Expected value = -1(1/6) + 2(1/6) + 3(1/6) - 4(1/6) + 5(1/6) - 6(1/6) = -1/6 + 2/6 + 3/6 - 4/6 + 5/6 - 6/6 = -1/6 = -0.167
Answer:
3/22
Step-by-step explanation:
-1/4 . (-6/11)
- You have to multiply the signs: As both are negative, the result will be positive.
- You have to multiply the numbers in the top part (numerators) and the numbers in the bottom part (denominators)
1 . 6 / 4 . 11 = 6/44
- Finally, you must simplify the answer by dividing both numbers among the same divisor, in this case the number is 2
6÷2 / 44÷2 = 3/22
Answer:
-(276÷0.12)=-2300
Step-by-step explanation:
Answer:
We have that y = 21 when x = 11.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.
33 - 7
y - 11
So
11y = 33 -7
y - 11
Dividing both sides by 11
Y = 3 * 7 = 21
We have that y = 21 when x = 11.
Answer:
