

(s-20)(mph)(4 hr) = (s+20)(mph)(3 hr)

Then:

4s - 80 = 3s + 60 => s = 60 + 80 + 140 (mph)

The airspeed of the plane was 140 mph in still air. With a tail wind, the plane is faster; with a headwind, slower.

STatiana [176]

Answer: $H_0: p=0.74\\\\ H_a:p$

Step-by-step explanation:

Let p be the population proportion for the graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.

Given : Tristan is an administrator for a private nonprofit college and read a surprising statistic that 74% of graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.

i.e. $p=0.74$

He believes that percentage is high and claims that the proportion of graduates at his college is less than the regional rate.

i.e. $p$

Since, the null hypothesis is a statement which always takes equal sign or generally shows " no difference " where as alternative hypothesis takes unequal signs.

Then, the null and alternative hypotheses for this hypothesis test :-

$H_0: p=0.74\\\\ H_a:p$
