Answer:

the dependent variable <em>depends </em>on the independent variable

thus, p is dependent on t, p is the dependent variable, and t is the independent variable (B)

every month, Gloria paints 2 pieces

each month, t is increased by 1, and p is increased by 2 (C)

every month, Gloria paints 2 pieces

Forty tickets are sold for a raffle with two prizes. You buy two tickets. What is the probability that you will win both prizes
tekilochka [14]
When you first pick a ticket, there are 2 winning tickets and 40 total tickets.  This means that there is a 2/40 chance of your ticket being a winning one.  This fraction can be reduced to 1/20.

After this, there will be 1 winning ticket left and 39 total tickets.  There is a 1/39 chance of the next ticket being a winning one.  We multiply these two fractions together to get our answer.  1/20 * 1/39 = 1/780, so there is a 1/780 chance of having 2 winning tickets.

Agata [3.3K]

Answer:

hence cos ( 2 A ) = cos 2 A − ( 1 − cos 2 A ) = 2 cos 2 A − 1


Step-by-step explanation:Well we know that for two angles A , B

it holds that cos ( A + B ) = cos A cos B − sin A ⋅ sin B hence for A = B you get cos ( 2 A ) = cos 2 A − sin 2 A But sin 2 A = 1 − cos 2 A
