Step-by-step explanation:

Angle G = 180° - 48° - 75° = 57°

By Sine rule, FG/sinD = DG/sinF = DF/sinG.

Hence DF = 22.57 units and DG = 25.99 units.

Answer:

DF ≈ 22.6 units

DG ≈ 25.9 units

Step-by-step explanation:

1st step is to get the ∠G

∠G = 180 - 48 - 75
∠G = 57°

2nd step is by using law of sines

DF = DG = FG

sin G sin F sin D

solve for side DF

DF = FG

sin G sin D

DF = 20

sin(57) sin(48)

DF * sin(48) = 20 * sin(57)

DF = 20 * sin(57)

sin(48)

DF ≈ 22.6 units

solve for side DG

FG = DG

sin D sin F

20 = DG

sin(48) sin(75)

DG * sin(48) = 20 * sin(75)

DG = 20 * sin(75)

sin(48)

DG ≈ 26 units

Answer:

y=7

x=-7

Step-by-step explanation:

2(-3x - 7y )= 2(-28)

3(2x+ 3y)=3(7)

-6x - 14y = -56

6x + 9y = 21

Add the two equations

-1(0x - 5y)= -1(- 35)

5y = 35

Divide both sides by 5

y=7

Substitution

6x + 9(7) = 21

6x + 63 = 21

Subtract 63 from both sides

6x = -42

Divide both sides by 6

x= - 7

The easiest way to solve this problem is to make a table, based on 100 total person

 Prefer week ends Prefer week days Total

Female 10 55 65

Male 15 20 35

Total 25 75 100

The bold numbers are conclusions. The plain numbers are data.

The probability that a randomly selected club member is female, given that that person prefers swimming on weekends is [10 / 25] = 0.40

Answer: option D. 0.40

Here's what I got.

Column C, starting from the top and going down: $12.33, $13.00, $10.50, $10.00, $6.00, $8.00, $4.25, $10.50, $11.50, and $8.50

Column F, Starting from the top and going down: $4,650, $4,650, $4,650, $4,600, $4,600, $4,600, $5,000, $5,000, $4,625, and $4,625.

I don't really understand column G yet, so that's all I have. Hope it helped a little bit.
