Equation can be used to find x is 60/55 + 60+x = 2.75
The time of going to rink is 2.75
We know,
speed = distance/time
⇒ Time = distance / speed
<h3>How to solve?</h3>
(1) Way to rink
Given :
Distance = 60 miles
Speed = 55 miles per hours,
⇒ Time taken by him = Distance / speed = 60/55 hours
(2) Way to home
Given : Distance = 60 miles
Let Speed be x,
⇒ Time taken by him = distance/speed = 60/x hours
Total time taken = 60/55 + 60+x
According to Question, Total time = 2.75 hours,
Thus, 60/55 + 60+x = 2.75 is the required equation.

Answer:
x³ - 12x² + 43x - 40
Step-by-step explanation:
f(x) × g(x)
= (x - 5)(x² - 7x + 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² - 7x + 8) - 5(x² - 7x + 8) ← distribute both parenthesis
= x³ - 7x² + 8x - 5x² + 35x - 40 ← collect like terms
= x³ - 12x² + 43x - 40
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.
<h3>What is the margin of error?</h3>
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,
Hence, the Margin of error in this survey is 1%.
