Answer:
1 1/4 hours
Step-by-step explanation:
.75/.6=x/1
cross multiply
.75=.6x
divide by .6
x=1.25 hours
<span>Karen got an average of 0.444 hits out of 45 bats.
We need to find the number of hits did Karen got.
=> 45 bats all in all
=> 0.444 average hits
x = how many hit did she get
Now, let’s multiply the total bats to Karen’s average hit:
=> 45 x 0.444 …. (repeating decimals)
=> 20
Therefore, Karen hit 20 times out of 45 bats
Let’s check our answer:
=> 20 / 45
=> 0.44444…. (repeating decimals)

Step-by-step explanation:
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.
