Use the midpoint formula to find the midpoint between H(3, 9) and J(9, -2).

TiliK225 [7]

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: $(\frac{x_{1}+x_{2}} {2},\frac{y_{1}+ y_{2}} {2})$ .

With the formula above, we can substitute the given points into the equation, and simplify.

$(\frac{3 +9}{2}, \frac{9+(-2)}{2}) = (\frac{12}{2}, \frac{7}{2}) = (6, 3.5)$

Therefore, the midpoint between points H and J is choice D, (6, 3.5).

Which sentence correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14

denis-greek [22]

Answer:

Option (c) is correct.

68% of the data points lie between 10 and 18.

Step-by-step explanation:

Given : a normal distribution with a standard deviation of 4 and a mean of 14

We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.

Since, given 68% data.

We know mean of data lies in middle.

And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.

So, 68% of data lies

mean - standard deviation = 14 - 4 = 10

mean + standard deviation = 14 + 4 = 18

So, 68% of the data points lie between 10 and 18.

Hi There!

----------------------------------------------

Part A:

Slope Intercept Form: y = mx + b

m = slope (slope = $\frac{y2 - y1}{x2 - x1}$ )

b = y intercept

$m=\frac{4 - 6}{(-2)- (-6)} = \frac{-2}{4} = \frac{-1}{2}$

b = 3

Answer: y = -1/2x + 3

----------------------------------------------

Part B:

Just substitue f(x) for y.

Function Notation = f(x) -1/2 + 3

----------------------------------------------

Part C:

This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.

----------------------------------------------

Hope This Helps :)
