The circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r".
Therefore the radius is √49=7 and the center coordinates are (0,0)
The graphical device that divides data according to the percentage they represent is a pie-chart.
Frequency distribution, relative frequency distribution, or percent frequency distribution all are statistical measures <u>that want to establish the part of the distribution corresponding to each measure</u>, that is, percentages, thus they are represented by pie-charts.
An example, suppose that among 50 people sampled, 20 prefer the NBA and 30 the NFL.
- Thus, 60% of the sample prefers the NFL, and 40% the NBA.
- This information is well represented by the pie-chart sketched at the end of this answer.
A similar problem is given at brainly.com/question/14354536
Let Q represent Quarters
N represent Nickels
We know that Quarters worth 25 cents
Nickels worths 5 cents
If Chris has 2 times as many nickels as quarters means that
N=2Q
Next,
They have a combined value of 210 cents, so
0.25Q+0.05N=210
Substitute N with 2Q
0.25Q+0.05(2Q)=210
0.25Q+0.10Q=210
0.35Q=210
Divided 0.35 to each side
0.35Q/0.35=210/0.35
Q=600 coins
N=2Q
N=2(600)
N=1200 coins. As a result, Chris has 1200 nickels and 600 quarters. Hope it help!
