Answer:
>0.95
Step-by-step explanation:
This probably refers to a normal distribution. In a normal distribution, according to the empirical rule,
68% of observed data falls within 1 standard deviation of the mean
95% falls within 2 standard deviations of the mean
99.7% falls within 3 standard deviations of the mean
In this case, the observed data is distance and the average figure for all observed distances is the mean distance.
So, the probability that a/any distance observed exceeds the mean distance by more than 2 standard deviations is >95%
In other words, the probability is >0.95
3. Bob Baffert hos iwo thoroughbred horses in his bom that he brings out
every morning to train for the upcoming rocos. Hoppertunity is a horso
training for a 2.400 meter race and Dortmund is a horse training for an
1,800 meter race. In a given workout, Hoppertunity and Dortmund start
running at the same time. Dortmund runs twice as fast at Hoppertunity:
however, Hoppertunity starts 200 meters ahead of Dortmund. After 12.5
seconds, Dortmund catches up with Hopperlunily.
Letr represent Hoppertunity's rate, Match expressions to the boxes and
symbols to the circles to create an equation that can be used to find the
rate at which Hoppertunity runs. Not all expressions and symbols will be
used, and you may use an expression and/or symbol twice.

Answer:
12.5r + 200 = 12.5*2r
Step-by-step explanation:
GivenRate of Hoppertunity = r
Rate of Dortmund = 2r as it is twice as fast
SolutionLet the distance Hoppertunity runs be d, then the distance Dortmund runs is d + 200 m
Since it took 12.5 seconds Dortmund to catch Hoppertunity, it can be expressed as:
d = 12.5r for Hoppertunity d + 200 =12.5*2r for DortmundBy replacing d in the second equation, we get:
12.5r + 200 = 12.5*2rSoving:
12.5r = 200r = 200/12.5r = 16 m/secHoppertunity's rate is 16 m/sec
Dortmund's rate is 32 m/sec
A city has a population of 12,961. How many people can fit on the football field if the field is
80 yards long and 45 yards wide? Can the population fit? Each person occupies 2.5 square feet
of space.
(3 Points)
Unit Conversion Factors Chart
1 foot
1 inch = 2.54 centimeters
12 inches
1 yard = 3 feet
0.621 miles = 1 kilometer
1 mile = 5,280 feet
1 meter = 100 centimeters
Answer/Step-by-step explanation:
Given:
Population = 12,961
Dimension of field:
length (l) = 80 yards = 80*3 = 240 ft (1 yd = 3 ft)
width (w) = 45 yards = 45*3 = 135 ft
Area of the field = l*w = 240*135 = 32,400 ft²
Area occupied by 1 person = 2.5 ft²
No of people the field can occupy = 32,400 ÷ 2.5 = 12,960
Exactly 12,960 people can fit into the field.
The population of the city, which is 12,961, is more than what the field can accommodate. Therefore, the population cannot fit in.
Write an equation for the nth term of the sequence 4, 12, 36, 108, .
Answer:
26,244
Step-by-step explanation:
First, find the pattern with the numbers you already have. That pattern is × 3.
Since you're already at the fourth term, just keep multiplying your product by 3 until you get to the ninth term.
108 × 3 = 324
324 × 3 = 972
972 × 3 = 2,916
2916 × 3 = 8748
8748 × 3 = 26244
Therefore, your answer is 26,244.

Plot the following points to create a rectangle.
Find the missing vertex.(5.3): (-5,3): (-5.-1) *
Answer:
(5, -1)
Step-by-step explanation:
The three coordinates of a triangle are given as:
(5,3), (-5,3), (-5,-1).
To find:
The missing vertex = ?
Solution:
Let us label the vertices:
A (5,3),
B(-5,3),
C(-5,-1).
Let the missing vertex be ([tex]x, y[/tex]).
Let us recall the properties of a rectangle.
The opposite sides of the rectangle are equal and parallel to each other.
Let us consider the side AB, we can see that only x coordinate is changed from A to B.
Let us consider the side BC, we can see that only y coordinate is changed from B to C.
A and B are adjacent vertices.
Similarly the opposite vertices will be C and D.
Same pattern will be followed in CD as that of AB.
x coordinate will be changed by same difference as that of AB.
Change in x coordinate from D to C = [tex]-5-x[/tex]
Change in x coordinate from A to B = [tex]-5-5 =-10[/tex]
Equating them:
[tex]-5-x=-10\\\Rightarrow x = 5[/tex]
Same pattern is followed in BC and AD.
Their change in y coordinate will be same.
[tex]-1-3=y-3\\\Rightarrow y =-1[/tex]
Missing vertex is (5, -1).
Please refer to the attached image for the rectangle.

