Answer:
6×50 +8 -7 = 301
(6 -2)(50 +25) +8 -7 = 301
50×7 -25 -8×6/2 = 301
Step-by-step explanation:
We have chosen to use 301 = 300 + 1 a couple of different ways, and 301 = 350 -49. We couldn't see a way to take advantage of the factoring 301 = 43×7.

Answer:
z = - 0.33
Step-by-step explanation:
Given that:
Mean (μ) = 73, standard deviation (σ) = 3.0
Z score is a measure in statistics to determine the number of standard deviation a value is above or below the mean of what is measured. If the value is above the mean it is positive but if it is below the mean it is negative. It is given by the equation:
To calculate z-score for Umaima's exam grade, we need to calculate the z score of 72
For x = 72, the z score is:
z = - 0.33
