Answer:

Step-by-step explanation:

The total number of ducks in the pond is 75. 25 ducks are marked as a winner.

Probability is expressed as number of possible outcomes/total number of outcomes.

if you take 2 ducks out but don't replace them, the probability that the first duck that you took out is a winner is

25/75 = 1/3

The total number of ducks left would be 74 and the number of winners would be 24.

the probability that the second duck that you took out is a winner is

24/74 = 12/37

Therefore, the probability that both are winners is

1/3 × 12/37 = 4/37

Answer:

<1 = 114° and <2 = 66°

Step-by-step explanation:

The two angles measure 66 degrees and 114 degrees because the sum of supplementary angles is 180 degrees.

Explanation:

Supplementary angles are two angles with a sum of 180 degrees.

Let the smaller angle = x

If the two angles differ by 48 degrees, the bigger angle is 48 degrees more and equals

x+48

.

The sum of the two angles is 180, so...

x+x+48=180

Add the variableterms

2x+48=180

Subtract 48 from both sides

2x=132

Divide both sides by 2

2x/2=132/2

x=66

This is the measure of the smaller angle.

The bigger angle = x+48=114

What is the arc length of the subtending arc for an angle of 72 degrees on a circle of radius 4?​
wolverine [178]

Step-by-step explanation:

We can set up the ration of the radian angle θ in your problem in terms of degrees given as the ratio: (Θ/2·pi) = (72/360), solving for Θ we get Θ = 1.26 radians. Then for the arc length s = Θ·r using this value gives s = 1.26·4 = 5.04

What is the shaded area?
spin [16.1K]

Answer:

The total area (including the area of the circle) would be 16 × 16 = 256 square centimetres.

The area of the circle would be (taking the value of pi as 3.14) is 200.96 square centimetres

The area of the shaded region would be 256 - 200. 96 = 55.04 square centimetres
