Answer:
the probability of picking an odd number is 7/10
The probability of getting an odd number is 7/10.
Step-by-step explanation:
There are 7 odd numbers: {1, 3, 7, 9, 15, 19, 21}
There are 3 even numbers: {2, 10, 20}
There are 10 numbers overall: {1, 2, 3, 7, 9, 10, 15, 19, 20, 21}
7 odd numbers out of 10 numbers is equal to 7/10
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m
c
I think its c because there is no relation between 2x-1 and 4-x ,it is not equals its + because there is no equals in a straight angle
16x^2 - 4
4(4x²-1)
4((2x)²-1²)
4(2x+1)(2x-1)
