Answer:
And replacing we got:
And for this case the standard error assuming normality would be given by:
And replacing we got:
Step-by-step explanation:
For this problem we know the following notation:
represent the sample size selected
represent the number of airplane travelers who after a flight would fly that airline again
The estimated proportion for this case would be:
And replacing we got:
And for this case the standard error assuming normality would be given by:
And replacing we got:
You start by finding the total sq ft you need to cover so one board is 8x3 so that's 24 then multiply that by the number of boards which is 12 so you get 288 sq ft you need to cover. Then you divide by 125 which is how much one can could cover and you get 2.3 cans but you can't buy a third of a can do you round up to three. The three cans times the price of 3.50 gives you $10.50 as your final answer
The price of movie after a year would be
7.50+
= 7.7625$
(1) x = 2y
(2) x + 4 = 3y + 1
subtitute (1) to (2)
2y + 4 = 3y + 1 |subtract 4 from both sides
2y = 3y - 3 |subtract 3y from both sides
-y = -3 |change the signs
y = 3
subtitute the value of y to (1)
x = 2 · 3
x = 6
Answer: x = 6 and y = 3.
