The histogram showing the number of events with the events cost is
misleading because;
- The x-axis scale shows the data is more clustered than it actually is
<h3>How can the histogram be analyzed?</h3>
Please find attached a possible diagram of the histogram in the question
created with MS Excel;
The data in the histogram is presented as follows;
From the above table, we have that the class with event cost of 2000 to
2499 is left out, therefore, the data is more clustered.
The correct option is therefore;
<u>The x-axis scale shows the data is more clustered than it actually is</u>

Answer:
Part 1) The measure of the exterior angle is 128°
Part 2) The measure of angle x is 30°
part 3) The value of x is 25 units
Step-by-step explanation:
Part 1)
step 1
Find the measure of the third internal angle of the triangle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
Let
c----> the measure of the third internal angle
42+(9x-4)°+c°=180°
c=180°-42°-9x+4°
c=142°-9x
step 2
Find the value of x
we know that
c+(12x+8)°=180° ----> by supplementary angles
substitute
142°-9x+(12x+8)°=180°
3x=30°
x=10°
step 3
Find the measure of the exterior angle
(12x+8)°=(12(10)+8)°=128°
Part 2) Find the value of x
The figure show a equilateral triangle ( has three equal internal angles and three equal sides) and an isosceles triangle ( has two equal internal angles and two equal sides)
Remember that
The internal angles of a equilateral triangle is 60 degrees
so
The vertex angle of the isosceles triangle is equal to
180°-60°=120° ----> by supplementary angles
therefore
The base angle of the isosceles triangle is equal to
2x+120°=180°
2x=60°
x=30°
Part 3) we know that
if AB is a midsegment
then
(4x-10)/2=45
solve for x
4x-10=90
4x=100
x=25 units
Yeah you did well on the table
Answer:
Given coordinetes of triangle A(−2,3),B(8,3) and C(6,7)
AB=
[8−(−2)]
2
+(3−3)
2
=
(10)
2
+(0)
2
=
100
AC=
[6−(−2)]
2
+(7−3)
2
=
(8)
2
+(4)
2
=
64+16
=
80
BC=
(6−8)+[7−(2)]
2
=
(−2)
2
+(4)
2
=
4+16
=
20
If ABC is a right angled triangle, then square of one side must be equal to sum of suare of other two sides.
AB
2
=(
100
)
2
=100
and AC
2
+BC
2
=(
80
)
2
+(
20
)
2
=100
∴AB
2
=AC
2
+BC
2
thus triangle satisfies the Pythagoras theorem
Hence, the triangle is right angled triangle.
