Answer:
-.91
Step-by-step explanation:
I'm not 100% sure, because i don't have graphing calculator on me, but the correlation coefficient is how well the line of best fit goes with the data, and the data points on the graph look like they match the line. The closer the correlation coefficient is to 1 or -1, means that it has a strong correlation coefficient. It's negative because the slope of the line is negative. If you really want to make sure, you can plug it into a graphing calculator in STAT.
I think the length of pool in inches is actually 12*12=144 because there are 12 inches in a foot.
Also, the scale factor would be 144/16 = 9.
Answer/Step-by-step explanation:
<u><em>George: </em></u>
4.3% ÷ 100 = 0.043
0.043 × 5000 = 215
<em><u>John:</u></em>
4% ÷ 100 = 0.04
0.04 × 5500 = 220
<u><em>End of 6 years:</em></u>
George: 215 × 6 = 1290
John: 220 × 6 = 1320
<u><em>John has earned the most interest at the end of 6yrs.</em></u><u><em> $1320</em></u>
Answer:
c
Step-by-step explanation:
Radius of design= 18 in
Area of design= pi*r^2
= 3.14*324
= 1017.36 sq. in
1017.36/144
= 7.065 sq. ft
7.065*35
= 247.275
Therefore, the cost of building the design costs $247.275 to make
