You recorded the weekly distance you bicycled in miles and computed the standard deviation to be s= 3.1 miles. your friend wants to know the standard deviation in kilometers. Do you need to redo all the calculations?

No need to redo all the calculations. we use the given standard deviation. We convert the given standard deviation miles into kilometers.

Given 1 mile ≈ 1.6 kilometers

So 3 miles = 1.6 * 3.1 = 4.96 kilometers

standard deviation = 4.96 kilometers.

A plumber charges a $55 house call fee and an additional $42 an hour. He fixes the pipes in your building and charges $265. Solv
Elina [12.6K]

Answer:

Step-by-step explanation:

You haven't given the equation, but I can make one up.

Cost = 55 + 42*h

So let the cost = 265 dollars

265 = 55 + 42h             Subtract 55 from both sides

210 = 42h                      Divide both sides by 42

210/42 = 42h/42

h = 5

He worked 5 hours.

How to slove this: x-5/3=x-3/5
sladkih [1.3K]

Answer: There are no solutions.

Step-by-step explanation:  x - 5/3 = x - 3/5

                                               x + -5/3 = x + -3/5

                                              x + -5/3 - x = x + -3/5 - x

                                             -5/3 = -3/5

                                             -5/3 + 5/3 = -3/5 + 5/3

                                              0 = 16/15
