Answer is D - No, because the probability of success is different for each trial.
Step-by-step explanation:
As given-
A state lottery randomly chooses 7 balls numbered from 1 through 45 without replacement.
You choose 7 numbers and purchase a lottery ticket.
Determine whether this experiment is binomial.
Answer is D - No, because the probability of success is different for each trial.
Answer:
x = -2
y = 10
Step-by-step explanation:
(0.3 + 0.7) x + (0.4 - 0.8) y = 0.8 - 6.8
x - 0.4 y = -6 → x = 0.4 y - 6
0.3 ( 0.4 y - 6) + 0.4 y = 0.8 → 0.12y +0.4y - 1.8 = 0.8
→ 0.52 y = 2.6 → y = 2.6/0.52 = 10
x - 0.4(10) = -6 → x = -2
