Answer:
P = 4z +5
Step-by-step explanation:
The side lengths are given as (z), (z+5), (2z). The perimeter is the sum of the side lengths:
P = z +(z +5) +2z
P = 4z +5
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: There are 12 almonds and 16 cranberries.
Step-by-step explanation: This is a proportions problem.
- If the ratio of almonds to cranberry is 3 to 4, that means for every 7 pieces, there are 3 almonds and 4 cranberries.
- If there are a total of 28 pieces, you need to multiply each piece of the original proportion by 4 (28/7 = 4).
- 3 * 4 = <em>12 almonds</em>
- 4 * 4 = <em>16 cranberries</em>
- Check: 12 + 16 = 28
