Answer:
7/20 = x/400
Step-by-step explanation:
Answer:
C. 
Step-by-step explanation:
Given problem is
.
Now we need to evaluate the given limit.
If we plug
, into given problem then we will get 0/0 form which is an indeterminate form so we can apply L Hospitals rule
take derivative of numerator and denominator





=2
Hence choice C is correct.
Slope intercept form:
y = mx + b
Where m = slope and b = y-intercept.
By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.
So now we have:
y = mx + 1/2Next, we'll find the slope.

Plug the coordinates into the formula.

So our slope is 5/8 and the y-intercept is 1/2.
Option A is the answer.
Let
be the weight of i-th player.
1. If the mean weight of 4 backfield members on the football team is 221 lb, then

2. If the mean weight of the 7 other players is 202 lb, then

3. From the previous statements you have that

Add these two equalities and then divide by 11:

Answer: the mean weight of the 11-person team is 
The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.
We know that,
Linear velocity = r x Angular Velocity
where r is the radius.
So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.
So, the correct answer is option C
