Linear would be if the change between the x and y's are similar:
Function A:
9.252 - 6.083 = 3.169
14.07 - 9.252 = 4.818
21.4 - 14.07 = 7.33
The differences are different so it is exponential.
Function B
14-7 = 7
21 - 14 = 7
28 - 21 = 7
The differences are the same so this is linear.
Function C
4-16 = -12
1-4 = -3
0.25 - 1 = -0.75
The differences are different so this is exponential.
Answer: 12
<u>Step-by-step explanation:</u>
The LCM of 48 and 28 is 336
It would take 336 ÷ 28 = 12 revolutions of gear B
and 336 ÷ 48 = 7 revolutions of gear A
to match up the arrows.
This is good information, but the question part is missing. Put the question in the comments and I'll try my best to help!
Answer:
Conclusion : People ≠ 20% don't know about their credit score.
Step-by-step explanation:
Hypothesis is testing a statement for its statistical significance.
Null Hypothesis (H0) implies 'no difference from tested value', Alternate hypothesis (H1) implies 'significant difference from tested value'
Let % of people knowing their credit score = CS
H0 : CS = 20
H1 : CS ≠ 20
If the null hypothesis is rejected, it implies that we reject the claim that CS i.e '% of americans knowing their credit score = 20%'. So, the alternate hypothesis is accepted, i.e we conclude that '% americans knowing their credit score ≠ 20%'.
