John is watching an old game show rerun on television called let's make a deal in which the contestant chooses a prize behind one of two curtains. behind one of the curtains is a gag prize worth $150, and behind the other is a round-the-world trip worth $7,200. the producer of the game show has placed a subliminal message on the curtain containing the gag prize, which makes the probability of choosing the gag prize equal to 75 percent. what is the expected value of the selection, and what is the standard deviation of that selection?

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer is : muchas/tipicas

have a nice day!

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
