Answer: probability = 0.506
Step-by-step explanation:
The data we have is:
Total people: 205 + 160 + 40 = 405
prefer cats: 205
prefer dogs: 160
neither: 40
The probability that a person chosen at random prefers cats is equal to the number of people that prefer cats divided the total number of people:
p = 205/405 = 0.506
in percent form, this is 50.6%
Answer:
A, C
Step-by-step explanation:
When you put the equation y = x -12 into a TI-84 calculator (because it has graph) and go to the table you can see that B,D,E don’t have the same y-axis even though their x-axis is the same but the y-axis isn’t, therefor A and C is the correct answer.
Sorry not the best explanation but I hope it helps
Answer:
y-intercept: (0,6)
slope = -2
equation: y = -2x + 6
Step-by-step explanation:
1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.
2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula 
and solve:
So, the slope is -2.
3) With the found information, use the slope-intercept formula 
to write the line's equation. Substitute values for the 
and 
.
represents the slope, so substitute -2 in its place. represents the y-intercept, so substitute 6 in its place. This gives the following equation:
Answer:
40 miles.
Step-by-step explanation:
Given that the cost of renting a car in Hertz is $ 15 per day plus $ 0.50 for each mile traveled, while in Enterprise the cost is $ 25 per day plus $ 0.25 per mile traveled, to determine how many miles should be traveled to incur the same expenditure in both companies the following calculation must be made:
25 - 15 = 10
0.50 - 025 = 0.25
10 / 0.25 = 40
Therefore, to incur the same cost, 40 miles must be traveled, which is verified with the following calculation:
25 + 0.25 x 40 = 35
15 + 0.50 x 40 = 35
