A card is drawn from a well shuffled deck of 52 cards
Probability of (drawing a card) =
Total number of cards = 52
Number of spade = 13
Number of heart = 13
Probability ( drawing a spade) =
Probability ( drawing a heart) =
probability of drawing a spade or a heart =
= =
<u>Corrected Question</u>
The function is:
Answer:
(a)$48.02
(b)$656,299.92
Step-by-step explanation:
(a) We are to determine the change in monthly revenue if the monthly expenditure, x is raised from its current level of 6000 to 6001.
Therefore, the expected change in monthly revenue
=$48.02
(b)When the amount spent on advertising is $6000
The formula for the surface area of a triangle pyramid is shown below:
SA = A + (3/2)Bh
Where SA for surface area, A=base are, b=base and h=height.
We can solve for surface are since all values needed are given.
SA = (0.07) + (3/2)*1.2*0.75
SA=1.42 square foot
Therefore, the surface area is 1.42 square foot.
It actually depdens on which one you set for x and y
let's say that x=number of televisions sold
y=number of copmuter sold
72x+90y=profit
wants to make at least 360
72x+90y≥360
graph
one way is to find the x and y intercepts, first solve for '=' and not '≥'
x intercept, set y=0
72x=360
x=5
x intercept at (5,0)
yintercept
set x=0
90y=360
y=4
yiint at (0,4)
garph the points (5,0) and (0,4) and connect those points with aline
see witch side to graph one
is (0,0) in the solution set?
0≥360
false
it is not
shade on the side that it isn't on
we have
90x+72y≥360
that underline tells us that (0,5) and (4,0) are possible solutions
hmm
see each
the answer is A, if we do x=computers and y=TV, then D is also acceptable
answer is A
