Answer:
Step-by-step explanation:
In probability, "OR" means "+" and "AND" means "*".
The total amount of people is:
32 + 54 + 78 + 112 + 96 = 372
Number of diabetic patients are 54
Number of eye patients are 112
Since we want "OR", we will add the two probabilities:
P(diabetic or eye problem) = 54/372 + 112/372 = 83/186
I believe the greatest common factor would be 1 because there are no other multiples that are the same. 1•21=21, and1•40=40
Answer:
Like on a test if you get extra credit.
Step-by-step explanation:
Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
Answer:
<u>Based on the results the boutique could be located there.</u>
<u>Step-by-step explanation:</u>
Note: The average income (the mean) is calculated by summing the total incomes then divided by the total sample–9.
The mean ù (average income) = $28,000 + $24,000 + $26,000 + $25,000 + $23,000 + $27,000 + $26,000 + $22,000 + $24,000= $225,000/9= $25,000 (which is ≥ $25,000.
Based on the results of the p-value, using the 5% significant level <em>we fail to reject the null hypothesis</em> (ú≥25,000).
