The heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the interquartile range of the data set.
The interquartile range of the data set is 21.
Given that the heart rate of 10 adults is measured and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121.
The interquartile range shows the extent of the middle half of the distribution. Quartiles segment any distribution, ordered from low to high, into four equal parts. The interquartile range (IQR) contains the second and third interquartile ranges, the central half of the dataset.
The value of quartile 1 is Q₁=90
The value of quartile 3 is Q₃=111
So, the interquartile range is
IQR=Q₃-Q₁
IQR=111-90
IQR=21
Hence, the interquartile range of the data set 83, 87, 90, 92, 93, 100, 104, 111, 115, 121 is 21.

An exponent that is over a whole entire fraction can be split up and put separately onto the numerator (top number) and denominator (bottom number) See image.
Then you can get rid of a negative exponent (make it positive) by moving the whole term across the fraction bar. The top moves to the bottom and the bottom moves to the top. See image.

The length of a rectangle is 6 less than twice the width. If the perimeter is 60 inches, find the length and width.
Answer:
w = 12
l = 18
Step-by-step explanation:
Hello!
Recall the perimeter of a rectangle is twice the sum of the length and the width of the rectangle.
[tex]P = 2(l + w)[/tex]Let w be the width. The length is 6 less than twice the width. That means, l is 2w - 6.
Plug it into the formula and solve, given that P is 60.
Solve for w[tex]P = 2(l + w)[/tex][tex]60 = 2(2w - 6 + w)[/tex][tex]60 = 2(3w - 6)[/tex][tex]60 = 6w - 12[/tex][tex]72 = 6w[/tex][tex]w = 12[/tex]The width is 12 inches. We can plug in 12 for 2w - 6 to find the length.
Solve for l[tex]l = 2w - 6[/tex][tex]l = 2(12) - 6[/tex][tex]l = 24 - 6[/tex][tex]l = 18[/tex]The length is 18 inches.
The width is 12 inches, and the length is 18 inches.

The coordinates of the circumcenter of triangle having coordinates of (0,0),(4,0),(4,-3) are (1,-17/6).
Given The coordinates of triangle are (0,0),(4,0),(4,-3).
Let the triangle be ABC.

------------------------------------2/5 (1/3x - 15/8) - 1/3(1/2 - 2/3x)
Your question presented was: [tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )-\frac{1}{3} (\frac{1}{2} -\frac{2}{3}x)[/tex]
Okay, lets distribute this problem and break it into two parts. We will distribute 2/5 and -1/3 to the numbers in parenthesis. This is the distributive property.
Step 1.
[tex]\frac{2}{5} (\frac{1}{3} x-\frac{15}{8} )[/tex] when distributed is [tex]\frac{2}{15} x - \frac{30}{40}[/tex]
Please note that -1/3 can be rewritten as + -1/3. So you must distribute the negative.
Step 2.
[tex]\frac{-1}{5} + \frac{2}{9} x[/tex]
So..lets put the 2 parts of the equation together
[tex]\frac{2}{15} x - \frac{30}{40}[/tex] + [tex]\frac{-1}{5} + \frac{2}{9} x[/tex] can be simplified by getting the common denominator.
You can only add like terms, so those fractions with x can only be combined with x.
Step 3.
Lets reformat while we're at it
[tex]\frac{6}{45} x + \frac{10}{45} x -\frac{30}{40} -\frac{8}{40}[/tex]
We got 45 because the LCM (Lowest Common Multiple) of 15 and 9 was 45. We multiplied both sides of the fraction by 3 for 2/15x and we multiplied by 5 on both parts of the fraction for 2/9x.
Now we combine.
Step 4.
[tex]\frac{16}{45}x-\frac{38}{40}[/tex]. We can still simplify!
Step 5.
-38/40 can be simplified by a common factor, 2! So our final answer is
[tex]\frac{16}{45}x-\frac{19}{20}[/tex]

A parabola with a vertex at (0,0) has a focus along the negative part of the x-axis.
Which could be the equation of the parabola?
y2 = x
y2 = –2x
x2 = 4y
x2 = –6y
The equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y. (Correct choice: D)
How to determine the best equation of the parabola based on given characteristics
In accordance with the statement, we find that the parabola has its vertex at the origin, therefore it is horizontal and its vertex constant (C) is negative as its focus is in the negative part of the x-axis. Therefore, the equation of the parabola in standard form has the following form:
x² = C · y, for C < 0. (1)
In consequence, the equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y.

In the beginning, they have 50 and 180 cows respectively.
How to find the total number of cows?The two farmers bought a total of 230 cows .
A year later the first farmer had 10% more cows than in the beginning.
Therefore,
let
x = number of cow he has initially.
A year later the percentage increase = 0.1x
whereas the second had 20% increase. Therefore,
let
y = number of cow he has initially.
A year later percentage increase = 0.2y
Hence,
x + y = 230
1.1x + 1.2y = 263
1.1x + 1.1y = 253
1.1x + 1.2y = 263

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of GF is 254 units.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
Since a centroid of a triangle divides the median into a ratio of 2:1. Therefore, the ratio of AG: DG is,
AG / DG = 2/1
(19x+14)/(9x+20) = 2/1
19x + 14 = 18x + 40
19x - 18x = 40 - 14
x = 26
Assuming the triangle is an equilateral triangle, therefore, the length of GF will be,
GF = DG = 9x+20
GF = DG = 9(26) + 20
GF = 254 units
Hence, the length of GF is 254 units.

This represents x + 1
On the vertical axis, we have:
3 columns beside the big square.
This represents x + 3
So, we have:
(x + 1) * (x + 3)
Expand
(x + 1) * (x + 3) = x^2 + x + 3x + 3
