how would i use proportions to describe addition to my home

I can think of two ways. First, the increase in floor space or volume. The extra floor space divided by the original floor space is the proportional increase of floor space. If the height of the extra space is uniform and the same as the original height, the volume increase is the same as the floor space (area) increase, but if the shape of the extra space is different then the increase of volume is disproportional and specific measurements would be required to determine the extra volume and therefore the proportional increase in volume. Second, the cost of furnishing plus the cost of decorating the addition. You would need to have a value on the existing furnishings and decor before you could determine the increased cost (or value) as a proportion. (The value of your whole property would increase in proportion to the value of the addition, and you could find out what this was by having the property valued immediately before and after the addition. This would give you a proportion by subtracting the original valuation from the new one and dividing this difference by the original. That would be the proportional increase. Your bedroom has a proportional value compared to your property value, so if you were just considering proportional increase of your bedroom only you would need a formula. Let V be a value associated with the whole property and v be a value associated with your bedroom before any additions then v/V is the proportional value of your bedroom to the value of the whole property. v/V could also be the proportion of your bedroom's floor space or volume to the floor space or volume of the whole property. When the whole property is revalued at V1, and the only additions were in your bedroom, then you could argue that (V1-V)/v represents the proportional increase of the value of your bedroom.) I hope this helps.

How to use "if" & "and" functions in formula bar for calculating exact value of particular cell

This the Excel formula bar? General format IF({test statement},{value if true},{value if false}). IF statements can be nested so that more IF statements can be inserted where the values are. The AND function has the format AND({condition1},{condition2}...) and returns TRUE or FALSE. Combining these we have: =IF(AND(A1>=3,A1<=6),0.3,IF(AND(A1>=6,A1<=12),0.5,IF(AND(A1>=12,A1<=24),1,0))) as the formula in B1. EXPLANATION The three closing brackets or parentheses (")")are necessary to satisfy the "grammar" or syntax. The last one belongs to the first IF statement, the middle one to the second IF statement and the first belongs to the third IF statement. Excel will show a syntax error if any brackets are missing. A quick way of checking is to count the number of opening brackets and the number of closing brackets; they must be the same. In this case, there are 6 of each. Because AND returns TRUE or FALSE it's not necessary to follow it with "=TRUE", although you may do if you wish, but if you do it must come before the comma. The formula bar must start with "=" otherwise, Excel will assume you are writing a string of text. Excel will then help you through construction of the formula. Excel encounters "=" in the formula bar and knows a formula follows. It sees the IF statement and expects 3 parameters separated by commas. The first parameter is the AND function; the second is 0.3 and the third is another IF statement. If the AND result is TRUE, 0.3 goes on B1. Otherwise it moves on to the third parameter, the second IF statement and applies the same logic. The third parameter of the second IF statement is activated if the second AND function returns FALSE, and Excel encounters the third IF statement, applying the same logic. The third parameter of the third IF statement is zero, so B1=0 if the last AND function returns FALSE.

What is the greatest place value in a number, how do you find it?

The greatest place value in a number is the place value of the digit on the far left. Example: 123.456 The digit on the far left is 1. The 1 is in the hundreds place. The greatest place value in 123.456 is the hundreds place. . Note:  Special Condition:  The greatest place value in a number is the place value of the non-zero digit on the far left. We don't usually write things with 0's on the left (00037 vs. 37), but if we do, the greatest place value in a number is the place value of the digit on the far left, ignoring any 0's to the left of the leftmost non-0 digit. Example: 0007.89 Ignore the 0's on the left 7.89 7 is on the far left 7 is in the ones place The ones place is the greatest place value in 0007.89 . Example: 00012300.456 We only remove the 0's on the far left 12300.456 The far left digit is 1 The 1 is in the ten thousands place The ten thousands place is the greatest place value in 00012300.456

solve for y=3x+4, and show both ordered sets on graph

The equation is linear in two variables, x and y. It can't be solved, as such, for particular values of x and y, but a straight line graph represents the dependency of one variable on the other. The graph is a mapping of the function in which the range of values of x and y is the set of all real numbers, so the graph maps x values onto y and y onto x in a unique way: there is only one value of x for a particular value of y, and only one value of y for a particular value of x. There is a real value of x for every real value of y and vice versa, subject to the dependency function y=3x+4, and no real values are excluded. The ordered pair (x,y) forms the set of real numbers satisfying the equation. Every point on the line (and there are an infinite number of them) is an ordered pair, and forms an infinite set. Each ordered pair is effectively a solution to the equation, so there are an infinite number of solutions.

