Answer:

i)  y∝x  => y = kx and k = 2.5

ii) When x = 7, y is 17.5

Step-by-step explanation:

If y is directly proportional to x then according to the question

y∝x  which means y =kx where k is any constant

From the above example

8y=20x comparing it with y = kx

y =  (20/8)x

y = 2.5x

Here k = 2.5

i) y∝x  =>  y =2.5x

ii) if x=7 then y = ?

From above

y=2.5x

Put x = 7

y = 2.5 x 7

y = 17.5

Answers

Answer:

55

Step-by-step explanation:

The probability of picking a can of carrots is 1/10.

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

Mrs. Phillips has some cans of peas, beans, corn, and carrots without labels.

When a can is chosen randomly, the probability of picking a can of peas is 1/10, a can of beans is 3/10, and a can of corn is 1/2.

The probability of picking a can of carrots,

= 1 - 1/10 + 3/10 + 1/2

= 1/10

Therefore, 1/10 is the probability.

Part A- About 1/2(half) of 350 would be reasonable since there is only two options for all 350 flips.

Part B- Theoretical probability, since an experiment has yet to be conducted it can't be experimental.
