The dataset below represents the population densities per square mile of land area in 15 states in the 2010 U.S. Census. What is the interquartile range?
Answers
Answer:
The Interquartile range is 188
Step-by-step explanation:
Missing Data:
1,19,35,43,49,55,63,94,105,110,175,231,239,351,738
Required
Determine the Interquartile range (IQR)
The given data is ordered already.
First, we need to determine the median
For odd number of data
Median = ½(n + 1)th
In this case, n = 15; so
Median = ½(15 + 1)th
Median = ½(16)th
Median = 8th
This implies that the median is at the 8th position.
So, we have:
1,19,35,43,49,55,63 ----> Lower
(94) ---- Median
105,110,175,231,239,351,738 ---- Upper
Next, we determine the median of the lower and upper sets.
These are called lower quartile (Q1) and upper quartile (Q3) respectively
Lower: 1,19,35,43,49,55,63
Number of data, n = 7
Q1 = ½(n + 1)th
Q1 = ½(7 + 1)th
Q1 = ½(8)th
Q1 = 4th position
From the list of data in the lower set,
Q1 = 43
Upper: 105,110,175,231,239,351,738
Number of data, n = 7
Q3 = ½(n + 1)th
Q3 = ½(7 + 1)th
Q3 = ½(8)th
Q3 = 4th position
From the list of data in the upper set,
Q3 = 231
IQR is then calculated as thus:
IQR = Q3 - Q1
IQR = 231 - 43
IQR = 188
What theorems can be used to prove the triangles are congruent?
Answers
Use the number line to help you decide which statement is true.
Answers
Answer:
A
Step-by-step explanation:
because 1/2 = 4/8
and 5/8 is greater than 4/8
The number line is the representation of numbers in real order.
5/8 = 0.625
1/2 = 0.50
5/8 is greater than 1/2.
Option A is the correct answer.
What is a number line?It is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
Example: Number line from -4 to 4.
-4__-3__-2__1__0__1__2__3__4
We have,
5/8 > 1/2
5/8 = 1/2
5/8 < 1/2
5/8 = 0.625
1/2 = 0.50
We see that,
0.625 > 0.50
So,
5/8 must be greater than 1/2
i.e
5/8 > 1/2
We can also find the relation between 5/8 and 1/2 in this way.
5/8 = 1/2
Cross multiply.
5 x 2 = 8
10 = 8
10 is greater than 8
So,
5/8 is greater than 1/2
5/8 > 1/2
Thus,
5/8 = 0.625
1/2 = 0.50
5/8 is greater than 1/2.
Option A is the correct answer.

A laser beam is aimed 25° from horizontal at a mirror 120 m away. The beam bounces off the mirror and continues for an additional 90 m at 20° above horizontal until it hits a target, mirror 2. What is the distance between the origination point and the target?
Answers
Answer:
A. Approximately 85 m
Step-by-step explanation:
edge
The required distance between the origination point and the target point is 85 m.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
Here,
The distance between the origination point and mirror 1 is 120 m and between mirror 1 and mirror 2 = 90 m
From geometry, the measure of the angle Opposite the distance between the origination point and the target is given as,
= 20 + 25 = 45°
Let,
a = x
b = 90 m
c = 120 m
A = 45°
Following the cosine rule,
a² = b² + c² -2bccosA
a² = 90² + 120² - 2×90×120×cos45
a = √7226.5
a = 85.008
a ≈ 85
Thus, the required distance between the origination point and the target point is 85 m.

Answers
Answer:
M<2= 65
Step-by-step explanation:
The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.
You would use angle addition postulate to find the answer so M<1 + M<2 = 180.
Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180
Then you would subtract 115 from 180 in which you would get M<2 = 65

fully simplified form.
Answers
Answer:
Step-by-step explanation:
Rewrite the equation
Start multiplying
Simplify
The value of ab³ in simplified form is equal to -250(i + 1).
What is an equation?Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. A statement is not even an equation if there is no "equal to" sign in it.
From the given values in the question,
a = -2 + 2i
b = -5i
ab³ = (-2 + 2i) × (-5 i)³
= (-2 + 2i) (-125 i³)
= (-2 + 2i) (-125 (-i))
= (-2 + 2i) (+125 i)
= 125 i(-2) + 125 i(2i)
= -250 i + 250 i²
= -250 i -250 or,
ab³ = -250 (i+1)

determine if the following lengths make a triangle 6,3,7
Answers
Answer:
Yes
Step-by-step explanation:
The rule is that if a+b>c, then it's a triangle. In this case, 6+3>7, so it's a triangle. The hypotenuse (7) should always be the largest of the sum of the two side lengths.
Answer:
Yes, the lengths will create a triangle.
Step-by-step explanation:
6 + 3 = 9 > 7
3 + 7 = 10 > 6
6 + 7 = 13 > 3
If the combination of any lengths is greater than the remaining length, then the lenghts will create a triangle.
