Cards are drawn with replacement from a standard deck until a king is drawn. does this constitute a binomial​ experiment? why or

why​ not? choose the correct answer below.
a. ​yes, because there are three independent draws. for each draw there are two outcomes​ (king and not​ king) and a constant probability of getting a king.
b. ​no, because there is not a fixed number of trials.
c. ​no, because there are more than two outcomes each time a card is drawn.
d. ​no, because the probability of getting a king will change from one trial to the next.

Given :Cards are drawn with replacement from a standard deck until a king is drawn.For each trial there are 13 possible outcomes.If we consider binomial experiment there will be  two outcomes. The cards are drawn with replacement that is the number of outcomes are not independent.This does not fulfill property of binomial  experiment .

A binomial experiment is a statistical experiment that has the following properties: The experiment consists of n repeated trials. Each trial can result in just two possible outcomes

Among the given options ,Option  b. ​no, because there is not a fixed number of trials is the right answer.

The two angles are verticals angles so they are congruent, so you can solve for x by writing and solving an equation

6x-82=3x-23

Combine like terms

3x=105

And simplify to get x=35

Oksi-84 [34.3K]

Answer:

x=16/3=5.33.

Step-by-step explanation:

Isolate x on one side of the equation.

2+x3=18

2+x*3=18

2+x*3-2=18-2 (First, subtract 2 from both sides.)

18-2 (Solve.)

18-2=16

x*3=16

x*3/3=16/3 (Then, divide by 3 from both sides.)

16/3=5.33

x=16/3=5.33

In conclusion, the final answer is x=16/3=5.33.

Solve the right triangle. 34.5 Find the length of the side opposite to the given angle. (Round your answer to two decimal places
lapo4ka [179]

Answer:

a) 388.03

b) 148.49

c) π/8

Step-by-step explanation:

Find the diagram attached

Let the opposite side be y

Given

a) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

sin theta = opposite/hypotenuse

sin 67.5 = y/420

x = 420sin67.5

x = 420(0.9238)

x = 388.03

Hence the length of the side opposite to the given angle is 388.03

b) Hypotenuse = 420

theta = 3π/8 rad

theta = 3(180)/8

theta = 67.5degrees

Using the SOH CAH TOA identity

cos theta = adjacent/hypotenuse

cos 67.5 = x/420

x = 420cos67.5

x = 420(0.3827)

x = 148.49

Hence the length of the side adjacent to the given angle is 148.49

c) The sum of angle in the triangle is π

Let the measure of the unknown angle be z

z + 3π/8 + π/2 = π

z + 3π+4π/8 = π

z + 7π/8 = π

z = π - 7π/8

z = (8π-7π)/8

z = π/8

Hence the measure of the other acute angle is π/8
