A car travels at a constant speed of 20m/s.

Mathematics

Bad White [126]2 years ago

Answer:

Step-by-step explanation:

Let's convert either m/s to km/s, or km to meters.

I'll convert km to meters and solve.

8 minutes and 20 seconds

There are 1,000 meters/kilometer.  We can write that as a conversion factor:  (1000m/km)

(10km)(1000m/km) = 10,000 meters

At 20m/s, we see that:  (10,000m)/(20 m/s) = 500 seconds

(1 minute/60 seconds)

(500s)*(1m/60s) = 8 1/3 minutes, or 8 minutes and 20 seconds

To compare the production techniques used by foreign and local firms in Brazil, a random sample of 80 foreign firms and a random
alina1380 [7]

Answer:

An independent sample.

Step-by-step explanation:

In this scenario, to compare the production techniques used by foreign and local firms in Brazil, a random sample of 80 foreign firms and a random sample of 80 local firms are selected. We can safely conclude that this study uses an independent sample design.

An independent sample design can be defined as a research method that usually involves the use of multiple experimental groups (two or more). The samples or participants are only in one group and as such each group has no relationship with the other. This simply means that, the samples in a particular group is having no relationship with the other samples in another group.

Ultimately this implies, each samples are independent and satisfies only one condition of the independent sample design during the experiment to compare the production technique used by foreign and local firms in Brazil.

<em>Hence, the researcher would use only two variables or conditions: a random sample of 80 foreign firms and a random sample of 80 local firms are selected.</em>

♡ The Explanation/Step-By-Step ♡

- 6/100 + 5/100 + 80/100 + 9/100

Apply the fraction rule! --> a/c + b/c = a + b over c

6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100

Add the numbers: 6 + 5 + 80 + 9 = 100!

= 100/100 Apply the fraction rule! a/a = 1

a/a = 1 = 100/100 = 1
