What is the mean of the numbers 25 30 27 23 and 25?
The mean of the given data set is 26.
One of the most significant and often employed metrics of central tendency is the mean. In mathematics, there are various different kinds of means. In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a particular set of observations.
To put it another way, calculating the mean of a data set only requires adding up all the values and dividing the result by the total number of values.
The mean formula in statistics for a set is defined as the sum of the observations divided by the total number of observations.
Mean = 25+30+27+23+25/5
Mean = 130/5 = 26
Thus, the mean of the given data set is 26.

At a football game, a vender sold a combined total of 191 sodas and hot dogs. The number of sodas sold was 43 more
than the number of hot dogs sold. Find the number of sodas sold and the number of hot dogs sold.
Number of sodas sold:
Answer:
There were 74 hot dogs and 117 sodas sold.
Step-by-step explanation:
The following equation describes the conditions of the question:
[tex]191=x+(x+43)\\191=2x+43\\[/tex]
where x is the number of hot dogs sold.
Solve for x:
[tex]191=2x+43\\(191)-43=(2x+43)-43\\148=2x\\\frac{148}{2}=\frac{2x}{2}\\74=x[/tex]
There were 74 hot dogs sold and (74+43) or 117 sodas sold.

Therefore , the factors of the given equation are (x + 4), (x - 5) and (x + 1)
What is equation?The equal sign is used between numerical or changeable expressions to create an equation, such as 3x+5=11.
A number that can be entered as the variable's replacement in an equation serves as the solution.
Here,
The first term, x2, has a coefficient of 1 and is the starting term.
The coefficient of the middle word, +5x, is 5, thus
"The constant," the final word, is +4.
Step 1: Multiply the first term's coefficient by the formula 1 + 4 = 4.
Step 2 is to identify two factors of 4 whose sum equals the middle term's coefficient, which is 5.
-4 + -1 = -5
-2 + -2 = -4
-1 + -4 = -5
4 + 1 = 5
Step 3: Rewrite the polynomial by separating the middle term into the two parts 1 and 4 x2 + 1x + 4x + 4 discovered in Step 2 above.

The altitude of an isosceles triangle is sqrt (a^2 - b^2 / 4).
In the triangle ABC, sides AB and AC are equal (say a) and side BC = b. Let us consider the triangle ADC which is the right triangle in the isosceles triangle ABC, and by Pythagoras' theorem,
we get that the altitude AD of the isosceles triangle can be obtained:
AD ^ 2 = AC ^ 2 - (BC / 2) ^2

A women put $600 into a savings account for one year. The rate of interest on the account was 6%. How much was the interest for the year in dollars and cents.
Answer:
The interest is $36 or $3600 cent
Step-by-step explanation:
6% = 0.06
Take 600 times 0.06 = $36
$1 = 100 cent
$36 = $3600 cent
So, the interest is $36 or $3600 cent
Answer:
Let A = total amount principal + interest
P = principal amount , $600
R = interest rate, 0.06
T = time , 1
A = P(1 + r)^t
A = 600(1 + 0.06) we dont have to put 1 as exponent
A = 600(1.06)
A = 636
Interest = A - P
Interest = 636 - 600
Interest = 36

The volumes of the cone and cylinder are 1256m³ and 5652m³
What is the formula volume of a cone and a cylinder?For a cylinder, the formula is πr²h. A cone is ⅓ the volume of a cylinder, or 1⁄3πr²h.
Given here dimensions as the height of the cone = 12m and radius of its circular base = 10m and the height of the cylinder = 18m
thus Volume of the cone = 1⁄3πr²h
= 1/3×3.14×100×12
= 1256m³
And the volume of the cylinder = πr²h
= 3.14×100×18
= 5652m³
Therefore the volumes of the cone and cylinder are 1256m³ and 5652m³

What is the arithmetic mean of the data set 11 12 13 14 15 16 17 18 19 and 20?
The arithmetic mean of the set of numbers 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 is 15.5. This is the average value of the set, and it is affected by all the values in the set.
The arithmetic mean, also known as the average, of a set of numbers is found by adding up all the numbers in the set and dividing by the total number of numbers in the set. In this case, the set of numbers is 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20. When we add up all the numbers in the set, we get a total of 155. There are 10 numbers in the set, so the average is 155 / 10 = 15.5.
To find the arithmetic mean, we first need to add up all the numbers in the set. Then, we divide that sum by the total number of numbers in the set. This gives us the average value of the set.
In summary, the arithmetic mean of the set of numbers 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 is 15.5. This is the average value of the set, and it is affected by all the values in the set.
