Answer: 770 voters in his district.
Step-by-step explanation:
- Population is the largest group of individuals carrying some specific similar characteristics.
- A sample is a subset of population that is used to represents the entire population.
Given : A state representative wants to know how voters in his district feel about enacting a statewide smoking ban in all enclosed public places, including bars and restaurants, as well as several other current statewide issues.
So the population here is : Voters in His districts .
He mails a questionnaire addressing these issues to an SRS (simple random sample) of 770 voters in his district. Of the 770 questionnaires mailed, 147 were returned.
Thus , the sample is : <u>770 voters in his district</u>.
Basically 770 voters is a subset of the entire population voters in his district.
Answer:
x - 2y = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given 2x + y = 3 ( subtract 2x from both sides )
y = - 2x + 3 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
, thus
y = x + c ← is the partial equation
To find c substitute (5, 4) into the partial equation
4 = 
+ c ⇒ c = 
y = x + ← in slope- intercept form
Multiply through by 2
2y = x + 3 ( subtract 2y from both sides )
0 = x - 2y + 3 ( subtract 3 from both sides )
- 3 = x - 2y , that is
x - 2y = - 3 ← in standard form
Answer:
w = 37
Step-by-step explanation:
In order to solve for w you must add 14 to both sides which would be equivalent to w-14+14 = 23 + 14 which would be equal to w+0 = 37 or w = 37. This is allowed because of the addition property of equality which states that if the same number is added to both sides of an equation the equation will continue to be true.
Answer:
=53x+7
Step-by-step explanation:
Distribute:
=8x+−3+(5)(9x)+(5)(2)
=8x+−3+45x+10
Combine Like Terms:
=8x+−3+45x+10
=(8x+45x)+(−3+10)
=53x+7
