The residual points include the difference between the value in Irwin's dataset and the predicted values

<h3>How to plot the residuals?</h3>

The residual is calculated using:

Residual = Actual points - Predicted points

The actual points are:

(1,43), (3, 36), (5,22), (6, 25), (8,14)

The predicted points are:

(1,44), (3, 35), (5,26), (6, 22), (8,13)

Using the residual formula above, we have the residuals to be:

(x,y) = (1,-1), (3, 1), (5,-4), (6, 3), (8,1)

See attachment for the residual plot

Probability of rolling factors of 20

Marizza181 [45]

If you are rolling a single six sided die numbered 1-6, you find that only 1,2,4, and 5 are factors of 20. Now the theoretical probability of an event is the ratio comparing the number of desired outcomes to the total outcomes possible.

In this case: we have 4 desired outcomes out of a total 6 outcomes possible with a single roll the die.. therefore, the probability you seek is $\frac{4}{6} = \frac{2}{3}$ or approximately 67%.

How many subsets are there of the set N = {1, 42, 65, 12, 31, 27}?

lutik1710 [3]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{64}}}}}$

Step-by-step explanation:

If ' n ' is the cardinal number of a set, the number of subsets of a given set can be obtained by using the formula 2ⁿ

Given,

N = { 1 , 42 , 65 , 12 , 31 , 27 }

where n ( total number of elements ) = 6

So, the number of possible subsets of set N :

= 2ⁿ

= 2⁶

= 2 × 2 × 2 × 2 × 2 × 2

= 64

Answer:

I got x1 =0 x2=220

Step-by-step explanation:

y=- 00.1x (x-220)

-0.01x (x-220)=0

- 1/100 x(x-220)=0

x (x-220)=0

x=0

x-220=0

Answer x=0 and x=220

How to convert 2/25 in to a decimal and then into a percent

Vikentia [17]

To convert 2/25 into a decimal, u simply divide 2/25 and the answer would be 0.08
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
