Answer:
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...
Step-by-step explanation:
Unable to use a single equation to define this sequence
The rule is x₁ = 2 x₂ = x₁ * 2 x₃ = x₂ + 3 x₄ = x₃ * 2 x₅ = x₄ + 3 ...

Answer: 1/70
Step-by-step explanation:
This is a question that can also be interpreted as what is the probability of having the first number of a phone number to be 8 and the last number of the phone number to also be 8. This answer gives the fraction of the phone numbers that starts with 8 and end with 8.
Since three numbers (0,1,2) cannot start a phone number and we are left to pick from 7 numbers,
then the probability of figure "8" starting phone number = 1/7
Since all 10 numbers can possibly end a phone number,
then the probability of having figure "8" as the last digit of a phone number = 1/10
Hence probability of having "8" as the first and last digit of a phone number = fraction of total telephone numbers that begin with digit 8 and end with digit 8 = 1/7 × 1/10 = 1/70.
Answer:
cool thats nice
Step-by-step explanation:
Answer:
they are equal because while solving 2b+5+1b it will come 3b+5 so they are equal
Answer:
Step-by-step explanation:
The average length of the weird trapezoidal shape on the left is
(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.
The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.
Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.
