The property of one permits you to multiply or divide the numerator and denominator of a fraction by the same number without changing the value of the fraction. Is there a property of one for addition? Support your answer using examples

Answers

There is not a property of "1" for addition, but the identity property in this case uses "0" instead. If a number is increased by 1, the value will necessary be increased or decreased by the amount added or subtracted. However, if the number either adds or subtracts zero, then value will be left unchanged. Examples: 3+1 = 4, but 3+0 = 3,

I would turn these into fractions. So you do 4 times denominator and then add numerator. Do the same for the other fraction. Afterwards you get 17/4*8/3, which should give you your answer if I'm not mistaken, but I'm not 100% sure on that.

the high school lunch menu repeats every 6 school days the middle school lunch menu reapeat every 8 school days on march 5th both school served chicken wraps what is the next calendar date on which both schools will serve chicken wraps

Answers

Hey! Hope that I can help.

To do this, I circled all the dates on the attached calendar, with red = middle and blue = high. The 6th of March in 2018 is when both schools will have chicken wraps again.
Final answer:

To find the next date both schools will serve chicken wraps, we find the least common multiple of the days their menus repeat, which is 24 days. We then count 18 school days (excluding weekends) from March 5th.

Explanation:

This question is about finding the least common multiple (LCM) of 6 and 8, which are the days that the lunch menus repeat for the high and middle schools respectively. The LCM of 6 and 8 is 24. This means that both schools will serve chicken wraps every 24 school days.

Assuming that March 5th falls on a school day, and that the school operates from Monday to Friday with the weekends off, we subtract weekends from this period. In a span of 24 weekdays, there are usually around 6 weekend days (3 weekends). So, from March 5th, we count 18 school days forward (24 days minus 6 weekend days). The result gives us the next day both schools serve chicken wraps.

A trick coin is made such that when it is tossed there is a 20% chance of heads landing face up and an 80% chance of tails landing face up. If the coin is tossed twice, what is the probability that the coin will land with heads facing up both times?

Answers

P( heads on one toss) = 0.20

P  ( 2 heads)  = 0.20 * 0.20  = 0.04   or 4%

Answer:  4 %

Step-by-step explanation:

According to the question,

20% chance of heads landing face up

Therefore, probability of getting a head, [tex]P(H) = \frac{20}{100} = \frac{1}{5}[/tex]

The probability of getting tail, [tex]P(T) = \frac{80}{100} = \frac{4}{5}[/tex]

Thus, the  probability that the coin will land with heads facing up both times

= [tex]\frac{1}{5}\times \frac{1}{5}[/tex]

=   [tex]\frac{1}{25}[/tex]

=   0.04 or 4 %

Thus the required probability is 4 %.

Answers

17 is the outlier because it is not very close to the other numbers

Answer:

The Outlier is 17.

Step-by-step explanation:

Since 17 is far from other numbers of data set. So, it is an outlier.

Also all other numbers in the data set lie between 69 to 82. But 17 is distinct from other numbers. Hence it is an outlier.

Further, Outlier is the observation which is distinct or has a large distance from other observation. Also, Data set is much affected by the outliers.

At 5 a.m., the temperature at an airport was −9.4°F . Six hours later, the temperature was 2.8°F . Which expression represents the total temperature change over the six hours?

Answers

Let x = the number of hours since 5 a.m.
Let y = temperature, °F

Let the total temperature change be modeled by the expression
y =  ax + b

At 5 a.m., x = 0 and y = -9.4°F. Therefore
b = -9.4

When x = 6 hours, y = 2.8°F. Therefore
6a + b = 2.8
6a - 9.4 = 2.8
6a = 12.2
a = 2.0333

The expression is
y = 2.0333x - 9.4

Answer:
y = 2.0333x - 9.4
where
x = hours since 5 a.m.
y = temperature, °F

Answer:

|2.8 - (-9.4)|

Step-by-step explanation:

The correct answer is |2.8 - (-9.4)|.

twenty-five is the quotient of a number y and 3.5 (write as algebraic expression)

Answers

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as (y / 3.5) = 25.

An explanation of an algebraic expression representing the quotient of a number y and 3.5.

The student is asking to express the statement "twenty-five is the quotient of a number y and 3.5" as an algebraic expression. In algebraic terms, the quotient of y divided by 3.5 is represented by[tex](\frac{y}{3.5})[/tex]or (y / 3.5).

Therefore, the complete algebraic expression that represents this statement is (y / 3.5) = 25.

