The population variance of the capacities is 30.76

the capacities (in ampere-hours) of 10 batteries are 140, 136, 150, 144, 148, 152, 138, 141, 143, 151.

The number of observations n = 10

mean = (x₁ + x₂ + x₃.....x₁₀)/10

mean = (140 + 136 + 150 + 144 + 148 + 152 + 138+ 141 + 143 + 151)/10

mean = 1443/10 = 144.3

variance = ∑(x - mean)²/(n - 1)

variance = ((140 - 144.3)² + (136 - 144.3)² + (150 - 144.3)² + (144- 144.3)² + (148 - 144.3)² + (152 - 144.3)² + (138 - 144.3)² + (141-144.3)² + (143 - 144.3)² + (151 - 144.3)²)/(10 - 1)

variance = 276.9/9 = 30.76

Therefore, the population variance of the capacities is 30.76

a) The expression that shows how many miles Mrs. Ardoin has gone after x hours is of: s(t) = 15t.

b) Mrs. Thomason has been kayaking for x + 1/3 hours.

c) The expression that shows how many miles Mrs. Thomason has gone after Mrs. Ardoin has been riding for x hours: s(t) = 9t + 3.

d) They will meet after half an hour.

The linear functions for the position are defined as follows:

s(t) = vt + s(0).

In which the variables are given as follows:

Mrs. Ardoin is boating at a constant speed of 15 miles per hour, hence his equation is of:

s(t) = 15t.

Mrs. Thomason has been kayaking for a third of an hour more than Mrs. Ardoin, at a rate of 9 miles per hour, hence his initial position is of:

s(0) = 1/3 x 9 = 3 miles.

Thus the equation is of:

s(t) = 9t + 3.

They will meet when:

15t = 9t + 3

6t = 3

t = 0.5.

Hence after half an hour.

The solution to f(x) = g(x) is

x = 0

x = 1

What do you mean by a solution?

We can substitute a value, or values, for a variable (such as x), making the equation true and thus finding a solution. All values of x in the domain, such that f(x) = g, are the solutions if two functions, f, and g, both map to the same co-domain.

as in: x + 2 = 7.

5 + 2 = 7 is what we get when we substitute 5 for x.

Given that 5 + 2 = 7, x = 5 is a solution.

Solution Explained:

A set of values in the table that tell us what the values of each function f(x) and g(x) are for a given value for the variable "x" is already giving us a hint.

We can infer from the table that f(x) decreases when x>0 and moves in the opposite way when x0.

G(x) follows a distinct path; it grows as x increases and shrinks as x lowers.

As a result, there is not much room for equality between the two functions.

You can thus utilize the points shown in the table to begin your test.

f(0)= 0,25 ^ 0=1 since a number raised to 0 is always 0.

g(0)=-0.75 * 0 + 1 = 1

f(1)=0.25^1=0.25 since a number raised to 1 is always equals to itself

g(1)=-0.75*1+1=0.25

So f(x)=g(x), when x=1 and when x=0

It is true that the polynomial is divisible by 6

From the question, we have the following polynomial that can be used in our computation:

Polynomial = x^3+15x^2+74x+120

Answer:

b = 20

Step-by-step explanation:

the variables a and b are proportional , so the equation relating them is

a = kb ← k is the constant of proportion

to find k use the condition a = 12 , b = 3

12 = 3k ( divide both sides by 3 )

4 = k

a = 4b ← equation of proportion

when b = 5 , then

a = 4 × 5 = 20

The percent change for the expression for the given rational number is 28%.

As the stated question-

Original quantity = 175

New quantity = 126

Difference = Original quantity - New quantity

Difference = 175 - 126

Difference = 49

Percentage change = Difference/Original quantity x 100 %

Percentage change =49/175 x 100%

Percentage change = 28%

The slope of a line parallel to the line having equation 10x+12y=-120 is -5/6.

What is the slope of a line parallel to another line?

Parallel lines are coplanar and they never intersect.

Slope is a measure of the angle of a line from the horizontal.

Since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel.

According to the given question:

Given equation of line is 10x+12y=-120

Converting this to slope-intercept form we get

y = -5/6 x + 10

Clearly slope of this line is -5/6

Any line parallel to this line will have the same slope

The value of g is g = w² - 14w + 49, according to the question.

What do you mean by formula?

A truth or a rule expressed using mathematical symbols is the formula. An equal sign is typically used to connect two or more values. When you are aware of the value of one quantity, you can use the formula to determine the value of the other. It facilitates speedy question resolution. Formulas are used in algebra, geometry, and other subjects to speed up and simplify the process of arriving at the result.

According to the given question,

We have :

w = 7 - √g

Firstly isolate the g,

w = 7 - √g

Do the opposite of PEMDAS, first subtract 7 from both sides,,

w (-7) = -√g + 7 (-7)

w - 7 = -√g

Now, multiply -1 (as -√g is the same as -1√g) to both sides

-1(w - 7) = √g

-1w + 7 = √g

To get rid of the square root, you must square both sides,

Note: -1w is the same as -w.

Note: you are squaring all the terms on the other side, not just one.

(-w + 7)² = (√g)²

g = (-w + 7)²

g = (-w + 7)(-w + 7) (note, this can be the answer your teacher wants, or                                            g = (-w + 7)²    )

Use the FOIL method (First, Outside, Inside, Last)

(-w)(-w) = w²

(-w)(7) = -7w

(7)(-w) = -7w

(7)(7) = 49

g = w² - 7w - 7w + 49

Then, simplify (combine all like terms):

g =w² - 7w - 7w + 49

g = w² - 14w + 49

Therefore, the value of g = w² - 14w + 49 .

x² = 9 + -2.25y² + 0.25z² provides a parametric representation of the upper half of the ellipsoid in spherical-like coordinates.

Given,

In response to our inquiry:

Add "-9y²" to each side of the equation.

4x² + 9y² + -9y² + -1z² = 36 + -9y²

9y² + -9y² = 0 when equivalent phrases are combined.

4x² + 0 + -1z² = 36 + -9y²

4x² + -1z² = 36 + -9y²

Add "z²" to both sides of the equation.

4x² + -1z² + z² = 36 + -9y² + z²

Therefore,

x² = 9 + -2.25y² + 0.25z² provides a parametric representation of the upper half of the ellipsoid in spherical-like dimensions.
