Answer:


Step-by-step explanation:
Let the salted package be represented with 1 and the unsalted, 2.
So:
Mean of salted package
Mean of unsalted package
Considering the given options, the null hypothesis is that which contains =.
So, the null hypothesis is:

The opposite of = is
. So, the alternate hypothesis, is that which contains 
So, the alternate hypothesis is:

Let Ricky = x; so equation: x + (x+283) = 2675 ; Re-arrange so x = Ricky = 1196 hits with Pedro 1196 + 283 = 1479.
Answer: 4x² + x - 2
Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²
Now let's work on the second part:
Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals
12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:
4x² + x - 2.

The point-slope formula states:
(

=
m
(
x

)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope and values from the point in the problem gives:
(
y

If you want the equation in the somewhat more familiar slope-intercept form we can solve this equation for
y
. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.
