No, milliliters (mL) and centiliters (cl) are not the same units of measurement. They are both units of volume, but with different scales.

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.

The standard deviation is the positive square root of the sample variance.

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.

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

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.

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.

The constant c that satisfies the condition of probability mass function of the random variable are 1/55, 1/30, 1/56

(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.

there are 50 adult tickets and 100 student tickets sold

Step-by-step explanation:

Let x = number of adult tickets and y= number of student tickets

We have the following equation

x + y = 150        (1)   =>total number of tickets

7x + 5y = 850   (2)  > total cost of x adult and y student tickets

Multiply (1) x 5:

5x + 5y = 750    (3)

Subtract (2) - (3)

7x + 5y - (5x + 5y) = 850 - 750

7x - 5x + 5y - 5y = 100
2x = 100

x = 50

y = 150 - 50 = 100
