Sandy used a virtual coin toss app to show the results of flipping a coin 100 times, 500 times, and 1,000 times. Explain what most likely happened in Sandy's experiment.

Sandy's experimental probability was closest to the theoretical probability in the experiment with 100 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 500 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.
Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.

Answers

Answer 1

Answer:

Step-by-step explanation:

To determine what most likely happened in Sandy's experiment, we need additional data on the outcomes of the virtual coin tosses in each experiment. Without this data, we cannot directly compare the experimental probability to the theoretical probability.

However, we can make some general observations based on the law of large numbers and the concept of convergence. The law of large numbers states that as the number of trials or experiments increases, the experimental results tend to converge towards the theoretical probabilities. This means that with a larger number of flips, the experimental probability is more likely to be closer to the theoretical probability.

Therefore, based on this principle, it is reasonable to assume that Sandy's experimental probability was likely closest to the theoretical probability in the experiment with 1,000 flips. As the number of flips increases, the chances of the experimental results aligning closely with the theoretical probability increase.

However, it is important to note that without the specific data on the outcomes of each experiment, we cannot definitively determine which experiment had the experimental probability closest to the theoretical probability.

Answer 2
Based on the given information, we can analyze Sandy's experiments with different numbers of coin flips and their relation to the theoretical probability.

1. Sandy's experimental probability was closest to the theoretical probability in the experiment with 100 flips:
In this case, the experimental results of the 100 coin flips were the closest to what would be expected based on the theoretical probability. This suggests that the outcomes of the coin tosses were distributed in a manner that aligned closely with the expected probabilities of getting heads or tails.

2. Sandy's experimental probability was closest to the theoretical probability in the experiment with 500 flips:
Similarly, the experimental results of the 500 coin flips were closest to the expected outcomes based on the theoretical probability. This implies that the larger sample size provided more accurate results, reducing the impact of random fluctuations and yielding a distribution that better matched the theoretical expectations.

3. Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips:
Once again, the experimental results of the 1,000 coin flips were the closest to the expected probabilities based on the theoretical probability. With an even larger sample size, the impact of random variation would be further minimized, resulting in an outcome that more closely matched the theoretical expectations.

4. Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments:
This statement suggests that the experimental results perfectly matched the expected probabilities for all three experiments. However, it is highly unlikely for the experimental results to exactly match the theoretical probabilities due to the inherent randomness in flipping a coin. Therefore, it is less probable for this scenario to be true.

To summarize, the most likely scenario is that Sandy's experimental probability was closest to the theoretical probability in the experiment with the largest number of coin flips (1,000 flips). As the sample size increased, the experimental results became more accurate and aligned more closely with the expected probabilities.

Rewrite the expression c + 0.25c as a single term with a fractional coefficient.
please help (No spam) (No stu-pid answers please)

Answers

Answer:

5c/4

Step-by-step explanation:

c = c × 1

0.25c = 0.25c × 1

c + 0.25c

Take " c " common.

= c × (1 + 0.25)

= c × 1.25

Convert 1.25 into a simpler fraction

1.25

= 125/100

= 5/4

c × 1.25

= c × 5/4

= (c × 5)/4

= 5c/4

The fractional coefficient is (5c/4)

What is a coefficient?

A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term

Given:

[tex]\sf c+0.25c[/tex]

[tex]\sf =(1+0.25)c[/tex]

[tex]\sf =(1.25)(c)[/tex]

[tex]\sf =1.25c[/tex]

[tex]\sf =\dfrac{125}{100}[/tex]

[tex]\sf =\dfrac{5}{4}[/tex]

Amal usually brings lunch to the school in the lunch box shown below. The length, breadth, and height of the box are in the ratio of 2:3:4 and the sum of the cubes of length, breadth, and height of the box equals 33957 cm³.
Find the length of the longest edge of the box.
Find the sum of the length and breadth of the box.

Answers

Answer: length of longest side = 15092 cm

sum of length and breadth = 18856 cm

Step-by-step explanation:

1st question

length : breadth : height

    2     :       3      :      4

2 + 3 + 4 = 9

33957 ÷ 9 = 3773

longest side is the height because it has the biggest number in the ratio

∴ longest side = 4 × 3773 = 15092 cm

2nd question

length : breadth : height

    2     :       3      :      4

2 + 3 + 4 = 9

33957 ÷ 9 = 3773

→ length = 2 × 3773 = 7546 cm

→ breadth = 3 × 3773 = 11319 cm

∴ length + breadth = 7546 + 11319 = 18865 cm

Hope this helps!

