Nicki was told to find three consecutive odd integers whose rum is 53. What is the right equation?

The option D) x + x+2 + x+4 = 53 represents the exact equation of sum of three consecutive odd integers which is equal to 53.

Step-by-step explanation:

The sum of the three consecutive odd integers = 53

To frame the equation :

Assume the first odd integer as 'x'. In this case, (x=1)

Therefore, the second consecutive odd integer is x+2.

Therefore, the third consecutive odd integer is x+4.

This means that, the sum of any three consecutive odd integers are given as x + x+2 + x+4.

Given that,

Sum of the three consecutive odd integers is 53.

The first odd integer + second odd integer + third odd integer = 53

x + x+2 + x+4 = 53.

The option D) x + x+2 + x+4 = 53 represents the exact equation of sum of three consecutive odd integers which is equal to 53.

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.
