Answer:

No

Step-by-step explanation:

A matched pair design is used when we have two different observation about a certain experiment for each subject such that there is a natural pairing between the two population.

In the scenario described above, we have 20 subjects of which 10 are boys and 10 are girls.

Matching boys and girls having similar numbers does not depict natural pairing and thus using a matched paired test would be inappropriate. The test to use for such experiment is the two population t test.

The length of the midsegment of a triangle is always half the length of the side it is parallel to true or false
Vladimir [108]
True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.

This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.

On an average day, a garden snail can travel about 0.05 mile. The snail travels 0.2 times as far as the average distance on day
daser333 [38]

Answer: 0.04 miles

 

SOLUTION

 

Given,

Average daily distance of a garden = 0.05 mile.

 

Distance traveled on day 1 = 0.2 times as far as the average distance

= 0.2 x 0.05 miles

= 0.01 miles

 

Distance traveled on day 2 = 0.6 times as far as the average distance

= 0.6 x 0.05 miles

= 0.03 miles

 

Total distance traveled in two days

= Distance traveled on day 1 + Distance traveled on day 2

= 0.01 miles + 0.03 miles

= 0.04 miles

penny reads 10 pages in 1/3 of an hour. What is the unit rate for pages per​ hour? For hours per​ page?
Korolek [52]

Penny reads 14 pages in 1/3 hour.
In order for us to know the rate of penny, the number of hours per page, we need to do ratio and proportion.

14 : 1/3 = X : 1
1/3X = 14
X = 42

So there are 42 pages Penny can read in 1 hour.
