using statistics helps us make decisions based on what kind of evidence?
Using statistics helps us make decisions based on empirical evidence, which is obtained through data analysis and inference.
Statistics provides us with a set of tools and methods to collect, analyze, and interpret data. By applying statistical techniques, we can make decisions based on evidence derived from empirical observations and measurements.
Statistics allows us to summarize and describe data, identify patterns and relationships, and draw conclusions from samples or populations. It helps us quantify uncertainty and assess the strength of evidence supporting different claims or hypotheses.
Decision-making based on statistics involves making inferences about a larger population based on the information available from a sample. By using probability theory and statistical models, we can estimate population parameters, test hypotheses, and make predictions about future events or outcomes.
Statistics provides a systematic and rigorous framework for evaluating evidence and reducing bias in decision-making. It allows us to objectively assess the reliability and validity of information, making decisions that are informed by data-driven analysis rather than intuition or anecdotal evidence.
In summary, statistics helps us make decisions based on evidence obtained through data analysis, enabling us to draw reliable conclusions, quantify uncertainty, and make informed choices in various fields such as business, medicine, social sciences, and more.

Flora wants to create a scale drawing of
the Empire State Building on an 8 inch
by 11 inch piece of paper. She wants the
drawing to be as large as possible. Which
shows the scale she should use?
Length- 1,792
With- 195
Answer:
The scale drawing is 1 centimeter to 50 meters ⇒ answer E
Step-By-Step Explanation:
* Lets explain how to solve the problem
- The height of the empire state building is about 1450 feet long and
400 feet wide
- Andre wants to make a scale drawing of the front view of it on an
8 1/2 inches by 11 inches piece of paper
- We need to select one of these scales that we think is the most
appropriate for the scale drawing
A. 1 inch to 1 foot
B. 1 inch to 100 feet
C. 1 inch to 1 mile
D. 1 centimeter to 1 meter
E. 1 centimeter to 50 meters
F. 1 centimeter to 1 kilometer
- For scale A , B , and D the scaled image will not fit the page
- For scale C and F the drawing will be very small because 1 mile
is 5280 feet and 1 kilometer is 3280.84 feet
- E is most appropriate because 1 meter is 3.28084 feet, then the
height of the empire state is 442 m dividing by 50 m gives about
8.8 cm and the height of the paper is 11 inches which is about 28 cm
and the width of the empire state is about 122 m dividing by 50 m
gives about 2.5 cm and the width of the paper is 8 1/2 inches which
is about 22 cm then the drawing will be appropriate for drawing
∴ The scale drawing is 1 centimeter to 50 meters

The equation of a circle with its center at the origin and passes through the point (5,0): x2+y2=25
the equation of a circle of with the center (2,3) and containing the point (3,2): x2+y2=2
What is Origin ?Origin is referred to as the first point or the starting point from which we begin our calculations or measurements in mathematics, particularly in the subject of coordinate geometry. The 0 on a ruler is the point at which we begin taking measurements; as a result, it is referred regarded as the scale's origin.
(x-h)^2+(y-k)^2=r2
is the equation for a circle with center (h,k) and radius (r).
This yields the more well-known equation
x2+y2=r2
for a circle centered at the origin.
Since we are aware that the circle's center is at its origin, i.e.
This fact, together with the circle's intersection point (5,0), can be used to determine the radius. The distance formula is used for this.
r=√(x2−x1)^2+(y2−y1)^2
In light of (0,0) and (5,0):
r=√(5−0)^2+(0−0)^2
=√25+0
√25=5
⇒ r=5
Therefore, x^2+y^2=(5)^2
x2+y2=25 is the equation for the circle.
(x-h)^2+(y-k)^2=r2 is the equation for a circle with center (h,k) and radius (r).

