Explain how you can tell whether a point lies on either the x- or y- axis bt looking at its coordinates

1 answer:

7 0

If its on the left of the x=0 line then the x coordinates are negative and if the coordinates are to the right of the line x=0 they are positive and for y coordinates it the point is above the line y=0 its positive and if its below that line its negative

Answer:

I know this is late, but for<em> future people</em>:

I believe the answer is <u>2b+3c</u>.

Step-by-step explanation:

I'm pretty sure all you have to do is combine like terms.

I'm also taking the test at the moment.

Can someone help its math :)

belka [17]

Answer:

m<F = 53

Step-by-step explanation:

Exterior angles thm:

5x - 10 + 3x + 14 = 100

8x + 4 = 100

8x = 104

x = 13

m<F:

3x + 14

3(13) + 14

39 + 14

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was us

ExtremeBDS [4]

Answer:

There is a linear correlation between chest size and weight,0.8482

Step-by-step explanation:

Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.

the value of the linear correlation coefficient is r = 0.921.

i.e. there is a strong positive correlation from the value of r.

$H_0: r=0\\H_1: r\neq 0$

(Two tailed test at 5% level for correlation coefficient)

Test statistic t = $\frac{r\sqrt{n-2 } }{\sqrt{1-r^2}} \\=5.791$

p value <0.00001

Since p is less than 0.05 we reject H0

a) There is a linear correlation between chest size andweight

b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
