Last year you mowed and shoveled snow for 10 households. you earn $200 per household mowing for the entire season and $180 per household shoveling for the entire season. you earned a total of $1,880 last year. write and solve an algebraic model to determine the number of households you mow and shovel for.

if im mistaken 200 x 10 = 2000 divided by 180 = 11.1111111

which equals 11.11 or 11.1

hope this helped!

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.
