Answer:

24

Step-by-step explanation:

3a/6 = 12

3a = 6 * 12

3a = 72

a = 72/3

a = 24

Check:

3*24/6 = 12

72/6 = 12

   For numbers 5 and 20 the value of the geometric mean of these numbers is

Gm (5, 20) = 10

      The definition of geometric mean is a calculation that is performed on a set of numbers which consists of calculating the square root of the product between them, the equation is as follows:

Gm (a,b) = √ab

  Then in our case that we have the values 40 and 15, these are equivalent to the variables a and b

Solving the problem with the arithmetic progression, the 32nd term of the sequence is 558.

Arithmetic progression is a sequence of numbers in which the next term is depicted by adding a fixed number 'd' to the preceding term. The series is in arithmetic progression.

We all know the formula for arithmetic progression is,

aⁿ = a + ( n-1 ) d

where d = difference between two corresponding terms, n = no. of term, a = first term

We have to find the 2nd term, and it's, a³⁸ = 3 + ( 38 - 1)( 18 - 3 ) = 3 + 37× 15 = 3 + 555 = 558.

The scalar multiplication [tex]k(\overrightarrow{a}+\overrightarrow{b})=k\overrightarrow{a}+k\overrightarrow{b}[/tex]has been proved.

Scalar Multiplication Property:

Basically a scalar means the real number.

The scalar multiplication property states that the product of a sum or difference of a number is equal to the sum or difference of the products.

The general form of scalar multiplication as follows:

k (A + B) = kA + k B

where

k is the scalar.

Given,

Let

[tex]\overrightarrow{a}= < x_1,y_1 >[/tex]

and

[tex]\overrightarrow{b}= < x_2,y_2 >[/tex]

Then we have to prove the following scalar multiplication property,

[tex]k(\overrightarrow{a}+\overrightarrow{b})=k\overrightarrow{a}+k\overrightarrow{b}[/tex]

We know that,

"The vector is an object that has both a magnitude and a direction. And  vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction."

Here we have two vectors like [tex]\overrightarrow{a},\overrightarrow{b}[/tex].

Now we need to use the definition of the scalar multiplication property,

Then, the LHS of the expression is written as,

[tex]\implies k(\overrightarrow{a}+\overrightarrow{b})[/tex]

Apply the values of the vectors then we get,

=> k(<x₁, y₁> + <x₂, y₂>)

When we expand the terms then we get,

=> k<x₁, y₁> +  k<x₂, y₂>

And it can be written as,

[tex]\implies k\overrightarrow{a}+k\overrightarrow{b}[/tex]

Therefore, the scalar multiplication property has been proved.

   From the list of numbers presented we can determine that this is a finite sequence.

 A sequence is defined by an order of values and/or elements that have a relationship of variation as a ratio or proportion that makes them predictable.

  A sequence maintains an order, and this numerical order can be finite or infinite, in the given case we have the following list:

2.3 + 4.6 + 9.2 +18.4

   We can clearly notice that we have a larger limit number and it is 18.4, as we know the beginning of the sequence and the exact end we can know that we are in the presence of a finite sequence.

Part a - C = 120 + 5x

Part b - A = [120 + (5 x (x)] / x

Part c - The number of hours you must play before the average cost per hour drops to $10 per hour is 15 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Membership fees = $120

Cost per hour = $5

x = number of hours

The equation that represents the total cost:

C = 120 + 5x

The equation that represents the average cost per hour:

A = [120 + (5 x (x)] / x

From the graph, we can assume that the y-axis indicates the average cost per hour and the x-axis indicates the number of hours.

We see that in 16 hours the average cost per hour is $10 so the number of hours to play before the average cost per hour drops to $10 per hour is 15 hours.

Thus,

Part a - C = 120 + 5x

Part b - A = [120 + (5 x (x)] / x

Part c - The number of hours you must play before the average cost per hour drops to $10 per hour is 15 hours.

Answer:

y = 3x + 1

y = -x + 5

Step-by-step explanation:

Take the system of equations and substitute (1 ,4) in any one of the equations. If both the sides are justified, then (4,1) is the solution to that pair of equations.

  1) y = -3x  - 1   ---------(I)

     y = -x + 5

Substitute (1,4) in equation (I)

        4 = -3*1 - 1

        4 = -3-1

        4 ≠ -4

So, (1, 4) is not a solution.

2) y = 3x + 1   ---------------(II)

   y = - x + 5

Substitute (1 ,4) in equation (II)

      4 = 3*1 + 1

       4 = 3 + 1

       4 =  4

(1 ,4) is the solution for this system of equation.

The correct option regarding the linear regression equation is:

No, the equation is not a good fit because the sum of the residuals is a large number.

To find the equation, we need to insert the points (x,y) in the calculator.

In possession of the equation, the residuals are given by the difference of the predicted values(with the equation) and the actual values.

The model represents a good fit if the sum of the residuals is close to 0.

For this problem, the sum of the residuals is given by:

90 - 50  - 100 - 100 + 150 - 50 = -60.

The sum is a large number, hence the model is not a good fit.

Answer:

121° and 59°

Step-by-step explanation:

We'll assign the two angles 'a' and 'b'. Since they are supplementary, this means they add to 180°. We can model this peoblem with the expressions:

a + b = 180° and a - b = 62°

Let's use the second equation to find a substitution for a:

a - b = 62°

a = 62° + b

Now substitute this in the first equation and solve:

(62° + b) + b = 180°

62° + 2b = 180°

2b = 118°

b = 59°

59° + 62° = 121° this is angle a

The sampling technique Greg used is stratified sampling.

Stratified sampling is used when the population is more heterogeneous. Then we divide the population into subgroups or strata which will be more homogeneous and take samples from each strata. This will ensure the equal representation from each group in population. Stratified sampling helps to reduce the variability of the estimates also.

Here the population of current season ticket holders consist both for men's basketball games and women's basketball games. So Greg considered both as separate subgroups of the population and collected random samples of size 100 from each group. This technique for sampling is known as stratified sampling.

The inverse function as g⁻¹ (h)  = [(h+6)/10]² which is the correct answer would be an option (E).

The inverse function is defined as a function obtained by reversing the given function.

To determine the inverse of a function, all you have to do is switch where h and g are and resolve for g.

So after switching h and g,

g = g(h) = 10√h - 6

becomes

h = 10√g - 6

Now, we solve for h regularly.

h + 6 = 10√g

(h + 6)/10 = √g

[(h+6)/10]² ⇒ g = [(h+6)/10]² = g(x)

Therefore the inverse of g(x) is g⁻¹ (h)  = [(h+6)/10]²

Hence, the inverse function as g⁻¹ (h)  = [(h+6)/10]²