Suppose Robert invests $1,200 in the CD for a period of 3 years. How much interest will he earn? How much will Robert have after 3 years?
Answer:
1. The interest is $ 117.
2. The amount is $ 1,317.
Step-by-step explanation:
The following data were obtained from the question:
Principal (P) = $ 1,200
Rate (R) = 3.25%
Time (T) = 3 years
Interest (I) =..?
Amount (A) =...?
1. Determination of the interest.
Principal (P) = $ 1,200
Rate (R) = 3.25%
Time (T) = 3 years
Interest (I) =..?
I = P × R × T / 100
I = 1200 × 3.25 × 3 / 100
I = $ 117
Therefore, the interest is = $ 117
2. Determination of the amount.
This can be obtained as follow:
Interest (I) = $ 117
Principal (P) = $ 1,200
Amount (A) =?
Amount (A) = principal (P) + interest (I)
A = P + I
A = 1200 + 117
A = $ 1,317
Therefore, the amount at the end of 3 years is $ 1,317

Find the corrdinates of the missing endpoint if e is the midpoint of DF F(2’9) e(-1,6)
Answer:
(-4,3)
Step-by-step explanation:
(x1 + 2)/2 = -1
x1 = -4
(y1 + 9)/2 = 6
y1 = 3
So, the other endpoint is (-4,3) .
The missing endpoint is D(-4,3).
What is midpoint of line segment?In geometry, the midpoint of the line segment is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.
Now it is given that,
Midpoint of line segment, e(x,y) = (-1,6)
one endpoint of line segment, F(x₁,y₁) = (2,9)
∴one endpoint of line segment, D(x₂,y₂)
Now since endpoint of line segment is given as,
{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}
Therefore,
x = (x₁+x₂ )/2
y = (y₁+y₂ )/2
Put the values we get,
-1 = (2+x₂)/2
-2 = (2+x₂)
⇒ x₂ = -2 -2
⇒ x₂ = -4
Again,
6 = (9+y₂ )/2
12 = 9+y₂
⇒ y₂ = 12-9
⇒ y₂ = 3
So, the endpoint is (-3,4)
Hence,The missing endpoint is D(-4,3).

Find an equation of the tangent plane to the surface at the point . Question 14 options: a) b) c) d) e)
This question is incomplete, the complete question is;
Find an equation of the tangent plane to the surface z=1y²−1x² at the point (-4, 3, -7).
z = .....................
Note: Your answer should be an expression of x and y; e.g. 3x - 4y + 6.
Answer:
Z = 8x + 6y + 7
Step-by-step explanation:
Given that z = 1y² - 1x²
with points (-4, 3, -7)
so
Z = y² - x²
Equation of tangent plane to the surface Z = f(x,y) at the points ( x₀,y₀,z₀) is
Z - Z₀ = fx (x₀,y₀)(x-x₀) + fy (x₀y₀)(y-y₀)
therefore
Z = f(x,y) = y² - x²
fx = -2x, fx (-4, 3, -7) = -2(-4) = 8
fy = -2y, fy ( -4, 3, -7 ) = 6
Z + 7 = 8(x+4) + 6(y-3)
Z + 7 = 8x + 32 + 6y - 18
Z + 7 = 8x + 32 + 6y - 18
Z + 7 = 8x + 6y + 14
Z = 8x + 6y + 14 - 7
Z = 8x + 6y + 7

Class: Constructing graphs Student Activity Sheet 2; Exploring "Representing data" Date Page 2 of 7 3. What do you notice about the vertical axis used in Graph A? How does this affect the way the data are displayed? FA Graph A 24 The 520 16 Benton population in 1000s 12 2002 2004 2008 2008 2010 Year.
Answer:
Explained below.
Step-by-step explanation:
The vertical axis of Graph A represents the year for which the population of Benton is recorded.
Also the axis represents every other year, i.e. 2002, 2004, 2006 and so on.
This implies that the data is recorded for every other year.
Consider the data provided:
Benton population in 1000s Year
10 2002
11 2004
12 2006
13 2008
14 2010
For every 2 years the population of Benton is increasing by 1000.
That is for every year the population of Benton is increasing by 500.
If we make the vertical axis using the years:
2001, 2002, 2003, 2004, 2005, 2006 and so on, the graph will remain same with more points to plot.
So, on altering the vertical axis the graph does not changes much.

2. 23
3. 69
Step-by-step explanation:
y= 23
check it for your self
Answer:
18, 23 and 69
Step-by-step explanation:
Let x, y and z be the 3 numbers we are looking for.
● x + y + z = 110
z is 3 times y (z = 3y)
● x + y + 3y = 110
x is 5 less than y ( x = y -5)
● y-5 + y + 3y = 110
● 5y -5 = 110
Add 5to both sides
● 5y + 5 -5 = 110+5
● 5y = 115
Divide both sides by 5
● 5y/5 = 115/5
● y = 23
■■■■■■■■■■■■■■■■■■■■■■■■■
we have found that y = 23
● z = 3y
● z = 3×23
● z = 69
● x = y-5
● x = 23-5
● x = 18

Which variable(s) in the data set are measured using a nominal scale? Environment Environment and Age Group Age Group None of the variables
Answer:
Environment
Step-by-step explanation:
Level of measurement used in statistics summarizes what statistical analysis that is possible. We have three types of level of measurement.
Nominal Scale
Ordinal Scale
Interval/ Ratio Scale
The nominal scale known as categorical or qualitative is the most basic level of measurement. Examples include numbers, colour, sex.
Ordinal are variables categorize according to hierarchy they usually have a meaningful order, but the intervals between the variables may not be equal.
In interval/ratio level of measurement, are measured and ordered. Examples are weight or size.
From the given question, it is only the environment that is measured using a nominal scale.
Age group is ordinal because it can be ordered based on hierarchy.
