I believe the X-coordinate of the midpoint would be (0.5,-0.5)
25%. With a 50% chance of it landing heads the first time, you need to multiply it by the percentage that you have that it will land on heads again, which is 50. 50% of 50 is 25, and then having it land on either heads or tails for the third time is guaranteed, so multiply that probability (100%) by the previous 25% which ends up being simply 25%
Answer:
Step-by-step explanation:
A. "a pair of pants originally priced at &40$ and a shirt originally priced at $45. He pays $55"—correct
(1-0.30)$40 + (1-0.40)$45 = $55
B. "Mary buys two shirts originally priced at $25. She will pay $35."—incorrect
2×(1-0.40)$25 = $30
C. "a pack of four shirts on sale for $37.80. The pack of shirts was originally priced at $54"—incorrect
(1-0.40)$54 = $32.40
D. "a pair of pants for sale price of $40.60. The pair of pants was originally priced at $58."—correct
(1-0.30)$58 = $40.60
