Answer:
Nominal.
Step-by-step explanation:
The option that is NOT a level of measurement is qualitative.
With qualitative, numbers are not assigned to the measurement.
A level of measurement classifies and relates values to variables. Four levels of measurement have been identified as nominal, ordinal, interval, and ratio.
Ordinal can be quantitative or qualitative, while interval and ratio are always quantitative, and nominal has non-quantitative values assigned as measurements.
Thus, qualitative is not a recognized level of measurement.

Find the perimeter of the following square.
A. 1 inch
B. 2 inches
C. 3 inches
D. 4 inches
Answer:
D
Step-by-step explanation:
the perimeter of a shape is the sum of it's sides
in a square all sides have the same length
here all sides are 1 inch
so 1+1+1+1 = 4 inches which is D

endamount - startamount divided by number of days.
(237-27) / 14 = 15
Answer:
237 - 27 = 210 (she already had 27 to start, so subtract that from the total)
210 ÷ 14 = 15 (divide by 14 because there are 14 days in two weeks)
so she bought 15 stickers each day
Find all of the real and imaginary solutions of x^3+8=0
Answer:
[tex]x=-2, \:1+\sqrt{3}i,\: 1-\sqrt{3} i[/tex]
Step-by-step explanation:
[tex]x^3+8=0,\\x^3=-8,\\\mathrm{For\:}x\in \mathrm{R}, x=-2[/tex]
Real solutions ([tex]x \in \mathrm{R}[/tex]): [tex]x=-2[/tex]
However, recall that [tex](\frac{-1\pm\sqrt{3}i}{2})^3=1[/tex].
Therefore:
[tex]\frac{-1\pm\sqrt{3}i}{2}\cdot -2=-2[/tex].
Thus, for [tex]x^3=-8,\: x\notin \mathrm{R}[/tex]:
[tex]x=1\pm\sqrt{3}i[/tex].
Therefore, the real and nonreal solutions of [tex]x^3+8=0[/tex] are [tex]\fbox{$-2, \:1+\sqrt{3}i,\: 1-\sqrt{3}i$}[/tex].
Answer:
-2, 1 +/- i*sqrt(3)
(3 solutions)
Step-by-step explanation:
Because the left side is in the form a^3+b^3, we can factor it as (a+b)(a^2-ab+b^2) (good formula to remember)
So we have
(x+2)(x^2-2x+4)
We can see one value already
x+2 = 0
x = -2
now we solve for
x^2-2x+4 = 0
We can use the quadratic formula, and see that the determinant is negative (2^2-4*1*4 < 0)
Therefore we have two imaginary solutions
(-(-2) +/- sqrt(2^2-4*1*4))/)2*1) = (2 +/- sqrt(-12))/2 = (2 +/- 2sqrt(-3))/2 = 1+/- sqrt(-3) = 1 +/- i*sqrt(3)
Solve the triangle given that a=19 b=16, c=11.
Answer:
The angles of the triangle are approximately 87.395º, 57.271º and 35.334º.
Step-by-step explanation:
From statement we know all sides of the triangle ([tex]a[/tex], [tex]b[/tex], [tex]c[/tex]), but all angles are unknown ([tex]A[/tex], [tex]B[/tex], [tex]C[/tex]). (Please notice that angles with upper case letters represent the angle opposite to the side with the same letter but in lower case) From Geometry it is given that sum of internal angles of triangles equal 180º, we can obtain the missing information by using Law of Cosine twice and this property mentioned above.
If we know that [tex]a = 19[/tex], [tex]b = 16[/tex] and [tex]c = 11[/tex], then the missing angles are, respectively:
Angle A
[tex]a^{2} = b^{2}+c^{2}-2\cdot b\cdot c \cdot \cos A[/tex] (1)
[tex]A = \cos^{-1}\left(\frac{b^{2}+c^{2}-a^{2}}{2\cdot b\cdot c} \right)[/tex]
[tex]A = \cos^{-1}\left[\frac{16^{2}+11^{2}-19^{2}}{2\cdot (16)\cdot (11)} \right][/tex]
[tex]A \approx 87.395^{\circ}[/tex]
Angle B
[tex]b^{2} = a^{2}+c^{2}-2\cdot a\cdot c \cdot \cos B[/tex] (2)
[tex]B = \cos^{-1}\left(\frac{a^{2}+c^{2}-b^{2}}{2\cdot a\cdot c} \right)[/tex]
[tex]B = \cos^{-1}\left[\frac{19^{2}+11^{2}-16^{2}}{2\cdot (19)\cdot (11)} \right][/tex]
[tex]B\approx 57.271^{\circ}[/tex]
Angle C
[tex]C = 180^{\circ}-A-B[/tex]
[tex]C = 180^{\circ}-87.395^{\circ}-57.271^{\circ}[/tex]
[tex]C = 35.334^{\circ}[/tex]
The angles of the triangle are approximately 87.395º, 57.271º and 35.334º.

What is the product of the radical expression?
(7- sqrt7)(-6 + sqrt7)
Given:
The expression is
[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]
To find:
The product of the radical expression.
Solution:
We have,
[tex](7-\sqrt{7})(-6+\sqrt{7})[/tex]
Using distributive propertry, we get
[tex]=(7)(-6)+(7)(\sqrt{7})+(-\sqrt{7})(-6)+(-\sqrt{7})(\sqrt{7})[/tex]
[tex]=-42+7\sqrt{7}+6\sqrt{7}-7[/tex]
On combining like term, we get
[tex]=(-42+7)+(7\sqrt{7}+6\sqrt{7})[/tex]
[tex]=-49+13\sqrt{7}[/tex]
Therefore, the product of the given radical expression is [tex]-49+13\sqrt{7}[/tex].

Reaner Recycling collected 7/4 ton of aluminum last Saturday. If 7/8 ton of aluminum can be shredded each day, how many days will it take to process what was collected on Saturday?
help me please it is hard
Answer:
2 days
Step-by-step explanation:
You would have to change 7/4 to have the same common denominator as 7/8, which is 8. 7/4 is equal to 14/8, or 1 6/8. Then you would subtract 1 6/8 by 7/8. What would be left would be 7/8. And of course, 7/8 minus 7/8 would be 0.

If you draw a card with a value of four or less from a standard deck of cards, I will pay you $162. If not, you pay me $45. (Aces are considered the highest card in the deck.) Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
the expected value of the proposition is 2.77
Step-by-step explanation:
The computation of the expected value of the proposition
= 162p - 45(1 - p)
= 162 × 12 ÷ 52 - 45 × (1 - 12 ÷ 52)
= 2.77
Hence, the expected value of the proposition is 2.77
So we simply do the above calculation so that the expected value could come
