The answer is 8.5. you simply take the worded equation above and turn it into a math problem (a+-6) x 4
You can simplify by adding the like terms which would be -8n and 5n and you get -13n so the simplified version would be -13n+4
This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence:
If a1=1.6 then:
The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
To find this question, you first should put your data values in order from least to greatest. Doing so would look like this:
3, 39, 39, 40, 46, 48, 60, 62, 62
Now find the median, the middle number. This would be 46. This would also be the middle point on your box and whisker plot. Looking at your answer choices, the only one that has the middle point at 46 is the last one. So that is your answer.
t = number of tickets
15t ≥ 1500
so....
step 1. 15t ≥ 1500 --> divide both sides by 15 --> 15t/15 ≥ 1500/15
step 2. t ≥ 100
So 100 at the least, ticket should be sold to reach atleast $1500.
I hope this helps. :)
