Answer:
-24
Step-by-step explanation:
For this question, all you have to do is multiply the number outside the bracket by the number inside the bracket.
12 x -2
The law of negatives says that when you multiply a positive number by a negative number, the answer will be negative
∴ the answer will be negative
all that's left now is to multiply 12 by 2
12 x 2 = 24 (remember the answer will be negative)
answer: -24

Answer:
The mean and standard deviation of the number preferring the incumbent is mean = 330, standard deviation = 10.59.
Step-by-step explanation:
We are given that From previous polls, it is believed that 66% of likely voters prefer the incumbent.
A new poll of 500 likely voters will be conducted. In the new poll the proportion favoring the incumbent has not changed.
Let p = probability of voters preferring the incumbent = 66%
n = number of voters polled = 500
<u>So, the mean of the number preferring the incumbent is given by;</u>
Mean =
=
= 330 voters
<u>And, standard deviation of the number preferring the incumbent is given by;</u>
Variance =
=
= 112.2
So, Standard deviation =
=
= 10.59
