Answer:
<u>The slope-intercept form </u>
Here m is the slope and b is y-intercept
<u>When b= 0</u>
and
In this case Avery's method works
<u>When b≠0</u>
In this case Avery's method brings wrong outcome
Let
x--------> the amount of gummy candy in pounds
y--------> the amount of jelly beans in pounds
z--------> the amount of hard candy in pounds
we know that
--------> equation
--------> equation
--------> equation
Substitute equation in equation and equation
-----> ------> equation
-----> ------> equation
using a graphing tool ------> Solve the system of equations
see the attached figure
the solution is the point
<u>Find the value of x</u>
therefore
<u>the answer is</u>
the amount of gummy candy is
the amount of jelly beans is
the amount of hard candy is
the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.

Answer:
a) A. The population must be normally distributed
b) P(X < 68.2) = 0.7967
c) P(X ≥ 65.6) = 0.3745
Step-by-step explanation:
a) The population is normally distributed having a mean () = 64 and a standard deviation () =
b) P(X < 68.2)
First me need to calculate the z score (z). This is given by the equation:
but μ=64 and σ=19 and n=14, and
Therefore:
From z table, P(X < 68.2) = P(z < 0.83) = 0.7967
P(X < 68.2) = 0.7967
c) P(X ≥ 65.6)
First me need to calculate the z score (z). This is given by the equation:
Therefore:
From z table, P(X ≥ 65.6) = P(z ≥ 0.32) = 1 - P(z < 0.32) = 1 - 0.6255 = 0.3745
P(X ≥ 65.6) = 0.3745
P(X < 68.2) = 0.7967
