Answer:
12.81%
Step-by-step explanation:
2600-5500=20500
20500/16=1281.25
1281.25/100= 12.8125
rounded 12.81%

Step-by-step explanation:
The train uses

If you reduce that you get that the train uses

To find the slope of the line, we will use the 2 points on the coordinate plane where the graph goes through: (0, 0) and (400, 200)
Applying the slope formula:

Answer:
D. <F = 65 degrees
Step-by-step explanation:
First off, we know that the measures of <F and the angle adjacent to it add to 90 degrees, as indicated by the right angle. They are complementary angles.
The complementary angle of <F has an intercepted arc of 50 degrees. Because the angle is on the opposite end of the circle, it is half of the measure of the arc. Therefore, it is 25 degrees.
Because this angle and <F sum to 90, just subtract 90-25 to find <F.
<F = 65 degrees
The best way to create your frequency table is to look at each number and place a tally in the correct interval it belongs.
After all numbers have been tallied, count the tally marks and write a number.
These numbers will represent how high the bars will be on your histogram.
Please see the attached picture for the work that goes along with the above explanation. You should always count your totals to make sure the numbers match.
Since there are a total number of 15 members participating, you would divide 150 by 15 since everyone would get their fair share. Next you would multiply 10 by 9 which would result to $90 and the profit the math club received
