Answer:
Part A = D
Part B = 5 and 50
Step-by-step explanation:
Part A:
area = 5*4x = 20x
so,
Part B:
to leave it only by x, you divide both sides by 20
100/20 = 5, 1000/20 = 50
which

Answer:
A = Quartile 1 = 74.725
B = Median (quartile 2) = 80.25
C = Quartile 3 = 82.125
D = Minimum = 74.1
E = Maximum = 82.7
Step-by-step explanation:
The values for the data for the average life expectancy are as follows;
North Carolina 79.6
Oregon 82
District of Columbia 77.9
Nevada 81.3
New York 82.5
Colorado 80.9
Alaska 74.9
Connecticut 82.7
Montana 74.1
Mississippi 74.2
Sorting the data we have;
74.1
74.2
74.9
77.9
79.6
80.9
81.3
82
82.5
82.7
The minimum value is 74.1
The maximum value is 82.7
The 1st quartile is the term or 74.725
The median 2nd quartile is the term and the value is 80.25
Third quartile value is the term or 82.125.

Answer:
x= 0 , ,
Step-by-step explanation:
Given, equation is +
=
. →→→ (1)
Now, by cubing the equation on both sides, we get
( +
)³ = (
)³
⇒ (15x-1) + (13x+1) + 3××
(
+
) = 64 x.
⇒ 28x + 3××
(
) = 64x.
(since from (1), +
=
)
⇒ 12× ×
(
)= 36x.
⇒ 3x = .
Now, once again cubing on both sides, we get
(3x)³ = ()³.
⇒ 27x³ = (15x-1)(13x+1)(x).
⇒ 27x³ = 195x³ + 2x² - x
⇒ 168x³ + 2x² - x = 0
⇒ x(168x² + 2x -1) = 0
⇒ by, solving the equation we get ,
x = 0 ; x = ; x =
therefore, solution is x= 0 , ,
