Answer:

Top right

Step-by-step explanation:

1). Top left graph shows the points forming a straight line when we join them.

It's a linear graph.

2). Top right graph having a curve represents an exponential graph.

3). Bottom left graph is having a straight line which represents a linear graph.

4). Bottom right graph shows a straight line which represents a linear graph.

Therefore, Graph in the top right doesn't belong the group.

Line segment JM has endpoints with coordinates -2 and 14 on a number line. Points K and L are on segment JM. K has a coordinate

Murljashka [212]

Answer:

B. $\frac{25}{64}$

Step-by-step explanation:

Please find the attachment.

We have been given that line segment JM has endpoints with coordinates -2 and 14 on a number line. Points K and L are on segment JM. K has a coordinate of 2 and point L has a coordinate of 8.

The probability that the first point is positioned on JL would be $\frac{10}{16}$ as there are total 10 points on JL as L is at point 8 and J is at point -2 so (8--2=8+2=10). Total number of points on the number line JM is (14--2=14+2=16)

The probability that second point is not placed on KL would be:

$P(\text{The point is not on KL)}=1-\text{probability that point is on KL}$

$P(\text{The point is not on KL)}=1-\frac{\text{Total points on KL}}{\text{Total points on JM}}$

$P(\text{The point is not on KL)}=1-\frac{(8-2)}{16}$

$P(\text{The point is not on KL)}=1-\frac{6}{16}$

$P(\text{The point is not on KL)}=\frac{16-6}{16}$

$P(\text{The point is not on KL)}=\frac{10}{16}$

$\text{The probability of getting 1st point on Jl and second point is not on KL}=\frac{10}{16}\times \frac{10}{16}$

$\text{The probability of getting 1st point on Jl and second point is not on KL}=\frac{5}{8}\times \frac{5}{8}$

$\text{The probability of getting 1st point on Jl and second point is not on KL}=\frac{25}{64}$

Therefore, our desired probability will $\frac{25}{64}$ and option B is the correct choice.

Three consecutive integers have a sum of 255 find the integers

GaryK [48]

Answer:

Step-by-step explanation:

Givens

Let the smallest integer = x - 1 (You'll see why in a moment).

Let the middle integer = x

Let the largest ingeger = x + 1

Equation

x - 1 + x + x + 1 = 255

Solution

Combine like terms on the left.

3x - 1 + 1 = 255

3x = 255 Divide by 3

3x/3 = 255/3

x = 85

So the smallest number is 84

The middle number is 85

The largest number is <u> 86</u>

Total 255

Do you see why I made the smallest number x - 1?

It is because the -1 and the plus 1 cancel out.

Please realize the question says consecutive integers. It does not say consecutive odd or consecutive even integers.
