Answer:
1 a = 70%
b 6.5 times
c green = 16%
2. ????? Very poorly worded question
2. a 54%
b. 46%
c. 70%
d. 27%
Step-by-step explanation:
1. Students in a class were asked to tell their favorite color.
a. What percent said red, blue, or yellow? __% said red, blue, or yellow.
red is .26
blue is .40
yellow is .04
---------------------
.70 = 70 %
b. How many times more students said red than yellow?
red .26
yellow is .04
.26/.04 = 6.5 times
c. What percent of students said green? __% said green.
The circle must total 100 %
Red + blue + yellow + purple + green = 100
26+ 40 + 4 + 14 + green = 100
84 + green = 100
Subtract 84 from each side
84-84 + green = 100-84
green = 16
2. Which two methods could be used to find the percent of students who said green?
We can either convert the percents to decimals or the decimals to percents
The total percents must equal 100%
The total decimal must equal 1
a. Find the sum of the percents given in the circle graph.
If they only want the ones written on the graph as percents
(14+40) = 54%
b. Find the sum of the percent forms of the numbers given in the circle graph. Subtract the result from 100%.
100 - 54% = 46%
c. Find the sum of the decimal forms of the numbers given in the circle graph. Subtract that sum from 1. Change the result to a percent.
.26+.04 = .3
1-.3 = .7
70%
d. Find the sum of half of the percents given in the circle graph. Subtract that total from 50%.
1/2 (46%) = 23%
50 -23 = 27%
, we have for 
the Taylor series expansion about 0 as
with 
, so that the series is equivalent to
, we have
