The price of carrots per ounce is $0.24 .

Ounce is an unit of mass in the Imperial System. It is widely used throughout the world and is one of the oldest units of measurement to still exist. The unit ounce is derived from uncia, a unit of measurement in roman times.

The ounce(abbreviated oz) is equal to approximately 28.35 grams and 16 ounces make up a pound.

Now it is given that a 2-pound bag of carrots cost $7.68 .

Therefore price per pound of carrots=$7.68÷2

Price per pound=$ 3.84 .

Now we know that 16 ounces make up a pound.

Price of carrots per ounce=  $3.84 ÷16

Price per ounce=  $ 0.24

Therefore the price of carrots per ounce is $0.24

The area of the region enclosed by the curves y = 7sin x and y = sin(7x) , 0 < x < π is 13.7 square units.

Given the equation of the curves:

y = 7sin x and y = sin(7x)

Now, we have to find the area between the curves .

Area between y = 7sin x and y = sin(7x) ,

   A = ∫[7sin(x) - sin(7x)]dx

⇒ A = [-7cos(x) + 1/7 cos(7x)]

⇒ A = [-7cos + 1/7 cos(7)] - [-7cos(0) + 1/7 cos(0)]

Since cos(π) = -1  ;  cos(7) = -1  ; cos(0) = 1

⇒A = [-7(-1) + 1/7 * (-1)] - [-7 * 1 + 1/7 * 1]

⇒A = 7- 1/7 + 7 - 1/7

⇒A = 14 - 2/7

⇒A = 96/7

⇒A = 13.7 units

2√10/3 is irrational number

The term "rational number" refers to any number that can be stated as a fraction, as well as a positive, negative, or zero. If q is not equal to zero, it can be expressed as p/q.

The word "rational" is derived from the word "ratio," which is a fraction and really refers to a comparison of two or more values or integer numbers. It is the ratio of two integers, to put it simply.

Consider the rational integer 3/2. It denotes that the integer 3 is divided by the number 2.

Irrational numbers are those that are not rational in nature. Let's explain; irrational numbers can be expressed as decimals but not as fractions, hence they cannot be expressed as the ratio of two integers.

After the decimal point, irrational numbers have an infinite amount of non-repeating digits. Here's an illustration of an irrational number:

For instance, 8 = 2.828

MULTIPLYING THE TWO NUMBERS,

2/√18 x 2√5

= 2 /3√2 x 2√5

= 4√5/3√2

= 2√2 x √5 /3

= 2√10/3

rational number multiplied by an irrational number is always a irrational number.

Since √10 is a irrational number, therefore, 2√10/3 is irrational number.

- ( 7 x - 3 y ) + 2 ( 3/4 x + 1/2 y)

First we will multiply 2 and open the brackets.

So, we get that:

- 7 x + 3 y + 3/2 x + y

Combining the like terms, we get that:

= ( - 14 + 3 ) x / 2 + 3 y + y

Simplifying and solving the expression to obtain the result, we get that:

= - 11 / 2 x + 4 y.

Mean and standard deviation is more affected by extreme observations.

Mean is the summation of all the values divided by the total number of values. It is also called as average. Median is the middle value.Standard deviation is the dispersion of a dataset relative to its mean. In case of extreme items arithmetic mean is affected very much. For this reason, it no longer remains representative of the distribution. As standard deviation is the positive square root of the arithmetic mean of the square of deviations of all given values, it is also affected by extreme items. As median is a partition value, it is not affected by extreme items.

Expressing x in terms of 0 and y gives x = 0 + (32/23)y

Given the expression 23x-32y = 0 with number bases x and y.

This equation actually expresses 0 in terms of x and y as 0 is isolated to one side of the equality.

We have to express x in the same equation in terms of 0 and y.

So we need to isolate x to one side of the equality.

23x-32y = 0

⇒23x = 0 +32y

Dividing throughout by 23 gives,

Step-by-step explanation:

the absolute deviation for the man is 3 years more than the one for the woman.

We know that the absolute value function:

m(x) = |x - 44|

Represents the absolute deviation of man's age, in years.

This means that the average age of a man in that city is 44 years old, so if a man has 64 years, then the absolute deviation is given by:

m(64) = |64 - 44| = 20

The absolute deviation for a man of 64 years old living in this city is 20 years.

Similar for the case of women, the equation here is:

w(x) = |x - 47|

If a woman has 64 years old, then the absolute deviation is:

w(64) = |64 - 47| = 17

The absolute deviation is 17 years.

We can see that the absolute deviation for the man is 3 years more than the one for the woman.

It was mostly during C . Dry season

The “Cricket Season” is the period of days where cricket is played in a country when the pitches get dry and also this is the period where the domestic matches begin.

And this season varies with countries, in India it starts with the Ranjit Trophy, Sheffield Shield for Australia etc.

Cricket seasons are the times of the year when cricket is played. Because top-class cricket is almost always played outdoors, on uncovered pitches, and rain prevents play, the seasons in each country are geared to coincide with the driest months of the year

    The cricket season starts at the beginning of April and finishes at the end of September. As the time zones move around the planet, the seasons will differ in other countries.

In the UK,

professional games have occasionally taken place at the end of March but the season will normally begin at the start of April.

In India

The cricket season in India will usually begin in mid-September. Often, there are senior women’s games starting things off before men’s tournaments commence in October.

In Australia

Cricketers in Australia may start playing in September, especially in the west of the country which gets the warmer weather first.

The the value of constant proportionality k is 3 and the value of y is 42 when the value of x is 14.

Constant proportionality:

Constant proportionality means the ratio of two proportional values at a constant value.

Directly Proportional:

In direct proportion, if one quantity is increased or decreased then the other quantity increases or decreases, respectively.

Given,

Suppose that y is directly proportional to x.

And y = kx.

Here we need to find the value of k when the value of x = 10 and the value of y = 30.

And we also need to find the value of y when the value of x = 14.

First, we have to find the value of k by apply the given value of the equation,

=> 30 = k x 10

=> 30 /10 = k

=> k = 3

Now the value of y when the value of x = 14 and the value of k = 3,

Then

=> y = 3 x 14

=> y = 42.

Therefore, the value of constant proportionality k is 3 and the value of y is 42 when the value of x is 14.

The  entire area under the standard normal distribution curve is always positive even if the z value is negative.

The normal distribution, it's useful to think of the standard deviation as being steps away from the mean. One step to the right or one step to the left is considered one standard deviation away from the mean. Two steps to the left or two steps to the right are considered two standard deviations away from the mean. Likewise, three steps to the left or three steps to the right are considered three standard deviations from the mean.

The probability of the outcome of an experiment is never negative, although a quasi probability distribution allows a negative probability, or quasi probability for some events. These distributions may apply to unobservable events or conditional probabilities.
