The measure of central angle XYZ is 1.25 radians.
What is the area of the shaded sector?
Answers
Note that a sector is the area bounded by two radii and the included arc. When trying to calculate for the area of the sector, you’ll use the formula A=n/360 (pi)(radius)^2. Remember that the n in the formula refers to the measure of the central angle in degrees. Since the given data in the problem is in radians term, you can convert it by multiplying 1.25 to 180/pi. Then you can now input the converted value to the formula of finding the area of the sector.

Answer:
Neither SSS nor SAS apply.
Step-by-step explanation:
SSS (Side-Side-Side)-
If three pairs of sides of two triangles are equal in length, then the triangles are congruent.
SAS (Side-Angle-Side)-
If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent.
It given in the picture that,
- AC = AD (Side)
- BC = DE (Side)
- m∠BAC = m∠EAD (Angle)
So, ΔABC and ΔAED will not be congruent by either SSS or SAS.

The table gives the probability distribution of the annual rate of return on the stock of MNP Company, Inc.
The expected value of the rate of return is ______%.
Answers
Answer: The expected value of the rate of return is 23.5%.
Step-by-step explanation:
Since we have given that
Annual Return Probability
15% 0.2
20% 0.4
30% 0.3
35% 0.1
We need to find the expected value of the rate of return:
As we know the formula for "Expected value ":
So, it becomes,
Hence, the expected value of the rate of return is 23.5%.
15%*0.2 + 20%*0.4 + 30%*0.3 + 35%*0.1 = 23.5%
Answer:
The expected value of the rate of return is 23.5%

f(t) = -16 t^2 + 25t + 6
f(t) = height.
hieght = 0 = -16t^2 + 25t + 6
Find t using the quadratic formula,
t = ( - 25 +/- √[25^2 - 4 (-16)(6)] ) / [2*(-16)]
t = [-25 +/- √ (625 + 384) ] / -32
t = [-25 +/- 31.76] / -32.
You will obtain two results one positive and one negative. Take the positive only as the other one has no physical meaning. t = 1.77 s.
