See below for the response to each question
<h3>The variable</h3>
This is the item that is being surveyed.
The surveyed item is birth weights
Hence, the variable is birth weights
<h3>The
units of the variable</h3>
From the question, we have:
Average birth weight is 6 pounds 8 ounces.
Hence, the units of the variable are pounds and ounces
<h3>The population</h3>
This is the total number of babies in Southeast Asia
Hence, the population of interest is the babies in Southeast Asia
<h3>The individual</h3>
This is the people in the survey
Hence, the individual in the study is the 100 babies that were randomly surveyed
<h3>The
parameter of interest</h3>
This is the value that gives the required information.
Hence, the parameter of interest is the average birth weight
<h3>What is the statistic involved</h3>
The statistic is the average

No solutions- equations never intersect (parallel lines)
Explanation:
First, let's convert our second equation into slope-intercept form
y
=
m
x
+
b
Let's subtract
2
x
from both sides to get
−
y
=
−
2
x
+
2
Next, divide all terms by
−
1
to get
y
=
2
x
−
2
We see that our slope, the coefficient on the
x
term, is
2
. This equation has the same slope as the first.
It is important to realize that when two lines have the same slope, it means they are parallel. This means they never intersect.
Since they never intersect, it means this system has no solution.
Hope this helps!
Answer:
y = (√7)/4
Step-by-step explanation:
The equation of the unit circle is ...
x^2 +y^2 = 1
Putting the given value in for x, we can find y to be ...
(-3/4)^2 +y^2 = 1
y^2 = 1 -(-3/4)^2 = 1 -9/16 = 7/16 . . . . . subtract 9/16
y = √(7/16) . . . . . . . . . . . take the square root; y > 0 here
y = (√7)/4
First of all, to simplify expressions we use the PEMDAS
then we do the right needed inverse to move the variables all to one side and the other numbers to another... this is a way we simplify expressions
Hope this helps :)
when we add negative number to the positive number we just subtract the smaller number from the larger number and put the sign or the larger number after words
examples:- First
like here we put + in front of 3 as larger number 5 is positive
<h3>second</h3>
we put negative because 7 is larger then 5 and 7 is negative
