You can use your calculator to divide it out and find that
or, you can make use of your knowledge of the decimal equivalent if 1/11 (=0.90909...) and multiply that by -8 to get -0.727272... as above.
Answer:
Correct option: A -> 1/24
Step-by-step explanation:
To find the probability of having a card with the value greater than six, the options are: 7 and 8. So there are two options in the total of 8, so the probability is P1 = 2 / 8 = 1/4
The cube has 6 numbers, from 1 to 6, so the probability of rolling a six is P2 = 1/6
To find the final probability, we multiply both probabilities, so:
P = P1 * P2 = (1/4) * (1/6) = 1/24
Correct option: A
Answer: 40
Step-by-step explanation: -5 x -8 is 40 since the negatives cancel each other out, the product is positive :)
Answer:
x=-4/9, y=10/3. (-4/9, 10/3).
Step-by-step explanation:
3x+4y=12
3x=2y-8
--------------
2y-8+4y=12
6y-8=12
6y=12+8
6y=20
y=20/6
simplify,
y=10/3
3x=2(10/3)-8
3x=20/3-8
3x=20/3-24/3
3x=-4/3
x=(-4/3)/3
x=(-4/3)(1/3)=-4/9
x=-4/9, y=10/3. (-4/9, 10/3).
Whenever a number is followed by percent, you can turn it into a fraction by simply moving the decimal places two places to the left:
90.0 % becomes .90
As a fraction, this is 90 over 100. To reduce it to its simplest form, divide by 10:
9/10
