<h3>The answer as a fraction is 1/2</h3><h3>In decimal form the answer converts to 0.5 which is equivalent to 50%</h3>
===================================================
Explanation:
"given that the first die rolled is a 2" means we know 100% that the first die shows a 2. Either we can see the die or a friend is telling us the status. Since we know the first die is a 2, this means we can effectively ignore it. Everything will hinge on the second die. If the second die shows an odd number, something like 1, then 2+1 = 3 is the result which is also odd.
The general rule is odd+even = odd and even+even = even.
Therefore, the two dice must together be even for the sum to be even.
Of the six possible ways to roll a die {1,2,3,4,5,6}, there are 3 even values {2,4,6} so the chances of rolling an even number on the second die is 3/6 = 1/2. Again we dont need to consider the first die at all since everything practically hinges on this second die.
Answer:
19
Step-by-step explanation:
4 + [(16 - 4) + (12 -9)]
Using PEMDAS, first solve the parentheses.
16-4 is 12 and 12-9 is 3
Rewrite the expression
4+(12+3)
12+3 is 15
4+15
19.
Answer: x=-1
Step-by-step explanation:
Answer: B (I think). Explanation: Turn the mixed fractions into improper fractions. Get a common denominator by multiplying the denominator and the numerator by the same number (common denominator is 8), then add the three improper fractions together. Eden grew 35/8 inches and Eva grew 33/8 inches. When we turn them into mixed fractions we will get, (Eden: 4 3/8) and (Eva: 4 1/8). After that, we subtract them both and get 2/8. We know that 1/4 is 2/8 since if we multiply 1/4 by 2 (by the denominator and numerator), we will get 2/8. (Sorry if you still don’t understand).
