-10/5+2(7-9)^2
Oksana_A [137]
Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.


I hope that helps.

General formula for a simple linear regression :

y = ab + c

Where ;

y = predicted variable ; a = slope / gradient

b = predictor / independent variable ; c = intercept

From the result obtained from the calculator :

y = -0.01246X + 74.65552

Correlation Coefficient is used to measure the strength of relationship between linear variables.

The regression Coefficient obtained is - 0.20

This shows that there is a weak negative correlation between the age at auction and the price at which painting is sold. This is because the negative sign means that value of y decreases as x increases or vice versa, however, due to a correlation vale which is closer to 0 than 1 or - 1, we can conclude that the negative relationship between the variables is weak.

Which table might represent ava's line ?
Serjik [45]

Answer:

The correct option is 3.

Step-by-step explanation:

To find the slope of a line Ava wrote the expression

m=\frac{4-2}{3-1}       ..... (1)

The formula to find the slope is

m=\frac{y_2-y_1}{x_2-x_1}            .... (2)

On comparing (1) and (2), we get

x_1=1, y_1=2

x_2=3, y_2=4

It means the value of y is 2 at x=1 and the value of y is 4 at x=3.

Therefore table 3 represents the Ava's line and option 3 is correct.
