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

Answer:
In Point Slope Form: y+6=4(x-1)
Step-by-step explanation:
<u>First you have to find the points given which are:</u>
<u>Label the points x1, y1, x2, and y2</u>
- It already gives you the slope which is 4.
<u>Plot the points in the equation of Point Slope Form:</u>
<em><u>y1-y2=m(x-x1)</u></em>
<u>Simplify: y1-6=4x-4</u>
<u>It doesn't ask you to simplify but why not! </u>
The answer to = 2x27 is f(x)
Answer:
The anwser is B.) 49
Step-by-step explanation:
If you subtract 79 (the amount of 7th graders riding the bus) from 128 (the total number of 7th graders) you will get 49. Therefore 49 is the answer.
Hope this helps!!
