Answer:
if what? come on
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
P(A)=0.3
P(B)=0.1
P(A)×P(B)=0.3×0.1=0.03
P(A and B)=P(A)×P(B)
They are independent.
0.9 is the answerrrrrrrrrrrrrr
(A) For x representing the cost of one of Tanya's items, her total purchase cost 5x. The cost of one of Tony's items is then (x-1.75) and the total of Tony's purchase is 6(x-1.75). The problem statement tells us these are equal values. Your equation is ...
... 5x = 6(x -1.75)
(B) Subtract 5x, simplify and add the opposite of the constant.
... 5x -5x = 6x -6·1.75 -5x
... 0 = x -10.50
... 10.50 = x
(C) 5x = 5·10.50 = 52.50
... 6(x -1.75) = 6·8.75 = 52.50 . . . . . the two purchases are the same value
(D) The individual cost of Tanya's iterms was $10.50. The individual cost of Tony's items was $8.75.
The answer is A because if you do the 40 dagree and a coodinate plane it forms a triangle.
