Answer:
mean = 34
Step-by-step explanation:
the mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] = [tex]\frac{20+28+30+38+39+40+43}{7}[/tex] = [tex]\frac{238}{7}[/tex] = 34
Answer: 34
Step-by-step explanation:
Mean is the same as average, and to find average you add all the numbers up and divide by the amount of numbers present. So, if you add all of them up, you get 238. Then, you'll divide by 7, since there are 7 numbers. And that will get you 34.
