Afruit stand has to decide what to charge for their produce. they decide to charge $5.30 for 1 apple and 1 orange. they also plan to charge $14 for 2 apples and 2 oranges. we put this information into a system of linear equations. can we find a unique price for an apple and an orange?

We cannot find a solution to the system of equations.

a+b = 5.30

2a + 2b = 14

Step-by-step explanation:

Let a = the price of an apple

let b = price of an orange

a+b = 5.30

2a + 2b = 14

Multiply the first equation by 2

2a+ 2b = 10.60

Subtract the second equation

2a+2b = 10.60

-2a+2b = 14

0 = -3.40

This is never true  so there is no solution

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.
