Answer:
2197 mosquitos
Step-by-step explanation:
If we assume that the colony grows at a constant exponential rate of 30%, we can then multiply 1300 by 30% and add that to our original 1300, and we get 1690. If we do that one more time for 3 days, we get 2167 mosquitos.
Its been a slight while since I have done probibility, but from what I remember, I came op with the answer of a 2.3% probability that all of her friends would be able to come to the lunch she plans on the 4 different days.
1/2 - 5/13 = 3/26 = 0.115
Because: 1/2 - 5/13 = 1 x 13 ÷ 2 x 13 - 5 x 2 ÷ 13 x 2 = 13/26 - 10/26
13/26 - 10/26 = 13 - 10 ÷26 = 3/26 or 0.115.

Answer:
30 seconds
Step-by-step explanation:
Find the total distance needed to be traveled. 520-250 = 270
Find combined rate. 4+5=9
Divide distance needed to be traveled by combine rate to get answer.
270/9 = 30.
Answer: -5.428
Step-by-step explanation:
33 + 5 + 7z = 0
38 + 7z = 0
7z = -38
z = -38/7
