For each of the following, determine the constant c so that f(x) satisfies the conditions of being a pmf for a random variable X(a) f(x)=xc, x=1,2,3,4. (b) f(x)=cx, x=1,2,3,. ,10. (c) f(x)=c(14)x, x=1,2,3,. (d) f(x)=c(x+1)2, x=0,1,2,3. (e) f(x)=xc, x=1,2,3,. ,n. (f) f(x)=c(x+1)(x+2), x=0,1,2,3,
The constant c that satisfies the condition of probability mass function of the random variable are 1/55, 1/30, 1/56
What is the constant that satisfies the variable
(a) For f(x) to be a probability mass function, it must satisfy the following conditions:
1. f(x) ≥ 0 for all x
2. Σf(x) = 1, where the sum is taken over all possible values of X
Here, x can take values 1, 2, 3, 4
So, Σf(x) = f(1) + f(2) + f(3) + f(4) = c + 4c + 9c + 16c = 30c
For Σf(x) = 1, we need 30c = 1. So, c = 1/30.
(b) Here, x can take values 1, 2, 3,...,10
For Σf(x) = 1, we need c(1+2+3+...+10) = c(55) = 1. So, c = 1/55.
(c) Here, x can take values 1, 2, 3,...
For Σf(x) = 1, we need c(14+142+143+...) = c(14)(1+2+3+...) = c(14)∞ = 1. So, c = 1/(14∞).
(d) Here, x can take values 0, 1, 2, 3
For Σf(x) = 1, we need c(12+22+32+42) = c(1+4+9+16) = c(30) = 1. So, c = 1/30.
(e) Here, x can take values 1, 2, 3,...,n
For Σf(x) = 1, we need c(1+2+3+...+n) = c(n(n+1)/2) = 1. So, c = 2/(n(n+1)).
(f) Here, x can take values 0, 1, 2, 3
For Σf(x) = 1, we need c(12×3+22×4+32×5+42×6) = c(56) = 1. So, c = 1/56.

How many pounds in 73.5 kg?
There are 2.20462 pounds in one kilogram.
Therefore, to convert 73.5 kilograms to pounds, you would multiply 73.5 by 2.20462.
The calculation is as follows:
73.5 kg * 2.20462 pounds/kg = 162.04101 pounds
So, there are approximately 162.04101 pounds in 73.5 kilograms.

Step-by-step explanation:
what is the value of 130 kph in mph
To convert kilometers per hour (kph) to miles per hour (mph), we use the following formula: mph = kph x 0.621371. This is because there are 0.621371 miles in a kilometer.
To calculate the value of 130 kph in mph, we can simply plug the value into the formula: mph = 130 x 0.621371 = 80.78 mph. Therefore, the value of 130 kph in mph is 80.78 mph. To further understand how this conversion works, we can break down the calculation into its basic components. First, we divide 130 by 1. That gives us 130. Then, we multiply 130 by 0.621371, which gives us the result of 80.78. Therefore, the value of 130 kph in mph is 80.78 mph. The above formula and calculation can be used to convert any value from kph to mph. All we need to do is plug the kph value into the formula and we will get the equivalent mph value. It is important to note that the conversion from kph to mph is not exact, as there are slight variations in the exact value of a kilometer. However, this formula provides a good approximation and is accurate enough for most purposes.

What is the value of 20 in asl
To calculate the mathematical value of 20, you would use the : 20 x 1 = 20. This means that 20 multiplied by 1 is equal to 20. Therefore, the value of 20 in ASL is equal to 20.
ASL stands for American Sign Language. It is the visual language used by the deaf and hard of hearing communities to communicate. In ASL, the sign for the number 20 is done by holding up both hands with the palms facing out and fingers spread apart. The hands are then moved together in a circular motion with the fingers crossed at the end. This sign is also used to represent the mathematical concept of multiplication. To express the value of 20 in ASL, you would sign the number 20 by making the above mentioned sign, and then sign the word "equals". To calculate the mathematical value of 20, you would use the formula: 20 x 1 = 20. This means that 20 multiplied by 1 is equal to 20. Therefore, the value of 20 in ASL is equal to 20.

