Which statement is true about the graphs of the two lines and ?

1 answer:

5 0

The true statement about the graphs of these two lines are The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other. First option is right

<h3>How to solve for the lines</h3>

The equation of the graph is in its intercept form. This is given as y = mx + b. m is the slope while be is the intercept.

The slopes of the lines have \been given as -8 and 1/8. These numbers are negative reciprocals when they are multiplied,

-8 * 1/8

= -1

Hence the first statement is right.

Answer: The mean and standard deviation are 567.2 and 89.88 resp.

Step-by-step explanation:

Since we have given that

For 370 parts per million = 7% = 0.07

For 440 parts per million = 10% = 0.10

For 550 parts per million = 49% = 0.49

For 670 parts per million = 34% = 0.34

So, Mean of the carbon dioxide atmosphere for these trees would be

$E[x]=370\times 0.07+440\times 0.1+550\times 0.49+670\times 0.34=567.2$

And

$E[x^2]=370^2\times 0.07+440^2\times 0.1+550^2\times 0.49+670^2\times 0.34=329794$

So, Variance would be

$Var\ x=E[x^2]-E[x]^2=329794-567.2^2=8078.16$

So, the standard deviation would be

$\sigma=\sqrt{8078.16}=89.88$

Hence, the mean and standard deviation are 567.2 and 89.88 resp.

Note that the right triangles with sides equal to 5, 12, 13 and 9, 12, 13 both have a side equal to 12. using this fact find the

There is a mistake 9,12,13 is not a right triangle. but 9,12,15 is. IF you use this triangle instead, then the area of the 13,14,15 triangle is the sum of the area of the other two triangles.

kondaur [170]

Answer:

Step-by-step explanation:

a³+b³=(a+b)(a²-ab+b²)

x³+216=x³+6³=(x+6)(x²-6x+6²)=(x+6)(x²-6x+36)

How many sides does a regular polygon have, if each exterior angle measures 60?

DaniilM [7]

In a regular polygon, each exterior angle equals each central angle.
central angle = 360 / #sides
#sides = 360 / central angle
#sides = 360 / 60
#sides = 6
