Which of the following is true of an outlier?
An outlier is a false data point.
An outlier does not affect measures of central tendency.
An outlier is not near the main cluster of data.
An outlier is always the highest or lowest value in a data set.
Answers
An outlier is a data point that is significantly different from the other data points in a set. It may or may not affect measures of central tendency. Outliers are not always the highest or lowest values in a data set.
Explanation:An outlier is a data point that is significantly different from the other data points in a set. It can be either higher or lower than the other values.
Outliers may be errors or abnormal data, or they may provide valuable insights into the population under study.
An outlier does not necessarily mean that it is a false data point. It needs to be examined closely to determine if it should be included in the analysis or not.
An outlier may or may not affect measures of central tendency, such as the mean, median, and mode.
It depends on the specific data set and the impact of the outlier on these measures. It is not always the highest or lowest value in a data set, as it can be any data point that deviates significantly from the rest.

Mr. haigwood is shopping for a school picnic . veggie burgers comes in packages of 15 and buns come in packages of 6. he wants to serve veggie burgers on buns and wants to have no items left over. Mr. haighwood says that he will have to buy at least 90 of each item 6 x 15 =90. Do you agree with his reasoning
Answers
LCM = 30,
so they need to buy atleast 30 of each item.
Answer:
Mr. haigwood is not right.
Step-by-step explanation:
The veggie burgers comes in packages of 15 and buns come in packages of 6.
Mr. haigwood wants to serve veggie burgers on buns and wants to have no items left over.
Now, to find the least number of burgers and buns needed so nothing is left over, we will find the LCM of 15 and 6.
15 = 3 x 5
6 = 2 x 3
LCM = 2 x 3 x 5 = 30
As given, Mr. haighwood says that he will have to buy at least 90 of each item 6 x 15 =90.
This is not right. He needs to buy at least 30 of each item so that nothing is left over.
A 12 foot ladder is placed 4 feet away from a house as shown. What is the value of x, rounded to the nearest degree ?
Answers
cos(x) = adjacent/hypotenuse = 4/12 ≈ 0.3333 ⇒ x ≈ 71°
#2
71° is between 70° and 75°, so the answer is yes, the ladder being used safely.
x = 71 degrees. Yes, the ladder meets safety standards.
What is Hypotenuse?A hypotenuse is defined as the longest side of a right triangle, the side opposite the right angle where the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of is the square of the lengths of the other two sides.
The equation is expressed as:
[tex]a^2 + b^2 = c^2[/tex]
a = side of right triangle
b = side of right triangle
c = hypotenuse
For above given information, the problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x".
For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 /12= 1/3
x is approximately 70.52° which is 71° rounded to the nearest degree.
Thus, x = 71 degrees. Yes, the ladder meets safety standards.

Find the equation of the circle in standard form for the given center (h,k) and radius r: (h,k)=(0,0), r=9
Answers
Answer: [tex]x^2+y^2=81[/tex]
Step-by-step explanation:
The equation of circle ( in general form ) is given by :_
[tex](x-h)^2+(y-k)^2=r^2[/tex]
, where r= radius of the circle .
(h,k) = center of the circle .
Given : Center = (h,k)= (0,0)
Radius = r = 9 units
Then the equation of the circle will be :-
[tex](x-0)^2+(y-0)^2=(9)^2[/tex]
[tex]\Rightarrow x^2+y^2=81[/tex]
Hence, the required equation of the circle = [tex]x^2+y^2=81[/tex]

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F.
F = 9 over 5C + 32
Which of the following formulas correctly solves for C?
C = 5F - 32 over 9
C = 5 F over 9 - 32
C = 9 over 5(F – 32)
C = 5 over 9(F – 32)
Answers
F - 32 = 9/5C...multiply both sides by 5/9, eliminating the 9/5 on right
5/9(F - 32) = C <==
Answer:
C = 5 over 9(F – 32)
Step-by-step explanation:
The formula is [tex]F=(\frac{9}{5}C)+32[/tex]
We can do some algebra to solve for C (note the steps below):
[tex]F=(\frac{9}{5}C)+32\\F=(\frac{9C}{5})+32\\F-32=\frac{9}{5}C\\C=\frac{F-32}{\frac{9}{5}}\\C=\frac{5}{9}(F-32)[/tex]

Y=x3, vertically stretch by a factor of 4. How would the final equation look like?
Answers
a vertical stretch means that if (a, b) is in the original function, the second function will contain the point:
(a, 4b)
For example: (2, 8) is in the graph of the original function.
If the graph of the function is stretched vertically by a factor of 4, this means that (2, 8) becomes (2, 8*4)=(2, 32)
So to describe this stretch, the equation must be [tex]y=4x^3[/tex]
Answer: [tex]y=4x^3[/tex]
Vertically stretching the equation[tex]Y=x^3[/tex] by a factor of 4 results in the equation [tex]Y=4x^3[/tex]. This means that the value of the function increases four times for every x. Visually, the stretched function appears steeper along the y-axis.
Explanation:The equation represents[tex]Y=x^3[/tex] a cubic function. When you vertically stretch a function by a factor of 4, this means you multiply the output (Y-values) of the function by 4. Therefore, to vertically stretch Y=x3 by a factor of 4, you will multiply the entire function by 4. The final equation would look like [tex]Y=4x^3[/tex]
To clarify, the 'stretch' implies that for each x, the value of the function increases four times. This change can is noticeable graphically as the function will look 'steeper' or 'more stretched out' along the y-axis.

Vector u has its initial point at (14, -6) and its terminal point at (-4, 7). Write the component form of u and find its magnitude.
Answers

The component form of vector u is (-18, 13) and its magnitude is approximately 22.2.
Explanation:The subject of this question is vector algebra, specifically finding the component form and magnitude of a vector. The component form of a vector is found by subtracting the coordinates of the initial point from the terminal point. Thus, the component form of vector u with initial point at (14, -6) and terminal point at (-4, 7) is (-4-14 , 7-(-6)) = (-18, 13).
To find the magnitude of a vector, you use the formula which is the square root of the sum of the squares of the components. So for vector u, the magnitude is found by calculating √((-18)² + 13²) = √ (324 + 169) = √493, which is approximately 22.2.

To find the probability of getting a blue jelly bean, we use the equation P = B / Total. Substituting the given values, we find that the probability of getting a blue jelly bean is approximately 0.1733 or 17.33%.
Explanation:To solve the given problem, we can use the equation provided in the example: P = B / 26. Since we know that there are 26 blue jelly beans out of 150 total jelly beans, we can substitute these values into the equation to find the probability: P(B) = 26 / 150. Simplifying this fraction, we get P(B) = 13 / 75.
Therefore, the probability of getting a blue jelly bean is 13/75, or approximately 0.1733, which can be expressed as a percentage as 17.33%.

Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-2j' to each side of the equation.
j + -2j = 3 + 2j + -2j
Combine like terms: j + -2j = -1j
-1j = 3 + 2j + -2j
Combine like terms: 2j + -2j = 0
-1j = 3 + 0
-1j = 3
