Answer:
170 muffins
Step-by-step explanation:
We start from the ratio between baker B and C
The ratio of cakes baked by both is 4:3.
We know baker C baker 150 muffins:
This mathematically means:
B:C = 4:3 = B:150
This means 4/3 = B/150
B = (4 * 150)/3 = 200
Baker B baked 200 cakes
We now move back to the first statement
The ratio between baker A and B is 8:5
Mathematically, this means:
A:B = 8:5 = A:200
8/5 = A/200
A = (8 * 200)/5 = 320
The number of cakes baker A baker pass baker C would be 320 - 150 = 170 muffins

Answer: The interval is 0.9 ± 0.0259 and margin of error is 0.0259
Step-by-step explanation: <em>Confidence interval for a proportion in one sample</em> is the estimate of the proportion of a population. It is calculated following the next steps:
1) Find the proportion
, in which x is the number of people with the desired condition. In our case, p=0.9;
2) Calculate margin of error, i.e.:

z is z-score, which for a 95% confidence, equals 1.96;
Substituting with the data given:
= 0.0259
3) Write: p ± 
In our case, the interval will be 0.9 ± 0.0259.
<u><em>Margin</em></u><em> </em><u><em>of</em></u><em> </em><u><em>error</em></u> is the random sampling error in the results of a survey, i.e.,it shows you how far your result will be from the real value. For the Harris poll, margin of error is 0.0259
Answer:
16
Step-by-step explanation:
The equation is 3/4x=12, so you would just divide 12 by 3/4 to get 16 as x
B because it’s in the middle
