Answer: Lin is the most consistent and I would want to have them on my team.
Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since
range = max - min
So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

[tex]x=140[/tex]
Step-by-step explanation:
Do not get grounded.
An angle at a point is 360°.
So, [tex]x+120+70+30=360[/tex]
[tex]x+220=360[/tex]
[tex]x=140[/tex]
Remember this All the angles around a point when added gives a 360° !
Thus,
30+ X +70+120 = 360
=> X + 220 = 360
=> X = 140°Write an equation of a line that is perpendicular toy-2/3%+2

If a desk is $186with a discount of 50% what is the original retail price for the desk
Answers
Answer: $372
Step-by-step explanation:
Let the original retail price be 'x'
Therefore, using the give information, we can form the following equation:
50/100x = 186
Now, solve for x
50/100x = 186
1/2x = 186
x = 186 * 2
x = 372
The original retail price is $372.
Check:
50/100(372) = 186
1/2(372) = 186
186 = 186

We know that the perimeter of a square is [tex]2l + 2w[/tex], where l is the length and w is the width.
We also know that the perimeter of a triangle is all of its sides added up.
Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.
Basically:
[tex](3x - 3) + (3x - 3) + (x - 3) + (x - 3) = (2x - 1) + (2x - 1) + (2x)[/tex]
We can combine like terms to get a less scary equation.
[tex]8x - 12 = 6x - 2[/tex]
Our goal is to now isolate x so we can find it's value.
Add 2 to both sides:
[tex]8x - 10 = 6x[/tex]
Subtract 6x from both sides:
[tex]2x - 10 = 0[/tex]
Add 10 to both sides:
[tex]2x = 10[/tex]
Divide both sides by 2:
[tex]x = 5[/tex]
Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.
Let's do it on the triangle.

Find the distance between the points (9,-6) and (4,-7)
Answers
Answer:
The answer is option DStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(9,-6) and (4,-7)
The distance between them is
[tex]d = \sqrt{ ({9 + 4})^{2} + ( { - 6 - 7})^{2} } \\ = \sqrt{ {13}^{2} + ({ - 13})^{2} } \\ = \sqrt{169 + 169} \\ = \sqrt{338} \\ = 13 \sqrt{2} [/tex]

A student makes a number of measurements of electrical current in the circuit. The average of the measurements is 12.33 mA. The standard deviation of the sample is 0.14 mA. How should this measurement be written to the correct number of significant figures with error range to show a 95% confidence
Answers
Answer:
The way to represent this it is
[tex] 12.33 - \frac{0.27}{\sqrt{n} } < \mu < 12.33 + \frac{0.27}{\sqrt{n} } [/tex]
Step-by-step explanation:
From the question we are told that
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
[tex]\alpha = (100-95)[/tex]
[tex]\alpha = 0.05[/tex]
The critical value for [tex]\frac{\alpha }{2}[/tex] is obtained from the normal distribution table that value is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Now the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]
[tex]E = \frac{0.27}{\sqrt{n} }[/tex]
Now the error range to show a 95% confidence is mathematically represented as
[tex]\= x - E < \mu < \= x + E[/tex]
[tex] 12.33 - \frac{0.27}{\sqrt{n} } < \mu < 12.33 + \frac{0.27}{\sqrt{n} } [/tex]
Here notice that the significant figure is keep to three to match the significant figure of the given values
