Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
Answer:
The average age of the students at the school is 16.4 years.
Step-by-step explanation:
To find the average age of the students at the school, we multiply each age by it's percentage.
We have that:
7% of the students are 14
22% of the students are 15
24% of the students are 16
23% of the students are 17
19% of the students are 18
The rest is 19
The rest is?
100-(7+22+24+23+19) = 100 - 95 = 5
So 5% of the students are 19
Find the average age of the students at Thomas Jefferson High School.
![A = 0.07*14 + 0.22*15 + 0.24*16 + 0.23*17 + 0.19*18 + 0.05*19 = 16.4](https://tex.z-dn.net/?f=A%20%3D%200.07%2A14%20%2B%200.22%2A15%20%2B%200.24%2A16%20%2B%200.23%2A17%20%2B%200.19%2A18%20%2B%200.05%2A19%20%3D%2016.4)
The average age of the students at the school is 16.4 years.
