I NEED HELP Two groups separately performed an experiment by tossing a coin in the air. Group C performed 50 trials and group D performed 100 trials. Each group recorded the results in the table below: Group Heads Tails

C 31 19

D 51 49

What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? (1 point)

a

The experimental probability and the theoretical probability for group C is same.

b

The experimental probability and the theoretical probability for group D is same.

c

The experimental probability is closer to the theoretical probability for group C than group D.

d

The experimental probability is closer to the theoretical probability for group D than group C.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

none cuz there are no "following statements" regarding the question

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
