There are 13 diamonds in the deck, so
ways of drawing 3 diamonds.
There is a total of
ways of drawing any 3 cards from the deck.
So the probability of drawing 3 diamonds is

where
.
Answer:

Step-by-step explanation:
Add them all up 15 if one is taken out and no replaced OR put back in, then the second draw will have 14 beads.
4 x 6 = 24
15 x 14 = 210
49/12
Just mulitply the top and the bottom across.
7*7/4*3
49/12
Answer:
a=10, b=5, c=2, d=12
Step-by-step explanation:
Multiply each variable together
5*2=10
8*3=24
10
/24x
the coefficients (numbers) can each be divided by 2
5
/12x
subtract the "x" exponents together
5
/12
Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50
