A common element or description on a pie chart is a percentage. The reason is that percentages are given as a part out of a total (100%). Pie charts are used to see how individual parts compare to the whole, so percents are often times used to show this.
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
<em><u>The GCF ( Greatest Common Factor ) of 12, 28, and 4 is 4</u></em>
Answer:
Option B
Step-by-step explanation:
Given that two variables in table as
Total Average
x 2 6 7 8 12 35 7
y 15 13 9 8 5 50 10
xy 30 78 63 64 60 295 59
(x-7)^2 25 1 0 1 25 52 10.4
(y-10)^2 25 9 1 4 25 64 12.8
Var x = 10.4 and std dev x = 3.225
Var Y = 12.8 and std dev Y = 3.578
Cov (xy) = E(xy)-E(x) E(Y)=59-70=-11
Correlation coefficient r
= Cov /sx sy = -11/(3.225)(3.578)=-0.9532
Round off to get
r=-0.953
Henceoption B is right.
The correct answer is C !
