Suppose that a company wishes to predict sales volume based on the amount of advertising expenditures. The sales manager thinks that sales volume and advertising expenditures are modeled according to the following linear equation. Both sales volume and advertising expenditures are in thousands of dollars.
Estimated Sales Volume=46.41+0.45(Advertising Expenditures) If the company has a target sales volume of $200,000 how much should the sales manager allocate for advertising in the budget? Round your answer to the nearest dollar.
The sales manager should allocate approximately 341311.111 for advertising in the budget.
What is advertising expenditure?Generally, Advertising expenditure refers to the amount of money that a company or organization spends on promoting their products or services through various forms of advertising media, such as television, radio, print, and online.
This can include costs for creating and producing advertisements, as well as fees for placing them on different platforms. Advertising expenditure can also be referred to as "advertising budget" or "advertising spend."
To find the advertising expenditure needed to reach a target sales volume of $200,000, we can use the equation provided: Estimated Sales Volume = 46.41 + 0.45(Advertising Expenditures)
We can set the target sales volume as the left-hand side of the equation and solve for the advertising expenditure:
200,000 = 46.41 + 0.45(Advertising Expenditures)
Subtracting 46.41 from both sides:
153,590 = 0.45(Advertising Expenditures)
To find the Advertising Expenditures, divide 153,590 by 0.45:
Advertising Expenditures = 341311.111

What type of line is Y 0?
If the value of y = 0, then it make the straight line on the graph.
The term graph in math is defined as the way that is used to represent a set of data to make it easier to understand and interpret statistical information.
Here we have the expression y = 0.
And here we know that the y coordinate is constant which is 0 for given equation and only x coordinate is variable.
Therefore it represent the x-axis.
Therefore, basically y=0 is the linear equation to denote the x - axis, here as all the points on the x- axis, then we have their y co-ordinate = 0.

The sampling distribution of dis normal.
B
The sampling distribution of d is binomial.
с
The sampling distribution of dis uniform.
d is unbiased.
E

Using the Central Limit Theorem for proportions, the correct option is:
E. The statistic is biased.
In plain English, what is the central limit theorem?
According to the central limit theorem, even if a population isn't normally distributed, you may still obtain sufficiently big samples from it and have the samples' means be distributed normally.
What is the central limit theorem and why is it significant?
Because of the Central Limit Theorem, we can confidently assume that the sampling distribution of the mean will be normally distributed in most situations.
Since a normal distribution is assumed, we can benefit from statistical methods, as we will see in the section after this one.

From the given data, the first and third graph are correct.
1. For the first graph,
the two equation are -
y = -2x - 4
-4x + y = 2
Let us check the common points for the given graph,
(-1,-2)
y = -2x - 4 - 4x + y = 2
-2 = -2(-1) - 4 -4(-1) + (-2) = 2
-2 = -2 2 = 2
Hence it is correct.
2. For the second graph,
y = -3/2x - 2
y = -1/4x + 3
Common points are - (4,4)
y = -3/2x - 2 y = -1/4x + 3
4 ≠ -8 4 ≠ 2
Hence it is not correct.
3. For the third graph,
y = -5
y = 3x + 1
Common points are - (-2,-5)
y = 3x + 1
-5 = -5
Hence it is correct.

What additional information would be necessary to determine sin a without using the Pythagorean theorem explain brainly?
The Pythagorean Theorem, often known as Pythagoras Theorem, is a crucial concept in mathematics that describes how the sides of a right-angled triangle relate to one another. Pythagorean triples are another name for the sides of the right triangle. Here, examples help to demonstrate the formula and proof of this theorem.
In essence, the Pythagorean theorem is used to determine a triangle's angle and length of an unknown side. This theorem allows us to obtain the hypotenuse, perpendicular, and base formulae.
In order to determine sin a without using the Pythagorean theorem, we will need to have the value of the opposite side and angle. Sin (a) = opposite / hypotenuseHere, the hypotenuse is not given, so we will need to have the value of the opposite side and angle (a) in order to determine sin a without using the Pythagorean theorem.

