Answer:
1.1, 12, 99
Step-by-step explanation:
For the first one, we divide 2.5 by 2.2 (2.5/2.2) to get approximately 1.1 kilograms. So it would be the first option. For the second one, we know that 8x6=48, so we multiply 2 by 6 to get 12/48, so it would be the second option. For the third one, we can do this problem: 110/20 to get 5.5. We can multiply 18 by 5.5 to get 99. So that means the answer would be the first option.
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

Answer:
57/100
Step-by-step explanation:
This is the answer because:
1) Since 0.57 in the hundredths place, the denominator is going to be 100
2) We have 57 of a 100, therefore, 57 is going to be the numerator
3) Now, our fraction is 57/100
4) We cannot simplify this fraction any further because they do not have any common multiples or factors
Hope this helps!
Assume the radius is R.
2*pi*R = 28 -> R = 14/pi
So the area will be pi*R^2 = 196/pi
