Jackson is 6 years older than 3 times the ag of his nephew. jackson is 30 years old. how old is his nephew?

His nephew is 8

Step-by-step explanation:

The easiest way to do this is by doing an inverse operation. To find Jackson’s age from his nephew’s age, you would need to add 6 and then times by 3. So if you take 6 from 30 (which gets you to 24) and divide that by 3, you get 8. A formula for this, where his nephew’s age is n, would be 3n+6=30

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
