Answer:
20
Step-by-step explanation:
u-t = 2
u+t= 5
(u-t) (u²-t²)
(u-t) (u-t) (u+t) (a²-b²= (a+b) (a-b))
put the values
(2)(2)(5)
=20
Answer:
(-3,-3)
Step-by-step explanation:
If we reflect P (0,0) across x=-3 and then across y=-3, then the new point of P would be (0-3,0-3)=(-3,-3)
Answer:
The probability that a car that comes into the garage needs both an oil change and a tire rotation is
.
Step-by-step explanation:
The conditional probability of an event <em>B</em> given that another event <em>A</em> has already occurred is:

Denote the events as follows:
<em>X</em> = cars brought in for service need an oil change
<em>Y</em> = cars brought in for service need a tire rotation
The information provided is:


Compute the value of P (X ∩ Y) as follows:




Thus, the probability that a car that comes into the garage needs both an oil change and a tire rotation is
.
10 - 4 = 6ounces
6 × 0.65 = $3.90
3.90 + 1.25 = $5.15
it costs $5.15 to mail a package that weighs 10oz
