a gas-filled balloon rises 40 feet in the 1st minute, 60 feet in the 2nd minute, and 80 feet in the 3rd minute, how many feet wi

vladimir2022 [97]

Let $g_n$ represent the number of feet that the balloon rises in the $n^{th}$ minute.

so

$g_1=40$ ft , means that in the 1st minute, the balloon rose 40 feet

$g_2=60$ ft, means : in the 2nd minute the balloon rose 60 feet

$g_3=80$

we notice that each minute, the balloon rises a multiple of 20, feet:

$g_1=40=2*20$

$g_2=60=3*20$

$g_3=80=4*20$

so it is clear that $g_n=(n+1)*20$

during the 15th minute the balloon rises $g_1_5=16*20=320$ (feet)

In an aquarium, there are 10 large fish and 5 small fish. Half of the large fish are red.

vfiekz [6]

Answer:

There's 21% of chances

Step-by-step explanation:

Here we have to use the definition of a simple probability, where all fishes has the same probability to be chose.

So, we have to divide the possible outcomes with the total of outcomes. The possible outcomes refer to the number of large-blue fishes, and the total number of outcomes represent the total number of fishes. So

P = 3/4 ≈ 0.21 (or 21%)

Therfore, there's 21% of chances to select one fish randomly and be a large, blue fish.
