Answer:
D
Step-by-step explanation:
The margin of error represents the amount of percentage points that the real value can differ from the value given in the sample. The margin of error is ±3%, meaning that 50.6 (the sample value) ± 3% is the margin of error, resulting in a range of (47.6, 53.6) as our margin of error. Anything in that range can be the true proportion of voters that would vote for the ballot measure. As the range contains value both less than and greater than the 50% needed to pass, it is impossible to say, given the data, that the voters will vote yes or no to the ballot.
12 and 1/8, I just simplified 2/16 to 1/8
Answer:
x^2 +3x+2
Step-by-step explanation:
the question has been a bit expanded so this is what you should do next
x(x+1) +2(x+1) i used the figures in the first bracket to multiply the second bracket
then use the figures outside the bracket to multiply what is inside i.e
x×x =x^2 and so on that gave me
x^2 +x+2x+2 =x^2 +3x because there's like an invisible 1 +2
