Answer:
A) Sample statistic
Step-by-step explanation:
A sample statistic is a number computed from values that belongs to a sample, to represent a whole population.
In this case the sample is the home owners in West Virginia that respond this poll in 1971, and the population is U.S.
J + 47 = 55
j = 8
8 is the missing number.
Answer:
Step-by-step explanation:
Fraction :x/y
numerator x = y - 2
Now the fraction can be written as: (y-2)/y
3 is added to both denominator and numerator.
After adding 3, the new fraction = 
The sum of the new fraction and the original fraction is 53/35

35*(2y² + 2y - 6) = 53 *(y² + 3y)
35*2y² + 2y * 35 - 6*35 = 53 *y² + 53*3y
70y² + 70y - 210 = 53y² + 159y
70y² + 70y - 210 - 53y² - 159y = 0
70y² - 53y² + 70y - 159y - 210 = 0
17y² - 89y - 210 = 0
Answer:
The equation is
−4x+7=2y−3
Which can be rewritten as
2y−3 = -4x +7
2y = -4x + 10
y = -2x + 5
The equation represents the line shown in the image below.
Any point that belongs to the line is an ordered pair that represents a solution
To find any ordered pair that satisfies the equation, we place an arbitrary value for x and find the corresponding y value with the equation.
For example
x = 0 ,
y = -2(0) + 5 = 5
(0,5) is an ordered pair
x = 1 ,
y = -2(1) + 5 = 3
(1,3) is an ordered pair
x = 2 ,
y = -2(2) + 5 = 1
(2,1) is an ordered pair
And so on
