Alla [95]

Answer:

Yes, he earned a Varsity letter because he played in 61% of the games.

Step-by-step explanation:

To know the percent of games he played out of the total, we can do it by dividing the games he played by the total of games and multiply this by 100% to get the percent of games he played:

$\frac{11}{18}*100%$

We solve:

0.611111*100% = 61.11%

So we know that he earned a letter because he played in 61.11% of the games, more than he needed.

A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi.

Brut [27]

Answer:

The area of this plate is $36.31\ \text{inches}^2$ .

Step-by-step explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

$C=2\pi r$

r is radius of circular shape

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{21.4}{2\times 3.14}\\\\r=3.4\ \text{inches}$

Area of this plate is given by :

$A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2$

So, the area of this plate is $36.31\ \text{inches}^2$ .

A researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment. If all the treatments had the same numbe

Vsevolod [243]

Answer:

13 participants.

Step-by-step explanation:

Given that a researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment.

i.e. degrees of treatment between groups =1

and within groups = 24

This implies that there are two groups.

For two groups to have same number of participants, since we get total of degrees of freedom =24+1 =25

Hence total items selected = 26

i.e. each group would have 13 entries

So each treatment had 13 participants.
