120 students were provided a provided a choice of breakfast. They had three choices: fruit, cereal, and/or yogurt. 53 students had cereal, 47 students had yogurt, and 47 students had fruit. Also, 38 students had only cereal, 12 students had yogurt and fruit but no cereal, 27 students had only fruit, and 25 students had only yogurt. Find the number of students that chose not to have breakfast.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

i believe that the answer is

b. y-1=-2(x-4)

hope this !
