Answer:
a) 47.7%
b) 87.2%
Step-by-step explanation:
Find the ratio of interest, and convert it to a percentage.
<h3>a) </h3>
(messy right-handed writers)/(right-handed writers)
= 31/65 = 31/65 × 100% ≈ 47.7%
__
<h3>b) </h3>
(neat right-handed writers)/(neat writers)
= 34/39 = 34/39 × 100% ≈ 87.2%
Y=1.09(x-1)+1.49 where y is cost and x is in pounds we could further operate:
y=1.09x-1.09+1.49
y=1.09x+0.4 (note that the domain is x≥1)
Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
7. What I did is divide 520 by 8 to get the miles and hour. I got 65. Since you can get 65 miles and hour, i divided 455 by 65 to get 7.
