Answer:
Step-by-step explanation:
1.2307692307692.
The first step is to find the proportionality constant.
The formula is
z = kx/y
1.2307692307692 = k * 4/13 Multiply both sides by 13
1.2307692307692 * 13 = 4k
16 = 4*k Divide by 4
k = 16/4
k = 4
=================================
z = k*x/y
x = 9
y = 20
k = 4
z = 4 *9/20
z = 36/20
z = 1.8
Answer:
133
Step-by-step explanation:

Answer:
127
Step-by-step explanation:
m<PQR and m<RQS are supplementary angles so their sum is 180
3x - 5 + x + 1 = 180 add like terms
4x - 4 = 180 subtract 4 from both sides
4x = 176 divide both sides by 4
x = 44
m<PQR is 3x - 5 replace x with 44
3*44 - 5 = 127
Answer:
We would expect about 95 of the 100 confidence intervals to contain the proportion of all citizens of the United States who are optimistic about the economy.
Step-by-step explanation:
The purpose of sampling is to make statistical inference the entire population of interest. Thus, we generalized to the entire population the findings from the sample.
For instance, we don't need to drink entire cup of coffee to know whether the sugar is enough or not. We only need to stir (randomly) and take a sip from the cup of coffee. We usually assume that, if the content we sipped is satisfactory to our taste, the entire content of coffee inside the cup is satisfactory. Using this illustration, we would expect that the findings of the survey should be generalized to the entire population of study.
Thus, <em>we would expect about 95 of the 100 confidence intervals to contain the proportion of all citizens of the United States who are optimistic about the economy</em>.
