Calculate the distance between the points C=(-7, 7) and M=(-2, 3) in the coordinate plane.
pishuonlain [190]

Answer:

d = Sqrt 41 = 6.4

Step-by-step explanation:

d = sqrt [(x-x)^2 + (y-y)^2]

d = sqrt [(-7 - - 2)^2 + (7-3)^2]

d = sqrt[(-7+2)^2 + (4)^2]

d = sqrt [(-5)^2 + (4)^2]

d= sqrt (25 + 16)

d = sqrt 41 = 6.4

ella [17]

Answer:

The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the​ standard error of the mean . The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the standard distribution of the sample.

Step-by-step explanation:

The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.

I need help with this question! Thank you! :))<br> (question info below)
Stolb23 [73]

Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]

To find the equation's y-intercepts, you can rearrange the variables, and isolate/get y by itself

#1

cx + ay = b     Subtract cx on both sides

ay = b - cx        Divide a on both sides

y=\frac{b}{a}-\frac{c}{a}x    (0, \frac{b}{a}) is your answer

Do the same for the rest, and you should get:

#2 (0, \frac{a}{b})

#3 (0, \frac{c}{b})

#4 (0, \frac{c}{a})