the circus admits children for $2 each and adults for $5 each. how many of each ticket were sold if 160 tickets were sold for $476
Answer: Children = 108
Adult = 52
Step-by-step explanation:
Let x = number of children
Let y = number of adult
Based on the information given, we can form an equation which will be:
x + y = 160 ........ i
2x + 5y = 476 ........ ii
Multiply equation i by 2
Multiply equation ii by 1
2x + 2y = 320 ....... iii
2x + 5y = 476 ........ iv
Subtract iii from iv
3y = 156
y = 52
Number of adults = 52
Since x + y = 160
x + 52 =160
x = 160 - 52
x = 108
Number of children = 108

. The ratio of the area of circle A to the area of circle B is 12/5. What is the ratio of their circumferences?
Answer:
1.5
Step-by-step explanation:
a : b = 1 : 12/5
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
Let the radius of circle a = 1
Area of circle A = 1π
Radius of circle A = square root of 12/5 = 1.5
The circumference of a circle = 2nr
n = 3.14
circumference of circle A = 2 x n x 1 = 2n
circumference of circle B = 2 x n x 1.5 = 3n
ratio of circumference = 3n / 2n = 1.5

How many cars had exactly two of the given options
24 cars lacked power steering but did have air conditioning and an automatic gearbox.
According to the question,
No. of cars with Air conditioning = 88
No. of cars with Automatic transmission = 96
No. of cars with power steering = 76
All three = 4
None of these extras = 19
Only air conditioning = 23
Only automatic transmissions = 61
Only power steering = 28
Power steering and automatic transmission both = 11

In Lewis County , there were 2 , 277 student athletes competing in spring sports in 2014 . That was 110% of the number from 2013, which was 90% of the number from the year before. How many student athletes signed up for a spring sport in 2012
In the spring of 2012, 2300 student athletes participated in a sport.
How do I calculate a percentage?The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.
In 2014, there were 2277 student athletes participating in spring sports.
Suppose there were x contestants in 2013.
The answer was 2277, which was 110 percent more pupils competing in 2014 than in 2013. So,
[tex]$110 \%$ of $\mathrm{x}=2277$$\frac{110}{100} \times \mathrm{x}=2277$$\mathrm{x}=\frac{2277 \times 100}{110}$$\mathrm{x}=2070$[/tex]
2070 pupils therefore competed in 2013.
Let y be the student who will be vying in 2012.
Now, the number of pupils competing in 2070 was 90% that of the year 2012's.
So,
[tex]$90 \%$ of $y=2070$$$\begin{aligned}& \frac{90}{100} \times y=2070 \\& y=\frac{2070 \times 100}{90} \\& y=2300\end{aligned}$$[/tex]

make up an equation in the form of an y=kx +b, the graph which passes through the following points: (5,5) and (-10,-19)
Answer:
y = 8/5x - 3
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
(y2 - y1) / (x2 - x1)
(-19 - 5) / (-10 - 5)
-24 / -15
= 8/5
Plug in the slope and a given point into y = mx + b, and solve for b
y = mx + b
5 = 8/5(5) + b
5 = 8 + b
-3 = b
Plug in the slope and b into y = mx + b
y = 8/5x - 3
So, the equation is y = 8/5x - 3
Explain why the initial value of any function of the form
f(x)= a(b) is equal to a.
Hello there!
Initial value is the y-intercept so x = 0. Then b⁰ = 1 because x⁰ = 1 if x ≠ 0. So the value of function is a * 1 which is equal to a.
Step-by-step explanation: The initial value of any function of the form f(x)= a(b) is equal to a because this type of function is a linear equation, which means that the rate of change (slope) is constant. This means that the output is always equal to the input multiplied by a constant, which is the coefficient a. Therefore, when the input (x) is equal to 0, the output (f(x)) is equal to 0 multiplied by a, which is equal to a.
