Answer:
-11/15 is the greatest because ita in negative
The required percentage error when estimating the height of the building is 3.84%.
<h3>How to calculate the percent error?</h3>
Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
Given that,
An estimate of the height, H meters, of a tall building can be found using the formula :
H = 3f + 15
where the building is f floors high.
f = 85
The real height of the building is 260 m.
H = 3f + 15
Put f = 85 in the above formula
H = 3(85) + 15
H = 270 m
Error,

So, the required percentage error is 3.84%.

Answer: y = −2
Step-by-step explanation:
- 0 = −4x − 2
- x = −1/2
- To find the y-intercept, substitute in 0 for x and solve for y. Y = − 4 * 0 −2
- Which then gives you y = - 2