Basic functions

1. What is the range of k(x)=-|x| Asking for the range is another way of asking for valid Y values (or in this case k(x) values). So the range is (-infinity, 0]. 2.Is y=2 a constant function? Yes. Constant functions have no variation in the output for any input. 3. x=-3 a function? No it is not. In order to be a function, there are several properties which must be satisfied, one of which is that for any input, there must be a single output. Often we simplify this by asking "does the function pass a vertical line test?" So if you are to draw a vertical line, would it only cross the function in one place for all values of X? For X=-3, it is a vertical line, so it fails this property of functions because there are an infinite number of solutions (Y values) for this single X value (-3). 4. What is the minimum value of y=x^2-4 The minimum value of parabola's will occur either at the vertex (where its slope is 0) or at its domain boundaries. There are no stated domain restrictions for this function and the slope is 0 at X=0. The first derivative is y'=2x and y'=0 at x=0. The second derivative is y''=2, indicating it is concave for all values X. So the minimum is x=0 and y=-4. For a function with a higher power, there may be more than one minimum (each called local minimum) and any place the second derivative is concave up, both to the left and right segments where the first derivative is 0 will be one of these local minimums. You will take your inputs for each relative minimum and any domain limits (for functions which do not have all real numbers for their domain) and compare the Y values of the original function to determine the absolute minimum for that function.

how do one compute the winsorized mean if the value of "k" is not an integer?

As I understand it, k is either an integer or a percentage. The purpose of winsorization is to reduce the effects of outliers in an ordered dataset. When k is an integer rather than a percentage, k identifies the number of elements from the low and high end that are to be winsorized. Therefore if k is not an integer, it must be a percentage. Let's take the example of k=1.2 and an ordered dataset of 1000 data values. 1.2% is equivalent to replacing the first 12 data with the value of the 13th data value and the last 12 data with the value of the 988th data value. If the sum of the 13th to the 988th data values is S and the 13th data value is L and the 988th is H, then the mean for the whole data becomes (12L+S+12H)/1000. If the sum of the 24 outliers is X, the mean before winsorization would be (S+X)/1000. So the difference in the mean is (12(L+H)-X)/1000=0.012(L+H)-0.001X. That is, 1.2% of the sum of the lowest and highest values in the winsorized dataset less 0.1% of the total of the outliers. The percentage applied to X depends on how much data there is in the dataset. If the size of the dataset was 250 instead of 1000, it would be 0.4% of X, for example.

If you have ever swum in a pool and your eyes began to sting and turn red, you are aware of the effects on an incorrect pH level.

The graph of p(t)=-log(10t) is zero when 10t=1, that is, when t=0.1. The p(t) axis is an asymptote since at t=0, -log(10t) approaches infinity. Therefore the graph starts close to the asymptote when t is just greater than zero, drops very steeply, and crosses the t axis at t=0.1, then it becomes negative but the curve is much shallower. At t=1, p(1)=-1, and p(10)=-2, so the graph drops only 1 unit negatively while t goes from 1 to 10. The scale of both axes needs to be generous, so as to distinguish between values only tiny fractions apart. The pH value of 7 corresponds to a value of 10t=10^-7 or t=10^-8. A pH of 3 corresponds to t=10^-4. For pH values of a reasonable range it is probably best to graph between 0 and 1 given the range 0 to infinity of the pH values, while t goes from 0 to 0.1. If 10-y=0.50 then y=9.50 and -log(10t)=9.50, so 10t=10^-9.50=3.1623*10^-10 and t=3.1623*10^-11. p(t)=-log(10t) so p(1.5t)=-log(15t), where t has increased by 0.50 of its value. The difference between the pH values is p(1.5t)-p(t)=-log(15t)+log(10t)=log(10/15)=log(2/3)=-0.1761, so the pH value falls (becomes more acidic); and p(t+0.5)=-log(10t+5), which requires a specific value for t. p(t+0.5)-p(t)=-log(10t+5)+log(10t)=-log(1+0.5/t). If t is small, as it usually is, 1/t is large and this becomes -log(0.5/t) or log(t/0.5)=log(2t) or log(t)+0.3010. Log(t) is negative so the result is more positive or alkaline. If y=p(t) and 10-y=0.50, y=9.50 and 10t=3.162*10^-10, making t=3.162*10^-11. This is the value of t for a pH of 9.50. p(t+1) would shift the graph 1 unit to the left, so that when t=0 p=-1, making the y-intercept -1.

how do I write an equation based on a two-column table of data?

