Step-by-step explanation:
One's digit of N can be 2 or 7.
How do you want me to figure out this problem if I don’t have enough information
I don't know. I'll have to figure it out.
Probability =
(number of successful possible results) / (total possible results) .
Total possible results for the spinner . . . 8
Successful ones (getting a 1, 2, 3, 4, or 5) . . . 5
Theoretical probability = 5/8 .
So you expect (5/8 of 150) spins to be successful.
(5/8 times 150) = 93.75
Yes !
93 or 94 is a good answer.
Remark
To find any common denominator, write down all the prime factors and pick out what you need to make an LCD.
Method
x has one x
2x^2 = 2 * x * x
Your LCM is
one 2
two xs.
LCM = 2*x*x
LCM = 2x^2
The length of the radius would be 18cm long