The algebraic expression for 'twenty-five is the quotient of a number y and 3.5' is 25 = y / 3.5. To find y, you multiply 25 by 3.5.

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as 25 = y / 3.5.

To solve for y, you would multiply both sides of the equation by 3.5 to isolate y. This would give you: y = 25 x 3.5.

Which expression represents this word phrase? seven less than the quotient of x and 9 x−7 9 x÷ 9 7 (x÷9)−7 (9÷x)−7

Answers

The expression that represents 'seven less than the quotient of x and 9' is written as (x / 9) - 7, translating the operations of division and subtraction from the word phrase to algebra.

The word phrase 'seven less than the quotient of x and 9' translates to an algebraic expression by identifying the key terms: 'quotient' refers to division, while 'less than' indicates subtraction.

Specifically, the quotient of x and 9 is expressed as (x \/ 9), and to represent 'seven less than' this quotient, we subtract 7 from it. Thus, the corresponding mathematical expression is (x \/ 9) - 7.

A student applies for a summer internship at different companies. Given this student's previous work experience and grades, there is a chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company. What is the probability this student will receive or more offers?

Answers

Given that a student applies for a summer internship at 5 different companies. Given this student's previous work experience and grades, there is a 40% chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company.

What is the probability this student will receive 2 or more offers? (Round to 3 decimal places.)

This situation describes a binomial distribution with the probability of success = 40% = 0.4 and the number of trials = 5.

P(2 or more offers) = P(2) + P(3) + P(4) + P(5) = 1 - [P(0) + P(1)]

The binomial probability is given by

[tex]\bold{P(x)=\ ^nC_xp^x(1-p)^{(n-x)}} \\ \\ \bold{P(0)}=\ ^5C_0(0.4)^0(1-0.4)^{(5-0)} \\ \\ =1\times1\times(0.6)^5=0.07776 \\ \\ \bold{P(1)}=\ ^5C_1(0.4)^1(1-0.4)^{(5-1)} \\ \\ =5\times0.4\times(0.6)^4=2\times0.1296 \\ \\ =0.2592 \\ \\ \bold{P(0)+P(1)}=0.07776 + 0.2592=0.33696 \\ \\ \bold{\therefore P(2\ or\ more\ offers)}=1-[P(0)+P(1)] \\ \\ =1-0.33696=0.66304[/tex]

Therefore, the probability this student will receive 2 or more offers is 0.663 to 3 decimal places.

Marion Middle School has 600 students. Mike surveys a random sample 7 of 30 students and finds that 7 of them play a musical instrument. How many students at the school are likely to play a musical instrument?

Please explain how as well.

Answers

So if 7/30 students plays an instrument then you'll need to set up an equation for this. The equation you'd use would be:
7/30 = x/600
Then, cross multiply to get:
30x = 4200
Lastly, divide each side by 30 and:
x = 140 students play a musical instrument

Hope this helps!! :)
Do a proportion
7/30=x/600
1. Cross multiply
7x600=4200
30•X= 30x
30x=4200
Divide each side with the number with the variable.
30x/30=4200/30
X=140

how to make a percentage a fraction and a decimal

Answers

Say you have 14 out of 100.  To make that into a fraction, you simply put the first number (as long as it says over or out of) on top and the second on bottom.  You can also make that into a decimal, which would be .14 which is also equal to 14%.

Final answer:

To convert a percentage to a fraction, write it with a denominator of 100 and simplify. To make it a decimal, divide by 100. Convert a decimal to a percentage by multiplying by 100, and to a fraction by writing it with the place value as the denominator.

Explanation:

To convert a percentage to a fraction, you express the percentage value as a fraction with a denominator of 100. For instance, to convert 25% to a fraction, you write it as 25/100, which can be simplified to 1/4. When converting a percentage to a decimal, you divide the percentage value by 100. So, 25% as a decimal is 0.25.

To convert a decimal to a percentage, you multiply the decimal by 100 and add the percent symbol (%). For example, the decimal 0.83 would be 83% when converted to a percentage. To make a decimal a fraction, you express it in terms of its place value as a denominator and simplify if possible. For example, 0.83 can be expressed as 83/100 as a fraction.

Calculating percent composition involves using the part-total relationship. If you know the fractional score, you multiply it by 100 to find the percentage score. For instance, if you get 96 out of 100 on a test, you calculate the percentage composition by dividing 96 by 100 to get 0.96, then multiply by 100 to get 96%.