You need to find a relationship between the independent (we'll call x)  and dependent (we'll call y) variables first. Sometimes it's simple proportionality: y=px where p is a common constant of proportionality for each row of the table; sometimes it's linear: y=px+a where as well as p we have a sort of displacement called the y intercept which is added after applying p, you can tell if's linear by lookin at the difference of consecutive x and y values in the table. If we take two y values y1 and y2 and their corresponding x values x1 and x2 and work out p=(y1-y2)/(x1-x2) for all corresponding listed values in the table, and this calculated value of p is the same for all of them then we have a linear relationship y=px+a. We find a by taking any single row (x, y value) and then a=y-px for whatever (x,y) we picked. The value of a may be positive or negative. If it's inverse proportionality the rule xy=p applies to every corresponding x and y value and we can also have the relationship y=(p/x)+a so a=y-(p/x) for all corresponding pairs (x,y). There are other more complicated relations that can be made into an equation, but the most likely ones for this type of question are the linear relationships, direct and inverse prortionality.

Solve {3x-2y+2z=30, -x+3y-4z=-33, 2x-4y+3z=42}

Solve {3x-2y+2z=30, -x+3y-4z=-33, 2x-4y+3z=42} Please just solve the set provided above!!!! This will be a bit more involved than the systems with two unknowns, but the process is the same. The plan of attack is to use equations one and two to eliminate z. That will leave an equation with x and y. Then, use equations one and three to eliminate z again, leaving another equation with x and y. Those two equations will be used to eliminate x, leaving us with the value of y. I'll number equations I intend to use later so you can refer back to them. That's enough discussion for now. 1)  3x-2y+2z=30 2)  -x+3y-4z=-33 3)  2x-4y+3z=42 Equation one; multiply by 2 so the z term has 4 as the coefficient. 3x - 2y + 2z = 30 2 * (3x - 2y + 2z) = 30 * 2 4)  6x - 4y + 4z = 60 Add equation two to equation four:   6x - 4y + 4z =  60 +(-x + 3y - 4z = -33) ----------------------   5x - y       = 27 5)  5x - y = 27 Multiply equation one by 3. Watch the coefficient of z. 3 * (3x - 2y + 2z) = 30 * 3 6)  9x - 6y + 6z = 90 Multiply equation three by 2. Again, watch the coefficient of z. 2 * (2x - 4y + 3z) = 42 * 2 7)  4x - 8y + 6z = 84 Subtract equation seven from equation six.   9x - 6y + 6z = 90 -(4x - 8y + 6z = 84) ----------------------   5x + 2y      =  6 8)  5x + 2y = 6 Subtract equation eight from equation five. Both equations have 5 as the coefficient of x. We eliminate x this way.   5x -  y = 27 -(5x + 2y = 6) ---------------       -3y = 21 -3y = 21 y = -7  <<<<<<<<<<<<<<<<<<< At this point, I am confident that I followed the correct procedures to arrive at the value for y. Use that value to determine the value of x. ~~~~~~~~~~~~~~~ Plug y into equation five to find x. 5x - y = 27 5x - (-7) = 27 5x + 7 = 27 5x = 27 - 7 5x = 20 x = 4  <<<<<<<<<<<<<<<<<<< Plug y into equation eight, too. 5x + 2y = 6 5x + 2(-7) = 6 5x - 14 = 6 5x = 6 + 14 5x = 20 x = 4    same value for x, confidence high Proceed, solving for the value of z. ~~~~~~~~~~~~~~~ Plug both x and y into equation one. We will solve for z. Equation one: 3x - 2y + 2z = 30 3(4) - 2(-7) + 2z = 30 12 + 14 + 2z = 30 26 + 2z = 30 2z = 30 - 26 2x = 4 z = 2  <<<<<<<<<<<<<<<<<<< Continue using the original equations to check the values. Equation two: -x + 3y - 4z = -33 -(4) + 3(-7) - 4z = -33 -4 - 21 - 4z = -33 -25 - 4z = -33 -4z = -33 + 25 -4z = -8 z = 2   same value for z, looking good Equation three: 2x - 4y + 3z = 42 2(4) - 4(-7) + 3z = 42 8 + 28 + 3z = 42 36 + 3z = 42 3z = 42 - 36 3z = 6 z = 2  satisfied with the results We have performed several checks along the way, thus proving all three of the values. x = 4, y = -7 and z = 2
