if we repeatedly toss a balanced coin, then, in the long run, it will come up heads about half the time. but what is the probability that such a coin will come up heads exactly half the time in 16 tosses
if we repeatedly toss a balanced coin, then, in the long run, it will come up heads about half the time. but the probability that such a coin will come up heads exactly half the time in 16 tosses is 1 in 65536 (2^16).
This can be calculated using the binomial probability formula which states that the probability of getting a certain number of heads in a certain number of tosses is given by (Number of ways to get the desired number of heads) / (Total number of possible outcomes). In this case, the number of ways to get 8 heads in 16 tosses is equal to 16C8, or 120.
The total number of possible outcomes is equal to 2^16, or 65536. Thus, the probability of getting 8 heads in 16 tosses is 120/65536, which is approximately equal to 1/65536.

What is the distance formula for a triangle?
The distance formula for a triangle is the Pythagorean Theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The distance formula for a triangle is the Pythagorean Theorem, which outlines a relationship between the three sides of a right triangle. Specifically, the theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. To find the distance between two points in a triangle, you must first determine the length of all three sides. Once you know the lengths of all three sides, you can use the Pythagorean Theorem to calculate the distance between the two points. To use the theorem, you must first calculate the square of the hypotenuse. Then, you must square the lengths of the other two sides and add them together. Finally, you can take the square root of the sum of the squares to calculate the distance between the two points.

A survey asks students how many children are in their household. Complete the table to compute the average number of children per household
The average of children per household is approximately 2.1387931034482758.
What is average ?
In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
To compute the average number of children per household, you would add up the total number of children in all the surveyed households and divide that number by the total number of households surveyed. You can use the following formula:
Average = (Sum of (children x frequency)) / (Total number of households surveyed)
Children Frequency Children x Frequency
0 2 0
1 8 8
2 10 20
3 4 12
4 3 12
5 2 10
Sum of (children x frequency) = 8 + 20 + 12 + 12 + 10 = 62
Total number of households surveyed = 2 + 8 + 10 + 4 + 3 + 2 = 29
Average = 62 / 29 = 2.1387931034482758
So the average number of children per household is approximately 2.1387931034482758

a household having 0.5 inch pipe consumed 45 units of water in a month. Calculate the payment of bill including 50% sewage service charge if the payment is made within one month of bill issued.
Rate,
1 unit=1000 liters
minimum consumption=10 units
minimum charge= Rs 100 rs 32 per unit
in first month 3% discount
Answer: In order to calculate the bill for this household, we will need first to determine the total amount of water consumed in liters. Since 1 unit is equal to 1000 liters, we can multiply the number of units (45) by 1000 to find this value. 45 units * 1000 liters/unit = 45,000 liters
Next, we will need to determine the cost of the water consumed. Since the rate is Rs 32 per unit, we can multiply the number of units consumed by the rate to find the cost of the water. 45 units * Rs 32/unit = Rs 1440
Since the household consumed less than 10 units of water, they will be charged the minimum charge of Rs 100.
Now we need to calculate the sewage service charge which is 50% of the bill. So, Rs 1440 * 0.5 = Rs 720
Now we need to add the sewage service charge with the water bill and get the final bill. Rs 1440 + Rs 720 = Rs 2160
Since the payment is made within one month of the bill being issued, there is a 3% discount so that the final bill will be Rs 2160 - (3/100)*Rs 2160 = Rs 2094
So, the payment of the bill including a 50% sewage service charge if the payment is made within one month of the bill being issued would be Rs 2094.

The propagated error in computing the volume of the cube is estimated to be 0.50 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.28 inch2, both rounded to two decimal places.
(a) Volume of the cube
= (17 inches + 0.02 inch)3
= 17.02 inches3
Propagated error
= (17.02 inches3 - 17 inches3)
= 0.02 inch3
(b) Surface area of the cube
= 6(17 inches + 0.02 inch)2
= 617.04 inches2
Propagated error
= (617.04 inches2 - 617 inches2)
= 0.04 inch2
The edge of the cube is measured to be 17 inches, with a possible error of 0.02 inch. By using differentials, the propagated error in computing the volume of the cube is estimated to be 0.02 inch3, and the propagated error in computing the surface area of the cube is estimated to be 0.04 inch2. Both of these errors were rounded to two decimal places, resulting in a propagated error in computing the volume of the cube being 0.50 inch3, and the propagated error in computing the surface area of the cube being 0.28 inch2.

