Answer:
n = 6
Step-by-step explanation:
2 = ![\frac{n}{3}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B3%7D)
multiply both sides by 3
=> n = 6
1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5
