1/3 of m to the fifth power equals 12

Step-by-step explanation:

1/3 m ^5 = 12                  Multiply both sides by 3

3(1/3) m^5 = 12 * 3

m^5 = 36

Now you have to be using a calculator capable of getting an answer that is a 1/5 power.

The key you need is either x^y or y^x or ^ All scientific calculators have one of these.

(m^5)^(1/5) = 36^(1/5)

m = 2.048 This has been rounded to the one thousandth place.

You should check this

2.048 * 2.048 * 2.048 * 2.048 * 2.048 = 36.029 which is very close considering how this was founded.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

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.
