Liula [17]
From the data shown in the scater plots, the points are scattered apart which means that r is not close to 1.

Also the data points increase to the right which means that r is positive.

Therefore, the estimate for r in the data shown in the scatter plot is 0.55

Help please i dont know this thank you<33
jok3333 [9.3K]

Answer:

  • 42
  • 35
  • 16

Step-by-step explanation:

Put the value where the variable is and do the arithmetic. It can save some steps to simplify the expression first.

  35 -c³ +8 = 43 -c³

<u>c = 1</u>

  43 - 1³ = 43 -1 = 42

<u>c = 2</u>

  43 - 2³ = 43 -8 = 35

<u>c = 3</u>

  43 -3³ = 43 -27 = 16

The values that go in the blanks are 42, 35, 16.

_____

<em>Additional comment</em>

It does not take long to learn how to use a spreadsheet for evaluating the same formula with a number of different values of the variable(s). Graphing calculators can do this, too. It is always appropriate to use the right tool for the job.

Familiarity with multiplication and addition facts is a very good place to start. It is also useful to memorize the squares and cubes of small integers. The latter are needed here.

Tammy will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs 0.70 per mil
tensa zangetsu [6.8K]
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
