Answer:
[tex]57\frac{3}{11}[/tex] = c
or
[tex]57.\overline{27}[/tex] = c
Step-by-step explanation:
We know that the diameter of a circle multiplied by [tex]\pi[/tex] is the circumference, so we can create this equation:
180 = c * [tex]\pi[/tex]
Your teacher told us to assume [tex]\pi[/tex] is 22/7, so we'll put that in
180 = c * [tex]\frac{22}{7\\}[/tex]
To get c by itself, we divide both sides by 22/7
[tex]\frac{180}{\frac{22}{7}}[/tex] = c
Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22
180 * [tex]\frac{7}{22}[/tex] = c
Evaluate
[tex]\frac{1260}{22}[/tex] = c
[tex]57\frac{3}{11}[/tex] = c
If you want a decimal instead:
[tex]57.\overline{27}[/tex] = c
In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10/?
Quadratic formula: * = -bt/b? 40c
20
O x=5+31
O x = 51/19
O x = 5+219
O x = 5+2/31
Answer:
[tex]x = 5 \± \sqrt{31}[/tex]
Step-by-step explanation:
Given
[tex]6 = x^2 - 10x[/tex]
Required
The solution in radical form
[tex]6 = x^2 - 10x[/tex]
Rewrite as:
[tex]x^2 - 10x - 6 = 0[/tex]
Using the quadratic formula, we have:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
a = 1
b = -10
c = -6
So, we have:
[tex]x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{100 +24}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{124}}{2}[/tex]
Split the roots
[tex]x = \frac{10 \± \sqrt{4 * 31}}{2}[/tex]
Express [tex]\sqrt 4[/tex] as 2
[tex]x = \frac{10 \± 2\sqrt{31}}{2}[/tex]
Split the fraction
[tex]x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}[/tex]
[tex]x = 5 \± \sqrt{31}[/tex]

Worksheet Difficulty: 2 Intermediate Learning Objective: 09-02 Compute and interpret a confidence interval for a population mean.
Answer:
a) t = 2.2010
b) t = 1.7291
c) t = 3.4995.
Step-by-step explanation:
a. The sample size is 12 and the level of confidence is 95%.
12 - 1 = 11 degrees of freedom, either two-tailed test at [tex]\alpha = 0.975[/tex] or one-tailed test at [tex]\alpha = 0.95[/tex], so t = 2.2010.
b. The sample size is 20 and the level of confidence is 90%.
20 - 1 = 19 degrees of freedom, either two-tailed test at [tex]\alpha = 0.95[/tex] or one-tailed test at [tex]\alpha = 0.9[/tex], so t = 1.7291.
c. The sample size is 8 and the level of confidence is 99%.
8 - 1 = 7 degrees of freedom, either two-tailed test at [tex]\alpha = 0.995[/tex] or one-tailed test at [tex]\alpha = 0.99[/tex], so t = 3.4995.

Answer:
([tex]\frac{5}{2}[/tex], 3)
Step-by-step explanation:
I got 5/2 as my x variable and 3 for my y variable to being the midpoint. In which I added both my x variables provided ( 3 and 2 ) and then I divided them by two to get half of that (since you are looking for in between those two digits technically so you are wanting to find the midpoint or the middle of that line segment). I also did the same with the two y variables as well which were 7 and -1, then I divided both by two to get the variable 3.

What is the definition of independent samples? A. All samples of the same size have an equal chance of being selected from the population. B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population. C. The sample selected from one of the populations is paired with a sample selected from the other population.
Answer:
B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
Step-by-step explanation:
In statistical analysis, the use of independent samples for diverse studies is common.
Independent samples are such that the sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
This means that samples are selected randomly in such a way that an observation obtained from a sample does not depend on the values obtained from the observation of another sample from the other population.
3.Write the equation of the line best fit
Answer: y = -5/8x + 6
Step-by-step explanation: The line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. The line of best fit is already given in this specific question, and we just have to figure out the equation of that line. The equation can be determined using the equation y=mx+b, where "y" represents the output, "m" represents the slope (vertical change compared to the horizontal change), "x" represents the input, and "b" represents the y-intercept (where the line crosses the y-axis). Since the slope (rise over run) is -5/8 and the y-intercept is (0,6), the equation of the line of best fit is y=-5/8x+6.

what is the range of f?
Answer:
Range is [tex]-5 \le y \le 5[/tex]
Range in interval notation is [-5, 5]
==========================================================
Explanation:
Refer to the diagram below. As marked in red, the smallest y value is y = -5. The largest y value is y = 5. The range is the set of y values between these endpoints, including both endpoints.
We can say the range is [tex]-5 \le y \le 5[/tex]
In interval notation, we write that as [-5, 5]. The use of square brackets tells the reader that the endpoints are included as part of the range.

What are similar triangles?Those triangles look the same but are different in size.
And in similar triangles,
the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.
Given:
The triangles ABC and XYZ are similar triangles by the SSS criterion.
And AB/XY = 4/2
AC/XZ = √52/√13
The missing ratio is YZ/BC = 6/3
It will complete the SSS criterion.
Therefore, YZ/BC = 6/3 is the missing term.

Answer:
48°60°72°Step-by-step explanation:
The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:
4×12° : 5×12° : 6×12° = 48° : 60° : 72°
Angles 1 to 3 are 48°, 60°, 72°, respectively.
