what value of t makes the following equation true?
Answer:
t = 108
Step-by-step explanation:
[tex]\frac{5}{9}[/tex] t - 27 = [tex]\frac{1}{9}[/tex] t + 21 ( subtract [tex]\frac{1}{9}[/tex] t from both sides )
[tex]\frac{4}{9}[/tex] t - 27 = 21 ( add 27 to both sides )
[tex]\frac{4}{9}[/tex] t = 48 ( multiply both sides by 9 )
4t = 432 ( divide both sides by 4 )
t = 108

Which is the most reasonable measure of central tendency for the data set?
mean
mode
range
median
Answer:
I think its range I dont know
Step-by-step explanation:
The mean is the maximum often used as a degree of critical tendency because it makes use of all values inside the information set to give you an average. For statistics from skewed distributions, the median is higher than the implied because it isn't motivated through extremely big values.
The correct option is A.
Which is a better measure of center mean or median?The median is normally a better degree than the middle whilst there are intense values or outliers because it isn't always stricken by the right numerical values of the outliers. The suggestion is the maximum common measure of the middle. The phrases “mean” and “common” are regularly used interchangeably.

B f(x)= 4x+12/x^2 + x-6
C f(x)= 4/x+2
D f(x)= 4x-8/x^2 +x-6
Answer:
The answer should be D
Step-by-step explanation:
sorry if it's wrong, I just did this test the other day and I forgot if I got it right.
The rational function that is represented by the given graph is [tex]f(x) = \frac{4x - 8}{x^{2} +x-6}[/tex]
What is a polynomial function ?Rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.
We need to find out which rational function is represented by this graph.
Firstly, we see that graph does not exist at x = -3 and x = 2.
Thus, (x+3) and (x-2) cannot be equal to 0.
(x + 3)(x - 2) = x² + x - 6
Thus, the denominator of the function is x² + x - 6.
So, our solution can be B. or D.
We can also see that there is a circle over the graph at x = 2. This means that f(x) is undefined at x = 2. It is possible only if f(x) = ∞/∞ or 0/0 at x = 2.
On putting the value of x = 2 in both B. and D., we find that in D. f(x) = 0/0 at x = 2.
[tex]f(2) = \frac{4*2 - 8}{4 + 2 - 6} = \frac{0}{0}[/tex]

Here is a diagram of triangle DEF.
Find the measures of angles q, r, and s.
(PLEASE help ASAP I will give brainliest!)
Answer:
q= 100
r= 135
s= 125
Step-by-step explanation:
These are the angles
The measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
These are the angles
⇒ q = 180 - 80 = 100
⇒ r = 180 - 45= 135
⇒ s = 180 - (180 - 80 - 45) = 125
So the sum of the measures of angles q, r, and s
⇒ q + r + s = 100 + 135 + 125 = 360°
Thus, the measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

When you have a lot of the same kind of problem to solve, it makes a certain amount of sense to let a spreadsheet do it. You can enter the formulas once, and then all you need to do is supply the different data for the different problems.
Here, we can put the equations into standard form, then use Cramer's Rule to solve them. For the two equations ...
ax +by = cdx +ey = gwe can define ...
D = (ae -db)
Then the values of x and y are ...
x = (ce -gb)/D
y = (ag -dc)/D
The attached spreadsheet implements these equations to find the values of x and y.
__
The second equation of the 2nd Question is not given in standard form. To put it into standard form, we need to subtract 4y from both sides:
x -4y = -5

Many graphing calculators have matrix functions that will solve sets of linear equations, too. For those, you can use the function that puts the coefficient matrix into Reduced Row-Echelon Form. Often that function is named RREF( ), as it is on my TI-84 and HP-48 calculators. The input coefficient matrix will look like ...
[tex]\left[\begin{array}{ccc}a&b&c\\d&e&g\end{array}\right][/tex]
and the output matrix will look like ...
[tex]\left[\begin{array}{ccc}1&0&\text{x-value}\\0&1&\text{y-value}\end{array}\right][/tex]
Effectively, the equations are solved by "elimination." If the calculator shows [0 0 0] in the bottom row of output, it means the equations are dependent and there are infinite solutions. If it shows [0 0 1], the equations are inconsistent, and there are no solutions.

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centimetres. Write down, in imillimetres, the lower bound of his measurement.
The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the measured magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
[tex]y = x + \epsilon[/tex] (1)
Where:
[tex]x[/tex] - Measured magnitude, in millimeters.[tex]y[/tex] - Possible magnitude, in millimeters.[tex]\epsilon[/tex] - Uncertainty, in millimeters.If we know that [tex]y = 67.5\,mm[/tex] and [tex]\epsilon = 1\,mm[/tex], then the lower bound of the measurement is:
[tex]y = 67.5\,mm - 2\cdot (1\,mm)[/tex]
[tex]y = 65.5\,mm[/tex]
The lower bound of the measurement is 65.5 millimeters.
