Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify t

he null and alternative​ hypotheses, test​ statistic, critical​ value(s), and state the final conclusion that addresses the original claim. A simple random sample of pages from a dictionary is obtained. Listed below are the numbers of words defined on those pages. Given that this dictionary has 1459 pages with defined​ words, the claim that there are more than​ 70,000 defined words is the same as the claim that the mean number of defined words on a page is greater than 48.0. Use a 0.01 level significance level to test this claim. What does the result suggest about the claim that there are more than​ 70,000 defined words in the​ dictionary?

If it takes B hours to walk a certain distance at the rate of 3 miles per hour, the number of hours it takes to return the same
natita [175]

Answer:

It will take 0.75B hours for the return leg

Step-by-step explanation:

Here, given that the first leg of the trip was for B hours at 3 miles per hour , we want to calculate the number of hours the return leg will take at 4 miles per hour given that it is the same distance.

Mathematically, we know that ;

Distance = speed * time

So the distance taken on the first leg of the trip would be;

Distance = 3 miles per hour * B hours = 3B miles

Now, this distance was traveled on the return leg also.

This means that the time taken here will be;

Time on return leg = distance/speed = 3B/4 = 0.75B hours

What number should both sides of the following equation be multiplied by to solve for g? g divided by 2 = 4
77julia77 [94]

Answer: Multiply both sides by 2.

Step-by-step explanation:

g divided by 2  is equal to 4 .

We could represent that with the equation :

\frac{g}{2} = 4     To solve for g  in this case multiply both sides by 2.

\frac{g}{2} * 2 = 4(2)     2 cancels out on the left side so we will be left with g. On the right side will be left with 8  after multiplying.

g = 8

rewona [7]

Answer:

Hello! So your answer would be 90 degrees!

Step-by-step explanation:

So the equation would be

x + 50 + 40 = 180.

50 + 40 = 90

180 - 90 = 90!

So basically y and x are both 90
