Answer:

Any of these, given the equation

Step-by-step explanation:

a+9a−3 > 2

Combine like terms

10a−3 > 2

Add 3 to each side

10a−3+3 > 2+3

10a > 5

Divide each side by 10

10a/10 >5/10

a >1/2

Step-by-step explanation:

cranberries, oranges and lemon extracts makes =96 fluid Ounces of mock-tail

i.e cranberries+oranges+lemon extracts=96 fluid Ounces of mock-tail....... (1)

  • let fluid ounces of orange=x
  • then fluid ounces of cranberry=3x; \\ because it is three times of orange
  • and lemon extract is given as 24 ounces.

putting these values in (1), we get

3x+x+24=96

4x+24=96\\4x=96-24\\4x=72\\x=\frac{72}{4}\\ x=18

fluid Ounces of orange juice was used in all=18

g A law firm has six senior and seven junior partners. A committee of three partners is selected at random to represent the firm
expeople1 [14]

Answer:

133/143

Step-by-step explanation:

Let S be the sample space

Let E be the event of selecting three committee partners with at least one junior partner.

Partners in the law firm include:

Senior partners = 6

Junior partners = 7

Total partners = 13

n(S) = number of ways of selecting 3 partners from 13 = 13C3

n(S) = 13C3 = 13!/(10!3!) = (13x12x11)/(3x2x1) = 286

To get n(E) i.e least 1 junior partner in the selected committee, we may have:

(2 senior and 1 junior) or ( 1 senior and 2 junior) or (3 junior).

Therefore, the required number of way is given below:

= (6C2 x 7C1) + (6C1 x 7C2) + 7C3

= [(6x5)/2 x 7] + [6 x (7x6)/2] + [(7x6x5)/(3x2)]

= 105 + 126 + 35

n(E) = 266

Therefore, the probability P(E) that at least one of the junior partners is on the​ committee is given below:

P(E) = n(E) /n(S)

P(E) = 266/286

P(E) = 133/143
