The grade level is treated as categorical when a principal wants to know the number of students from each grade will be participating in a performance.
Variables can be classified into quantitative and categorical. Quantitative variables are those which carry numerical values. Even though a person's grade in school is generally identified by a number, it is a categorical variable. Categorical variables classify data into different groups as the grade level. The grade level categorizes students into different grades and each grade level represents a particular grade only.
Any variable which is partly qualitative and represents groups of data are called categorical variables. Also grade level is ordinal. An example of a situation in which grade level is treated as categorical is when a principal wants to know how many students from each grade will be participating in a performance. Other examples of categorical variables are race, gender, age group, etc.

Line l passes through point (6,0) and line p is the graph of 2x-3y=4. If l is perpendicular to line p, what is the equation of l.
Equation of line p:

[tex]{\sf{y = \frac{2x}{3} - \frac{4}{3}}}[/tex]
Slope of line p (m):

Since, l is perpendicular to line p, the product of slopes of line l & p should be -1. We assume slope of line l be m2
Hence,

X-5y=8
4х+5y=7
Answer:
x = 3 y = -1
Step-by-step explanation:
x - 5y = 8
x = 5y + 8
replace x with 5y + 8 in the other equation
4(5y + 8) + 5y = 7
20y + 32 + 5y = 7
25y = 7 - 32
25y = -25
y = -25/25
y = -1
x = 5(-1) + 8
x = -5 + 8
x = 3

Let
S = 1 + 2 + 3 + … + (n - 2) + (n - 1) + n
Reversing the order of terms, we have
S = n + (n - 1) + (n - 2) + … + 3 + 2 + 1
and we observe that terms in the same position on the right side add up to n + 1.
2S = (1 + n) + (2 + (n - 1)) + (3 + (n - 2)) + … + (n + 1)
There are n terms in the sum, so each the right side is simply n copies of n + 1, and
2S = n (n + 1)
S = n (n + 1)/2
Now,
17 + 18 + 19 + … + 41 + 42 + 43
= (1 + 2 + 3 + … + 41 + 42 + 43) - (1 + 2 + 3 + … + 14 + 15 + 16)

A bird flies from the bottom of a canyon that is 56 1/10 feet below sea level to a nest that is 822 3/10 feet above sea level. What is the difference in elevation between the bottom of the canyon and thr birds best
A bird flies from a nest that is 822 3/10 feet above sea level to the bottom of a canyon that is 56 1/10 feet below it.
The canyon is 737 feet higher than the bird's nest, by a difference of 3 feet.
based on the facts provided, we know that;
The depth below sea level is 52 3/ 5 feet, hence the value would be negative.
The height above sea level is 789 3/ 10, which requires a positive number.
Let's convert the improper fractions from the mixed fractions;
= - 263/ 5 = - 52. 6 feet
789 3/ 10 = 7893/ 10 = 789. 3 ft
the canyon's and the bird's nest's contrasting elevations;
= -52. 6 + 789. 9
Equals 737. 3 feet
Consequently, there is a 737. 3 foot difference in height between the canyon and the bird's nest.

During its year ending june 31, 2021, giant purchased, $3,551,723 of inventory for sale in its stores. how much did giant recognize/record as cost of goods sold for the year ended june 31, 2021?
Cash paid to the suppliers is 35,56,530$
Given here, The Amount of raw material purchased by company is 35,71,723$.
Firstly, we calculate decrease in Accounts payable = 115492$ - 110685$
= 4807$.
Now, cash paid to the suppliers is calculated by,
Cash paid to the suppliers= Purchases of raw material + Decrease in Account payable.
= 35,71,723$ + 4807$
= 35,56,530$
Thus, the cash paid to the suppliers is 35,56,530$.
The amount of Accounts Payable on a company's balance sheet is significant. If AP rises over the previous period, it indicates that the business is using credit rather than cash to purchase more goods and services. A company's accounts payable (AP) will decline if it is paying its commitments from the prior period more quickly than it is acquiring new things on credit.
Management of accounts payable is essential for controlling a company's cash flow. The top component of the cash flow statement, the cash flow from operational activities, shows the net change in AP from the prior period when the indirect method is used to create the cash flow statement.

