On saturday, a local hamburger shop sold a combined total of 340 hamburgers and cheeseburgers. the number of cheeseburgers sold was theee times the number of hamburgers sold. how many hamburgers were sold

The correct answer is 85 hamburgers were sold.

Step-by-step explanation:

Hamburgers = x

Cheeseburgers = 3x (three times the number of hamburgers)

x + 3x = 340 (combined total of hamburgers and cheeseburgers).

4x = 340

x = 340/4

x = 85

The total number of hamburgers sold at the local hamburger shop on Saturday was 85, and the total number of cheeseburgers sold was 255.

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.
