What is the probability of the complement of spinning an even number by using the spinner below

Answer:
Step-by-step explanation:
We first need probability of spinning an even number BUT its complement.
THe complement is basically all outcomes THAT ARE NOT THE EVENT.
So, we find the probability of even number then we subtract that probability from 1. Because:
P(event) + P(complement of event) = 1
Now,
Looking at the spinner, it has total 8 divisions.
The number of even numbers is 3 (2, 4, and 2)
So
P(even) = 3/8
But we need its complement, so we have:
P(even) + P(complement of even) = 1
3/8 + P(complement of even) = 1
P(complement of even) = 1 - 3/8 = 5/8
The answer is

Answer:
The length of the field on the drawing is <u>55 cm</u> that is option <u>D</u>.
Step-by-step explanation:
Given:
Mark made a scale drawing of a soccer field, using a scale of .5 cm=1 m.
The actual length of the field is 110 m.
Now, to find the length of the field on the drawing.
Let the length of the field on drawing be
As given,
Drawing of a soccer field, using a scale of 0.5 cm=1 m.
So, 0.5 cm is equivalent to 1 m.
Thus, is equivalent to 110 m.
Now, to get the length of the field on the drawing by using cross multiplication:
By cross multiplying we get:
Therefore, the length of the field on the drawing is 55 cm that is option D.
