The statistical measures for the 10-day vacation are given as follows:
a) Mean: $2470.
b) Standard deviation: $189.74.
c) Variance: $²36,001.
What is the mean for the 10-day distribution?To find the mean for n days, we take the mean amount in a single day and multiply by n.
Hence:
247 x 10 = $2470.
What is the standard deviation for the 10-day distribution?To find the standard deviation for n days, we take the standard deviation for a single day and multiply by the square root n.
Hence:
60 x sqrt(10) = $189.74.
What is the variance for the 10-day distribution?The variance is the square of the standard deviation, hence:
($189.74) = $²36,001.

Answer if you know your right, bur don't answer just for the points
Answer:
42% is less than 5/8
Step-by-step explanation:
If 42% is converted to a fraction, it comes out to 21/50, which is smaller than 5/8. You could also convert 5/8 into a percentage, which comes out to 62.5%. :)
Answer:
42% < 5/8
Step-by-step explanation:
We're going to change 5/8 to a percent. All you have to do is 5/8, which is 0.625. If you want to convert a decimal to a fraction, you move the decimal 2 places to the right, which is 62.5. Therefore, 42% is less, or < than 5/8.

the expression sinx + cotx cosx can be simplified to what
after simplifying the expression sinx + cotx cosx, we get the result as cosec x.
We are given the expression:
sinx + cotx cosx
We need to simplify the expression.
We know that cot x can also be written as
cot x = cos x / sin x
Substituting it in the expression, we get that:
= sin x + ( cos x / sin x ) cos x
opening the brackets, we get that:
= sin x + cos² x / sin x
= (sin² x + cos² x ) / sin x
Using the trigonometric identity that sin² x + cos² x = 1, we get that:
= 1 / sin x
= cosec x
Therefore after simplifying the expression sinx + cotx cosx, we get the result as cosec x.

The cost of a ticket to the circus is $14.00 for children and $38.00 for adults. On a certain day, attendance at the circus was 700 and the total gate revenue was $19,400. How many children and how many adults bought tickets?
Answer:
300 children and 400 adults
Step-by-step explanation:
14(x) + 38(700-x) = 19,400
14x + 26,600 - 38x = 19,400
14x - 38x = -7,200
-24x = -7,200
24x = 7,200
x = 300
x = childrens
700 - x = adults
300 = children

A dish containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16 How many times larger is the diameter of the dish than the diameter of the bacterium
For a dish that is containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16, the number of times that the diameter would be larger is 10¹² times.
How to solve for the diameterWe have the diameter of the dish to be 0.0001
This is the same as 10⁻⁴
The bacterium has the diameter at 10^-16
The difference between the diameter of the dish than the bacterium would be solved by
1 x 10⁻⁴ / 10^-16
= 10¹²
Hence we would have to say that for a dish that is containing bacteria has a diameter of 0.0001 kilometer. The diameter of a bacterium is 10^-16, the number of times that the diameter would be larger is 10¹² times.

Globalization
?
A. More unequal distribution of natural resources
B. Improved incomes for poor people in all countries
C. Decreased competition for small businesses
OD. Decreased demand for natural resources
The phrase that best relates to the term "Globalization" is "Improved incomes for poor people in all countries".
As per the question statement, we are provided with the term of "Globalization" and we are required to match it with the best possible phrase from the four options provided.
Option (A) is "More unequal distribution of natural resources" which is incorrect because unequal distribution does not depend on globalization but on the size of the company and their effects on the environment.
Option (C) is "Decreased competition for small businesses" which is incorrect because this will increase the competition for small business.
Option (D) is "Decreased demand for natural resources" which is incorrect, since globalization speeds up the exchange of capital-labor production which requires more natural resources rather than their decrease.
Option (B) is "Improved incomes for poor people in all countries" which is the correct match, because globalization's main character is economic growth which directly affects the totally population of a country including the poor as the country becomes open to trade and then tends to work faster than the time when it was not open to trade, and this creates job opportunity for the people and helps in increasing the living standard of the people.
Hence, the best possible match to the term "Globalization" is "Improved incomes for poor people in all countries".

5. If that same manufacturer miscalculates the demand of the market and manufactures 5,000 dozen of those sweaters, but only sells 3,000 dozen, what is the total profit from the sweaters? (Show your calculations.) $ profit.
If a manufacturer manufactures 5,000 dozen of sweaters, and sells 3,000 dozen of them only, then the total profit he/she earns from the these sweaters is [1000(3x - 5y)], assuming that the cost of manufacturing one sweater is "x" and the selling price of that sweater is "y".
As per the question statement, a manufacturer miscalculates the demand of the market and manufactures 5,000 sweaters, but sold only 3000 of them.
We are required to calculate the total profit earned by the manufacturer from the sale of the sweaters.
Since, no data about the manufacturing cost of the sweaters and their selling price is provided in the question statement, let us assume that the cost of manufacturing one sweater is "x" and the selling price of that sweater is "y". Solving with these variables will give us a generalized answer which we can use for any value.
Now, Since assumed that, manufacturing cost of one sweater is "x", then, manufacturing cost of 5000 sweaters will be [tex](5000*x)=5000x[/tex].
Similarly assumed that, selling cost of one sweater is "y", and then, selling cost of 3000 sweater will be [tex][(3000*y)=3000y][/tex].
Now, we know that,
[Profit = (Total Selling Cosy) - (Total Manufacturing Cost)],
Therefore, in this case, total profit from the sale of 3000 sweaters
[tex]=(3000y-5000x)\\=1000(3y-5x)[/tex].
Now, on using real integers or numbers in place of "x" and "y", if the value of Profit comes negative, it will mean, that for those values of "x" and "y", the manufacturer makes loss, not profit.
Profit: On sale of any goods, a person makes profit if he/she can sell the goods for a higher value than what they had bought for, or what they had manufactured at and is thus, calculated as the difference of total selling price of the goods and the manufacturing cost or buying price of them.Loss: This is the exact opposite of profit and is calculated as the difference of manufacturing cost or buying price of the goods and their selling price.To learn more about Profit and Loss, click on the link below.

What score must the student earn on the next exam to have an average of at least 90?
We know that the scores on the first 3 exams are 85, 87, and 91.
If the score in the fourth exam is x, then the average of the 4 exams will be:
(85 + 87 + 91 + x)/4
If we want to have an average of at least 90, then we need to solve:
(85 + 87 + 91 + x)/4 = 90
Solving that for x we will get:
(263 + x) = 90*4

Fractions represent parts of a whole or collection of objects. In the above question the value of x is equals to 9
What is a fraction?Fractions represent parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called numerator. It tells how many equal parts of whole or collection are taken. The number below line is called denominator. It shows total number of equal parts the whole is divided into or the total number of the same objects in a collection.
When whole is divided into equal parts, the number of parts we take makes up a fraction.
In the mathematics, there are three major types of fractions. They are the proper fractions, improper fractions and mixed fractions. Fractions are those terms which have the numerator and denominator. Fractions are the terms used to determine parts of a whole object.