The Length of longest edge of the box = 28 cm

The Sum of length and breadth of the box = 35 cm

Steps to calculate the length, breadth and height

Given, ratio(length : breadth : height) = (2:3: 4)

Let length = 2x, breadth = 3x and, height = 4x

Given, the sum of the cubes of length, breadth, and height of the box equals 33957 cm, therefore

[tex](2x)^3[/tex] + [tex](3x)^3[/tex] + [tex](4x)^3[/tex] = 33957

8[tex]x^{3}[/tex] + 27[tex]x^{3}[/tex] + 64[tex]x^{3}[/tex] = 33957

99[tex]x^{3}[/tex] = 33957

[tex]x^{3}[/tex] = 343

[tex]x^3[/tex] = [tex]7^3[/tex]                                                  

x = 7.

Therefore, length    = 2x = 2*7 = 14 cm, breadth = 3x = 3*7 = 21 cm, height   =  4x = 4*7 = 28 cm. Hence, Length of longest side(height) = 28 cm, Sum of length and breadth = 35 cm

Answers

Answer:

Mario

Step-by-step explanation:

Sheila has a 5 dollar allowance and saved for 3 weeks. 3 x 5 = 15 dollars saved total. She spends 9 of the 15. 15 - 9 = 6, so Sheila donated 6 dollars.

Mario has a 4 dollar allowance and saves for 4 week. 4 x 4 is 16 dollars saved. He then spends 8 of them, 16 - 8 = 8 dollars donated.

Gina has a 6 dollar allowance and saves for 4 weeks. 6 x 4 is 24. She then spends 17 dollars. 24 - 17 is 7 dollars donated.

Sheila donates 6 dollars. Mario donates 8 dollars. Gina donates 7 dollars.
Out of the three, Mario has donated the most.

Kelly wants to make a fruit salad made up of bananas, apples, and peaches. She wants to mix one part apples, 2 parts peaches, and 3 parts bananas. Bananas cost $2.00 per pound, apples cost $4.00 per pound, and peaches cost $5.00 per pound. Kelly only has $10.00, and will spend it all on fruit salad. Write an equation and use this equation to determine how many pounds of fruit salad he can make.

Answers

Step-by-step explanation:

If x is the pounds of apples, 2x is pounds of peaches, and 3x is pounds of bananas, then the total cost is:

4(x) + 5(2x) + 2(3x) = 10

4x + 10x + 6x = 10

20x = 10

x = 0.5

Kelly buys 0.5 pounds of apples, 1 pound of peaches, and 1.5 pounds of bananas, for a total of 3 pounds of fruit.

Answers

Question 1)

Volume of Tank A = Sum of volume of its two parts.

So,

Volume of Tank A = 24 + 96 = 120 cubic feet

Question 2)

Volume of Tank B and Tank A is the same. So, Volume of Tank B = 120 cubic feet

One section of Tank B = 45 cubic feet

So, volume of other section of tank B = 120 - 45 = 75 cubic feet

hope this helps sorry

The ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27. Option B is correct.

Ratio of the volume of the smaller tank compared to the volume of the larger tank = Volume of smaller tank/Volume of larger tank.

Volume of cube =

a = length of side of cube.

Length of the side of the smaller tank = 15cm.

Length of the side of the larger tank = 45cm.

Volume of smaller tank = (15)³ = 3375 cm³

Volume of larger tank = (45)³ = 91125 cm³

Ratio of the volume of the smaller tank compared to the volume of the larger tank = 3375/91125 = 1/27.

Therefore the ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27.

Makayla bought stock in a company two years ago that was worth x dollars. During the first year that she owned the stock, it increased by 12%. During the second year the value of the stock decreased by 7%. Write an expression in terms of x that represents the value of the stock after the two years have passed.

Answers

The value of the stock after the first year would be 1.12x because it increased by 12%.

To find the value of the stock after the second year, we need to multiply the first year's value by the percentage change of the second year:

1.12x - (0.07)(1.12x)

Simplifying this expression, we get:

1.12x - 0.0784x

Combining like terms, we get:

1.0416x

Therefore, the expression that represents the value of the stock after the two years have passed is 1.0416x.

jessica paid [ 0.29 / 0.32 / 0.55 ] , [ more/ less ] than amber at lunch

Answers

Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

You deposit $100 in a savings account. The account earns 5% simple interest per year.
A.)What is the interest earned after 8 years?
B.)What is the balance after 8 years?

Answers

Is this what you are looking for?:
A) $40
B) $140

The deposited amount in the bank is $100

The simple interest per year on the account is 5%

Every year the account holder will earn 5% of the deposit

In this case, the account holder will earn 5% of 100$ every year

So in the first year interest earned would be= 100× 5/100

= $5

Interest earned in first year= $5

Since the deposit amount is constant and interest is 5%

Interest earned in 8 years= 5×8

= $40

Interest earned after 8 years = $40

Balance after 8 years would be= Initial balance + Interest earned

= 100+ 40

=140

The balance in the account after 8 years is $140

Find the vertical distance between points X(−2,3) and Y(−2,114) .

Answers

Answer:

111

Step-by-step explanation:

114-3

Answer:

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.

In other words you get the basic idea, you can also just count, but whatever.
