If we consider only the people who named a rainbow color (red, orange, yellow, green, blue, or purple), what percentage of those people preferred red?
Answers
Answer:
20%
Step-by-step explanation:
Method 1
Percentage of people who preferred red:
= 13%
Percentage of people who named a rainbow color:
= 13 % + 4% + 5% + 15% + 16% + 12%
= 65%
Percentage of people who preferred red from those who named a rainbow color:
= (13% ÷ 65%) × 100
= 20%
Method 2
Number of people who preferred red:
= 13% of 500
= 13% × 500
= 0.13 × 500
= 65
Percentage of people who named a rainbow color:
= 13 % + 4% + 5% + 15% + 16% + 12%
= 65%
Number of people who named a rainbow color:
= 65% of 500
= 65% × 500
= 0.65 × 500
= 325
Percentage of people who preferred red from those who named a rainbow color:
= (number who preferred red ÷ number named rainbow color) × 100
= (65 ÷ 325) × 100
= 20%
Pls Brainliest!
Answer:
20%
Step-by-step explanation:
The rainbow colors add up to 13 + 4 + 5 + 15 + 16 + 12 = 65 percent of the pie chart. So, 65% ∙ 500 = 325 people in the survey named a rainbow color. Of these, 13% ∙ 500 = 65 named red.
Therefore, if we consider only the 325 people who named a rainbow color, the percentage of those people who preferred red is
65/325 = 1/5 = 20%
(You may notice that the answer would still be 20% even if the total number of people in the survey were some number other than 500. This is because 13% is 20% of 65%, no matter what these are percentages of!)
The student council at DMS is selling t-shirts for spirit week. The company they have chosen to make the shirts charges a one-time design fee of $50. The t-shirts will cost $5.25 per shirt. If the school collects $1362.50 for the shirts were sold?
Answers
I suppose it asks for how many have been sold.
So we have $50 for design fees.. then $5.25/shirt..
The total is $55.25 per shirt.
We divide $1362.50 to $55.25 and we get 24 shirts with $36 set loose.

The bar graph shows the results of spinning a spinner 100 times. Use the bar graph to find the experimental probability of not spinning a 5.
PLEASE QUICK
Answers
Answer:
81%
Step-by-step explanation:
1.
We know that the probability of spinning a five is 19% since:
19/100 = 0.19 = 19%
However, we are looking for the probability of NOT spinning a five. So, we will have to find the probability sum of the remaining numbers (1, 2, 3 and 4).
2.
- The probability of spinning a one is 20% since:
20/100 = 0.2 = 20%
- The probability of spinning a two is 18% since:
18/100 = 0.18 = 18%
- The probability of spinning a three is 22% since:
22/100 = 0.22 = 22%
- The probability of spinning a four is 21% since:
21/100 = 0.21 = 21%
3.
Now we will add all of these probabilities together to find the total probability of NOT spinning a five!
20% + 18% + 22% + 21% = 81%
Therefore, the probability of not spinning a five is 81%.
(While writing all of this down, I realized it was completely unnecessary)
Basically, the total probability of all of these numbers is equal to 100%. The probability of spinning a five is 19% as we inquired above. Therefore, all we need to do is subtract 19% from 100%!
100% - 19% = 81%

Answer:
the answer for this question should be 6 because remember we need to substitue n by -3 so first we need to solve the exponent one so we replace it.
-3^2= 9
-3 times -3= 9 and remember this rule when we multiply an negative times a negative is positive so it would be 9 for n^2 so we need to add 9+-3 and we get an answer of 6 so 6 is the correct answer and remember if the base is an negative and the exponent is even the answer is positive but if it is odd it would be negative.
hopefully 6 is the correct and have a great day.

Answers
The number of the blue leashes will be 240.
What are linear equations?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
It is given that:-
A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.The number of the blue leashes will be calculated as:-
L = 320
B + P + g = 320
{ (320 x 0.3 ) } + 0.7 ( B + g ) = 320
( 96 ) + ( 2.8g ) = 320
2.8g = 320 / 96
g = 222 / 2.8 = 80
Now B = 3 x g
B = 3 x 80
B = 240
Therefore the number of the blue leashes will be 240.