Two boats left the harbour at the same time. One travelled at 10km/h on a bearing N47degreeE. The other traveled at 8km/h on a bearing of N79degreeE. How far apart are the boats after 45min? Round the distance to nearest tenth of a km.
Answer:
4.0 km
Step-by-step explanation:
You want the distance between two boats after 45 minutes if they left at the same time and traveled 10 km/h at N47E, and 8 km/h at N79E.
Law of cosinesThe distances the boats traveled in 3/4 hour can be found by multiplying the speed by the time:
distance = speed · time
distance = {10 km/h, 8 km/h} · (3/4 h) = {7.5 km, 6 km}
The distance between their positions can be found from the law of cosines:
c² = a² +b² -2ab·cos(C)
Here, the angle between the vectors is 79° -47° = 32°, so the distance is given by ...
c² = 7.5² +6² -2·7.5·6·cos(32°) ≈ 15.925671
c ≈ √15.925671 ≈ 3.9907
To the nearest tenth km, the distance between the boats is 4.0 km.

What is the value of x? Enter your answer in the box. x = A triangle with midsegment parallel to the base. the left side is labeled 40 cm below the midsegment and 5 cm above the midsegment. the right side is labeled 2 x + 10 c m below the midsegment and 3 c m above the midsegment.
The value of x is 25 cm, which was calculated by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm). solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.
x = 25 cm
We can calculate the value of x by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm).
Subtracting 5 cm and 3 cm from 40 cm and 2x+10 cm gives us 35 cm and 2x, respectively.
We can then solve for x by subtracting 35 cm from both sides of the equation to get 2x = -35 cm.
Dividing both sides by 2 gives us x = -17.5 cm.
Since x must be a positive value, the correct answer is x = 25 cm.
The value of x is 25 cm, which was calculated by subtracting the total of the two lower measurements (40 cm and 2x+10 cm) from the total of the two upper measurements (5 cm and 3 cm).

The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides. 36
Answer: The measure of an exterior angle of a regular polygon is given by the formula:
(n-2) * 180 / n
Where n is the number of sides of the polygon.
So, if the measure of an exterior angle of a polygon is 36 degrees, we can set up the equation:
(n-2) * 180 / n = 36
To find the measure of an interior angle, we can use the formula:
(n-2) * 180 / n = (n-2) * 180 / n
So, if the measure of an exterior angle is 36, the measure of an interior angle would be:
(n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n = (n-2) * 180 / n
To find the number of sides, we can use the formula:
n = (180 / (180-x))
So, if the measure of an exterior angle is 36, the number of sides would be:
n = (180 / (180-36)) = (180 / 144) = 5
Therefore, a regular polygon with an exterior angle measure of 36 degrees has 5 sides and an interior angle measure of 144 degrees.

Find the ratio x:y
Give your answer in its simplest form.
Answer: [tex]3:2[/tex]
Step-by-step explanation:
Using the zero-product property, we know that [tex]2x-3y=0[/tex] or [tex]x+5y=0[/tex]. We can rearrange these cases to yield [tex]x=\frac{3}{2}y[/tex] and [tex]x=-5y[/tex].
However, since [tex]x[/tex] and [tex]y[/tex] have the same sign, we neglect the case [tex]x=-5y[/tex]. This means [tex]x=\frac{3}{2}y[/tex].
[tex]x=\frac{3}{2}y \implies \frac{x}{y}=\frac{3}{2} \implies x:y=3:2[/tex]
Answer: We can use the distributive property to expand the left side of the equation:
2xx + 2x5y - 3yx - 3y5y = 0
Then, combine like terms:
2x^2 + 10xy - 3xy - 15y^2 = 0
Now we can add 3xy + 15y^2 on both sides of the equation to get:
2x^2 + 10xy = 0
We know that x and y are positive, so we can divide both sides by 2:
x^2 + 5xy = 0
and since x>0, we can divide both sides by x:
x + 5y = 0
So the ratio x:y = x/(-5y) = -x/5y.
To simplify we can divide x by -x and 5y by 5y and get the final answer as
