Answer:
![P(X\geq 20)= P(X=20)+P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%3D%20P%28X%3D20%29%2BP%28X%3D21%29%2BP%28X%3D22%29%2BP%28X%3D23%29%2BP%28X%3D24%29%2BP%28X%3D25%29)
And replacing using the mass function we got:
And adding the values we got:
![P(X\geq 20) = 0.8381](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%20%3D%200.8381)
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
![P(X\geq 20)= P(X=20)+P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%3D%20P%28X%3D20%29%2BP%28X%3D21%29%2BP%28X%3D22%29%2BP%28X%3D23%29%2BP%28X%3D24%29%2BP%28X%3D25%29)
And replacing using the mass function we got:
And adding the values we got:
![P(X\geq 20) = 0.8381](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%2020%29%20%3D%200.8381)
All you havw to do is put alot of efort
Answer:
6.3%
Step-by-step explanation:
so 5.607 = x% * 89
to find the percent u need to divide : 5.607/89 which is : 0.063
to convert 0.063 to a percent multiply 0.063 by 100 = 6.3%
check :
6.3% *89 = 5.607
Answer:
ASA
Step-by-step explanation:
You can show the angles at either end of segment BC in triangles MBC and LCB are congruent, so you have two angles and the segment between. The appropriate theorem in such a case is ASA.
When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic.
