Starting with blue balls, in each of sequential rounds, we remove a random ball and replace it with a new red ball. for example, after the first round we have 9 blue balls and one red ball, after the second round, with probability we have 8 blue balls and 2 red balls, and with probability we have 9 blue balls and one red ball, etc. what is the probability that the ball we remove at the 11th round is blue
The probability that the ball we remove at the 11th round is blue will be 0.6.
How to calculate probability?From the information given, we remove a random ball and replace it with a new red ball. for example, after the first round we have 9 blue balls and one red ball.
Since we have 9 blue balls and remove one every round. Let's assume that the number of blue and red balls will be 6 and 4 respectively in the 11 the round
Therefore, the probability that the ball we remove at the 11th round is blue will be:
= 6/(6 + 4)
= 6/10
= 0.6

do these ratios form a proportion?
Answer:
No, because both of them will never be able to match; become equivalent. You would have to multiply 2 different numbers to make them match, meaning they would not be proportional. For a comparison to be proportional, the ratio you are trying to simplify to must be achieved by multiplying 2 numbers from the previous ratio by one LCD.
[tex]\frac{3\cdot 4}{7 \cdot 3} = \frac{12}{21}[/tex]
They are able to make 12/21, but that does not mean they are proportional.
Solve the inequality for x and identify the graph of its solution (picture added)
The inequality that is correctly graphed is the one in option B.
Which graph correctly describes the inequality?Remember that if we have symbols like ≤ or ≥, we graph a solid circle, while if we use symbols like > or <, we need to use an open circle.
If we write:
x < -3
Then we must have an orange line to the left of x < -3
Finally, the option that you marked is wrong.
Why?
There it says that:
"x < -3 and x > 1"
The "and" means that x meets both properties at the same time, which is impossible.
The correct option is the one that says:
"x < -3 or x > 1".
The "or" means that x needs to meet only one of the two conditions, not both at the same time.
Then the correct option is B.

Cole’s age is 3 years less than his sister Tina’s age, t. If Cole is 18, which equation represents this situation, and how old is Tina?
A.
The equation that represents this situation is t − 3 = 18. Tina is 21.
B.
The equation that represents this situation is t + 3 = 18. Tina is 15.
C.
The equation that represents this situation is 3 − t = 18. Tina is 21.
D.
The equation that represents this situation is -3 − t = 18. Tina is 15.
The equation which represents the situation and how old is Tina is "The equation that represents this situation is t − 3 = 18. Tina is 21".

What number can be used to complete the volume statement for the cone?
a cone with height 4 meters and diameter 3 meters.
volume =
Answer: 9.42 cu. meters
Step-by-step explanation:
V= 1/3 x TT x r^2 x height
TT (pi) = 3.14
r^2 is 1/2 diameter = 1.5
height = 4
V = 1/3 x 3.14 x 1.5^2 x 4
V= 1/3 x 3.14 x 2.25 x 4
V = 9.42 cu. meters
Which regular polygon has a rotation of 240 degree to carry the polygon onto itself?
The regular polygon that has a rotation of 240 degrees to carry the polygon onto itself is the equilateral triangle.
The missing part of the questionOptions
Equilateral triangle
Octagon
Rectangle
Pentagon
How to determine the polygon?A polygon that can carry itself onto itself after a rotation of 240 degrees must obey the following rule:
Angle of rotation = 360/Sides
Next, we test the options:
Option (a) equilateral triangle
Angle of rotation = 360/3
Evaluate
Angle of rotation = 120
Next, we list the multiples of 120
120, 240, 360.....
See that 120 is a factor of 240.
This means that the equilateral triangle would be rotated onto itself when rotated by 240 degrees.

In the following exercises, classify each equation as a conditional equation, an identity, or a contradiction and then state the solution.
23z+19=3(5z-9)+8z+46
15y+32=2(10y-7)-5y+46
The 2 equations are classified as Identities because both sides remain the same for all values of z.
How to Classify Equations?1) We are given the equation;
23z + 19 = 3(5z - 9) + 8z + 46
Let us try z = 0
23(0) + 19 = 3(5(0) - 9) + 8(0) + 46
19 = -27 + 46
19 = 19
Let us try z = 5;
23(5) + 19 = 3(5(5) - 9) + 8(5) + 46
134 = 48 + 40 + 46
134 = 134
Thus, this is an identity as both sides remaining the same for all values of z.
2) We are given the equation;
15y + 32 = 2(10y - 7) - 5y + 46
At y = 0, we have;
15(0) + 32 = 2(10(0) - 7) - 5(0) + 46
32 = -14 + 46
32 = 32
Let us try y = 2;
15(2) + 32 = 2(10(2) - 7) - 5(2) + 46
62 = 26 - 10 + 46
62 = 62
This is an identity as both sides remaining the same for all values of z.

the area of the triangle below is 1/4 square meters. what is the length of the base. express your answer in simplest form
Answer:
4/5
Step-by-step explanation:
Given,
Area of the triangle = 1/4 square meters
From the diagram,
Height = 2/5 m
To find : Length of the base
Formula : -
A = bh/2
Here,
A denotes Area
b denotes Base
h denotes Height
A = 1/4
h = 2/5
A = bh/2
Cross multiply,
A * 2 = bh
2A = bh
2 * (1/4) = b * (2/5)
(1 * 2)/4 = (b * 2)/5
2/4 = 2b/5
1/2 = 2b/5
Cross multiply,
1 * 5 = 2 * 2b
5 = 4b
b = 4/5 meters
Hence,
The length of the base is 4/5 meters.
The length of the base of the triangle is 5/4 meters.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
The formula to find the area of the triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
Given,
Area of the given triangle = 1/4 square meters
Height = 2/5 meters
Substituting in to the formula,
[tex]\frac{1}{2}[/tex] × base × 2/5 = 1/4
1/5 × base = 1/4
Base = 5/4 meters
Hence the base of the triangle is 5/4 meters.

Volume of a right cone with base radius r cm and height h cm :
V = 1/3 π r² h cm³
Surface area :
A = (π r² + π r √(h² + r²)) cm²
Volume of a sphere with radius r cm :
V = 4/3 π r³ cm³
Surface area :
A = 4 π r² cm²
Volume of a cuboid with dimensions r cm × r cm × h cm :
V = r² h cm³
Surface area :
A = 2 r² + 4 r h
a. If the cone and sphere have the same volume, then
1/3 π r² h = 4/3 π r³ ⇒ h = 4r
b. If the area of the cuboid is 98 cm², then
2 r² + 4 r h = 98 ⇒ r (r + 2 h) = 49
c. Since h = 4r, substituting this into the equation from (b) gives
r (r + 8 r) = 9 r² = 49 ⇒ r² = 49/9 ⇒ r = 7/3
d. With r = 7/3, we have
h = 4 × 7/3 = 28/3
and so the volume of the cuboid is
V = (7/3 cm)² (28/3 cm) = 1372/27 cm³
