A fair coin is flipped 10 times and lands on heads 8 times. Why is there a difference between the experimental and theoretical probabilities of observing 8 heads in 10 coin flips?
A.
Since the number of heads in the 10 coin flips is 8, the theoretical probability of observing a head in a coin flip increases from 0.5 to 0.8.
B.
Since 10 is a large enough number of trials, there is probably some error in the recording of the coin flip outcomes.
C.
The theoretical probability has no basis in reality, so the new probability of flipping heads is now 0.8.
D.
There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.

Answers

Answer 1

Answer:

Step-by-step explanation:

If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is 1 2. This is also the probability of flipping heads on a coin. And so we have: 1 2 × 1 2 × 1 2 = 1 8. If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. sorry if this isn't right have a nice day.

Answer 2

Answer:

There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.

What is the perimeter of this shape

Answers

9514 1404 393

Answer:

  72.6 cm

Step-by-step explanation:

It is the perimeter of the overall rectangle plus twice the depth of the notch.*

  P = 2(L+W) +2d

  P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)

  P = 72.6 cm

The perimeter of the shape is 72.6 cm.

_____

* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.

Step-by-step explanation:

Gentry Industries has the following information about maintenance costs in the past six months.
Month Machine _Hours Amount
January 200 $2,800
February 350 3,000
March 450 4,000
April 500 5,000
May 600 5,200
June 580 5,800
How much would Gentry pay if maintenance machine hours are 550?

Answers

Answer:

Total cost= $5,425

Step-by-step explanation:

Giving the following information:

Month Machine _Hours Amount

January 200 $2,800

February 350 3,000

March 450 4,000

April 500 5,000

May 600 5,200

June 580 5,800

First, we need to calculate the fixed and variable costs. To do it, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (5,800 - 2,800) / (600 - 200)

Variable cost per unit= $7.5 per hour

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 5,800 - (7.5*600)

Fixed costs= $1,300

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 2,800 - (7.5*200)

Fixed costs= $1,300

Now, we can determine the total cost for 550 hours:

Total cost= 1,300 + 7.5*550

Total cost= $5,425

Step-by-step explanation:

In a cheese factory, 4.5-kg blocks of cheese are cut manually. For a large number of blocks, the standard deviation of the cutting process is measured and found to be 0.10 kg. The measurement was done with a scale with an accuracy of 1.5% of the full scale of 12 kg. Calculate the total uncertainty of the weight of the blocks of cheese at a 95 % confidence level.

Answers

Answer:

0.2690 kg

Step-by-step explanation:

Given that:

For cutting a 4.5 kg block of cheese; the standard deviation:

[tex]S_x = 0.1 \ kg[/tex]

For a large no of blocks,  at 95% confidence level;

Using the t table; where the degree of freedom is infinity or > 30

t-distribution (t) = 2

[tex]P_x = tS_x[/tex]

[tex]P_x = 2 \times 0.1[/tex]

[tex]P_x = 0.2 \ kg[/tex]

The system uncertainty as a result of the accuracy [tex]B_x[/tex] is:

[tex]B_x = 1.5\% \ of \ reading[/tex]

[tex]B_x = (\dfrac{1.5}{100})(12 kg)[/tex]

[tex]B_x = 0.18 \ kg[/tex]

The total uncertainty  for a single experiment with a 95% confidence interval will be:

[tex]w_s = ( B_x^2 + P_x^2)^{\frac{1}{2}[/tex]

[tex]w_s = (0.18^2 + 0.2^2)^{\frac{1}{2}[/tex]

[tex]\mathbf{w_s = 0.2690 \ kg}[/tex]

Sand dunes are constantly moving, with help from the wind. If the wind blows hard enough, it can kick up the sand. This leads to dust storms, which are dangerous for all who live near the dunes. Sand also damages buildings that can be centuries old. For example, sand threatens buildings in Egypt, including the pyramids. The sand can break down the stones that made the pyramids. Though there are easy ways to keep sand dunes from moving, not all are good for the environment. For years, oil has been used to stop sand dunes from moving. People drench the sand dunes with oil, and the sand no longer is picked up by the wind. This is not good for the animals living in and around the dunes. It also wastes an important resource. One way of safely keeping the dunes from moving as quickly is to plant trees and other plants along them. These plants keep the dunes from moving when placed at the bottom of the dunes. The dunes stay in place and keep the animals living in the dunes safe. Scientists are also working on the best design possible for sand fences. These would keep the dunes in place and let the animals continue to live there.4Paragraph 2 uses A. cause and effect organization. B. chronological order organization.
