Step-by-step explanation:
Given:
Total number of students = 20
Number of students who have brown hair = 12
Number of students who have blonde hair = 4
Number of students who have red hair = 3
Number of students who have black hair = 1
To find:
Probability of randomly selecting a blonde-haired student from the classroom.
Solution:
Probability refers to chances of occurring of some event.
Probability = Number of favourable outcomes/ Total number of outcomes
Number of favourable outcomes ( Number of students who have blonde hair ) = 4
Total number of outcomes = 20
So,
Probability of randomly selecting a blonde haired student from the classroom =
Answer:
(x^4) - 64x
Step-by-step explanation:
zeros at 4 and 0 are the roots so can be factor as x*(x-4) and the multiplicity tels to what power you have to raise those factors
becuase multiplicity of 1 for root at 0, and multiplicity of 3 at root 4
now to write this in standard form
Given:
The given system of equations is:
To find:
The solution to this system of equations by graphing.
Solution:
We have,
The table of values for first equation is:
x y
0 1
1 -1
Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.
The table of values for second equation is:
x y
0 -4
2 -3
Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.
The graphs of given equations are shown in the below figure.
From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).
Therefore, the solution to this system of equations is:
x-coordinate: 2
y-coordinate: -3
