Kyle and trinity go for a walk every morning. kyle walks 2 1/4 miles. trinity walks 1 3/8 miles less than kyle. what is the total distance they walk every morning.

Step-by-step explanation:

we know that

Kyle walks 2 1/4 miles

Trinity walks 1 3/8 miles less than Kyle

Convert mixed number to an improper fraction

To find out the total distance they walk each morning, add the distance Kyle walks plus the distance Trinitry walks.

The distance Kyle walks is 9/4 miles

Find out the the distance Trinitry walks

Subtract 11/8 miles from the distance Kyle walks

Adds the distances

Convert to mixed number

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

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.