Since we are aware that the circle's center is at (2,3), i.e.
This fact, together with the circle's intersection point (3,2), can be used to determine the radius. The distance formula is used for this.
r=√(x^2−x1)^2+(y2−y1)^2
In light of (2,3) and (3,2):
r=√(3−2)^2+(2−3)^2
r = √(1)^2+(-1)^2
= √1+1
=√2
⇒ r=√2
Therefore, x2+y2=(√2)^2

Sheri has $15,200 to invest in mutual funds and in bonds. sheri has selected a mutual fund that earns 1% a year and a bond that earns 4% a year. if she wants to earn $548 at the end of the first year, how much does she need to invest into each type of account?
Sheri should invest $2000 in mutual fund and $13,200 in bond.
Let the amount to be invested in mutual fund be x. So, the amount to be invested in bond will be (15,200 - x). Forming the equation now -
1%×x + 4%×(15,200 - x) = 548
x/100 + 60,800/100 - 4x/100 = 548
60,800 - 3x = 54800
3x = 60800 - 54800
3x = 6000
x = 6000 ÷ 3
x = 2000
Amount to be invested in mutual fund = $2000
Amount to be invested in bond = 15,200 - 2000
Amount to be invested in bond = $13,200
Sheri should invest $2000 and $13,200 in mutual fund and bond respectively.

Explanation:
Considering the given functions for a(x)
1. To solve for a(8), we'll have to use the third function since we're given that x > 1 in the 3rd function and we know that 8 is greater than 1.
So we'll have;
\(\begin{gathered} a(x)=-4x+7_{} \\ a(8)=-4(8)+7 \\ a(8)=-32+7 \\ a(8)=-25 \end{gathered}\)3. To solve for a(-7), we'll use the 1st function because -7 is less than -6 and the condition is x <= -6;
\(\begin{gathered} a(x)=|x-8| \\ a(-7)=|-7-8| \\ a(-7)=|-15| \\ a(-7)=15 \end{gathered}\)5. a(-1/2)
In this case, we'll use the 2nd function is -1/2 lies between -6 and 1.
So, we'll have;
\(\begin{gathered} a(x)=2x-x^2 \\ a(-\frac{1}{2})=2(-\frac{1}{2})-(-\frac{1}{2})^2 \\ =-1-(\frac{1}{4}) \\ =\frac{-4-1}{4} \\ =-\frac{5}{4} \end{gathered}\)help will give brainiest

Find the mean,median,mode, and range:5,2,5,2
Answer:
Mean = 3.5
Median = 3.5
Mode = 5, 2
Step-by-step explanation:
Hope that helps!
Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:
Mean: (5 + 2 + 5 + 2)/4
= (14)/4
= 3.5
Mean = 3.5
Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):
Median: (2 + 5)/2
= 7/2
= 3.5
Median: 3.5
Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.
Mode: None.
Range: The Range is found by subtracting the greatest number with the least number:
5 - 2 = 3
Range: 3

If f(x)=x+x1,prove that [f(x)]3=f(x3)+3f(x1).
To prove that [f(x)]3 = f(x3) + 3f(x1), we can use the binomial theorem. According to the theorem, for a binomial equation of the form (x + y)n, the result will be the sum of all the terms of the expansion of that equation, which can be determined using the equation:
(x + y)n = Σk=0n(nCk) xn-kyk
Here, nCk is the binomial coefficient, and is calculated as n! / (k! (n-k)!).
For our equation, we have x = f(x), y = f(x1) and n = 3. Substituting these values in the equation, we get:
[f(x)]3 = Σk=03(3Ck) f(x)3-kf(x1)k
When k = 0, the equation simplifies to [f(x)]3 = f(x3) and when k = 3, the equation simplifies to [f(x)]3 = 3f(x1).
By adding these two equations, we can get the final equation: [f(x)]3 = f(x3) + 3f(x1)
Hence, we have successfully proved the statement.