Find the 14th term of the arithmetic sequence x-1x−1, 7x-77x−7, 13x-13, ...13x−13,...
The 14th term of the arithmetic sequence x-1x−1, 7x-77x−7, 13x-13, ...13x−13,... is -79.
The nth term of a particular arithmetic sequence can be found by, an = a + (n – 1)d. So in order to find the nth term, substitute the given values [tex]a_{1}[/tex] and d into the formula. So to find the 14th term, substitute n = 14 into the equation which is the nth term.
Given,
[tex]a_{1}[/tex]= x-1x-1
[tex]a_{2}[/tex]= 7x-77x−7
[tex]a_{3}[/tex]= 13x-13
n= 14
We have to find the common difference d from differences in adjacent terms [tex]a_{1}[/tex],[tex]a_{2}[/tex],[tex]a_{3}[/tex] . That is,
[tex]a_{2}-a_{1} =a_{3} -a_{2}[/tex]
[tex]7x-77x-7-(x-1x-1)=13x-13-(7x-77x-7)[/tex]
[tex]7x-77x-7-x+x+1=13x-13-7x+77x+7\\-70x-8x=-6+6\\-78x=0\\ x=0[/tex]
Put x=0 in x-1x-1, 7x-77x-7, 13x-13
Therefore,
[tex]a_{1}[/tex] = -1
[tex]a_{2}[/tex] = -7
[tex]a_{3}[/tex] = -13
Then, d will be [tex]-7-(-1)[/tex] or [tex]-13-(-7)[/tex]
So, d= -6
Put [tex]a_{1}[/tex], d, and n in the equation [tex]a_{n} =a+(n-1)d[/tex] to find the 14th term.
Therefore,
[tex]a_{14}=-1+(14-1)-6\\ =-1-78\\=-79[/tex]

The next consecutive binary value of 1011 = 1100
Binary numbers only consist of two digits: 0 and 1. So there are some specific rules for addition in binary. They are:
0 + 0 = 00 + 1 = 11 + 1 = 10(read as one zero and corresponds to the binary value of 2)1 +1 + 1 = 11 (read as one one one and corresponds to the binary value of 3)Here 1011 is a binary number and to find the its next consecutive binary value, we have to add 1 to 1011.
i.e., 1 0 1 1 +

------------------
1 1 0 0
The 0 in the one's place is got by adding 1 + 1 = 10 and 1 is supposed to be a carry to the ten's place. The 0 in the ten's place is got from adding this carry 1 and 1, which again gives 10 and 1 is carry to next place. Now 0 + 1 = 1 and finally we get, 1011 + 1 = 1100.

Answer: 13.6 or 9.2
Step-by-step explanation:
Answer:
x=2/7
Step-by-step explanation:
The most important thing to note is that angle A and angle B are vertical angles. Vertical angles are always equal. So, you can set 4x+2=11x and solve.
To get x by itself, subtract 4x from both sides to get 2=7x. Then divide 7 from both sides which gets x equal to 2/7.

The price for us postage stamps has increased over the years. since 1975, the price has increased from $0.13 in 2005 at a rate that is approximately linear. write a linear model for the price of stamps during this time period. let p represent the price and t represent the number of years since 1975.
It is found that Linear Equation: P = 0.008T + 0.13 and Price of stamp in 2015 = $0.45
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
From 1975 to 2005, 30 years, the price increased from 0.13 to 0.37.
This means the rate of change (slope) = 0.24/30 = 0.008
This means Price changed (increased) by $0.008 per year.
Slope = 0.008
The y-intercept (P) is at the starting point which is at T = 1975; the price was 0.13. Hence y-intercept is 0.13
The equation of a line is given as;
P = mT + b
Where m is the slope and b is the y-intercept.
Now, we can write the linear model equation as;
P = 0.008T + 0.13
Then to find the price of stamp in 2015, we see that this is 40 years later after 1975. So we plug in 40 into T in the equation found above;
P = 0.008(40) + 0.13
P = $0.45
