The probability of losing first 5 wagers is (0.6)⁵
<u>Explanation:</u>
The probability of winning = 0.4
The probability of losing = 1 - 0.4
= 0.6
Probability of losing their first 5 wagers = ?
Probability of losing first 5 wagers = (0.6)⁵
Therefore, the probability of losing first 5 wagers is (0.6)⁵
Answer:
1808 people
Step-by-step explanation:
Find 1% by dividing by 100.
1600/100=16

Answer:
13120
Step-by-step explanation:
The sum of terms of a geometric series is ...
Sn = a1·(r^n -1)/(r -1)
You have n=8, a1=4, r=3, so the sum is ...
S8 = 4·(3^8 -1)/(3 -1) = 2(3^8 -1) = 13,120
Ok... so this question can be solved by using simultaneous equations.
Use the general from of a parabola

you know the value of c, the y-intercept... y = -4
which means the equation is

now use the other 2 points to get 2 equations in 2 unknowns
(-2, -20) just substitute

this becomes

now the other equation using (4, -20)
The simplified form is
