How can you tell that a graph is a proportional ( what does it look like and what point will it always go through? )
Answers
Answer:
You can tell if a graph is a proportional relationship, by seeing if the line passes through the origin (0, 0). It looks like a straight line, which comes or goes through the origin.
Answer:
To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship.

3x-3 = 2x-y
3x-2x+y = 3
x + y = 3 ----> (1)
2(x+y) = 3+3y
2x + 2y = 3 + 3y
2x + 2y - 3y = 3
2x - y = 3 -----> (2)
make equation (1) and (2) together
x + y + 2x - y = 3+3
3x = 6
x = 2
now make x = 2 in equation (1)
x + y = 3
2 + y = 3
y = 3-2
y = 1
(x,y) = (2,1)

The area of a cross section through the center of a sphere is 46 square inches. Find the surface area of the sphere.
Answers
Answer:
184 in.^2
Step-by-step explanation:
The cross section through the center of a sphere is a circle whose radius is equal to the radius of the sphere.
area of circle
[tex]A_{circle} = \pi r^2[/tex]
[tex] \pi r^2 = 46 [/tex]
[tex] r^2 = \dfrac{46}{\pi} [/tex]
[tex] r = \sqrt{\dfrac{46}{\pi}} [/tex]
[tex] r = 3.83 ~in.[/tex]
surface area of sphere
[tex] SA = 4 \pi r^2 [/tex]
[tex] SA = 4 \times \pi \times (3.83)^2 [/tex]
[tex] SA = 184~in.^2 [/tex]

The area of the fountain is 147.58 square yards, and the area of the path is 28.25 square yards.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.
Given
a circular fountain,
radius of fountain = √47 yards
area of fountain = πr²
area = π(√47)²
area = 147.58 square yards.
and fountain surrounded by a circular path,
which form a concentric circle with fountain,
the radius of the circular path from center of the fountain = √56 yards
area of the path = total area with radius √56 - an area of fountain
area of the path = π(√56)² - 147.58
area of the path = 175.84 - 147.58
area of the path = 28.26 square yards
Hence the area of the fountain is 147.58 square yards,
area of path = 28.25 square yards.

x P(x) 0 0.25 1 0.3 2 0.1 3 0.35 Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places
Answers
Answer:
The standard deviation of this probability distribution is 1.2.
Step-by-step explanation:
We have that:
P(X = 0) = 0.25
P(X = 1) = 0.3
P(X = 2) = 0.1
P(X = 3) = 0.35
Mean:
Each value multiplied by its probability. So
[tex]M = 0*0.25 + 1*0.3 + 2*0.1 + 3*0.35 = 1.55[/tex]
Variance:
Sum of the squares of the values subtracted from the mean, and multiplied by its probability.
[tex]V = 0.25*(0-1.55)^2 + 0.3*(1-1.55)^2 + 0.1*(2-1.55)^2 + 0.35*(3-1.55)^2 = 1.4475[/tex]
Standard deviation:
Square root of the variance. So
[tex]S = \sqrt{V} = \sqrt{1.4475} = 1.2[/tex]
The standard deviation of this probability distribution is 1.2.
