Speed is expressed as the ratio of distance/time = d/t
in Alex's case, speed = (3.8 miles / 18 minutes)
. . . or simply
3.8/18

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 5(2 - x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-1) = 5(2 - -1)
- (Parenthesis) Subtract: f(-1) = 5(3)
- Multiply: f(-1) = 15
Answer:
A Histogram is a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval "
Here we take a width of 2 units on the bar graph i.e. we consider the interval 0-2, 2-4, 4-6 and so on.
Now we arrange our table in these intervals with the help of the given quantities.
Step-by-step explanation:
The greatest factor of 60 and 75 is 15.
Reasoning: I found the factors and prime factorization of 60 and 75. The biggest common factor number is the GCF number. So the greatest common factor 60 and 75 is 15.
