Answer:
MP= (1,-3.5) or written another way MP= (1,)
Step-by-step explanation:
Midpoint formula:
-5+7=2 -2+-5=7
2/2=1 -7/2=-3.5
Answer:
The margin of error is of 0.1282 = 12.82%.
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 conducted by General Motors of 38 drivers in America, 34 indicated that they would prefer a car with a sunroof over one without.
This means that
99% confidence level
So , z is the value of Z that has a p-value of , so .
What is the margin of error?
The margin of error is of 0.1282 = 12.82%.
If he pays with a £5 note and gets 30p change, that means the total cost was £4.70
All the items prices have to add up to £4.70
£1.18 + 94p = £2.12 so the two jars of jam together must cost £2.58 (£4.70 - £2.12).
If two jars cost £2.58 then one jar must cost half of that: £1.29
One jar = £1.29
Answer:
The hat cost £5 while the a shirt cost £6
Step-by-step explanation:
What I did was Guess and check until I finally found each of there amount.
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:
The given line is:
So we have:
We find
So, a line perpendicular to the one given is of the form:
We substitute the given point to find "b":
Finally we have:
In point-slope form we have:
