Assuming you're concerned with interest rate problems, r is generally involved in something like the formula ...
... i = prt
So, r will have the units of ...
... r = i/(pt) = (dollars)/(dollars·year) = 1/year
That is, r is <em>(some fraction) per year</em>.
_____
Often, the fraction is expressed as a percentage. The fraction will be unitless (as percentages are), leaving the units of r as year⁻¹.
For the first one, the graph shows a total of 12 representatives across all 5 categories, and of those, 2 are from the west this is the fraction 2/12, or the answer A) 1/6, meaning that 1 in 6 of the representatives are going to be from the western region.
For number 2, the answer is A) If you flip a coin 800 times, heads will come up about 400 times. This is because the law of large numbers says that as the number gets larger the ratio will get closer to 1:1. This means that since the coin only has 2 sides, it is about 50/50, meaning that of 800, 400 would be heads and 400 would be tails.
Hope this helps! :D

Answer:

Step-by-step explanation:

Answer:
Part A) x = 5
Part B) B = 113 degrees, C = 95 degrees. E = 95 degrees
Step-by-step explanation:
<u>Part A:</u>
We know that the sum of all angles in a pentagon are 540 degrees.
We already have two angles: 113 and 124 which add up to 237.
Make an equation out of all the information.
237 + 98 + 3x + 19x - x = 540
3x + 19x - x = 105
21x = 105
x = 5
<u>Part B:</u>
Substitute 5 for each x
measure B: 98 + 3x = 98 + 3*5 = 98 + 15 = 113
measure C: 100 - x = 100 - 5 = 95
measure E: 19x = 19* 5 = 95
