Please answer the equation part ASAP. I’ve tried my best to work it out and it still hasn’t worked and I ran out of tries, so this is my only hope. Thank you in advance. Stay safe out here and be aware of your surroundings ‼️‼️

Equation: m: number of miles she still has to run; m+6+8+6=28

Solution: m=8

Step-by-step explanation:

Sum of miles she has to run total = 28

Monday: ran 6 miles

Tuesday: ran 8 miles

Wednesday ran: 6 miles

Sum of miles ran: 20

Since you're trying to figure out how many miles she has left, subtract 20 from  28:

28-20=8

She has 8 miles left to run

The equation is: 6+8+6+m=28; m=number of miles left

step-by-step explanation:

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.
