Answer:
141.46 mi/h
Step-by-step explanation:
d = rt
r = d/t = (2440.2 mi)/(17.25 h) ≈ 141.46 mi/h
The woman's average speed was about 141.46 mph.
Answer:
11.6 cents per hour.
Step-by-step explanation:
To find the rate per hour we divide the money paid by the number of hours: $82.50/712 = $0.116 per hour or 11.6 cents per hour.
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the formula for calculating relative frequency
![Relativefrequency=\frac{number\text{ of required events}}{number\text{ of total events}}](https://tex.z-dn.net/?f=Relativefrequency%3D%5Cfrac%7Bnumber%5Ctext%7B%20of%20required%20events%7D%7D%7Bnumber%5Ctext%7B%20of%20total%20events%7D%7D)
STEP 2: Calculate the relative frequency
![\begin{gathered} number\text{ of club}=12 \\ number\text{ of total cards}=52 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20number%5Ctext%7B%20of%20club%7D%3D12%20%5C%5C%20number%5Ctext%7B%20of%20total%20cards%7D%3D52%20%5Cend%7Bgathered%7D)
By substitution,
![Relative\text{ }frequency=\frac{12}{52}=\frac{3}{13}](https://tex.z-dn.net/?f=Relative%5Ctext%7B%20%7Dfrequency%3D%5Cfrac%7B12%7D%7B52%7D%3D%5Cfrac%7B3%7D%7B13%7D)
The relative frequency in a fraction in its simplest form is 3/13
it's the first 1 ~~~~~~~~~~~~~
