Yeah, they're equal.
8 * 3 = 24 and 8 * 4 = 32
so 24x+32 = 24x+32
Vowels include AEIOU, so in the first box there is 2 vowel out of the 5 letters so 2/5 probability for the first box. Box 2 includes 2,4,6,8 as the even numbers out of the 9 numbers so 4/9
If you were solving the probability for each box individually that would be your answer
However if you are doing statistics and need to do it in a certain order you multiply the fractions
2/5 x 4/9 = 8/45
(.17777)
This leaves you with a 17% (8/45) chance of picking a vowel then an even number.
Answer: First option 108°
Each label is equivalent to an angle of:
Angle=360°/n
Number of label: n=10
Angle=360°/10
Angle=36°
To map label i to label f in a counterclockwise rotation, we must pass by 3 regions: i to h, h to g, and g to f; each one of 36°. Then the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f is:
Measure=3(36°)
Measure=108°
E.g. 1/4 and 1/3
The LCM of the denominators (4 and 3) is 12
So 1/4 can be written as 3/12
And 1/3 can be written as 4/12
You can then add the fractions if you wish to make 7/12
It is divided by 2 each time, and so your next number will be 4, since 8/2 = 4
C) 4
hope this helps :D
