Answer:
a) We can calculate the mean with the following formula:

And replacing we got:

And for the median first we need to order the dataset on increasing way:
50, 60, 65, 70, 350
Since the sample size is an odd number we can calculate the median as the middle position for the dataset, for this case the 3th position and we got:
Median = 65
b) For this case we can see that we have an outlier present in the data 350, and for this case if we want to give a measure of central tendency is better use the median since this meaure is not affected by outliers. So Lauren should use the median.
Step-by-step explanation:
For this case we have the following data:
350, 70, 65, 50, 60

Answer:
1/2
Step-by-step explanation:
(-9,6), (-3,9)
y2 - y1 = 9 - 6 = 3
x2 - x1 = -3 - -9 = 6
= 3/6 = 1/2
Hi there!
Parabola x² = 12y
→ x² = 4ay
→ 4a = 12
→ a = 12÷4
→ a = 3
So, the co-ordinates of the focus is:-
S(0,a)=(0,3)
→ Let AB be the latus rectum of the given parabola.
→ Coordinates of end-points of latus rectum are (-2a,a), (2a,a)
→ Coordinates of A are (-6,3), while B's coordinates are (6,3).
→ ∆OAB are O(0,0), A(-6,3), B(6,3)
Area of ∆OAB is :-

Answer:
<em>8.25 cc fluid should be drawn into the syringe from the U40 vial.</em>
Step-by-step explanation:
The amount of a U40 vial insulin fluid is 10 cc.
A vial marked U40 has 40 units of insulin per cubic centimeter of fluid.
Suppose, if a patient needs 33 units of insulin, then
cc fluid should be drawn.
So, <u>according to the ratio of "cubic centimeter" to "the units of insulin"</u>, the equation will be.........

So, 8.25 cc fluid should be drawn into the syringe from the U40 vial.
2 1/2 because 50-20 leaves you with 30 so you have one. Than 30-20 leaves you with 10. Now you have two. There isn't another 20 but 10 is half of twenty so that gives you a half so it is 2 1/2
