Flip two coins 100 times, and record the results of each coin toss in a table like the one below:
monitta

Answer:

1)The theoretical probability that a coin toss results in two heads showing is 25%.

2)The experimental probability that a coin toss results in two heads showing is 44%.

3) The theoretical probability that a coin toss results in two tails showing is 25%.

4) The experimental probability that a coin toss results in two tails showing is 34%.

5) The theoretical probability that a coin toss results in one head and one tail showing is 50%.

6) The experimental probability that a coin toss results in a head and a tail is 22%.

7) The experimental probabilities are slightly different from the theoretical probabilities because the number of experiments is relatively small. As the number of experiments increase, the experimental probabilities will get closer to the theoretical probabilities.

Step-by-step explanation:

Probability:

What you want to happen is the desired outcome.

Everything that can happen iis the total outcomes.

The probability is the division of the number of possible outcomes by the number of total outcomes.

Theoretical Probability:

The results you expect to happen.

Experimental Probability:

The probability determined from the result of an experiment.

1. What is the theoretical probability that a coin toss results in two heads showing?

In each toss, the theoretical  probability that a coin toss results in a head showing is 50%.

So for two coins, the probability is:

P = (0.5)^{2} = 0.25

The theoretical probability that a coin toss results in two heads showing is 25%.

2. What is the experimental probability that a coin toss results in two heads showing?

There were 100 flips, and it resulted in two heads 44 times, so:

P = \frac{44}{100} = 0.44

The experimental probability that a coin toss results in two heads showing is 44%.

3. What is the theoretical probability that a coin toss results in two tails showing?

In each toss, the theoretical  probability that a coin toss results in a tail showing is 50%.

So for two tails, the probability is:

P = (0.5)^{2} = 0.25

The theoretical probability that a coin toss results in two tails showing is 25%.

4. What is the experimental probability that a coin toss results in two tails showing?

There were 100 flips, and it resulted in two tails 34 times, so:

P = \frac{34}{100} = 0.34

The experimental probability that a coin toss results in two tails showing is 34%.

5. What is the theoretical probability that a coin toss results in one head and one tail showing?

In each toss, the theoretical probability that a coin toss results in a tail showing is 50% and in a head showing is 50%.

They can be permutated, as the tail can appear before the head, or the head before the tail. So:

P = p_{2,1}*(0.5)*(0.5) = \frac{2!}{1!}*0.25 = 0.50

The theoretical probability that a coin toss results in one head and one tail showing is 50%.

6. What is the experimental probability that a coin toss results in one head and one tail showing?

There were 100 flips, and it resulted in a head and a tail showing 22 times, so:

P = \frac{22}{100} = 0.22

The experimental probability that a coin toss results in a head and a tail is 22%.

Use simple interest to find the ending balance.<br> 1) $47,000 at 14.2% for 2 years
Nastasia [14]

Answer:

60348

Step-by-step explanation:

47000 x .142 = 6674

6674 x 2 = 13348

47000 + 13348 = 60348

A soccer player kicks a ball with an initial velocity of 35 feet per second from a starting point of 0 feet. Use the equation h(
tamaranim1 [39]

Answer:

2.2 seconds

Step-by-step explanation:

h(t)=-16t^2+bt+c

We know the initial velocity is 35  = b

We know the initial height is 0 =c

h(t)=-16t^2+35t+0

h(t)=-16t^2+35t

Question 1 is to find when the ball hits the ground  or when h(t) is 0

0=-16t^2+35t

Factor out a t

0 = t( -16t+35)

We can use the zero product property  to solve for t

t=0   -16t+35 =0

          Subtract 35 from each side

         -16t = -35

          Divide by -16

          -16t/-16  = -35/-16

                t = 2.1875 seconds

t=0 is when the ball is kicked

t =2.1875 is when the ball lands on the ground after being kicked

Rounded to the nearest tenth

2.2 seconds

19.1 ft

The maximum height is at the axis of symmetry

h = -b/2a

  -35/(2*-16)

  -35/-32

  35/32

This is the t value

To find the maximum height , we need to put this in the equation to find the y value

h(35/32) = -16( 35/32)^2 + 35 *(35/32)

             = -16* 1.196289 +38.28125

               19.140625 ft

Rounding to the nearest tenth

19.1 ft

Jayden is SCUBA diving 6 feet below the sea level and swims 4 feet upwards.
algol [13]
Swim 2 more feet up to reach the surface cos 4+2 is 6 so after swimming up the extra 2 feet he would have emerged from the surface of the water since he has initially already gone up 4 feet after now swimming 6 feet.
