REVISED ANSWER.
In the picture, I have drawn on the example given. the RC and PD are the same because They are across from each other perfectly. So the answer is still PD=400m but if there can be two answers then I would have to say another possiblity would be 200m for the diameter of the pond. The wording of this problem is tricky and the picture can throw you off a bit but I did my best to answer properly here.
So if you could mark brainliest that would be awesome.
Answer:
24m
Step-by-step explanation:
Answer:
{2, 3, √13}
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides equals the square of the third side (Pythagoras).
Let's check each set of sides in turn.
A. {2, 3, √13}
2² + 3² = 4 + 9 = 13
(√13)² = 13
This is a right triangle.
B. {5, 5, 2, √10}
This is a quadrilateral (four sides).
C. {5, 12, 15}
5² + 12² = 25 +144 = 169
15² = 225
This is not a right triangle.
Option A is correct
assuming we use the Pythagorean theorem whose formula is c²= √a² + b²
C being the longest side, a=15 and b=20
c² = √15²+ 20²
c² = √625
c= 25
if you try this formula with the other options it shows it's not a right triangle
Using a discrete distribution, we have that:
a) The expected value is of $250 per policy sold.
b) The expected profit for 10,000 policies is of $2,500,000.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Considering that an insurance profit sells for $600, the distribution of the company's earnings is given as follows:
Hence the expected value for a policy sold is given by:
E(X) = 600(0.965) - 4400(0.02) -9400(0.01) - 29400(0.005) = 250.
For 10,000 policies, the expected profit is given by:
E = 10000 x 250 = 2,500,000.
