A marble is drawn at random from the bag shown below. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.What is P(not pink)?
Answer: [tex]\dfrac{3}{5}[/tex]
Step-by-step explanation:
Given : The number of pink marbles in bag= 8
Total number of marbles in bag= [tex]4+5+8+3=20[/tex]
Now, the number of marbles that are not pink =[tex]20-8=12[/tex]
We know that the formula to find the probability is :-
[tex]\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
Similarly, [tex]\text{P(not pink)}=\dfrac{12}{20}=\dfrac{3}{5}[/tex]
Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the mathematical property that she made an error using?
Answer:
Given the expression: [tex](4+5i)+(-3+7i)[/tex]
Aiko rewrites the equation by factoring out the [tex]i[/tex] from the expression and this wrote it as,
[tex](-3+7)i+(4+5)i[/tex]
but this is wrong because [tex]i[/tex] is an imaginary number which is with a number 5 and 7.
Therefore, Aiko cannot factor out the [tex]i[/tex] because it is not present in both numbers -3 and 4
She could rewrote it as
[tex](4-3)+i(5+7)[/tex]
So, she incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.

A cell phone provider offers a plan that costs $30 per month plus$0.20 per text message sent or received. A comparable plan costs $60per month but offers unlimited text messaging.
Complete parts a. and b. below.a. How many text messages would have to be sent or received in order for the plans to cost the same each month?In order for the plans to cost the same, 150 text messages would have to be sent or received.(Simplify your answer. Type an integer or a decimal.)b. If you send or receive an average of 5050 text messages each month, which plan would you choose? Why?The plan with ▼ because ▼ than?
text messages are sent or received each month.
Answer:
a.150
Step-by-step explanation:
We are given that a cell phone provider offers a plan that cots $30 per month plus $0.20 per text message sent or received.
A comparable plan costs $60 per month but offers unlimited text messaging.
a.If number of text messages sent or received =150
For I plan
Cost of one text message sent or received per month=$0.20
Cost of plan per month=$30
Costs of 150 text messages sent or received=[tex]0.20\times 150=$30[/tex]
Hence, total costs of plan I =$30+$30=$60
But in II plan no charge for text message and cost of plan per month is $60
Hence, the text messages 150 would have to be sent or received in order for the plans to cost the same each month.
b.If number of text messages =50
Then the cost of messages in plan I=[tex]02.0\times 50[/tex]=$10
Cost of plan I =$30
Total cost of plan I=30+10=$40
But in second plan no charge for text messaging and cost per month is $60.
Therefore, plan I is better than second plan.Because the cost of plan I is less than the cost of second plan per month.
what is the measure of <RST (MULTIPLE CHOICE)
Answer:
Option D, 77°
Explanation:
The image shown depicts two chords within a circle intersecting creating four separate central angles, two of which have arc measurements listed on the outer edges.
Central angles have the same measurement as the arcs they create, therefore if the arc around ∠RST is 77°, ∠RST itself must have a measurement of 77°.
Find the ending balance: Principal: $600
Interest Rate:5%
Time: 6 Years

The following question has two parts. First, answer part A. Then, answer part B.
Jadyn and Leah were in a fishing tournament. Jadyn's fish weighed 2.120 kilograms. Leah's fish weighed 2.12 kilograms. Part A Jadyn says his fish weighs more because 120 is larger than 12. Is he correct?
Explain your answer. Use place value to support your thinking.
1000 Part B Using the values given, create a correct comparison statement of the weights (in kilograms) using >, <, or = . Math symbols +−×÷(·)[·]=<>≠$°? Previous Next
Answer:
Jadyn's claim is wrong.
Step-by-step explanation:
We are given the following information in the question:
Weight of Jadyn's fish = 2.120
Weight of Leah's fish = 2.12
Jadyn says his fish weighs more because 120 is larger than 12.
Jadyn is incorrect claiming the above fact as:
[tex]2.120 = 2.12\\\\2.120 = \displaystyle\frac{2120}{1000} = \displaystyle\frac{212}{100} = 2.12[/tex]
120 parts out of 1000 are compared to 12 parts of 100 which is equal.

neil has 3 partially full cans of white paint. They contain 1/3 gallion, 1/5 gallion, and 1/2 gallion of paint. about how much paint does neil have in all
Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex] gallons of white paint in total.
Let's calculate the total amount of paint step by step:
1. Convert fractions to a common denominator:
[tex]- \( \frac{1}{3} \) gallon = \( \frac{10}{30} \) gallons[/tex]
[tex]- \( \frac{1}{5} \) gallon = \( \frac{6}{30} \) gallons[/tex]
[tex]- \( \frac{1}{2} \) gallon = \( \frac{15}{30} \) gallons[/tex]
2. Add the amounts of paint in the cans:
[tex]\( \frac{10}{30} + \frac{6}{30} + \frac{15}{30} = \frac{31}{30} \) gallons[/tex]
3. Simplify the fraction:
[tex]\( \frac{31}{30} = 1 \frac{1}{30} \) gallons[/tex]
Thus, Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex] gallons of white paint in total.
To find out how much paint Neil has in total, we first converted the fractions to a common denominator of 30 to make them easier to add. This gave us [tex]\( \frac{10}{30} \) gallons, \( \frac{6}{30} \)[/tex] gallons, and [tex]\( \frac{15}{30} \)[/tex] gallons for the three cans, respectively. Adding these fractions together gives[tex]\( \frac{31}{30} \)[/tex] gallons. To simplify, we divide 31 by 30, resulting in[tex]\( 1 \frac{1}{30} \)[/tex] gallons. Thus, Neil has approximately [tex]\( 1 \frac{1}{30} \)[/tex] gallons of white paint in total.

How do you fact prime numbers
Final answer:
Factoring prime numbers is not applicable as they are already in their simplest form. In calculations involving exponents with prime numbers, exponent rules can be used to simplify or alter the expression. Understanding these rules empowers you to verify the results and improve your mental math skills.
Explanation:
Prime numbers are the building blocks of the number system, but interestingly, they cannot be factored further since they have only two distinct divisors: one and themselves. Therefore, the concept of factoring prime numbers doesn't apply because they are already in their simplest form. However, when you work with exponents and prime bases, such as in 24 × 10¹², you can manipulate the expression by using exponent rules to simplify or alter its form.
Exponents represent how many instances a base number is multiplied by itself. For example, 10³ equals 10 × 10 × 10, which is 1,000. Similarly, when you see an operation like (53)4, you can multiply the exponents (3 × 4) to understand this as 512, which is 5 multiplied by itself 12 times.
Mastering these concepts avoids confusion and allows for mathematical operations to be performed more readily in your head. Calculators handle these numbers with ease, but understanding the rules lets you confirm the accuracy of your work and can help in developing a life-long skill.
