Answer:
The expected frequency for each category would be:
10.
Step-by-step explanation:
a) Data and Calculations:
Number of respondents = 30
Number of categories = 3
Political preferences (categories) = 3
Probability of each category or preference occurring = 1/3
Expected frequency for each category = 1/3 * 30 = 10
b) The expected frequency for each political category (political affiliation) can be calculated by multiplying the probability of each category (political preferences) by the number of respondents. Note that the expected frequency will be different from the observed frequency, which is the actual number of times that each category of political affiliations will be preferred.
Answer:
x = 6
Step-by-step explanation:
We want to find x,
to get x alone, we multiple both side by 10
30 divided by 5 is 6
<u>Check</u>:
We can see that 5 x ____ = 10 where ____ is 2
5 x 2 = 10
so 3 x 2 = 6

Answer: -3x² - 2x -57
This is how this would look: 
First I brought the denominator to the top for both expressions.
so I was left with: 2x-6(x+2) - 5x-15(x+3)
I distributed, combined like terms, and simplified.
<em><u> -3x² - 2x -57</u></em> was my answer

Answer:
for (-1,5) the distance is 6. For (-1, -3) its 2
Step-by-step explanation:
(5 - -1) = 6
(-3 - -1) = -2
[-2] opposite is two.
I’m assuming “triple 4” is just 3 times 4.
Using the information from the problem, we can form an equation that reads,
