The answer is 60 degrees
Steps: first add the two angles you know 50+70=120
Then subtract it from 180 because a triangle has a total of 180 degrees 180-120=60
-3*2*2 = - 12
Multiply all to get the answer
Answer:
−65/−12 reduces to 65/12. Double check to ensure that you've copied down the first two possible answers correctly.
Step-by-step explanation:
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>.
this equation is in point slope form
y-y1 =m(x-x1)
where m is the slope
m=8
