Answer:
28%
Step-by-step explanation:
So I am assuming the numbers are the number of students.
So 64 + 28+ 52 +56 = 200 students
Assuming the 56 outside the diagram are NOT attending either college.
so 56/200 =28%
Slope of a line = (y2-y1)/(x2-x1)
In this problem:
y2= 1
y1= 0
x2=4
x1= 3
m = (y2-y1)/(x2-x1)
m = (1-0)/(4-3)= 1/1= 1
y= mx+b (line equation)
y-intercept occurs when x=0. So, plug in a point to find b.
I used (4,1)
y=mx+b
y= (1)x+b
1=(1)(4)+b
1=4+b
b= -3
Y-intercepts of the x-axis at (0,-3). Y-intercept= -3
Any further questions?
Answer:
3888pi cm^3 or 12214.5122372 cm^3
Step-by-step explanation:
To being, let's list out what we know
The volume of a sphere is
V = 4/3(pir^3)
But this is only half of a sphere, so the volume of it should be
V =2/3(pir^3)
With the diameter of the shape being
d = 36
We will first need to find the radius to use the formula above
r = d / 2
= 36 / 2
= 18
Now, let's start plugging in values
V = 2/3(pi18^3)
= 2/3 ( 5832pi)
= 3888pi or 12214.5122372

Answer C
Answer:
x=9, y =-8-z, w =1, z=z
Step-by-step explanation:
Given that the augmented matrix in row-reduced form below is equivalent to the augmented matrix of a system of linear equations.
[ 1 0 0 0 | -9 ]
[ 0 1 1 0 | -8 ]
[ 0 0 0 1 | 1 ]
We find that this is a rectangular matrix 3 rows and 4 columns
i.e. the variarables are four but independent equations are only 3.
so only parametric equations can be found out
First row gives x = -9
Last row gives w = 1
II row gives y+z =-8 and we do not have any other equation in y or z
Hence we have solutoin as
z =z and y -8-z
The solution set is
x=9, y =-8-z, w =1, z=z
