Answer: Sorry if too late, but
24 letters in the alphabet excluding I and O= 22
22+9=31
(a)- 31x31x31x31x31x31=887,503,681
(b)- multiply 31 seven times (275,126,141 I think)
(c)- 31^7 divided by 31^6 = 31

Answer: 0.75
Step-by-step explanation:
Given : Interval for uniform distribution : [0 minute, 5 minutes]
The probability density function will be :-
![f(x)=\dfrac{1}{5-0}=\dfrac{1}{5}=0.2\ \ ,\ 0](https://tex.z-dn.net/?f=f%28x%29%3D%5Cdfrac%7B1%7D%7B5-0%7D%3D%5Cdfrac%7B1%7D%7B5%7D%3D0.2%5C%20%5C%20%2C%5C%200%3Cx%3C5)
The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-
![P(x>1.25)=\int^{5}_{1.25}f(x)\ dx\\\\=(0.2)[x]^{5}_{1.25}\\\\=(0.2)(5-1.25)=0.75](https://tex.z-dn.net/?f=P%28x%3E1.25%29%3D%5Cint%5E%7B5%7D_%7B1.25%7Df%28x%29%5C%20dx%5C%5C%5C%5C%3D%280.2%29%5Bx%5D%5E%7B5%7D_%7B1.25%7D%5C%5C%5C%5C%3D%280.2%29%285-1.25%29%3D0.75)
Hence, the probability that a randomly selected passenger has a waiting time greater than 1.25 minutes = 0.75
You need to add al the number together
Answer: OPTION A
Step-by-step explanation:
You can convert 30 kilograms to grams (
), then:
![(30\ kilograms)(\frac{1,000\ grams}{1\ kilogram})=30,000\ grams](https://tex.z-dn.net/?f=%2830%5C%20kilograms%29%28%5Cfrac%7B1%2C000%5C%20grams%7D%7B1%5C%20kilogram%7D%29%3D30%2C000%5C%20grams)
Then, if a book in the bookcase has a mass of 400 grams and you need to find the number of books of the same mass that would take to equal the mass of the bookcase, you can divide the weight of the bookcase (in grams) by the weigth of one of these books.
Therefore:
![books=\frac{30,000\ grams}{400\ grams}\\\\books=75](https://tex.z-dn.net/?f=books%3D%5Cfrac%7B30%2C000%5C%20grams%7D%7B400%5C%20grams%7D%5C%5C%5C%5Cbooks%3D75)
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem, a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.
