<span>Experimental probability is defined as the
ratio of the number of times an event occurs to the total number of
trials the activity is performed
In this case the number that the event occurred is 8 and the number of trials is 50, so the ratio is 8/50 = 4/25.
Then the answer is option B: 4/25

a) 170.00 =8n -30
200= 8n
n = 200/8 = 25 items
b) since the expenses increased the profits would decrease
profit = 8(25)-40 = 200-40 = 160
170-160 = 10.00
profit decreased by $10.00
Answer:
28 million college students.
Step-by-step explanation:
We can represent all college students as x. This means that all part-time college students are
. Because all part-time college students are also equal to 8.6 million, we have
. To find the number of total college students, or x, we have to multiply by 100/31 to get rid of the fraction on the other side:

The left side of the equation evaluates as
. Because we are asked to round to the nearest million, we have to round to 28 million, which is the closest.
Answer:
The range would not change
Step-by-step explanation:
If we replaced one of the 7s with a 5, we still have a 7. The range will be the highest number minus the lowest number (7 - 1 = 6). So the range would still not change because we still have another 7.
I think it would require 100 workers since 1 worker digs up 1 yard.
Hope this helps.
