70 adults and 100 children attended the carnival.
Step-by-step explanation:
Given,
Cost of each adult ticket = $10
Cost of each child ticket = $5
Total tickets sold = 170
Total revenue generated = $1200
Let,
Number of adults = x
Number of children = y
According to given statement;
x+y=170 Eqn 1
10x+5y=1200 Eqn 2
Multiplying Eqn 1 by 10
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 5
Putting y=100 in Eqn 1
70 adults and 100 children attended the carnival.

Step-by-step explanation:
in 4 straight games ?
game 1 has a probability of 0.9 (= 90%).
for 2 games we have the probability of the first game, and now based on this we have to apply the probability of the second game.
in other words, the desired event has to happen in the first game AND then also in the second game.
since both probabilities are smaller than 1 (0.9), the total probability for 2 games must be less than the probability for 1 isolated game.
to combine such probabilities as "and" events, we have to multiply these probabilities.
so, the probability for 2 games is
0.9 × 0.9 = 0.9² = 0.81
and in the same way we get the probability to score the first goal in 4 games in a row :
0.9⁴ = 0.6561
Answer
yes it is correct
