Z-score is given by the formula:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the z-score for the data set with mean 13 and standard deviation of 2.5 will be:
z=(10-13)/2.5
z=-1.2

What is the value of m in the equation 5m − 7 = 6m + 11?<br><br> A.18<br> B. 1<br> C. −18<br> D.−1
adoni [48]
Hello there ^ _ ^

5m - 7 = 6m + 11
Solve for M
5m - 6m = 11+ 7
-m = 18
Divide both sides by -1
-m/-1 = 18/-1
m = -18

Good luck!

3x-2y=13 2x+3y=-16 are these lines parallell or perpendicular or neither
Lelechka [254]
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2

2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3

perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3. 

So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
