Answer is 14 I think pretty sure hope so yeah
It would be zero because you can’t raise 0 to any positive power.
9) It helps to draw a picture. Since one angle is 60°, the other angle is 120°. When you draw the ddiagonal lines, you will see that you end up with a 30°-60°-90° triangle where √3 is the hypotenuse. The longest diagonal will be across from the 60° angle, which will be length a√3. The length of the hypotenuse is 2a. (Remember: a, a√3, 2a are lengths for this special triangle)
2a = √3 → a = √3/2.
side across from 60° = a√3 = (√3/2)·√3 → side from across 60° = 3/2
Remember that this is only one-half of the diagonal of the rhombus so multiply that by 2.
Length of longest diagonal is 3.
10) Volume of a square pyramid = (1/3) B · h, where B is the area of the base
200 = (1/3)B(12)
50 = B
Since the base is a square, then each side is √50 (which equals 5√2).
Now, to find the lateral edge, use Pythagorean Theorem (a² + b² = c²).
Height (a) = 12, base (b) = 5√2, and lateral edge (c) is unknown.
(12)² + (5√2)² = c²
144 + 50 = c²
194 = c²
√194 = c
Lateral edge is √194.
Answer:
The answer is A. Because 11/9 is greater than 1, the product of 4/5 and 11/9 is greater than 4/5
9/9 is exactly 1. 11/9 is greater than 9/9, so 11/9 is greater than 1. If I added 4/5, the answer is larger than 11/9, therefore the answer is A.
Solution :
Let the distance of the stick from one break be X
And let us assume that 
.
Here, l = length of stick
Therefore, 
We know that, 
, so by definition we get
The cumulative distribution function for R is
When it starts at zero, then r =0. It ends at one when the r has a maximum
value of one.
The probability density function is given by
Now integrating, we find E(R) and 
gives :
Therefore, Var(R)=
