What is the standard deviation of the data?

Answers
Answer:
B: 1.53
Step-by-step explanation:
The mean, or average, is 4, and n, the amount of numbers, is 7. To find the standard deviation, first, all of the numbers are subtracted by the mean. This makes (-3, 0, 0, 0, 0, 1, 2). Square all of them to get (9, 0, 0, 0, 0, 1, 4). Next add the squared numbers together (9 + 0 + 0 + 0 + 0 + 1 + 4 = 14). Next, the variance needs to be found. That is found by this formula: (Sum of previous number set ÷ (n - 1)). So in this case, (14 ÷ (n - 1)). Since n is 7, it is (14 ÷ (7 - 1)), or (14 ÷ 6). The answer to that is 2.3 repeating. After the variance is found, it is square rooted to get the standard deviation. √2.3 is about 1.53. Hope this helps! Have a great day! :)

Step-by-step explanation:
In similar triangles, the corresponding angles are congruent.
∠O = R
O = 70°
In ΔOMN,
∠O + ∠M + ∠N = 180 {Angle sum property of triangle}
70 + 50 + Ф = 180

Subtract 120 from both sides,
Ф = 180 - 120

Conner and Alexandra are 260 feet apart when they start walking toward one another. Alexandra walks twice as fast as Conner so whenever Conner travels x feet, Alexandra travels 2 x feet. Let x represent the number of feet Conner has traveled since he started walking toward Alexandra. Write an expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another. 3x Correct Write an expression in terms of x to represent the distance (in feet) between Conner and Alexandra.
Answers
Answer:
i) 3x
ii) d = 260 - 3x
Step-by-step explanation:
Given:
Conner traveled x feet
Alexandra traveled 2x feet
Total distance = 260 ft
i) The expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another will be:
This will be the total number of feet they have walked towards one another
= x + 2x
= 3x
ii) An expression in terms of x to represent the distance (in feet) between Conner and Alexandra.
This will be to find the distance between Conner and Alexandra.
Thus, distance between them will be:
d = 260 - (x + 2x)
d = 260 - 3x

where is ( -3 1/2, -1 1/4 ) on the coordinate plane?
Answers
The point (\(-3\frac{1}{2}\), \(-1\frac{1}{4}\) ) on the coordinate plane is shown in the figure .
The Coordinate plane can be defined as a 2 D plane formed by the intersection of two line ,
where the horizontal line is called x axis and
the vertical line is called y axis .
In the question ,
the point is given
the point is (\(-3\frac{1}{2}\) , \(-1\frac{1}{4}\) )
writing the mixed fraction in decimal form , we get
x coordinate = \(-3\frac{1}{2}\) ⇒ -(3*2+1)/2 = -7/2 = -3.5
y coordinate = \(-1\frac{1}{4}\) ⇒ -(1*4+1)/4 = -5/4 = -1.25
So, the point to be plotted on the coordinate plane becomes (-3.5,-1.25)
the points plotted are shown in the figure below .

Explanation:
Recall that radius is a line segment extending from the center of a circle to the circumference.
Line segment AC extends from the center C of a circle to the circumference.
\(AC=Radius\)Recall that the arc of a circle is defined as the part of the circumference of a circle.
AE is the part of the circumference of a circle.
\(AE=Arc\)Recall that a straight line segment joins and is included between two points on a circle.
D and E are two points on a circle.
A straight line DE line segment joins and is included between two points D and E on a circle.
\(DE=Chord\)Recall that meeting a curve or surface in a single point if a sufficiently small interval is considered a straight line tangent to a curve.
AB is tangent.
\(AB=Tangent\)Recall that an inscribed angle is an angle with its vertex "on" the circle, formed by two intersecting chords.
\(\measuredangle ADE=\text{ Inscribed angle.}\)Recall that a central angle is an angle formed by two radii with the vertex at the center of the circle.
\(\measuredangle ACE=\text{ Central angle}\)Recall that an angle formed by an intersecting tangent and chord has its vertex "on" the circle.
\(\measuredangle\measuredangle CAB=\text{ Tangent Chord Angle}\)Final answer:

Answers
To solve this problem, we have to find the area of the semi circles and the area of the rectangle and add them up together.
The area of the field is equal to 8719.36m^2
Area of the FieldLet us start by finding the area of the rectangle.
Data;
width = 86mlength = 64mArea of a rectangle is given as
\(a = length * width \\a = 86 * 64\\a = 5504m^2\\\)
The area of the rectangle is 5504m^2
Area of the semicircle
The formula of a semi circle is given as
\(A = \frac{1}{2} \pi r^2\)
But since we have two semi circles here, we can simply multiply it by two and the formula becomes
\(A = 2 * \frac{1}{2} \pi r^2\\A = \pi r^2\)
But in the question, we have the diameter of the semi circle as the length of the rectangle.
\(radius = \frac{diameter}{2} \\radius = \frac{64}{2} \\radius = 32m\)
The radius of the semicircle is 32m
Area of the semicircle is
\(A = \pi r^2\\A = 3.14 * 32^2\\A = 3215.36m^2\)
The area of the field is
\(area of field = 3215.36 + 5504\\area = 8719.36m^2\)
The area of the field is equal to 8719.36m^2

What’s Ln(d)=n in exponential form?
Answers
Answer:
ln(d) = n can be rewritten in exponential form as d = e^n.
Step-by-step explanation:
The natural logarithm, denoted by ln, is the logarithm to the base e (approximately 2.718). The inverse of the natural logarithm function is the exponential function e^x. Therefore, when you take the natural logarithm of a number, you can raise e to the power of that number to get the original value.
ln(d) = n is the same as d = e^n
So, Ln(d)=n can be written as d = e^n
This is because e^n is the inverse function of Ln(d) and Ln(d)=n is the logarithm form of d = e^n
Rewrite each expression in an equivalent form with a single exponent.

The equation for the line of best fit is: C. y = 0.894x + 0.535.
How to determine the equation for the line of best fit?In order to determine the equation for the line of best fit, we would create a table of values based on the given x-values and y-values as follows;
x y x² y² xy__
5 4 25 16 20
6 6 36 36 36
9 9 81 81 81
10 11 100 121 110
14 12 196 144 168
Sum 438 398 415
Next, we would calculate the mean of the x and y variables as follows;
Mean = [∑(x)]/n
Mean = 44/5
Mean, \(\bar{x}\) = 8.8
Mean = [∑(y)]/n
Mean = 42/5
Mean, \(\bar{y}\) = 8.4
∑(x - \(\bar{x}\))(x - \(\bar{y}\)) = (5-8.8)(4-8.4) + (6-8.8)(6-8.4)+(9-8.8)(9-8.4)+(10-8.8)(11-8.4)+(14-8.8)(12-8.4)
∑(x - \(\bar{x}\))(x - \(\bar{y}\)) =45.4
∑(x - \(\bar{x}\))² = (5-8.8)²+(6-8.8)²+(9-8.8)²+(10-8.8)²+(14-8.8)²
∑(x - \(\bar{x}\))² = 50.8
Now, we can determine the slope coefficient for the line of best fit:
Slope (b) = 45.4/50.8
Slope (b) = 0.894.
Lastly, we would determine the intercept (a) as follows;
\(a = \bar{y} - b\bar{x}\)
a = 8.4 - (0.894)8.8
a = 0.535
Therefore, the required equation is y = 0.894x + 0.535.