the ________ is the positive square root of the sample variance.
The standard deviation is the positive square root of the sample variance.
Describe Standard Deviation?Standard deviation is a measure of the spread or dispersion of a set of data from its mean (average) value. It tells us how much the individual values in a dataset deviate from the average value. In other words, it indicates the extent to which the data points are spread out or clustered around the mean.
The formula for standard deviation is the square root of the variance, which is calculated by finding the average of the squared differences between each data point and the mean. The standard deviation is expressed in the same units as the original data and is denoted by the symbol "σ" for the population standard deviation or "s" for the sample standard deviation.
A small standard deviation indicates that the data points are clustered around the mean, while a large standard deviation indicates that the data points are spread out over a wider range. The standard deviation can be used to determine the range of values within which the majority of the data points lie. For example, if the standard deviation is 2, then about 68% of the data points will be within 2 standard deviations of the mean.

how much 44 f to c ?
44 °F was found out to be equivalent to approximately 6.67 °C using conversion formula of Fahrenheit to Celsius.
To convert a temperature from Fahrenheit to Celsius, you can use the following formula:
°C = (°F - 32) x 5/9
where °C is the temperature in Celsius, and °F is the temperature in Fahrenheit.
Using this formula, we can convert 44 °F to Celsius as follows:
°C = (44 - 32) x 5/9
= 12 x 5/9
= 6.67 °C (rounded to two decimal places)
Therefore, 44 °F is equivalent to approximately 6.67 °C.
On the Fahrenheit scale, water freezes at 32 degrees Fahrenheit (°F) and boils at 212 °F, at standard atmospheric pressure.
On the Celsius scale, the freezing point of water is defined as 0 degrees Celsius (°C), and the boiling point of water is defined as 100 °C, at standard atmospheric pressure.

What are the 4 levels of measurement statistics?
The four levels of measurement in statistics are nominal, ordinal, interval, and ratio. They differ in terms of the properties of the data and the types of statistical analyses that can be performed on the data.
Nominal level involves data that can be placed into categories or groups with no inherent order or ranking. Examples of nominal data include gender, race, and occupation.
Ordinal level involves data that can be ranked or ordered, but the differences between the data points are not necessarily equal. Examples of ordinal data include educational levels (e.g., high school, college, graduate), or rankings of movies on a scale of 1-5.
Interval level involves data where the differences between the data points are equal, but there is no true zero point. Examples of interval data include temperature (measured in Celsius or Fahrenheit) and calendar years.

No, milliliters (mL) and centiliters (cl) are not the same units of measurement. They are both units of volume, but with different scales.
Is a ml the same as a cl?
A milliliter (mL) is a unit of volume in the metric system, equal to one-thousandth of a liter (1 mL = 0.001 L). Milliliters are commonly used to measure the volume of liquids, such as medicine or cooking ingredients.
A centiliter (cl) is also a unit of volume, and it is equal to one hundredth of a liter (1 cl = 0.01 L). Centiliters are less commonly used than milliliters and are generally used in the same contexts where milliliters are used.
In conclusion, mL and cl are different units of volume and cannot be used interchangeably. Milliliters are smaller units than centiliters, so when converting between the two, a conversion factor of 10 must be used. For example, 1 cl = 10 mL.

What is a cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.
Given are cylinders, we need to find the surface area of them,
The surface area of a cylinder = 2πr(h+r), where r and h are radius and height of the cylinder,
1) Height = 2 in and radius = 3 in
Surface area = 2·3.14·3·(3+2) = 94.5 in²
2) Height = 5 in and radius = 3 in
Surface area = 2·3.14·3(5+3) = 150.72 in²
3) Height = 6 in and radius = 2 in
Surface area = 2·3.14·2(6+2) = 100.48 in²
4) Height = 4 in and radius = 4 in
Surface area = 2·3.14·4(4+4) = 200.96 in²
5) Height = 4 in and radius = 4 in
Surface area = 2·3.14·5(5+5) = 314 in²

Answer:
Let's say the number of sweets that Amol has is A.
According to the problem, the number of sweets that Gemma has is 6 times the number of sweets that Amol has. Therefore, Gemma has 6A sweets.
The number of sweets that Harry has is half the number of sweets that Gemma has. Therefore, Harry has 1/2 * 6A = 3A sweets.
So the ratio of the number of sweets that Amol, Gemma, and Harry have respectively is:
A : 6A : 3A
Simplifying this ratio by dividing each term by A, we get:
1 : 6 : 3
Therefore, the ratio of the number of sweets that Amol has to the number of sweets that Gemma has to the number of sweets that Harry has is 1:6:3
