The probability that at most 24 heads occur is; 24/25.
What do we mean by probability?Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true. The probability of all the events occurring need to be 1.
We have been given that a fair coin is tossed 25 times.
So, We need to find the probability:
Favourable outcomes = 24
Total outcomes = 25
The formula of probability = Favourable outcomes/Total outcomes
⇒ 24 /25
Therefore, the probability that at most 24 heads occur is; 24/25.

The probability of getting at most 24 heads in 25 tosses of a fair coin is approximately 99.999997%
The probability of getting at most 24 heads when a fair coin is tossed 25 times is essentially 100%, because the only other possible outcome is getting exactly 25 heads, which has a very small probability. Since each toss of a fair coin has only two possible outcomes (either head or tail), and each toss is independent, we can use the binomial distribution to find the probability of a certain number of heads occurring.
To calculate the probability of getting exactly 25 heads in 25 tosses, we use the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
Where:
n is the number of trials (tosses), so n=25,
k is the number of successes (heads) we're calculating the probability for, so k=25,
p is the probability of success on any given trial, which is 0.5 for a fair coin.
Substitute these values into the formula, we get:
P(X = 25) = (25 choose 25) * 0.5^25 * (1-0.5)^(25-25)
This equates to:
P(X = 25) = 1 * 0.5^25 * 1 = 1/33,554,432 ≈ 0.00000003 or 0.000003%.
Therefore, the probability of getting at most 24 heads is 1 - P(X = 25) which is approximately 0.99999997 or 99.999997%.

Atrap and Bracken are two rival insurance companies. Atrap and Bracken have premiums of $150 and $100 and deductibles of $2,500 and $3,500 respectively. The average expense of surgery is $25,000. If after 5 years, 25 of the 1,000 people registered with Bracken have gone through surgery, where does Bracken stand in terms of gains or losses?
Answer:
Bracken has incurred a loss of $37,500
Step-by-step explanation:
People who have registered with Bracken insurance company pays premium of $100. 1,000 people in total have registered with Bracken. In 5 years Bracken would have earned an income of $500,000 [tex]\left ( $100\times1,000\times5)\right[/tex].
25 among the 1,000 registered have undergone surgery. Average surgery expense is $25,000. $3,500 is deductible. So Bracken's total expense per client is $21,500 (25,000 - 3,500). For 25 patients, it will be $537,500 [tex]($21,500\times25)[/tex].
Since expenses of $537,500 is more than income of $500,000, Bracken incurs a loss of $37,500 (500,000 - 537,500) over 5 years.
Therefore, Bracken's loss over 5 years is $37,500
The American flag is customarily made with its width and length in the ratio of 10 to 19. Which of the following dimensions is in the correct ratio for the flag?
Final answer:
The given dimensions do not match the American flag's customary ratio of 10 to 19. To find the correct dimensions, the numbers must divide to equal approximately 0.5263. None of the provided options are correct.
Explanation:
The American flag is customarily made with its width and length in the ratio of 10 to 19. To ensure the dimensions are correct, we must find a pair of numbers that, when divided, are in the same proportion as 10/19 (approximately 0.5263). Looking at the listed dimensions:
51 H (Height is not a width or length measurement, so we cannot confirm the ratio)
53 x 38 (53/38 = 1.3947 which is not equal to 10/19)
55 x 0.025 (55/0.025 = 2200 which is not equal to 10/19)
57 x (2.93, 3.59) (This does not provide a pair of length and width measurements)
59 (This is not a dimension)
Since none of the provided options has numbers that mirror the 10 to 19 ratio of the flag, none of these dimensions would be correct for an American flag. If we want to find dimensions that are proportional, we have to look for any two numbers that, when divided, equal approximately 0.5263. Hence, an example of a correct dimension following the flag's ratio would be 10 inches by 19 inches or any multiple thereof.
In the linear equation y = 2x + 1, if x increases by 4 points, how much will y increase?
If [tex]\(x\)[/tex] increases by 4 points, [tex]\(y\)[/tex] will increase by 8 units.
In the linear equation [tex]\(y = 2x + 1\)[/tex], the coefficient of [tex]\(x\)[/tex] is 2. This means that the slope of the line is 2, and for every one unit increase in [tex]\(x\), \(y\)[/tex] will increase by 2 units.
Given that [tex]\(x\)[/tex] increases by 4 points, the corresponding increase in [tex]\(y\)[/tex] can be found by multiplying the change in [tex]\(x\)[/tex] by the slope:
[tex]\[\Delta y = \text{Slope} \times \Delta x\][/tex]
[tex]\[ \Delta y = 2 \times 4 = 8\][/tex]
Therefore, if [tex]\(x\)[/tex] increases by 4 points, [tex]\(y\)[/tex] will increase by 8 units.
Example:
Let's use the given linear equation [tex]\(y = 2x + 1\)[/tex] and demonstrate how an increase in [tex]\(x\)[/tex] by 4 points results in an increase in [tex]\(y\)[/tex] by 8 units.
Given Linear Equation:
[tex]\[y = 2x + 1\][/tex]
Let's consider an initial point on the line where [tex]\(x = 3\)[/tex]. Find the corresponding [tex]\(y\)[/tex]:
[tex]\[y = 2(3) + 1 = 7\][/tex]
So, when [tex]\(x = 3\), \(y = 7\)[/tex].
Now, if [tex]\(x\)[/tex] increases by 4 points, new [tex]\(x\)[/tex] value will be [tex]\(3 + 4 = 7\)[/tex].
Using the same linear equation to find the new [tex]\(y\)[/tex]:
[tex]\[y_{\text{new}} = 2(7) + 1 = 15\][/tex]
Now, calculate the increase in [tex]\(y\)[/tex]:
[tex]\[\Delta y = y_{\text{new}} - y_{\text{initial}} = 15 - 7 = 8\][/tex]
So, in this example, when [tex]\(x\)[/tex] increases by 4 points (from 3 to 7), [tex]\(y\)[/tex] increases by 8 units (from 7 to 15), confirming that the increase in [tex]\(y\)[/tex] is proportional to the increase in [tex]\(x\)[/tex] with a slope of 2.

Sergio runs 2 1/4 miles in 30 minutes. Write the ratio in fractional form and determine Sergio's speed in miles per hour.
Sergio runs at a speed of 4.5 miles per hour. The ratio of his running distance to time is 9/2.
Explanation:To determine Sergio's speed in miles per hour (mph), we use the equation: speed = distance/time. Sergio runs 2 1/4 miles in 30 minutes. First, we need to convert the fractional distance to a decimal and the time to hours. 2 1/4 miles is equal to 2.25 miles and 30 minutes is equal to 0.5 hours.
Substitute these values into the equation:
speed = 2.25 miles/0.5 hour = 4.5 mph.
Therefore, Sergio's running speed is 4.5 miles per hour. The ratio of distance to time in fractional form would be 9/2.
