Vertex
we have
f(x)=x²-18x+88
let
y=x²-18x+88
comparing above equation with ax²+bx+c
we get
a=1
b=-18
c=88
now
vertex(x,y)=(-b/2a,f(-b/2a))
x=(18/2×1)=9
y=f(9)=9²-18×9+88=7
SO
VERTEX(X,Y)=(9,7)

1. Construct two box plots, one for the data in each group.
2. Which group shows greater variability? Explain how you know.
Answers
Answer:
Group A has greater variability
Step-by-step explanation:
Group A: 80, 100, 190, 110, 70, 90, 130
The variability of group A data :
Taking the range :
Maximum = 190 ; Minimum = 70
Range = Maximum - Minimum ; 190 - 70 = 120
Group B : 50, 110, 100, 120, 107, 140, 150
The variability of group B data :
Taking the range :
Maximum = 150 ; Minimum = 50
Range = Maximum - Minimum ; 150 - 50 = 100
Hence, Group A has greater variability
Here is the histogram of a data distribution.
What is the shape of this distribution?
A. Bimodal symmetric
B. Uniform
c. Unimodal symmetric
D. Bimodal skewed
E. Unimodal skewed
Answers
Answer:
Uniform
Step-by-step explanation:
We don't have any peaks in the histogram, so its neither unimodal or bimodal leaving only uniform as the answer.
The shape of this distribution, histogram is Unimodal skewed type. The correct option is E.
What is histogram?A histogram represents the graphical representation of the distribution of data. The histogram is indicated by using a set of rectangles adjacent to each other where each bar represent a kind of data. The histogram doesn't involve any gaps between the two successive bars.
The histogram would be classified into different types based on the frequency distribution of the data.
Based on the direction of the tail, the skewed distribution may be either right-skewed or left skewed.
Since skewed distribution is asymmetrical as a limit which is natural resists end results on one side.
Threfore, the correct option is E.

What is the slope of a line parallel to the line whose equation is 15x+9y=-16215x+9y=−162. Fully simplify your answer.
Answers
Answer:
-5/3
Step-by-step explanation:
Any line parallel to the given line will have the same slope as the given equation;
Given the equation 15x+9y=-162
Rewrite in standard from y = mx+b
15x+9y=-162
9y = -15x - 162
y = -15/9 x - 162/9
y = -5/3 x - 18
This gives the required equation;
Since mx = -5/3 x
m = -5/3
Hence the slope of the line parallel to the given line is -5/3

Absolute value of -8 = 8
Find the absolute values of the other numbers
The other numbers have to be less than 8 or else they are less than -8
Absolute value of 2.6 = 2.6 . 2.6<8
Absolute value of -10 = 10 . 10 >8 . not correct
Absolute value of -2 = 2 . 2<8
Absolute value of 4 = 4 . 4<8
Absolute value of 1/4 = 1/4 . 1/4<8
Absolute value of -8.5 = 8.5 . 8.5>8 . not correct
About Absolute Value:
Absolute value is the distance from 0 on the number line.
The number 5 is 5 units from 0
The number -5 is also 5 units from the 0, except from the opposite side
Absolute value states that negative numbers have a positive absolute value and a positive number has a positive absolute value.

A cylinder has a base radius of 3m and a height of 17m. What is its volume in cubic m, to the nearest tenths place?
Answers
Answer:
V= 480.7 m cubed
The volume of the cylinder nearest to tenths place is 480 m^3.
What is cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface.
For the given situation,
The formula for volume of the cylinder is [tex]V=\pi r^{2} h[/tex]
Radius of the cylinder,r = 3 m
Height of the cylinder, h = 17 m
The value of π = 3.14
On substituting the above values,
[tex]V=(3.14) (3^{2})(17)[/tex]
⇒ [tex]V=480.42[/tex] ≈ 480
Hence we can conclude that the volume of the cylinder is 480 m^3.

A right square pyramid has a slant height of 25 feet, and the length of a side of the base is 14 feet. What is the height of the pyramid?
Answers
Answer: [tex]24\ ft[/tex]
Step-by-step explanation:
Given
The slant height of the square pyramid is [tex]l=25\ ft[/tex]
The length of the side of the base is [tex]a=14\ ft[/tex]
for the square pyramid, height is given by
[tex]\Rightarrow h=\sqrt{l^2-r^2}\quad \quad [\text{where r=}\frac{a}{2}]\\\Rightarrow h=\sqrt{25^2-7^2}\\\Rightarrow h=\sqrt{625-49}\\\Rightarrow h=\sqrt{576}\\\Rightarrow h=24\ ft[/tex]
Thus, the height of the prism is [tex]24\ ft[/tex]
