Answer:

a₁ = 2.6
aₙ = aₙ₋₁ + 1.4

Step-by-step explanation:

Given

<u>The arithmetic sequence </u>

{aₙ} = {2.6, 4, 5.4, 6.8, 8.2, ...}

We can see the common difference is d = 1.4

<u>The formula for this sequence is:</u>

a₁ = 2.6
aₙ = aₙ₋₁ + 1.4

1.15 GPA and study hours: A survey was conducted on 193 Duke University undergraduates who took an introductory statistics cours

KonstantinChe [14]

Answer:

Step-by-step explanation:

According to the exercise we can say that the explanatory variable will be hours / weeks of study.

The response variable is GPA.

We definitely found that between the variables there is a weak or fragile relationship, neither negative nor positive nor linear.

1.Observational study, since we observe that the only variables that will influence the results of the study are the observations of the students

2.No. This study is observational and its characteristics are not sufficient to conclude that studying more hours leads to obtaining a higher GPA.

Name three pairs of numbers that have 5 as their greatest common factor. Use each number only once in your answer.

GenaCL600 [577]

Answer:

Step-by-step explanation:

10,15,20. Each using 5 as the GCF

25,30,35. The biggest GCF in 25 is 5, in 30 is 6, in 35 7.

So we can't use 6 or 7 as the GCF,

But, we can use 5 as the GCF.

Same with 40, 45, 50.

The GCF of 40 is 8, for 45 is 9, and for 50 is 10.

But then again, those are not common, so 5 it is again.

And this could keep on going but watch out, it might fail! c:

Which point below is a solution to the equation y = 2x + 3?

Anastasy [175]

Answer:

C (37, 77)

Step-by-step explanation:

<h3>Option A:</h3>

$291=2(145)+3\\\\291=290+3\\\\\boxed{291\neq 293}$

Option A is not a solution.

<h3>Option B:</h3>

$163=2(78)+3\\\\163=156+3\\\\\boxed{163\neq 159}$

Option B is not a solution.

<h3>Option C:</h3>

$77=2(37)+3\\\\77=74+3\\\\\boxed{77=77}$

Option C is a solution.

Hope this helps.
