Answer:
5/12
Step-by-step explanation:
15 students went to hear the doctor speak and 21 students went to other sessions
How many students are there? 15 + 21 = 36 students
Therefore, the probability to randomly select a student that went to hear the doctor is 
, then simplifying it by 3 is 
.
If we want to express it in percentage it would be 41.6%
EF is tangent to the circle we'll assume; otherwise there's no progress.
Call the center C. ECD is isosceles, formed from two radii and the chord.
Angle CED is complementary to DEF
CED = 90 - 65 = 25 degrees
CDE is congruent, isosceles triangle and all that: CDE=25
That leaves DCE=180-25-25=130 degrees
That's the measure of arc DE as well:
Answer: 130 degrees, choice A
We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
This is, indeed correct, thus, this
<em>is </em><em>
a right triangle.</em>
The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total cost of rental for each truck in x hours.
From the table, for company A:
For company B:
The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.

The amplitude of this function is 4/5. Be sure you understand why that is so.
