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:
-7 i hope this right
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 44
2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
4(\frac{4r}{4}-\frac{28}{4})4(
4
4r
−
4
28
)
3 Simplify each term in parentheses.
4(r-7)4(r−7)
Answer:
$0.19.
Step-by-step explanation:
Unit rate / ounce = 2.66 / 14
= $0.19.
5-7 = -2 and 1-6= -5 so the slope would be 2/5. you would set it up like this:
y=2/5x and then your y-intercept
You can factor it out :)
4x+12=4(x+3)
