3/19
There are now 4-1 red beans (3) and 20-1 total beans (19) so 3 out of 19 are red meaning you have a 3/19 chance of getting a red bean

C. 3/19
20 in total. If 1 is taken out, you will have 19. There is a total of 3 red beans left. So the chance of getting a red jellybean is 3/19

Organisms A and B start out with the same population size. Organism A's population doubles every day. After 5 days, the populati
Zigmanuir [339]

Answer:

The number of times organism B's population is larger than organism A's population after 8 days is 32 times

Step-by-step explanation:

The population of organism A doubles every day, geometrically as follows

a, a·r, a·r²

Where;

r = 2

The population after 5 days, is therefore;

Pₐ₅ = = 32·a

The virus cuts the population in half for three days as follows;

The first of ta·2⁵ he three days = 32/2 = 16·a

The second of the three days = 16/2 = 8·a

After the third day, Pₐ = 8/2 = 8·a

The population growth of organism B is the same as the initial growth of organism A, therefore, the population, P₈ of organism B after 8 days is given as follows;

P₈ =  a·2⁸ = 256·a

Therefore, the number of times organism B's population is larger than organism A's population after 8 days is P₈/Pₐ = 256·a/8·a = 32 times

Which gives, the number of times organism B's population is larger than organism A's population after 8 days is 32 times.

Susan and terry run a day care center Since they use susans house it was agreed that her share is twice as Terrys if they earn 2
Nadya [2.5K]
The easiest way to do this is to divide 225 by 3, so 225 / 3, and what you get as the sum, in this case it's 75, you would multiply the sum by 2, which equals 150, and that, would be Susan's share. So... 225 / 3 = 75. 75 * 2 = 150. $150 is the amount Susan gets. Hope this helps!
