Answer: 17/19
Step-by-step explanation:
Number of red rocks = 6
Number of orange rock = 1
Number of blue rocks = 4
Number of white rock = 1
Number of yellow rocks = 7
Total number of rocks = 19
Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.
Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18
Probability of not getting an orange on both occasion will be:
= 18/19 × 17/18
= 17/19

Answer:
The first step is to find the volume of the two hemispheres.
Step-by-step explanation:
[tex]\boxed{volume \: of \: sphere = \frac{4}{3} \pi {r}^{3} }[/tex]
Since the 2 hemispheres have the same radius, we can simply find the volume of a sphere.
Volume of sphere
[tex] = \frac{4}{3}( \pi)( {12}^{3} )[/tex]
[tex] = 2304\pi \: in^{3} [/tex]
Volume of solid
= volume of cylinder -volume of 2 hemispheres
Let's find the volume of the cylinder.
[tex]\boxed{voume \: of \: cylinder = \pi {r}^{2}h }[/tex]
Volume of cylinder
[tex] = \pi( {12}^{2} )(24)[/tex]
[tex] = 3456\pi \: in^{3} [/tex]
Thus, volume of solid
[tex] = 3456\pi - 2304\pi[/tex]
[tex] = 1152\pi[/tex]
[tex] = 1152(3.14)[/tex]
[tex] = 3617.28 \: in^{3} [/tex]
Answer:
Solution :-Volume of solid = Volume of Sphere - Volume of cylinder
Volume = 4/3πr³ - πr²h
Volume = 4/3 • π • 12³ - π • 12² • 24
Volume = 4/3 • π • 1728 - π • 144 • 24
Volume = 4 • π • 576 - π • 3456
Volume = π(3456 - 2304)
Volume = π(1152)
Volume = 3619.11 in³

Step-by-step explanation:
length = [tex]\frac{60}{8}[/tex] = 7.5 in
scale factor = [tex]\frac{image}{original}[/tex] = [tex]\frac{8}{60}[/tex] = [tex]\frac{2}{15}[/tex]
---------------------------------------------------
length = [tex]\frac{192}{4}[/tex] = 48 cm

A map has a scale of 1.5 in : 26 mi. If the distance between city A and City
B on the map 15 inches find the real distance?
Answer:
The real distance is 260 miles
Step-by-step explanation:
From the question;
1.5 inches in map is 26 miles
Thus;
15 inches will be x miles
To get the value of x, we do a cross-multiplication
we have this as:
15 * 26 = 1.5 * x
x = (15 * 26)/1.5
x = 10 * 26 = 260 miles

Find the gradient of the line passing through the points (4a, -a) and (6a, 5a)
Answer:
3
Step-by-step explanation:
Gradient is also called slope .
=> m = y₂ - y₁ / x₂ - x₁
=> m = 5a + a / 6a - 4a
=> m = 6a / 2a
=> m = 3

Write an equation in slope-intercept form of the line that passes through the given points
Answer:
y = - [tex]\frac{4}{3}[/tex] x - 1
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 )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-3}{0+3}[/tex] = - [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = - [tex]\frac{4}{3}[/tex] x - 1 ← equation of line
-0.3x2 + 2x + 3
What is this equation in a table ?

Solve the ineqlality for y.
y - 4x < -7
Answer:
Step-by-step explanation:
So you want to isolate the y, so add 4x to both sides of the problem. So now we have y < -7 + 4x. Now since adding can go both ways (in its own equation) you can turn around the 7 and 4. So we have y < 4x -7

-4x + 10 = 42 what is the value of x
Answer:
x=-8
Step-by-step explanation:
Well subtract 10 on both sides
-4x=32
Div ide -4 on both sides
x=-8
Answer:
x = -8
Step-by-step explanation:
-4x + 10 = 42
-10 -10
-4x = 32
/-4 /-4
x = -8
to check work, insert x into the normal equation
-4(-8) + 10 = 42
32 + 10 = 42
The graph of a system of two linear equations results in two parallel lines.
How many solutions are there for the system?
Answer:
no solutions
Step-by-step explanation:
a "solution" for a system of linear equations is defined as the point(s) of intersection for the two lines.
Parallel lines never touch, so they can never can never intersect
therefore, there are no solutions

Suppose the height of a triangle is tripled. How does this affect the area of the triangle? Explain
Answer:
A' = 3A
Step-by-step explanation:
The area of a triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times h[/tex]
Where
b is base and h is height
If height is tripled, h' = 3h
New area,
[tex]A'=\dfrac{1}{2}\times b\times h'\\\\=\dfrac{1}{2}\times b\times 3h\\\\=3\times \dfrac{1}{2}\times b\times h\\\\=3A[/tex]
So, the new area becomes 3 times the initial area.

In Algebra, we learn about many types of functions. These functions vary from simple to
complex. Think about the different types of functions we've explored so far (linear,
quadratic, and exponential). What features do they share, and how are they unique?
Answer:
they share some features like;exponents,
mathematical signs, variables and more
The shared feature is that the 3 are functions relating y and x, and the uniqueness is on the exponent (or degree for the first two cases).
What the functions have in common?A linear function is:
y = a*x + b
A quadratic function is:
y = a*x^2 + b*x + c
An exponential function is:
y = A*(b)^x
So, the thing that we can see that the functions have in common is that in all of them, the variable y depends on the variable x.
How these functions are different?Well, the exponents are clearly different.
The linear function is of degree 1, the quadratic function is of degree 2, and in the exponential function the variable is in the exponent (it is not a polynomial like in the first two cases).
