Answer:
Tom can either take 24 kicks and make 16 goals or 30 kicks and make 20 goals.
Step-by-step explanation:
Andre made 4 goals out of 6 kicks.
Tom wants to take more than 20 kicks and to make an equivalent fraction to Andre.
<u>Possibility 1:</u>
Let Tom makes 24 kicks.
To get 24, we need to multiply the denominator of Andre's fraction by 4.
So, 
Therefore, Tom can take 24 kicks and make 16 goals.
<u>Possibility 2:</u>
Let Tom makes 30 kicks.
To get 30, we need to multiply the denominator of Andre's fraction by 5.
So, 
Therefore, Tom can take 30 kicks and make 20 goals.
Answer:
Option C. No, because the two populations from which the samples are selected do not appear to have equal variances.
Step-by-step explanation:
The variance measures how far a set of (random) numbers are spread out from their average value.
The fact that the younger adults show diversity in their brain activity while the older adults produce similar activities show that there are no equal variances in the two populations from which the samples are selected.
Therefore it would not be valid for Dr. Park to use the independent-measures t-test to test whether the brain activity of younger adults is different from that of older adults during a visual recognition task

Answer:
Joe is 14.
Martha is 28.
Step-by-step explanation:
Use the variables and information from the question to make equations.
If Joe's age is half Martha's:
(1/2)m = j OR 2j = m
If their ages combined is 42:
m + j = 42
We can substitute the equation m=2j into equation m + j = 42, replacing "m".
m + j = 42 Substitute m for 2j
2j + j = 42 Combine like terms, terms with same varables
3j = 42 Divide both sides by 3 to isolate j
j = 14 Joe's age
Since j = 14, we can substitute it into equation m=2j to find "m".
m = 2j Substitute j for 14
m = 2(14) Simplify
m = 28 Martha's age
Therefore Joe is 14 and Martha is 28.