What is the equation of the line that passes through the point (5, 4) and has a slope
of 6/5
Answer:
y = (6/5)x -2
Step-by-step explanation:
Answer:
y = 6/5x - 2
Step-by-step explanation:
In this question, we have to find the equation of the line with the given information.
We know that the the slope is 6/5 and it passes through the point (5, 4)
Lets represent this problem in slope intercept form with just the slope, since we need to find the "y-intercept".
y = 6/5x + b
To find the y-intercept, plug the values of the coordinate into the equation and solve for b:
4 = 6/5(5) + b
Solve for b:
4 = 6/5(5) + b
4 = 30/5 + b
4 = 6 + b
Subtract 6 from both sides to get "b" by itself.
-2 = b
This means that the y-intercept would be -2
When we put in into our slope intercept equation, it should look like this:
y = 6/5x - 2
y = 6/5x - 2 would be the equation of the line
What is the standard equation of a line calculator?

What is the solution of the integral function?The solution of the integral function is calculated as follows;
The given integral function;
\(\int\limits^2_1 {(\frac{1}{x^2} - \frac{1}{x^3} )} \, dx\)
The values of the integrands is also given as;
\(\int\limits^2_1 {\frac{1}{x^2} } \, dx= \frac{1}{2}\)
\(\int\limits^2_1 {\frac{1}{x^3} } \, dx= \frac{3}{8}\)
The given integral function can be expanded as follows;
\(\int\limits^2_1 {(\frac{1}{x^2} - \frac{1}{x^3} )} \, dx = \int\limits^2_1 {\frac{1}{x^2} } \, dx \ - \int\limits^2_1 {\frac{1}{x^3} } \, dx\)
From the given values of the integrands, we can substitute their values into the expanded integral function as follows;

A graphing calculator is recommended. Find the maximum and minimum values of the function. (Round your answers to two decimal places.) y = sin x + sin 2x maximum value minimum value
The maximum value of the function is approximately 1.724 and the minimum value is approximately -1.724.
To find the maximum and minimum values of the function y = sin x + sin 2x, we can first take its derivative with respect to x:
y' = cos x + 2 cos 2x
Then, we can set y' equal to zero and solve for x:
cos x + 2 cos 2x = 0
We can use a graphing calculator to find the solutions to this equation, which are approximately x = 0.285 and x = 2.857. We can then evaluate the original function at these values to find the maximum and minimum values:
y(0.285) ≈ 1.724
y(2.857) ≈ -1.724
Therefore, the maximum value of the function is approximately 1.724 and the minimum value is approximately -1.724.

consider the surface s : f(x,y 0 where f (x,y) = (e^x -x)cos y find the vector that is perpendicular to the level curve
Vector that is perpendicular to the level curve at the point (a, b) is the opposite of the gradient vector:
-∇f(a, b) = (\(-e^a\) + 1, a sin b)
How to find the vector that is perpendicular to the level curve of the surface?We can use the gradient of f(x, y) at that point.
The gradient of f(x, y) is given by:
∇f(x, y) = ( ∂f/∂x , ∂f/∂y )
So, we have:
∂f/∂x = \(e^x\) - 1
∂f/∂y = -x sin y
At the point (a, b), the gradient vector is:
∇f(a, b) = ( \(e^a\) - 1 , -a sin b )
The level curve of f(x, y) is the set of points (x, y) where f(x, y) = k for some constant k. In other words, the level curve is the curve where the surface s intersects the plane z = k.
Let (a, b, c) be a point on the surface s that lies on the level curve at the point (a, b). Then, we have:
f(a, b) = c
Differentiating both sides with respect to x and y, we get:
∂f/∂x dx + ∂f/∂y dy = 0
This equation says that the gradient vector of f(x, y) is orthogonal to the tangent vector of the level curve at the point (a, b).
Therefore, the vector that is perpendicular to the level curve at the point (a, b) is the opposite of the gradient vector:
-∇f(a, b) = (\(-e^a\) + 1, a sin b)
