Aset of cards contains the numbers 1 through 20. mathieu chooses a card at random, records the number of the card, and then returns the card to the set. he conducts 200 trials of this event. based on the theoretical probability, how many times can mathieu expect to choose a multiple of 5?

There are 40 times that Mathieu would expect to choose a multiple of 5.

Step-by-step explanation:

Since we have given that

Number written on a set of cards from 1 to 20

We require the number which is a multiple of 5.

So, the set of number which is a multiple of 5 is given by

{5, 10, 15, 20}

So, probability of getting a number which is a multiple of 5 is given by

According to question, he conducts 200 trials of this event.

So, Number of times Mathieu can expert to choose a multiple of 5 is given by

Hence, there are 40 times that Mathieu would expect to choose a multiple of 5.

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
