Answer: Choice A) $0.45
================================
Explanation:
Plug in d = 0 and you'll have A(d) = 0.45d+180 turn into A(0) = 180. This says that Terry is paid $180 even if he doesnt travel a single mile.
Now plug in d = 1. You should get A(1) = 180.45 as the result.
Subtract the results: 180.45 - 180 = 0.45
He has earned 45 cents or 0.45 dollars for traveling one mile
----------
A shortcut is to notice that the slope of the line is 0.45
It might help to view A(d) = 0.45d+180 as y = 0.45x+180. We see that the equation is in slope intercept form y = mx+b
m = slope = 0.45 tells us how much additional dollars Terry earns for each additional mile traveled
b = 180 = y intercept = starting amount of money Terry is paid, this amount does not change based on how many miles he travels.
Answer:
the solution would be 10 to the best of my knowledge
Conditional probability:
P ( B \ A ) = P ( A and B ) / P ( A )
Probability of an event B given by that A has already occurred.
P ( A and B ) = 0.051
P ( A ) = 0.32
P ( B \ A ) = 0.051 / 0.32 = 0.159375 ≈ 0.159
Answer:
B ) 0.159
<span>We can say that 600 represents 100% and 12 represents x %. Using the proportion: 600 : 12 = 100 : x. That can also be written as: 600/12 =100/x. Then we will multiply across the known corners and then divide by the third number. 600 x = 12 * 100 600 x = 1,200 x = 1,200 : 600, x = 2. Answer: 12 is 2% of 600.</span>
Answer:
200 miles
Explanation:
Here map to actual to scale: 1 inch = 50 miles
- On map distance: 4 inches
To find actual distance, simply multiply map distance by scale factor
Actual Distance : 4 × 50 = 200 miles
