Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65

Answer:
27/4
Step-by-step explanation:
2x + 8 - 8y
2x - 8y + 8
2 * (1/8) - [ 8 * (3/16)] +8
(1/4) - (3/2) + 8
A.) For 25 ≤ d ≤ 150;
ΔT/Δd = (5.50 - 5.50)/(150 - 25) = 0/125 = 0
b.) For 25 ≤ d ≤ 75;
ΔT/Δd = (5.10 - 5.50)/(75 - 25) = -0.4/50 = -0.008
c.) For 100 ≤ d ≤ 200;
ΔT/Δd = (6.00 - 5.10)/(200 - 100) = 0.9/100 = 0.009
Answer: The answer is 31.25 because The mean of 16 items was found to be 30. So once you checked, it was that 2 items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Sum = mean no of items = 30 16 = 480
(32 +28) – (22 + 18) = 20
Correct mean = = 31.25
