Answer: 1/5

Step-by-step explanation: the probability that you get heads on the coin is 1/2 and the probability for getting a vowel out of incredible is 4/10 or simplified 2/5. So you multiply... 1/2 x 2/5 = 1/5

Hello!

I see this question relates to mathematics in the topic, geometry.

I have personally learned about rotations and reflections, and would like to knowledge you to the best of my abilities based on the question you have asked.

A rotation and reflection are all translations.

Translations move the figure but don't change its size.

A dilate changes the size of the figure by a scale factor.

All of these mentioned are transformations.

I am not sure if there is a theorem that used rotations and reflections, but i do no that rotations and reflections are both translations.

I hope you found this well,

And have a wonderful day.

Thank you for your support,

Step-by-step explanation:

area of rectangle = 20 x 11 = 220 cm²

area of circle = π4² = 50.24 cm²

deduct circle from rectangle area = 220 - 50.24 = 169.76 cm²

The answers to all parts are:

1. 33%

2. Likely

3. 1/3

C. 2:4

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Red marble= 3

Yellow marble = 2

Blue marble = 1

So, the percent of change of choosing yellow marble

= 2/6 x 100

= 33.33%

2. The likelihood of a yellow marble being selected on the first draw is likely.

3. The probability of a yellow marble being selected on the first draw

= 2/6

=1/3

4. The odds of a yellow marble being selected on the first draw

= 2:4

Answer: 17

Step-by-step explanation:

A dot plot is a basic type of data visualization in which data points are represented as dots on a graph with x and y axes. The total number of albums in Sai’s collection is 17.

A dot plot, also known as a strip plot or dot chart, is a basic type of data visualization in which data points are represented as dots on a graph with x and y axes. These charts are designed to visually represent certain data patterns or groups.

For the given dot plot, Each dot represents an album. Therefore, the total number of albums in Sai’s collection is the total number of dots in the dot plot.

Now, the number of dots in the dot plot is 17.

Hence, the total number of albums in Sai’s collection is 17.

Answer:

You would expect the arrow to land on an even number about 25% of the time.

Step-by-step explanation:

In the sector labeled 1 you would expect it to land on it 50% of the time because that sector takes up 50% of the spinner. For the rest of the sectors, you would take to the remaining 50% and divide it by four for the four other sectors on the spinner.  50 ÷ 4 = 12.5 Then you would take the number of even numbers there are on the spinner, which is two in the case, and add those percentages together. 12.5 + 12.5 = 25

Answer:

5x18

Step-by-step explanation:

5x6x3 and 5x18 equal 90

Answer:

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

Step-by-step explanation:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.

Answer:

a. $450

b. $135

c. 70%

Step-by-step:

[tex]\frac{70}{100} = \frac{315}{450}[/tex]  since these two fractions are equal to each other that means the orginal price is $450.

(sale price/original price)x100= % of original price

(315/450)x100=0.7=70%

Answer:

What is factoring?

Factoring is finding what to multiply to find an expression. It is like splitting expression into a multiplication of simplified expression.

Why is it useful to try to factor out the GCF first when factoring?

Greatest common factor or GCF of two numbers is the largest number that divides evenly in both numbers, GCF works the same in polynomials, which divide the expression evenly .

Explain the relationship between factoring and multiplying polynomials. Give an example to help explain

Factoring take away the multiplication, to factorize a polynomial it means take apart what  is multiplied. the best example is a²+b²+2ab ( multiplied)

factorize :(a+b)(a+b)   take apart what is multiplied

Factor x^2-25, 3x^2-12x-15, and x^3+2x^2+3x+6

x²-25  =(x+5)(x-5)

3x²-12x-15 = 3(x²-4x-5)  GCF=3

3(x-5)(x+1)

x³+2x²+3x+6  (x+2) common factor

(x+2)(x²+3)

What are the key features needed to graph a polynomial function?

the key features are the vertex, axis of symmetry, x and y intercept

Explain how to find these key features to sketch a rough graph of a polynomial function

parabola : y=ax²+bx+c

ex: 3x²-12x-15

find vertex (h,k)

h=-b/2a =-(-12)/2(3)=2

k=f(h)=f(2)=3(2)²-12(2)-15

k=12-24-15=-27

vertex=(2,-27)

x intercept is when the graph =0 (y=0)

y intercept when x=0 then y= the constant c and where the graph cross the y axis

axis of symmetry is the x of the vertex: is a line about which a parabola is symmetrical and vertical when the axis of symmetric is vertical.

Why would someone want to factor a polynomial? Provide real world examples of different questions we can answer or facts we can determine from factoring a polynomial.

factor a polynomial helps us understand more about equations,factoring helps us rewrite the polynomial into simpler expression.

example from real life:

A homeowner has a back yard and wants to turn it to garden beds so he can plant his vegetables, he wants to fill it with dirt he needs 240 cubic feet to fill it  the length is 4 feet than the width , and the height is 4

solve:

length=W+4

height=1/3 w

V=length* width* height

240=(w+4)(w)(4)

351= 4w²+16w

4w²+16w-240=0

take 4 as common factor

4(w²+4w-60)

now factorize:

4(w-6)(w+10)=0

Answer:

the numbers 2 and 6 are both the modes.

Step-by-step explanation:

the mode is the number that appears the most. if there are two numbers that appear most often (and the same number of times) then the data has two modes.

Answer:

6 and 2 is your answer

Step-by-step explanation:

1. You have the numbers 2, 6, 8, 3, 4, 6, 2, 6, 8, 5, 6, 2, 7, 8, 4, 3, 2, 7, 3, 4

2. Count how much each number occurs.

2 occurs 4 times

6 occurs 4 times

8 occurs 3 times

3 occurs 3 times

4 occurs 3 times
