Two groups separately performed an experiment by tossing a coin in the air. Group A performed 50 trials and group B performed 100 trials. Each group recorded the results in the table below:Group Heads Tails
A 30 20
B 52 48

What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails?

Answers

Answer 1

Answer: Theoretical probability;
Head = 1/2 or 50%
Tail = 1/2 or 50%

Group Heads Tails Total
A 30 20 50
B 52 48 100

Experimental probability:
Group A:
Heads : 30/50 = 60%
Tails: 20/50 = 40%

Group B:
Head: 52/100 = 52%
Tails: 48/100 = 48%

Experimental probabilities of Group B is closer to the theoretical probabilities.

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A. B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B. C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B. D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.

i have a field 60m long and 110 wide going to be paved i ordered 660000000cm cubed of cement how thick must the cement be to cover field

Answers

First find the area of the field
A=WL
A=(110m)(60m)
A=6,600m^2
Now turn the cm into m
becouse 100cm^3=1m^3
660,000,000cm^3=6,600,000m^3
Now find out how many times you can cover the filled
6,600,000m^3/6,600m^2=100m
So it will be 100m thick.
P.S. I'm assuming you meant you jest forgot the m for 110m.

5.Twenty-four dogs are in a kennel. Twelve of the dogs are black, six of the dogs haveshort tails, and fifteen of the dogs have long hair. There is only one dog that is black with
a short tail and long hair. Two of the dogs are black with short tails and do not have long
hair. Two of the dogs have short tails and long hair but are not black. 6 dogs are only
black. How many dogs are black with long hair but do not have short tails. How many
have only Long hair?

Answers

Answer:

Step-by-step explanation: yes

Final answer:

There are 3 black dogs with long hair but do not have short tails and 12 dogs that have only long hair.

Explanation:

The problem at hand relates to the field of set theory and involves operations such as counting and deduction. The first step is to organize the data into different categories of dogs: black dogs, dogs with short tails, and dogs with long hair. Thereafter, we combine the categories based on the additional information provided.

Firstly, there 12 black dogs. Of these, 1 dog has a short tail and long hair, 2 dogs have short tails and no long hair, and 6 dogs are only black. This sums up to 9 dogs. Thus, there are 12-9 = 3 black dogs with long hair but do not have short tails.

Secondly, 15 dogs have long hair. Among these, 1 dog is black with a short tail, and 2 dogs have short tails but are not black. This sums up to 3 dogs, leaving 15-3= 12 dogs with only long hair.

What sort of information can you get from conditional frequencies that you couldn't get by just looking at the relative frequencies?

Answers

Answer:

Conditional frequencies offer more specific information to analyse certain data set.

Step-by-step explanation:

A conditional frequency is a type of relative frequency which involves a condition to be defined.

For example, the conditional frequency of having a house given that the person is female. Notice that this example shows the condition "being female", so the conditional frequency would be all females who own a house.

On the other hand, the relative frequency is just a ratio between the frequency of the data and the total number of data. It's doesn't includes a condition to be defined, that's the difference.

Therefore, conditional frequencies offer more specific information to analyse certain data set.

A migrating bird flies 494 miles in 13 hours. how many miles does it fly in 5 hours

Answers

It is easier to solve problems like these by first taking the unit rate. In this case, we look for how many miles can the bird fly per hour. This is done by dividing the total distance by the total time.

Rate = 494 miles / 13 hours
Rate = 38 miles / hour

Multiplying this by 5 hours:
38 miles / hour * (5 hours) = 190

Therefore, the migrating bird flies 190 miles in 5 hours.
