Step-by-step explanation:
<u>Equation Plan A</u>
<u>Equation Plan B</u>
<u>Equating them</u>
- 40x + 860 = 100x + 200
- 60x = 660
- x = 11
- The plans will pay the same at 11 correct questions.
<u>Solving for y using x = 11</u>
- y = 100(11) + 200
- y = 1100 + 200
- y = 2300
- The amount they'll pay at that number of questions is $2,300
<u>Comparing both plans when x = 13</u>
- Plan A : 40(13) + 860 = 520 + 860 = $1,380
- Plan B : 100(13) + 200 = 1300 + 200 = $1,500
- As Plan B pays more, that is the plan you should choose
B) the slope of a line is always positive, no matter which way the line is positioned.
Answer:
0.0178
Step-by-step explanation:
For computation of probability that all fourteen bets lose first we need to find out the Probability of losing in 1 bet is shown below:-
Probability of losing in 1 bet = 1 - P(winning)
= 1 - 0.25
= 0.75
With the help of probability of losing in 1 bet we can find out the Probability of losing in 8 bets which is here below:-
= Probability of losing in 1 bet ^ Number of loosing bets
= 0.75 ^ 14
= 0.017817948
or
= 0.0178
Therefore for computing the probability that all fourteen bets lose we simply applied the above formula.
