Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case, it is specified that:
Total number of employed writers and authors: 153,000Some college experience but no degree : 12.4%Bachelor's degree or higher : 84.1%Let we have:
writers and authors with bachelor’s degree = N + writers and authors with some college experience and no degree
(so the number of writers and authors with bachelor’s degree is N more than writers and authors with some college experience but no degree)
Number of writers and authors with bachelor's degree = 12.4% of 153000
which is [tex]\dfrac{153000}{100} \times 12.4 = 18972[/tex]
Number of writers and authors with some college experience but no degree = 84.1% of 153,000 which is [tex]\dfrac{153000}{100} \times 84.1 = 128673[/tex]
Thus,
128,673 = N + 18972
or
N = 128,673 - 18972= 109,701
Thus,
Number of Writers and authors with bachelor's degree more than those with only some college experience and no degree is Option b: 109701

Estimate the unit rate.
283 students in 11 classes
Answer:
So estimate.
Really depends on what needs to be estimated, the answer or the overall equation.
So doing the real one first.
283/11 = 25 8/11
You can’t have “part” of a student so rounding this you can go up since 8 is more then half of 11
So 26 students
If you were to round the overall equation then you’d get
280 / 10 which is 28 students per class
So two options.

Sam kept track of the number of problems he was assigned for his math homework on the box plot. A number line goes from 0 to 28. The whiskers range from 4 to 26, and the box ranges from 11 to 26. A line divides the box at 15. Which statement must be true according to the box plot? The data is symmetric and shows that half of the assignments contained 15 problems or fewer. The data is symmetric and shows that the majority of the assignments had 19 problems or more. The data is skewed and shows that half of the assignments contained 15 problems or fewer. The data is skewed and shows that the majority of the assignments had 19 problems or more.
For the box plot of Sam, the data is symmetric and shows that half of the assignments contained 15 problems or fewer.
What is box plot representation of data?Box plot is the way of representation of data which gives the graphical image of the data set to understand better.
The minimum and the maximum values in the box plot is plotted at the end points.
For the box plot which Sam used to keep the track,
The number line goes from 0 to 28- This represents the line on which the box plot drawn.The whiskers range from 4 to 26- The wishers range shows the lowest and highest points. The minimum value of box plot is 4 and maximum value is 26.Box ranges from 11 to 26- This is the interquartile range of the box plot from 11 to 26.A line divides the box at 15- The line which divides the box called the medium line. Thus, the median of the box plot is 15.For the given box plot the data is symmetric, and the medium of the box plot is 15. Thus, the half of the math assignment have less than 15 problem and half of them has more than 15 problems.
Thus, for the box plot of Sam, option A is correct which is, the data is symmetric and shows that half of the assignments contained 15 problems or fewer.

7x-4y=37 6x+3y=51 please
Step-by-step explanation:
2 equations with 2 variables.
either we use 1 equation to express 1 variable by the other and bring this into the second equation to solve for the second variable.
or we do equation arithmetic (subtract one equation from the other so that one variable disorders in the result, and solve for the remaining variable).
since the factors and constants don't seem to be multiples or share nice factors with each other, I suggest the second way.
7x - 4y = 37
6x + 3y = 51
multiply the first equating by 3, and the second one by 4, and then add both equations :
21x - 12y = 111
24x + 12y = 204
------------------------------
45x + 0 = 315
x = 7
then we use one of the original equations to get y :
7×7 - 4y = 37
49 - 4y = 37
12 = 4y
y = 3

Subject: Hypothesis testing and margin of errors
Answer:
See below
Step-by-step explanation:
Problem 4
[tex]H_0:\mu=145\\H_a:\mu>145[/tex]
The null hypothesis, [tex]H_0[/tex], comes from the fact that the nurse initially thinks that the average height of 7th graders is equal to 145 cm.
The alternative hypothesis, [tex]H_a[/tex], comes from the fact that the average height may be greater than 145 cm since the nurse measured the average height to be 147 cm from the random sample.
Problem 5
[tex]H_0:\mu\geq273\\H_a:\mu<273[/tex]
The null hypothesis, [tex]H_0[/tex], comes from the fact that the manufacturer initially thinks that the mean lifetime of a certain type of batteries is at least 273 hours.
The alternate hypothesis, [tex]H_a[/tex], comes from the fact that the sample taken may show that it's actually less given a sample mean of 270.5 hours.
Problem 6
The mass population data set would be most suitable because the average score of a test comes from all those who have taken the test while the sample is the class with 25 students. That sample represents the population of all those that have taken the test.
Problem 7
Because it would take a lot of time and money to check every single child in Africa, it would make the most sense to use the sample data set where your samples come from each village and those samples have the children from each village.
Problem 8
This is a population characteristic because the sample that Sarah took for the average number of children per family represents the entire population.
Problem 9
This is a sample characteristic because the size of the sample was clearly large, this was a study, and other claims made.

-1/4(x+1 2/3)=-2 1/5
Answer:
x=\frac{64}{5}=12\frac{4}{5}
Step-by-step explanation:
1. Simplify the expression
\frac{-1}{4}\cdot\left(x+\frac{12}{3}\right)=\frac{+\left(-21\right)}{5}
Find the greatest common factor of the numerator and denominator:
\frac{-1}{4}\cdot\left(x+\frac{\left(4\cdot3\right)}{\left(1\cdot3\right)}\right)=\frac{+\left(-21\right)}{5}
Factor out and cancel the greatest common factor:
\frac{-1}{4}\cdot\left(x+4\right)=\frac{+\left(-21\right)}{5}
Multiply the fractions:
\frac{\left(-1\cdot\left(x+4\right)\right)}{4}=\frac{+\left(-21\right)}{5}
Expand the parentheses:
\frac{\left(-x-4\right)}{4}=\frac{+\left(-21\right)}{5}
Break up the fraction:
\frac{-x}{4}+\frac{-4}{4}=\frac{+\left(-21\right)}{5}
Find the greatest common factor of the numerator and denominator:
\frac{-x}{4}+\frac{\left(-1\cdot4\right)}{\left(1\cdot4\right)}=\frac{+\left(-21\right)}{5}
Factor out and cancel the greatest common factor:
\frac{-x}{4}-1=\frac{+\left(-21\right)}{5}
Answer:
The answer is x= 7 2/15. So the third one.

Answer:
x=30 ; y=60 ; z=120.
Step-by-step explanation:
(we can solve it in a system.)
z+2x=180 => z=180-2x
y+4x=180 => y=180-4x
y+z=180
4x+2x=180 => 6x=180 => x=30
<=>
z=180-2*x=180-2*30=180-60=120
y=180-4x =180-4*30=180-120=60
A group of friends shared the cost of a printer. If John, Carl and Jason each paid $15, $25, and $112 respectively, then Carl paid what percent of the cost of the printer?
The percent of the cost of the printer Carl paid is 16.45%
The total cost of printerSince John, Carl and Jason each paid $15, $25, and $112 respectively, the total cost of the printer is T = $15 + $25 + $112 = $152
Since Carl paid $25, we need to find the percent of the total amount Carl paid.
Percent Carl paidSo, percent Carl paid = amount Carl paid/total cost × 100 %
Since amount Carl paid = $25 and total cost = $152,
Substituting the values of the variables into the equation, we have
percent Carl paid = amount Carl paid/total cost × 100 %
percent Carl paid = $25/$152 × 100 %
percent Carl paid = 0.1645 × 100 %
percent Carl paid = 16.45%
The percent of the cost of the printer Carl paid is 16.45%
