Answer:
A
Step-by-step explanation:
The bars are of equal width and correspond to the equal class intervals, while the height of each bar corresponds to the frequency of the class it represents. The histogram is used for variables whose values are numerical and measured on an interval scale.
ok what you need in 3 and 4
We will have a system of equations, and we are going to solve it by using substitution.
Let's make the equations.
x+y+z=2100
z+y=x
Since y and z are equal, I think it is easier for us to have them as one variable for now. Let the value of z and y be a.
These are the equations now.
x+2a=2100
2a=x
Since the second equation is giving the value of x, let it replace the value of x also in the first equation.
2a+2a=2100
4a=2100
2100÷4= 525
so, x and y equal 525. Let's put this in our original equation.
x+525+525=2100
x+ 1,050= 2,100
x= 1,050
So, x=1,050, y= 525 =z.
Answer:
diameter = IJ
radius = KH or IH or JH
chord = LM
length HK = 2
Step-by-step explanation:
if IJ is the diameter and the radius is KH then r must be 2 as the radius is always half the diameter
4^4square root 2 is the answer
