The probability the next person surveyed is very prepared is 0.119.
What actually does probability mean?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number ranging from zero and 1, where, roughly, 0 denotes the event's impossibility and 1 represents certainty.Formula of total frequency is,
Total = f₁ + f₂ + f₃ + f₄ +...............n∑fi
The total frequency is,
total = n∑i=2 fi ⇒ 262 + 992 + 587 + 313 + 52
The total number of people prepared for a long-term power outage, natural disaster, or terrorist attack is obtained by taking the sum of the all frequencies.
probability = N(E)/N(S)
the information given, there are 262 people are very prepared.
That is, N(A) = 262
The required probability is,
P(A) = 262/2206
= 0.119

45. Write an inequality that represents the graph. Explain it step by step please.
Answer: x < -4
Step-by-step explanation:
➜ First thing we notice is the open circle. This means we will use either < or >
➜ The next thing we notice is that the values are pointing to the left of the circle, this means we will be using <
➜ The last part we notice is that the dot is on -4. This is the value we'll use to write our inequtliy.
The last thing to do is to write the inequality using the parts we pointed out above:

What is the length of a rope if the mass of a rope is 4.25
Using a regression calculator, the line of best fit for the given set of data is:
[tex]y=0.34121x+0.168088[/tex]where y = mass of the rope and x = length of the rope.
To estimate the length of the rope if its mass is 4.25 kilograms, let's replace "y" in the equation above with 4.25, and then solve for x.
[tex]4.25=0.34121x+0.168088[/tex]Subtract 0.168088 on both sides of the equation.
[tex]4.25-0.168088=0.34121x+0.168088-0.168088[/tex][tex]4.081912=0.34121x[/tex]Then, divide both sides of the equation by 0.34121.
[tex]\frac{4.081912}{0.34121}=\frac{0.34121x}{0.34121}[/tex][tex]\begin{gathered} 11.963049=x \\ 11.96\approx x \end{gathered}[/tex]Therefore, the length of the rope having a mass of 4.25 kilograms is approximately 11.96 meters.

Predict the amount of tips that would be collected if 100 customers were served at the restaurant on a given day Explain your reasoning. Answer is $178 explain your answer thank you! 40 points if answered correctly!!
Answer:
$194.69
Step-by-step explanation:
The best way to predict the amount of tips is using this formula:
[tex]100(\frac{Tips(total)}{Customers(total)} )[/tex]
This finds the average tip per customer with all of the data, and multiplies it by 100 to get the predicted amount of tips for 100 customers.
Plugging in the data from the table gives you this equation:
[tex]100(\frac{1174}{603} )[/tex]
This equals $194.69.
Write the equation of the perpendicular bisector of XY if endpoint X is at (-9,1) and endpoint Y is at (3,5). A) y = -X B) y = 3x - 6 C) y = -3x - 6 D) y = 3x + 12
A perpendicular bisector is a segment which intersects another segment on its midpoint and with a right angle.
First, we have to find the midpoint between X(-9,1) and Y(3,5), as follows
[tex]\begin{gathered} M=(\frac{-9+3}{2},\frac{1+5}{2}) \\ M=(\frac{-6}{2},\frac{6}{2}) \\ M=(-3,3) \end{gathered}[/tex]This means the perpendicular bisector must pass through (-3,3). Now, with the given points we find the slope of XY
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{5-1}{3-(-9)}=\frac{4}{3+9}=\frac{4}{12} \\ m=\frac{1}{3} \end{gathered}[/tex]Then, we apply the rule of perpendicularity to find the slope of the perpendicular bisector.
[tex]\begin{gathered} m_1\cdot m=-1 \\ m_1=\frac{-1}{m} \\ m_1=-\frac{1}{\frac{1}{3}}=-3 \end{gathered}[/tex]Now, we use the slope-point formula to find the equation for the perpendicular bisector.
[tex]y-y_1=m(x-x_1)[/tex]Where we replace the slope -3 and the point (-3,3).
[tex]\begin{gathered} y-3=-3(x-(-3)) \\ y-3=-3x-9 \\ y=-3x-9+3 \\ y=-3x-6 \end{gathered}[/tex]Therefore, the right answer is C.vinny has decided to order high tops in black and white at a 5.8 ratio. he beleives he will need a total of 169 pairs. how many black high tops will he order

Answer:
the probability is 2/8
Step-by-step explanation:
From the diagram below, if the sides AD = 3 and DC = 27, and BD = X + 3, find x.
Given:
• AD = 3
,• DC = 27

Let's solve for x.
To solve for x, apply the altitude formula:
[tex]\frac{AD}{BD}=\frac{BD}{DC}[/tex]Where BD is the altitude.
Cross multiply:
[tex]BD^2=AD*DC[/tex]Plug in the values and solve for x:

What is termed as the pentagon?A pentagon is a two-dimensional polygon with 5 sides and 5 angles.This shape should have five sides and form a closed two-dimensional figure. A closed figure consists of each of its sides intersecting to form vertices.Five diagonals connect the five vertices to one‘s opposite vertices in a pentagon shape.Each interior angle in a regular pentagon is 108°, so each exterior angle is 72°.For the given question;
The exterior angles of the pentagon are given in figure.
Find all the interior angles for given angles using linear pair as all are straight lines.

Equation for the line in point-slope form is 5x + 6y = 6.
What is point slope form?The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form.
Given Data
P(6, -3)
y =1/2 x + 2
When the equation has been solved for y, the line in slope intercept form with slope = m = 1/2 = the coefficient of the x term is represented by the equation y= (1/2)x + 2. 2 represents the y coordinate of the location (0, 2) where the line intersects the y axis as the y intercept.
So, the points are (6,-3) and (0,2)
Formula
y₂ - y₁ = m(x₂ - x₁)
slope of the line (m) = [tex]\frac{x-x}{y-y}[/tex]₁¹
m= [tex]\frac{2-(-3)}{0-6}[/tex]
m = -[tex]\frac{5}{6}[/tex]
