That answer I C. I hope this helps!!!!
Let us compute first the probability of ending up an odd number when rolling a dice. A dice has faces with numbers 1 up to 6. The odd numbers within that is 3 (1, 3 and 5). Therefore, each dice has a probability of 3/6 or 1/2. Then, you use the repeated trials formula:
Probability = n!/r!(n-r)! * p^r * q^(n-r), where n is the number of tries (n=6), r is the number tries where you get an even number (r=0), p is the probability of having an even face and q is the probability of having an odd face.
Probability = 6!/0!(6!) * (1/2)^0 * (1/2)^6
Probability = 1/64
Therefore, the probability is 1/64 or 1.56%.
Just put 4 as x in the equation and solve it. The new equation is:
sqrt(2*4)+1+3 = 0
Now we can solve it.
sqrt(2*4) becomes sqrt8:
sqrt8+1+3=0. -------> sqrt8+4=0
The sqrt of 8 is about 2.83.. so 2.83+4 is:
6.83
So we have 6.83 as the answer
but 6.83 does not equal 0 so x cannot equal 4
Y + 4/9 = 2/3
Let's convert 2/3 into 6/9 so it will be easier to subtract.
Y + 4/9 = 6/9
Subtract 4/9 on both sides.
Y = 2/9 Hope this helps!
