Answer:
Step-by-step explanation:
the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.
50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.
Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.
this is the formula that can help with any percentage math problem:
The percentage of something ÷ 100% = the number you are looking for ÷ the total
in our case:
40÷100 = x (because it is the unknown term)÷60
from here you cross multiple getting
2400÷100x
which equals
24
now we have to add Vicky's and Iverson's voter
24 + 30= 54
60-54=6
6 students did not participate
Answer:
the value of 2 in 0.812 is 2 thousandths/0.002
0.002 = 2/1000
0.812 = 812/1000
Answer:
c. 0.80
Step-by-step explanation:
Probability from relative frequency:
The probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability that the next bus sold will be yellow or green?
250+150+100 = 500 buses sold
Of those, 250+150 = 400 are yellow or green.
400/500 = 0.8
So the correct answer is:
c. 0.80
This statement is not true, you cannot add denominators if they are not the same
the correct answer is 8/15
brainliest answer please =)
