(x, y) = ( ,
)
given the 2 equations
5x - 3y - 10 = 0 → (1)
x + y - 7 = 0 → (2)
rearrange (2) to obtain y in terms of x
y = 7 - x → (3)
Substitute y = 7 - x into (1)
5x - 3(7 - x) - 10 = 0
5x - 21 + 3x - 10 = 0
8x - 31 = 0 ( add 31 to both sides )
8x = 31 ( divide both sides by 8 )
x =
Substitute this value into (3) for y
y = 7 - x = -
=
Answer:
The proportion of the sample that does not have a two-year or four-year college degree is 0.7355.
Step-by-step explanation:
Sample of 310 people.
186(only high school) + 42(only some college) did not have have a two-year or four-year college degree.
So
The proportion of the sample that does not have a two-year or four-year college degree is 0.7355.
Answer:
<h2>3m</h2>Step-by-step explanation:
Volume of a pyramid = 1/3 * Base area * height
If the top of the monument is 11m tall, then the height of the pyramid is 11m. If it will take C of bronze to make the top that is 11 m tall, the volume of the pyramid is 22m³.
Substituting the given data into the formula to get the base area;
Since the base of the pyramid is rectangular in nature,
Base Area = Length * Breadth
Base Area = 6m², and the length of the base is given as 2m, the missing dimension will be the breadth of the rectangle.
6 = 2 * Breadth
Breadth = 6/2
Breadth = 3m
The missing dimension is 3m
