Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
Answer: Yes its B sorry if im wrong
Step-by-step explanation:
have a nice day
Answer:
y = 3/5x - 2
y = -1.5x + 3.5
y = 6x - 6
Step-by-step explanation:
<u>For equation 3x - 5y = 10:</u>
Rearraging gives;
5y = 3x - 10
Dividing throughout by 5 gives;
y = 3/5x - 2
<u>For equation 3x + 2y = 7:</u>
Rearraging gives;
2y = -3x + 7
Dividing throughout by 2 gives;
y = -3/2x + 3.5
<u>For equation 3x - 1/2y = 3:</u>
Rearraging gives;
1/2y = 3x - 3
Multiplying throughout by 2 gives;
y = 6x - 6
Answer:
4 seconds
Step-by-step explanation:
When the ball hits the ground the height is 0
-16t² + 64t = 0
Divide both sides by -16
t² - 4t = 0
Factor out t
t(t - 4) = 0
From the zero product rule
t = 0 and t - 4 = 0
t = {0, 4}
The ball hits the gound after 4 seconds
Answer:
x=32
Step-by-step explanation:
