Answer:
c
Step-by-step explanation:
There are 6 numbers on each die.
The total number of out comes is 6 x 6 = 36.
To get a sum of 4, the combinations are: 1 & 3, 2 & 2 or 3 & 1.
To get a sum of 8, the combinations are: 1 & 7, 2 & 6, 3 & 5, 4 & 4, 7 & 1, 6 & 2, 5 & 3
The total of those combinations are: 3 + 7 = 10 total combinations of a sum of either 4 or 8.
The probability of either is 10/36, which can be reduced to 5/18.
Answer:
11/8 or 1 3/8

So first write down the fraction which is 8/28
then make it into its simplest form which is 2/7
then make it into ration form it is 2:7
reading 2 is to 7
Answer:
First we need to calculate the height of the triangle ( because from that, we can also calculate both x and y)
We know that: h² = b'c'
And in our case:
b' = 9
c' = 3
=> h² = b'c' = 9 · 3
=> h = √(9 · 3) = √27
Now using pythagorean theorem:
(√27)² + 3² = x²
=> x² = 27 + 9
=> x = √(27 + 9) = √36 = 6
So x = 6 and the answer is C.
