Anderson earns $20 per month for completing chores around the house. Each month, the amount Anderson earns increases by $0.50. W

Eva8 [605]

Mathematical equation -

20 + 0.50x = ?

X is the placeholder which in this case equals months

But in this case you want to look for form month three to month 18 (which is 15 months) so three months went by so the equation is

$61.50(being the three months already)

(20+(0.50*15))+61.50=?

Descending order of 2.061,0.66,2.612,6.21,2.62

bonufazy [111]

Answer:

Step-by-step explanation:

Descending order:

6.21 ; 2.62 ; 2.612 ; 2.061 ; 0.66

First see the whole number. write the number with biggest whole number.

6.21

2) Then three numbers have 2 . So, now compare the tenth place.

Two numbers have same place value 2.62 and 2.612.

Compare the hundredth place value in these two numbers.

So, 2.62

3) 2.612

4) 2.061

5) 0.66 is the smallest

Work out the circumference of this circle.

worty [1.4K]

<h3>given:</h3>

diameter= 13 cm

the circumference of the given circle.

<h3>solution:</h3>

$c = \pi \: d$

$c = 3.142 \times \: d$

$c = 3.142 \times 13$

$c = 40.846 \: cm$

hence, the circumference of the given circle is 40.846 cm

Kiley gathered the data in the table. She found the approximate line of best fit to be y = 1.6x – 4. A 2-column table with 5 row

Dimas [21]

Answer:

The residual value is -1.8 when x = 3

Step-by-step explanation:

We are given the following table

x | y

0 | -3

2 | -1

3 | -1

5 | 5

6 | 6

Residual value:

A residual value basically shows the position of a data point with respect to the line of best fit.

The residual value is calculated as,

Residual value = Observed value - Predicted value

Where observed values are already given in the question and the predicted values are calculated by using the equation of line of best fit.

$y = 1.6x - 4$

When we substitute x = 3 in the above equation then we would get the predicted value.

$y = 1.6x - 4 \\\\y = 1.6(3) - 4 \\\\y = 4.8 - 4 \\\\y = 0.8$

So the predicted value is 0.8

From the given table, the observed value corresponding to x = 3 is -1

So the residual value is,

Residual value = Observed value - Predicted value

Residual value = -1 - 0.8

Residual value = -1.8

Therefore, the residual value is -1.8 when x = 3

Note: A residual value closer to 0 is desired which means that the regression line best fits the data.
