9 batches because if you kept counting until you got close to 12 cups of flour you would get 9 batches
-21 this is because you can solve for g, to solve for you you subtract 4 from both sides and -17-4= -21
From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
Answer:
Step-by-step explanation:
When you put this into your calculator, you get
42.5793
A: The largest number is too small
B: The largest number is too small
C: This is the answer. The calculator answer will round to 42.58, but before you round the answer is between 42.57 and 42.58
D: and again the largest value is not big enough
Answer:
2) 0.0914
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
A survey of 114 drivers is performed and 62 people say they will not drive until all passengers in the vehicle are buckled up.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
What would be the margin error for this confidence interval?
Thus the margin of error is 0.0914, option 2).
