Name the property the equation illustrates.

8.2 + (–8.2) = 0

The equation illustrates inverse property of addition.

Explanation:

The equation is

The equation illustrates inverse property of addition.

The inverse property of addition states that the sum of a negative number and the same number which is positive will always be equal to zero.

Thus, the number added to its opposite sign results in zero.

In other words, the purpose of inverse property of addition is to get the result zero after addition.

Hence, the equation illustrates inverse property of addition.

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.
