C is the correct answer my love lmk if it’s correct
Answer:
the height of the water in the pool is 2m
Step-by-step explanation:
This problem bothers on the mensuration of solids.
Given data
Volume of pool v= 270m³
Base length l= 15m
Base width b= 9m
Height h=?
The pool takes the shape of a rectangular prism
The expression for the volume of the pool is
v= l*b*h
Substituting our given data we have
270= 15*9*h
270= 135h
h= 270/135
h= 2
Therefore the height h =2m
Answer:
B. y = |2x| - 2.
Step-by-step explanation:
If we start with y = 2x:
this passes through the origin and has a slope of 2.
y = |2x| means the absolute ( positive) values only, so the part of the line below the x axis is reflected in the axis to form a V shaped graph.
So we have a V shaped graph with the vertex at (0, 0).
Then -2 brings the vertex from (0, 0) to (0 -2) so we get:
y = |2x| - 2.

Just did this assignment.
The probability distribution of normal distribution is given by,
f(x) =

Where a = mean = 16 and α = standard deviation = 3
In normal distribution, skewness is zero. That is, distribution is symmetric.
Therefore, mean, median and mode coincide at a point in case of normal distribution.
50th percentile is same as median or mean or mode
Therefore, 50th percentile = 16
