Erik is performing a marble experiment in math class. His teacher places an equal number of black, red, and white marbles in a bag. Then, Erik randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first four times Erik takes out a marble, he gets a black marble.

A. What is the theoretical probability of Erik picking a black marble next time? Based on Erik's results, what is the experimental probability of Erik picking a black marble next time?

B. Explain the difference between the two probabilities you found in part A.

C. What is the theoretical probability and likelihood of getting four black marbles in a row?

Answers

Answer 1
1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity

2. experimental considered previous trials and theoretical did not

3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16

x = 16.2

5w+60=52??????????????????????????????

Answers

Subtract 60 from both sides to cancel it out. Now you have 5w=-8. Now divide 5 from both sides to cancel that out. Now you have w=-1.6.

---

hope it helps

Answer:

w = -1.6

Step-by-step explanation:

Subtract 60 from 52. (-8)

You get 5w=-8.

Divide 5 by -8 to get w by itself. (-1.6)

To find if this is correct, do (5x-1.6)+60. (-8+60)

You get 52, therefore, w = -1.6

At what value of x does the graph of the following function F(x) have a
vertical asymptote?

F(x)= 1/x+2

A. 2.
B. -2
C. -1
D. 0

Answers

Answer:

B

Step-by-step explanation:

Given

f(x) = [tex]\frac{1}{x+2}[/tex]

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

x + 2 = 0 ⇒ x = - 2

The equation of the vertical asymptote is x = - 2

Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea. How much milk in liters is required to fill the jug

Answers

Answer:

1.33 liters of milk are required to fill the jug.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the amount of milk required to fill 1 jug of tea given that Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea:

1/6 f a liter of milk → 1/8 of a jug of tea

           x                ←  1 jug of tea

x=(1/6*1)/1/8

x=(1/6)/(1/8)

x=(1*8)/(6*1)

x=8/6

x=4/3=1.33

According to this, the answer is that 1.33 liters of milk are required to fill the jug.
