Answer:
54
Step-by-step explanation:
Angle 2 and Angle 3 are vertical angles
Vertical angles are congruent ( equal to each other )
So if angle 2 = 54 then angle 3 also equals 54
Answer:
∠3 = 54°
Step-by-step explanation:
54° and ∠3 are vertical angles, which means they are equal .
54° = ∠3

Answer:
Mean = 6.66
Median = 7
Mode = 7.68
Step-by-step explanation:
According to the Question,
Given That, the frequency distribution of the score of 40 learners.Class interval frequency
56-63 1
48-55 10
40-47 12
32-39 6
24-31 3
16-23 8
1). Mean = (Sum of all Observation) / (number of observation)
Mean = 40/6 = 6.66
2) For Median, If there are two number in the middle then you need to find their mean. 1 3 6 8 10 12 middle numbers are 6 and 8.
Median = (6+8) / 2 = 7
3) Mode = 3 × Median - 2 × Mean
Mode = 3×7 - 2×6.66
Mode = 7.68
What is a cubic function
Answers
Answer:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.
Alla and Balla together drink 750 milliliters (ml) of water. If Alla drinks 50% more than
Balla, how much does Alla drink?
Answers
Answer:
Step-by-step explanation:
A + B = 750
A = 1.5 B
~~~~~~~~~~~~~~
750-B = 1.5 B
750 = 1.5 B + B
750 = B(1.5 +1)
750 = B (2.5)
B = 300
A = 450

A.Calculate the mean,median and mode.(3 points each) 1.)1,2,3,4,5 2.)2,3,4,5,6,6 3.)6,7,5,4,5,6,2,5
Answers
Answer:
Step-by-step explanation:
1.)1,2,3,4,5
mean=sum of all values/number of values
=1+2+3+4+5/5
=15/5
mean=3
Mode :
In the given data, no observation occurs more than once.
Hence the mode of the observations does not exist, means mode=0.
Median
1,2,3,4,5
Middle value is 3 so the median is 3.
2.)2,3,4,5,6,6
mean=sum of all values/number of values
=2+3+4+5+6+6/6
=26/6
mean =4.33
Mode
is that value of the observation which occurs maximum number of times so here mode is 6.
Median
2,3,4,5,6,6
4+5/2
9/2
median=4.5
3.)6,7,5,4,5,6,2,5
mean=sum of all values/number of values
=6+7+5+4+5+6+2+5/8
=40/8
mean =5
Mode
is that value of the observation which occurs maximum number of times so here mode is 5
Median
2,4,5,5,5,6,6,7
5+5/2
10/2
median=5
Layers of rock wear off during which of the following processes?
A: Expansion B: Contraction C: Exfoliation D: Pressure
Answers
Answer:
Exfoliation
Step-by-step explanation:
Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day to night. Eventually, outer layers flake off in thin sheets, a process called exfoliation.
The system of equations Y equals -1/5 X -6 and Y equals negative 2X +3 is shown on the graph below
Answers
Answer:
The solution of the system is (5, -7)
Step-by-step explanation:
Here we have the system:
y = (-1/5)*x - 6
y = -2*x + 3
We know that this system is graphed below, and the question is incomplete, but I assume that we want to find the solution to this system. If you can see the graph, the solution is just the point where both graphs intersect, but we can find the solution analytically.
We know that:
y = (-1/5)*x - 6
y = -2*x + 3
Then, we can write:
y = (-1/5)*x - 6 = y = -2*x + 3
This leads to:
(-1/5)*x - 6 = -2*x + 3
Now we can solve this for x.
(-1/5)*x + 2*x = 3 + 6
(-1/5)*x + (10/5)*x = 9
(9/5)*x = 9
x = (5/9)*9 = 5
x = 5
now that we know the value of x, we can input this in one of the two equations above to find the correspondent value of y, we will get:
y = -2*x + 3 = -2*5 + 3
y = -10 + 3 = -7
y = -7
Then the solution is:
x = 5 and y = -7, or (5, -7)

Given:
A quadrilateral DEFG inscribed in a circle.

To find:
The value of variables [tex]m[/tex] and [tex]k[/tex].
Solution:
If a quadrilateral is inscribed in a circle then it is a cyclic quadrilateral. The opposite angles of a cyclic quadrilateral angle supplementary angles.
Quadrilateral DEFG inscribed in a circle. So, quadrilateral DEFG is a cyclic quadrilateral.
[tex]m\angle D+m\angle F=180^\circ[/tex] [Supplementary angle]
[tex]60^\circ+2k^\circ=180^\circ[/tex]
[tex]2k^\circ=180^\circ-60^\circ[/tex]
[tex]2k^\circ=120^\circ[/tex]
Divide both sides by 2.
[tex]k^\circ=\dfrac{120^\circ}{2}[/tex]
[tex]k^\circ=60^\circ[/tex]
[tex]k=60[/tex]
Similarly,
[tex]m\angle E+m\angle G=180^\circ[/tex]
[tex]m^\circ+60^\circ=180^\circ[/tex]
[tex]m^\circ=180^\circ-60^\circ[/tex]
[tex]m^\circ=120^\circ[/tex]
[tex]m=120[/tex]
Therefore, the values of the variables are [tex]m=120[/tex] and [tex]k=60[/tex].

What is a set ?A set is collection of well defined objects.
According to the given question we have to state whether A ∪ ( B - C ) = ( A ∪ B ) - C.
Lets consider we have three sets A, B and C and we also consider they intersect each other.
( B - C ) represents the elements which belongs to B but not in C.
∴ A ∪ ( B - C ) represents the no. of elements which belongs to the set B but not in C union the no. of elements which belongs to A.

Quadrilateral ARMY is rotated 90 degrees about the origin. Draw the image of this rotation.
Answers
Answer:
Step-by-step explanation:
If a point (x, y) is rotated 90° counterclockwise about the origin, rule for the rotation will be,
(x, y) → (-y, x)
Therefore, coordinates of the image point after the rotation will be (-y, x).
Following this rule,
Image points of the quadrilateral will be,
A(3, 3) → A'(-3, 3)
R(5, 7) → R'(-7, 5)
M(7, 5) → M'(-5, 7)
Y(5, 1) → Y'(-1, 5)
By graphing the image points we can get the graph of the image quadrilateral A'R'M'Y'.
