Answer:
Step-by-step explanation:
A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.
In your case, for every 40 boys, there are 20 girls. if we simplify this all the way down, we can get 2 to 1.
All of the following are ratios that apply to your question:
40 to 20
20 to 10
10 to 5
4 to 2
2 to 1

Answer:
What is the question
Step-by-step explanation:
FINISH
The first graph since it’s increasing rapidly while the second one is a parabola.
A. Is an exponential function
Using it's concept, it is found that the probabilities are given as follows:
a.1/2, 1/9, 5/9.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 90 out of 180 individuals are children, hence the probability is given by:
p = 90/180 = 1/2.
Out of 90 adults, 60 - 50 = 10 preferred cheeseburgers, hence the probability is given by:
p = 10/90 = 1/9.
Of the 180 individuals, 90 are children, and 10 are adults who prefer cheeseburgers, hence the probability is given by:
p = 100/180 = 10/18 = 5/9.
Hence option a is correct.

<span>Since these are done in order, and without replacement:
Lila selecting black = 7/12 (7 black ribbons out of 12 ribbons total)
Jessica *then* selecting a green ribbon = 5/11 ( 5 green ribbons left out of 11 ribbons left)
Chance of this specific event = (7/12)*(5/11) = 35/132</span>Mike <span>· 6 years ago</span>
