Answer:
Its a right isosceles triangle
Answer: 4
Step-by-step explanation:
Given the following :
P = probability of success = 0.5
n = number of trials = 8
The expected value of a binomial distribution with probability of success P and number of trials n is defined by:
E(n, p) = n * p
Therefore, expected value when P = 0.5 and n = 8
E(8, 0.5) = 8 × 0.5
= 4
The expected value of the binomial distribution is 4
The answer is 45.2 by my calculations!!! I hope that helps
Answer:
1/(5x^8y^13)
Step-by-step explanation:
To simplify this exponential expression we must use some of the laws of exponents, specifically the quotient law. The quotient law states that if the base is the same and you're dividing we subtract the exponents and so: ![\frac{a^m}{a^n}= a^{m-n}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5Em%7D%7Ba%5En%7D%3D%20a%5E%7Bm-n%7D)
Therefore:
![\frac{3x^{-6}y^{-3}}{15x^2y^{10}} =\frac{x^{-6-2}y^{-3-10}}{5}=\frac{x^{-8}y^{-13}}{5}\\ \\\frac{1}{5x^8y^{13}}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E%7B-6%7Dy%5E%7B-3%7D%7D%7B15x%5E2y%5E%7B10%7D%7D%20%3D%5Cfrac%7Bx%5E%7B-6-2%7Dy%5E%7B-3-10%7D%7D%7B5%7D%3D%5Cfrac%7Bx%5E%7B-8%7Dy%5E%7B-13%7D%7D%7B5%7D%5C%5C%20%20%5C%5C%5Cfrac%7B1%7D%7B5x%5E8y%5E%7B13%7D%7D)
Step-by-step explanation:
it's an isosceles triangle
ht will intersect the base at 90°
so x^2 =33^2+15^2
x = 36.2
