If the data for the heights of players on a basketball team is skewed right, which statistical measure represents the spread of the data best?
A. Interquartile Range
B. Mean
C. Median
D. Range
Answer:
Median
Step-by-step explanation:
I know that you can't do Range, since it's skewed right.
The mean can't be it since it's also not representative when it's skewed right.
I'd say Median, or IQR at first glance but if you look at a graph, the IQR might follow with the skewed and move over a bit.
That leaves Median.
The correct statistical measure which represents the spread of the data best is, Median.
Given that;
The data for the heights of players on a basketball team is skewed right.
Since, We know that;
For the data for the heights of players on a basketball team is skewed right,
We can use Median for the spread of the data best.
Hence, The correct statistical measure which represents the spread of the data best is, Median.

18/5 divided by 3/25
[tex] \frac{18}{5} \div \frac{3}{25} [/tex]
Answer:
30
Step-by-step explanation:
There are a few different ways we can approach this problem.
The easiest way is to flip the second fraction and multiply:
[tex]\dfrac{18}{5} \div \dfrac{3}{25}=\dfrac{18}{5} \times \dfrac{25}{3}=\dfrac{18 \times 25}{5 \times 3}[/tex]
To do this without a calculator, rewrite 18 as 6 x 3 and 25 as 5 x 5:
[tex]\dfrac{18 \times 25}{5 \times 3}=\dfrac{6 \times 3 \times 5 \times 5}{5 \times 3}[/tex]
Now we can cancel out the common factors of 5 and 3 from the numerator and denominator, and are left with:
[tex]\implies 6 \times 5 =30[/tex]
The quotient obtained from the division of given fractions is 30.
Given that, 18/5 divided by 3/25.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 18/5 ÷ 3/25
= 18/5 × 25/3
= 6/1 × 5/1
= 30/1
Therefore, the quotient obtained from the division of given fractions is 30.

26 rooms on 2 floors = ____ rooms on 4 floors
Answer:
There would be 104 rooms on 4 floors in total.
Step-by-step explanation:
If there were 26 rooms on 2 floors, then you multiply 26 x 4, the result would be 104 rooms on 4 floors in total.
Answer:
52 rooms
Step-by-step explanation:
you could set up a proportion to solve this
26 rooms/ 2 floors = ?/4 floors
to find the answer for the question mark you can divide the amount of rooms by floors and get 13.
With the 13 you can multiply that by 4 to get 52 rooms. You basically used the 13 as the amount of increase

Answer:
<1 = 88° , <2 = 129°, <3 = 82°, <4 = 147°, <5 = 94°, <6 = 86°
Step-by-step explanation:
<1 + 92° = 180°
<1 = 88°
<2 + 51° = 180°
<2 = 129°
<3 + 98° = 180°
<3 = 82°
<4 + 33° = 180°
<4 = 147°
<1 + <2 + <3 + <4 + <5 = 540°
88° + 129° + 82° + 147 + <5 = 540°
<5 = 94°
<5 + <6 = 180°
94° + <6 =180°

Answer:
A, D
Step-by-step explanation:
You want to know the bound for the values of Sn and Tn, given their definitions as ...
[tex]\displaystyle S_n=\sum_{k=1}^n{\dfrac{n}{n^2+kn+k^2}}\\\\T_n=\sum_{k=1}^{n-1}{\dfrac{n}{n^2+kn+k^2}}[/tex]
ValuesAll we need to do to determine the correct answer choices is evaluate the sums for some value of n.
For n=2, the value of S2 is ...
S2 = 2/(4+2+1) +2/(4+4+4) = 2/7 +2/12 = 19/42 ≈ 0.4524
For n=2, the value of T2 is ...
T2 = 2/(4+2+1) = 2/7 ≈ 0.2857 . . . . . 1/(3n) less than the value of Sn
Both of these values are less than π/(3√3) ≈ 0.6046.
The correct answer choices are ...
A) Sn < π/(3√3)
D) Tn < π/(3√3)
__
Additional comment
For the purpose here, it is not necessary to determine the limiting value of either Sn or Tn. It is only necessary to demonstrate which side of the given value the terms of either sequence lie.

Consider this dilation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain and show your work.
ANSWER BOTH PARTS YOU MAY GET EXTRA POINTS!
Answer:
reductionscale factor 1/2Step-by-step explanation:
The usual English meanings of the words "reduction" and "enlargement" apply to geometrical figures.
(a)Figure A'B'C'D' is smaller than figure ABCD, so represents a reduction.
__
(b)Every coordinate of every image point is half as far from the origin in A'B'C'D' as in the original figure ABCD. For example, the x-coordinate of C' is 2, and the x-coordinae of C is 4. The dilation factor is the ratio of these values:
k = Cx'/Cx = 2/4 = 1/2
The scale factor is 1/2.
