Use the coefficient of variation to determine
which data set varies the most.
on
Data Set 1: 2 = 12 and s = = 7
Data Set 2: 2
0.12 and s
= 0.3.
Data Set 1 CV ~
% (Round to the
nearest percent)
Data Set 2 CV =
%
Answer:
Dataset 2
Step-by-step explanation:
The Coefficient of variation is the ratio of the standard deviation and the population mean.
Data Set 1: 2 = 12 and s = = 7
Data Set 2: 2
0.12 and s
= 0.3.
Coefficient of variation = (standard deviation / mean) * 100%
Dataset 1:
Standard deviation = 7 ; mean = 12
Coefficient of variation = (7 / 12 ) * 100% = 0.5833 = 58%
Dataset 2:
Standard deviation = 0.3 ; mean = 0.12
Coefficient of variation = (0.3 / 0.12) * 100% = 2.5 * 100% = 250
Hence dataset 2 varies the most with a greater value of variation Coefficient.

The measure of one side of a square is (s + 3) inches long. The pair of expressions which both represents the perimeter of this square is:

The third term of a geometric progression is 63/4 and the sixth term is 1701/32. Find the sum of the first 12 terms of the sequence.
Answer:
The sum of the first 12 terms of the sequence is 2703.673096
Step-by-step explanation:
The nth term of a geometric progression is a(n) = [tex]ar^{n-1}[/tex], where
a is the first termr is the common ratio between each two consecutive termsThe sum of n terms of the geometric progression is s(n) = [tex]\frac{a(r^{n}-1)}{r-1}[/tex]
∵ The third term of a geometric progression is [tex]\frac{63}{4}[/tex]
∴ a(3) = [tex]\frac{63}{4}[/tex]
∵ a(3) = ar²
→ Equate its two right sides
∴ ar² = [tex]\frac{63}{4}[/tex] ⇒ (1)
∵ The sixth term is [tex]\frac{1701}{32}[/tex]
∴ a(6) = [tex]\frac{1701}{32}[/tex]
∵ a(6) = a[tex]r^{5}[/tex]
→ Equate its two right sides
∴ a[tex]r^{5}[/tex] = [tex]\frac{1701}{32}[/tex] ⇒ (2)
→ Divide (2) by (1)
∴ r³ = [tex]\frac{27}{8}[/tex]
→ Take ∛ for both sides
∴ r = [tex]\frac{3}{2}[/tex] = 1.5
→ Substitute the value of r in (1) to find a
∵ a(1.5) = [tex]\frac{63}{4}[/tex]
∴ 1.5a = 15.75
→ Divide both sides by 1.5
∴ a = 10.5
→ Let us find the sum of the first 12 terms
∵ n = 12, a = 10.5, and r = 1.5
→ Substitute them in the rule of the sum above
∵ s(12) = [tex]\frac{10.5(1.5^{12}-1)}{1.5-1}[/tex]
∴ s(12) = 2703.673096
∴ The sum of the first 12 terms of the sequence is 2703.673096
Suppose scientists compared the wind speeds and barometric pressure readings of two severe storms over the Atlantic Ocean. For one of the storms, the barometric pressure was 1,000 mb (millibars), and the maximum wind speed was 100 kmh (kilometers per hour). The second had a barometric pressure of 960 mb and maximum wind speeds of 180 kmh. (a) Develop a rule that you could use to predict the wind speed given any barometric pressure.
Answer:
So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.
Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.
Slope= (180-100)
---------------- = -2
(960-1000)
Formula: y=-2(x-1000)+100
Part B: y=-2(980-1000)+100=140
140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.
Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.
Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

Step-by-step explanation:
m(x)=x2+4x n(x)=x
(mn)(x)=
A.) x2+4x(x)
B.) (x2+4x)(x)
Answer:
b is correct
Step-by-step explanation:
The product of the functions M(x) and n(x) is x³+ 4x².
To find the product of the two functions, M(x) = x² + 4x and n(x) = x, we need to multiply them together.
So, (mn)(x) = M(x) × n(x)
Substituting the given functions:
(mn)(x) = (x² + 4x) × x
Now, we can simplify the expression by applying the distributive property of multiplication:
(mn)(x) = x × x² + x × 4x
Simplifying further:
(mn)(x) = x³ + 4x²
Therefore, the product of the functions M(x) and n(x) is x³+ 4x².
