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
Im pretty sure it's C because
w/7>3
7×(w/7)>(3)×7
w<21
To find a perpendicular line, you must flip the slope over and make it negative. So, the perpendicular slope would be -4/3. Plug the point into this slope equation and solve for the y intercept. 11 = -4/3(-5) + b. b = 13/3. So, the line would be y = -4/3(x) + 13/3
Answer:
im thinking n is 6.5 not sure wait not 6.5 its 3.5
I believe it’s b because of the way that it is
