Answer: B) Convenience Sample

Step-by-step explanation:

A convenience sample is used when pilot testing is to be done. In this case, the accounting professor wishes to know who would take a elective. Since this involves taking sample from part of population that is near at hand and can be easily taken. So it is a convenience sample.

6% of what number is 270? 4,500 450 45 4.5
Gnoma [55]

So to solve this problem, we can either do guess and check, or solve an equation.


Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.


So, to begin, let's define our unknown.

We can represent the number as "n"


So, 6 percent of "n" is equal to 270

To find a "percent" of a number, you need to multiply the number by the percentage.

So, 6 percent as a decimal is .06

This is because a percent is a fraction divided by 100 (6/100)


.6\times n=270\\\n=270\div.6\\n= 4500


The number is 4,500

Kalin walls at a streaky rate of 3 2/3 miles per hour. The beach is 4 1/4 miles from his home. How long will it take Kalin to wa
DENIUS [597]

Answer:

The time it will take Kalin will be 2h 33m

Step-by-step explanation:

First we will transform the numbers to work more comfortable

d = distance

v = velocity

v = 3 2/3 miles per hour = 3.33 mi/h

d = 4 1/4 milles = 4.25 mi

As the time it takes to go to the beach and back asks us, we have to do the distance 2 times

d = 4.25 mi * 2

d = 8.5 mi

To calculate the time it takes, we simply have to divide the distance by the velocity

t = d/v

t = 8.5 (mi) / 3.33(mi/h)

t = 2.55h

if we also want to express the minutes we can divide after the point .55 by 100 and multiply it by 60

(55/100)*60 = 33

t = 2h 33m

The time it will take Kalin will be 2h 33m
