Is a measure of 27 inches "far away from a mean of 15 inches? As someone with knowledge of statistics, you answer it depends and request the standard deviation of the underlying data.
(a) Suppose the data come from a sample whose standard deviation is 3 inches. How many standard deviations is 27 inches from 15 inches?
(b) is 27 inches far away from a mean of 15 inches?
(c) Suppose the standard deviation of the underlying data is 7 inches. Is 27 inches far away from a mean of 15 inches?
(a) 27 inches is standard ____ deviation(s) away from 15 inches.
(Type an integer or decimal rounded to one decimal place as needed.)
In the graph above, what's the distance between (5, –2) and (5, 3)?
Answer:
5
Step-by-step explanation:
To find the distance between two points, subtract the two values and find the absolute value. So in this question, our equation would be |-2-3| which equals |-5| which then solves to 5.
solve equation:
2x-26=0
Answer:
x = 13
Step-by-step explanation:
You want to solve for x, so move anything not including x to the other side of the equal sign. In this problem, you want to add 26 to zero to move it.
Now your equation will look like 2x = 26
Divide both sides by 2 to solve for x
x = 13

Ceri has gained weight.
She now weighs 55 kg, which is 10% higher than her normal weight.
What is Ceri's normal weight?
Answer:
I believe her weight is 80kg
Step-by-step explanation:
Ceri normal weight is 50 Kg.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Present Weight = 55 Kg, which is 10% higher than her normal weight.
let her normal weight be x.
So, x+ 10% of x = 55
x+ 1/10 x = 55
11x /10 = 55
11x= 550
x= 50
Hence, Ceri normal weight is 50 Kg.

Answer:
1 , 4 , -14000 in the first three boxes
-2 , -5 , 200000 in the bottom three boxes
Step-by-step explanation:
Recall that the values shown in the augmented matrix that you are given represent the coefficients used in the following equations:
[tex]1\,x_1+0\,x_2-1\,x_3-4\,x_4=-14000\\and\\0\,x_1+1\,x_2+2\,x_3+5\,x_4=200000[/tex]
Therefore, you can solve for x1 in the first equation, and for x2 in the second one , and then complete the boxes that you are presented with, using the coefficients that accompany each variable, and the last box is for the constant value (pure number term). Then you need to first solve for the given variables, and then use the coefficients found to input their values in the boxes:
[tex]x_1=1\,x_3+4\,x_4-14000\\and\\x_2=-2\,x_3-5\,x_4+200000[/tex]
So, please type in the first row of boxes, the numbers:

A soft drink bottling company fills and ships soda in plastic bottles with a target volume of 354 milliliters. The filling machinery does not deliver a perfectly consistent volume of liquid to each bottle, and the three quartiles for the fill volume are Q1 = 351, Q2 = 355. and Q1 = 357. A fill volume of 353 ml. is considered low. Would a fill volume of 353 ml. be considered an outlier?
A. No
B. Yes
Answer:
No
Step-by-step explanation:
Given the following quartile values :
Q1 = 351, Q2 = 355. and Q3 = 357
Values below : Q1 - 1.5*IQR
Values above : Q3 + 1.5*IQR
IQR = Q3 - Q1
IQR = 357 - 351 = 6
THEREFORE ;
Lower boundary = 351 - (1.5 * 6) = 351 - 9 = 342
Upper boundary : 357 + (1.5 * 6) = 357 + 9 = 366
Hence, any value below the lower boundary value or above the upper boundary value would be considered an Outlier. Only values which lie within the lower and upper boundary values are not considered as outliers.
Therefore, a fill volume of 353 mL will not be considered an Outlier as it lies in between the lower and upper boundary values.
Given that CD is the perpendicular bisector of AB, which of the following statements can be used to show that AC=BC?
Answer:
B. ΔAXC ≅ ΔBXC by SSS, so AC ≅ BC because they are corresponding parts of congruent triangles.
Step-by-step explanation:
From the given diagram, XC is common to ΔAXC and ΔBXC.
And it can be observed that CD divides AB into two equal length segments.
Thus,
AX ≅ BX (bisection property of a line)
AC ≅ BC (congruence property of triangles)
Therefore, the congruence relationship between triangles ΔAXC and ΔBXC would be, Side-Side-Side (SSS) so as to show that AC ≅ BC.
3. For the polynomial g(x) = x^4 - 8x^3 + 23^2 - 26x + 10, you are told that the zeros include x=1, x = -3 + i, and x = 3+i.
Explain how you know this list is incorrect. Then you are told that two of the given zeros are correct, with one of them having a multiplicity of 2. Use this information to determine all zeros of g(x). Be sure to show and explain all steps.
Step-by-step explanation:
If the polynomial has complex roots, the conjugates of those complex roots must also be part of the zeroes.
Therefore x = -3 - i and x = 3 - i are also zeroes of g(x). However this means that g(x) has 5 solutions when the degree of g(x) is 4. This is impossible, and hence the list is incorrect.
If either of the complex roots (x = -3 + i or x = 3 + i) had a multiplicity of 2, their conjugates will also have a multiplicity of 2, which is impossible as discussed previously.
Therefore x = 1 has a multiplicity of 2.
We have
x⁴ - 8x³ + 23x² - 26x + 10 = (x - 1)²(Ax² + Bx + C).
= (x² - 2x + 1)(Ax² + Bx + C)
= Ax⁴ + (B - 2A)x³ + (A + C - 2B)x² + (B - 2C)x + C
By Comparing Coefficients,
A = 1,
B - 2A = -8,
A + C - 2B = 23,
B - 2C = -26,
C = 10
Solving them we get A = 1, B = -6 and C = 10.
Hence x⁴ - 8x³ + 23x² - 26x + 10
= (x - 1)²(x² - 6x + 10).
Using the Quadratic Formula on x² - 6x + 10,
we find that the correct complex roots are
x = 3 + i and x = 3 - i.
Hence,
the zeroes of g(x) are x = 1, x = 3 + i and x = 3 - i.

HELP ME PLEASE !! Last year, Eric biked n miles. This year, he biked 457 miles. Using n , write an expression for the total number of miles he biked.
====================================================
Explanation:
The variable n is a placeholder for a number. Specifically some positive number. Let's say that n = 50. This means Eric biked 50 miles last year.
That would mean in total he biked 50+457 = 507 miles overall over the two years.
Since we don't know what n is, we don't replace it with 50. So we just keep n as it is. We would keep it as n+457
Once, or if, we find out the value of n, then we can replace that letter with that number.
What is the area of this figure? Enter your answer in the box.
Answer:
81 square meters
Step-by-step explanation:
So you can split this figure into one parallelogram (on the bottom) and one triangle (on the top). Find the area of each and then add them together.
The area of a parallelogram is always just length * width, so in this case that would be 9 * 5 = 45 square meters.
Next, the area of a triangle is base * height / 2, so before you can solve you have to find the length of the base.
Going back to the parallelogram, the sides opposite each other are always equal, meaning that if the bottom has a length of 9, the top also has a length of 9.
This means that the top of the parallelogram, which is also the base of the triangle, has a length of 9 m. Now, plug those numbers into the formula for area of a triangle, so:
9 * 8 / 2 = 72 / 2 = 36 square m.
The last step is to add the two areas together:
45 + 36 = 81 square meters.
