Multiplying 5 to the first fraction we get 15/25+1/25=16/25
Answer:
Step-by-step explanation:
You need to factor out the greatest perfect square factor possible.
The expected value of the number of points for each turn is 0.25
<h3>What is expected value?</h3>
Expected value describes the long term average level of a random variable based on its probabilty distribution.
Now, Probability that 2 heads come up is
P(2 is H) = 1/4
Probability that 1 heads come up is
P(1 is H) = 2/4
⇒P(1 is H) = 1/2
Probability that no head will come up
P(no H's) = 1/4
Hence, the expected value for winning of 2points, 1point and lose of3 points is given as-
Expected value = 2 * P(2 is H) + 1 * P(1 is H) - 3 * P(no H's)
⇒Expected value = 2 * 1/4 + 1 * 1/2 - 3 * 1/4
= 0.5 + 0.5 - 0.75
⇒Expected value = 0.25

1.)convert into equation: 90=11x
2.)simplify and solve: x=8.18 lbs

Answer:
6.347 g Zinc to the nearest thousandth.
Step-by-step explanation:
Using the molar atomic mass of the elements:
65.38 g Zinc produces 65.38 + 2(16 + 1.008) = 99.396 g Zn(OH)2
So by proportion amount of zinc required to produce 9,65 g Zn(OH)2
= (65.38/99.396) * 9.65 g Zinc
= 0.65777 * 9.65
= 6.347g Zinc.
