225*(x+1/25)+225*(y-4/9)=225*1
9(x+1)+25(y-4)=225
9x+9+25y-100=225
9x-91+25y=225
9x=225+91-25y
9x=316-25y
x=316/9-25/9
Answer:
0.979%
Step-by-step explanation:
Given that:
Estimated value = 825 ;
Actual value = 817
Percentage error:
(|Estimated value - Actual value| ÷ actual value) * 100%
(|825 - 817| ÷ 817) * 100%
(8 / 817) * 100%
0.0097919 * 100%
= 0.979%
= 1% (nearest percent)

Answer:
B
y = 3 cos (pi/12x - pi/4) + 17
Step-by-step explanation:
First find the average temperature which is 20 + 14/2 = 17
Find the amplitude
20 - 17 = 3
This means that that at noon, the shift is 3hrs past
