13 out of the 213 tagged returned
13/213 is estimate of how many fraction returned
proportional, marked/totalmarked≈caught/totalinlake
213/13=total/104
times both sides by 104*13 (cross multiply)
213*104=total times 13
22152=total times 13
divide both sides by 13

Answer:
no
Step-by-step explanation:
Using substitution, subs in the points given
(15) = 5(4) - 2
15 = 20 - 2
Because the 2 sides are NOT equal the line would not pass through the point
Answer:
Commutative
Step-by-step explanation:
You can switch the order.
Answer:
The measure of angle 2 is 52°.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that
and x=6.
From the below figure it is clear that Lines 1,2 and 3 intersect each other at a point and form 6 angles.
It is clear that angle 2 and angle 5 are vertical opposite angles because these angles created by intersection of line 2 and line 3.
If two lines intersect each other then vertical opposite angles are congruent.
(vertical opposite angles)
Substitute x=6.
Therefore, the measure of angle 2 is 52°.
Answer:
A. $12
Step-by-step explanation:
For a quadratic of the form ax²+bx+c, the axis of symmetry is given by ...
x=-b/(2a)
For your quadratic function, the axis of symmetry is ...
s = -(2400)/(2(-100)) = 12
The function has its extreme value on the axis of symmetry. Here, the leading coefficient is negative, so the parabola opens downward. That means the extreme value is a maximum.
Profit will be a maximum at a selling price of $12.
