Jacquie used an app to simulate a coin flip 400 times. It lands on heads 222 times. Based on her results, Jacquie predicts that
the expected number of times the coin will land on heads in 10,000 trials is 5,000 times. Do you think Jacquie's expected results are correct? Explain your reasoning.
Step-by-step explanation: If flipped 400 times and 222 times are heads, then there is a 55.5% chance it will be heads. If flipped 10,000 times, then there should be 5550 heads.
(-y+5x3)+(7.2y-9)=6.2y+n (-y+15)+(7.2y-9)=6.2y+n since you're adding the two parentheses, you don't need to have them there -y+15+7.2y-9=6.2y+n 7.2y-y +15-9 =6.2y+n 6.2y + 6 =6.2y+n 6.2y - 6.2y -n = -6 -n=-6 n=6
