Answer:
Graph of Option D represents
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is
Domain of is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of below x axis to obtain the graph of
Answer:
b. Sorted and listed from the minimum to the maximum values
Step-by-step explanation:
A percentile can be defined a measure that is made use of statistics.
A percentile is a statistical measure that indicates or shows comparison amongst a given set of data.
A percentile tells us the value or scores below which a percentage of a given observation in a data set falls.
In other to be able to effectively obtain the percentile if a given set of data, the following steps must be taken.
Step 1: Arrange, sort and list the values of the given the data set in order from lowest to the highest
Step 2: Multiply the percentage (also represented by P ) by total number of values in the data set( also represented by N)
Step 3: The value obtained from step 3 is know as the rank and this would helps us to find the percentile f a given data set.
The formula for calculating a percentiles is given as
= (P/100) x N,
where
P = percentile
N = number of values in a data set (sorted or arranged from lowest to highest)
n = Rank of a given value.

Answer:
(x, y, z) = (-3, -1, 3)
Step-by-step explanation:
Many graphing calculators can solve matrix equations handily. Here, we use a combination of methods.
Use the last equation to write an expression for z.
z = 4 -x +4y
Substitute this into the second equation:
y -4(4 -x +4y) = -13
y -16 +4x -16y = -13
4x -15y -3 = 0
In genera form, the first equation can be written as ...
3x +y +10 = 0
Now, the solution to these two equations can be found to be ...
x = (-15(10) -1(-3))/(4(1) -3(-15)) = (-150 +3)/(4+45) = -3 . . . using "Cramer's rule"
y = -(10 +3x) = -(10 -9) = -1 . . . . from the first equation
z = 4 -(-3) +4(-1) = 3 . . . . . . . . from our equation for z
The solution to the system is (x, y, z) = (-3, -1, 3).
