A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability of landing on each color.
Answers:
Red = 1/3Yellow = 7/15Blue = 1/5====================================================
Explanation:
Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.
Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5Whoever answers 1-6 gets brainliest! Thank you! I need it ASAP

22. The area of a triangle can be represented by the expression 14x^5 + 63x^2. If the base is 7x^2, write
an expression to represent its height.
Answer:
h = 4x ^ 3 + 18
Step-by-step explanation:
The first thing you should know for this case is that the area of a triangle is given by:
A = (1/2) * (b) * (h)
Where,
b: base.
h: height.
Clearing the height we have:
h = ((2) * (A)) / (b)
Substituting the values
h = ((2) * (14x ^ 5 + 63x ^ 2)) / (7x ^ 2)
Simplifying the expression:
h = ((2) * (2x ^ 3 + 9))
h = 4x ^ 3 + 18
answer
an expression to represent its height is
h = 4x ^ 3 + 18

The geometric mean of a number and four times the number is 22. What is the number?
The number, such that the geometric mean of the number and four times the number is 22, will be 11.
What is the Arithmetic and Geometric mean of two numbers a and b ?The arithmetic mean of two numbers [a] and [b] is equal to (a + b)/2 and their geometric mean is equal to [tex]\sqrt{ab}[/tex]
We have the geometric mean of a number and four times the number is 22.
According to the question, we can write -
G.M. = [tex]\sqrt{ab}[/tex]
Assume that the number is [x]. Then the second number will be [4x]. So -
22 = √4x²
22 = √(2x)²
2x = 22
x = 11
Therefore, the number, such that the geometric mean of the number and four times the number is 22, will be 11.

Answer:
x= −1/5y + 2/5
Step-by-step explanation:
Let's solve for x.
y=−5x+2
Step 1: Flip the equation.
−5x+2=y
Step 2: Add -2 to both sides.
−5x+2+−2=y+−2
−5x=y−2
Step 3: Divide both sides by -5.
Answer:
x= -1/5y + 2/5
not 100% sure if ur trying to solve for x or just graph that equation but hopefully this helped lol :)
Suppose that 10% of people own dogs. If you pick two people at random what is the probability that they both own a dog?
Answer: probability 0.01 %
Step-by-step explanation:
P(A) = 10% = 10/100 = 0.10
pick two people -
= P(A).P(A)
= 0.10 times 0.10
= 0.01
probability = 0.01
The probability that they both own a dog is 1/50 or 0.02.
What is probability?Probability is the chance of happening an event or incident.
Given, 10% of people own dogs.
Let, there are 100 people.
Therefore, the number of people own dogs is
= 100 × 10%
= 10
If I pick two people at random, then the probability that they both own a dog is
= 2/100
= 1/50
= 0.02

The probability that it rains in London on any particular day is 0.3.
If it rains then the probability of it raining the following day decreases to 0.15.
Consider the next two days.
What is the probability it rains on both days?
Answer:
Day 1=0.075
Day 2=0.0375
Step-by-step explanation:
Divide each day by 2
The probability it rains on both days if the probability that it rains in London on any particular day is 0.3 is 0.595
What is the probability?The probability is the likeliness of happening an event. It can be calculated by using the following formula:
Probability=Number of events/Number of total outcomes
How to calculate the probability?
The probability that it rains in London on any particular day is 0.3
If it rains then the probability of it raining the following day decreases to 0.15.
The probability that it rains on the second day=1-0.15=0.85
The probability that it rains on the third day=0.85-0.15=0.7
The probability that it rains on both is=0.85*0.7=0.595
Hence the probability that it rains on both is 0.595

3.) A box in the shape of a rectangular prism has a volume of 180 cm". The length is x cm, the
width is (x + 9) cm, and the height is (x – 4) cm. Find the dimensions of the box.
Answer:
48
Step-by-step explanation:
i am a smart
The dimensions of the box are;
Length = 2.44 cm
Width = 11.44 cm
Height = 1.56 cm
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
Given box in the shape of a rectangular prism has a volume of 180 cm".
The length is x cm, the width is (x + 9) cm, and the height is (x – 4) cm.
Volume = (x + 9) (x – 4) (x)
180 = (x + 9) (x – 4) (x)
180 = (x²+ 9x) (x² – 4x)
x³ + 13x² + 36x - 180 = 0
x = 2.44
Thus, width is (x + 9) cm = 2.44 + 9 = 11.44 cm
The height is (x – 4) cm = 2.44 - 4 = 1.56 cm

Clarissa (the surveyor from our book) is at home and needs to figure out how tall her wall is in order to replace one of the lights. She places the mirror on the ground 27 feet from the wall. Clarissa is 9 feet from the mirror, and Clarissa's eyes are 6 feet from the ground.
Answer:
The height of the wall is 18 ft.
Step-by-step explanation:
I have taken a look at the question, and will label the diagram accordingly. Check the attachment.
We are asked to calculate the height of the wall. Well, the incidence ray is equal to the reflected ray, so therefore by AA we have similar triangles. Setting up a proportion to determine the height of the wall:
9/6 = 27/x [where x = height of the wall]
x = 27*6/9 = 18 ft.

The area of the parallelogram is A = 140 units²
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The sum of angles of a parallelogram is 360°
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the area of the parallelogram be represented as A
Now , the value of A is
Let the height of the parallelogram be h = 14 units
And , base of the parallelogram b = x + y = 10 units
So , A = b x h
On simplifying , we get
The area of parallelogram A = 10 x 14 = 140 units²
Therefore , the value of A is 140 units²
Hence , the area of the parallelogram is 140 units²
