Answer:
Second Data Set
Step-by-step explanation:
The mean absolute deviation describes the average distance between each data point. Let's consider both data sets. In data set one, classmate ages are recorded. Because most of Jordan's classmates are close together in age, the amount of deviation is small. In data set two, teach ages are recorded. Because teacher's ages can range from 23-99, the deviation in this set is expected to be larger than set one.
When a system of two linear equations has no solution, how do the graphs of the equations appear?
Answer:
parallel lines that never intersect.
Step-by-step explanation:
When dealing with two linear equations that have no solution, it means that they usually have two variables and are part of a system of equations. Such an example would be the following two equations
2x - y = 2
4x - 2y = 8
These two equations would be part of the same system and they have no solution because there is no pair of values that will give a valid solution to both for the variables x and y. In a graph these equations would appear as parallel lines that never intersect. This is why no solution is found, because there is no intersection.

Algebraically, find the roots of x² - 4x - 5=0,
which set of ordered pairs could be generated by an exponential function
Answer:
Option C represents an exponential function
Step-by-step explanation:
Generally, we have an exponential function in the form ;
y = a.b^x
Where in fact, a is not 0
In this case, let us have a as 1 and b as 2
So we have;
for x = -1
y = 2^-1 = 1/2
for x = 0
y = 2^0 = 1
for x = 1
y = 2^1 = 2
for x = 2
y = 2^2 = 4
So the correct choice here is the third option

Camila is working two summer jobs, making $10 per hour lifeguarding and $6 per hour walking dogs. Last week Camila worked 5 more hours lifeguarding than hours walking dogs and earned a total of $114. Write a system of equations that could be used to determine the number of hours Camila worked lifeguarding last week and the number of hours she worked walking dogs last week. Define the variables that you use to write the system.
Let L = the numbers of hours lifeguarding
Let D = the number of hours walking dogs
Camila makes $10 per hour lifeguarding, so in L hours she will make 10L dollars. Camila makes $6 per hour walking dogs, so in D hours she will make 6D dollars. The total amount earned 10L+6D equals $114.
Since Camila worked 5 more hours lifeguarding than hours walking dogs, she worked more hours lifeguarding, so if we add 5 to the number of hours walking dogs, we will get the number of hours lifeguarding, meaning L equals D+5.
10L+6D=114
L=D+5

1. A tourist sights the Hancock tower from the highway with an angle of elevation of 12°. If the
Hancock tower is known to be 1350 feet high, how far away is the tourist, to the nearest tenth?
Answer: [tex]6351.25\ ft[/tex]
Step-by-step explanation:
Given
Angle of elevation [tex]x=12^{\circ}[/tex]
Height of tower [tex]h=1350\ ft[/tex]
Suppose tourist is d feet away from the tower
from the figure, we can write
[tex]\Rightarrow \tan 12^{\circ}=\dfrac{1350}{d}\\\\\Rightarrow d=\dfrac{1350}{\tan 12^{\circ}}=6351.25\ ft[/tex]
Thus, the distance of tourist from the tower is [tex]6350.25\ ft[/tex]

WILL REWARD BRAINIEST! A right rectangular container is 6 cm wide and 10 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 1.7 cm. Find the volume of the stone.
Answer:
102cm^3
Step-by-step explanation:
v=l×w×h
10x6x7=420 cm^3
the volume of water+stone=
10×6×(7+1.7)
522cm^3
522-420= 102cm^3
The solution is: the volume of the stone is : 102cm^3.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
Here, we have,
Given that,
A right rectangular container is 6 cm wide and 10 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 1.7 cm.
We know that,
volume is :
v=l×w×h
so, we get,
10x6x7=420 cm^3
the volume of water+stone=
10×6×(7+1.7)
522cm^3
522-420= 102cm^3.
Hence, The solution is: the volume of the stone is : 102cm^3.

Step-by-step explanation:
Substitute each given value of the variable to find which, if any, is a solution of inequality.
Given:
The inequalities are:
a) [tex]w<-8, w=-4.3, -5.3, -8.3, -9[/tex]
b) [tex]t>-25, t=-24, -25, -25.1, -27[/tex]
To find:
The solution of inequalities by substituting the given values.
Solution:
a) We have,
[tex]w<-8, w=-4.3, -5.3, -8.3, -9[/tex]
After substituting the given values one by one, we get
[tex]-4.3<-8[/tex] False statement.
[tex]-5.3<-8[/tex] False statement.
[tex]-8.3<-8[/tex] True statement.
[tex]-9<-8[/tex] True statement.

Step-by-step explanation:
An angle measures 56° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
118, 62
Step-by-step explanation:
We can set a system of equations where x and y are the two angles and x is the larger one
x+y=180
x-y=56
If we subtract the second equation from the first, we get 2y=124, simplifying that, we get y=62. Plugging it into either equation, we get x=118. We can check that 118 is 56 larger than 62, which it is. Thus, x=118, y=62.

Hello, I Am BrotherEye
Answer: Here is an Example On How To Solve Your Problem.
Step-by-step explanation:
Explanation:

The minimum is the lowest number in the data set.
Since it is listed from smallest to largest, we know that the minimum is
29
.
The median is the middle number. Cancel out
3
numbers from each side and we are left with the median:
29
,
33
,
36
,
37
,
39
,
40
,
41
Therefore, the median is
37
.
The first quartile (Q1) is the median of the lower half of data which lies at 25% of the data.
Let's look at the lower half of numbers:
29
,
33
,
36
The number in the middle is
33
, so that is the first quartile.
The third quartile (Q3) is the median of the upper half of data which lies at 75% of the data.
Let's look at the upper half of numbers:
39
,
40
,
41
The number in the middle is
40
, so that is the third quartile.
The maximum is the highest number in the data set; it is
41
.
So here's the five-number summary:
Minimum: 29
First quartile: 33
Median: 37
Third quartile: 40
Maximum: 41
If the base of a Pyramid has an area of 144sq ft And if the slant higher of the pyramid is 10ft what would be the higher of the pyramid
Answer:
the height of the pyramid is 8 ft
Step-by-step explanation:
Considering the base of the pyramid to be square whose area is 144 sq ft
This means the side of the base would be √144 = 12 ft.
Now, if you will imagine a pyramid we can easily observe that
Height(H) , slant height( L=10 ft) and half of the side length( 6ft) make a right angle triangle. We can easily calculate height from Pythagoras theorem as
10^2 = H^2 +6^2
⇒ H^2 = 10^2-6^2 = 100-36 = 64
⇒ H = 8 ft
Therefore, the height of the pyramid is 8 ft
