Student Council earned $26 selling
bottled water, $32 selling oranges, and
$28 selling energy bars. If all items cost
the same, what is the greatest possible
price per item?
A $2
C $7
B $4
D $8

Option A

The greatest possible  price per item is $ 2

Solution:

Given that,

Student Council earned $26 selling  bottled water

$32 selling oranges

$28 selling energy bars

If all items cost  the same, what is the greatest possible  price per item

Which means, we have to find the greatest common factor of 26, 32 , 28

Find GCF of 26, 32 , 28

The factors of 26 are: 1, 2, 13, 26

The factors of 28 are: 1, 2, 4, 7, 14, 28

The factors of 32 are: 1, 2, 4, 8, 16, 32

Then the greatest common factor is 2

Thus the greatest possible  price per item is $ 2

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.

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
