Answer:
D and E.
Step-by-step explanation:
D. For each toss you either get a head or a tail , 2 outcomes, so for 4 tosses the number of outcomes = 2*2*2*2 = 16.
E. As it is a fair coin all outcomes are equally likely.
Answer: x = 20
Step-by-step explanation:
1) Move all terms to the left:
x-13-(x/2-3)=0
2) Get rid of parentheses
x-x/2+3-13=0
3) Multiply all the terms by the denominator
x*2-x+3*2-13*2=0
4) Add all the numbers together, and all the variables
-1x+x*2-20=0
5) Multiply elements
-1x+2x-20=0
6) Add all the numbers together, and all the variables
x-20=0
7) Move all terms containing x to the left, all other terms to the right
x=20
Hope This Helps (From My Notes)
Caroline is correct because the equation y = (x-1)(x-5) is in factored form. If you solve the terms (x-1) and (x-5), you get the zeros (aka x-intercepts) of the graph.
Solve (set the terms equal to 0):
x-1 = 0 x = 1
x-5 = 0 x = 5
∴ the x-intercepts are (1,0) and (5,0).
The purple graph corresponds to the zeros in the equation, not the green graph. The green graph has negative x-intercepts, whereas the purple graph has positive x-intercepts like in the equation.
The answer is B, they are paid based on a salary not amount of hours worked.
