Ethan once heard that wearing colorful socks helped release your positive energy toward others. Being the scientist that he is, he decided to put the claim to the test by running a well-designed study. He had 18 people wearing colorful socks at an auditorium where the rest of the people were wearing white socks. After carefully designing, collecting, and analyzing his data, he found no statistically significant difference between his sample of 18 participants and the rest of the population he studied regarding positive energy. What should Ethan conclude regarding the null hypothesis
Answers
Answer:
The answer is "Choice A".
Step-by-step explanation:
Please find the complete question in the attachment file.
Throughout this question by acceptance of its zero hypotheses becomes equal to "the failure to accept the zero hypotheses." Its best answer is to refuse the null hypothesis or conclude how he had no effects on vibrant socks mostly on basis of this study, that's why the above given choice is correct.

Lamar needs to buy some pencils. Brand A has a pack of 18 pencils for 2.36 . Brand B has a pack of pencils 24 for 4.09 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answers
Answer:
The unit price of brant A and brand B is 0.1311 and 0.1704 and brand A would be better
Step-by-step explanation:
The computation of the unit price for each brand is shown below:
For brand A, the unit price is
= 2.36 ÷ 18 pencils
= 0.1311
For Brand b, the unit price is
= 4.09 ÷ 24
= 0.1704
So here as we can see that brand A would be better as it has less cost as compared with brand B

Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 24 units to the right of the vertex of the graph of g(x). Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=x2−24 and g(x)=x2
h(x)=x2+24 and g(x)=x2
h(x)=(x−24)2 and g(x)=x2
h(x)=(x+24)2 and g(x)=x2
Answers
Answer:
The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2
Step-by-step explanation:
Example: If we have q(x) = x^2 and its graph, moving the vertex of this graph 24 units to the right results in r(x) = (x - 24)^2.
The correct pair of functions is the third one: h(x)=(x−24)^2 and g(x)=x2
Note: the fourth pair is incorrect, because the " + " sign moves the graph of x^2 24 units to the left.

A carpenter is assigned the job of expanding a rectangular deck where the length is three times the width. The width of the deck is to be expanded by 8 feet and the length is to be expanded by the new width. If the area of the new rectangular deck is 240 ft larger than the area of the original deck, find the dimensions of the original deck.
Answers
Yo = original width of deck
Therefore:
Yo = (1/6)Xo
The original deck area is:
Ao = XoYo
Ao = Xo(1/6)Xo = (1/6)Xo2
The length of the new deck is 4ft longer than the original deck, or XN = Xo + 4, and the width is 2ft longer than the original, or YN = Yo + 2, and the new area of the deck is 56ft2 than the original area, or AN = Ao + 56.
Therefore: AN = XNYN
Ao + 56 = (Xo + 4)(Yo + 2)
(1/6)Xo2 + 56 = (Xo + 4)(1/6Xo + 2)
(1/6)Xo2 + 56 = (1/6)Xo2 + 2Xo + (4/6)Xo +8
56 = 2Xo + (2/3)Xo +8
56 - 8 = (2 + 2/3)Xo
48 = (6/3 + 2/3)Xo
48 = (8/3)Xo
48(3/8) = Xo
Xo = 18ft
Yo = (1/6)(18)
Yo = 3ft
Check: Ao = XoYo = (18)(3) = 54ft2
XN = Xo + 4 = 18 + 4 = 22ft
YN = Yo + 2 = 3 + 2 = 5ft
AN = (22)(5) = 110ft2
Ao + 56 = AN
54 + 56 = 110
110 = 110 check------->ANSWER: original length, Xo = 18ft
original width, Yo = 3ft

Can you guys help me with this please it suppose to use the synthetic substitution or the remainder theorem.
Answers

Answer:
(b) -36
Step-by-step explanation:
Synthetic division is often performed using a table of the kind shown in the attachment. The coefficients of f(x) are placed across the top, and the x-value to be evaluated is placed at the left. The rule for finding table entries is shown. (The first (left-most) number at the bottom is the leading coefficient of the polynomial.)
This table shows the remainder, which is f(-2), is -36.
__
The equation itself can be rewritten in "Horner form" to facilitate evaluation.
f(x) = (((-x +2)x -1)x +4)x +8
In this form, substituting for x and doing the evaluation is easier for mental arithmetic. You will notice that the contents of parentheses at each level match the bottom line of the synthetic division table.
f(-2) = (((-(-2) +2)(-2) -1)(-2) +4)(-2) +8
= (((4)(-2) -1)(-2) +4)(-2) +8
= ((-9)(-2) +4)(-2) +8
= (22)(-2) +8
= -36
f(-2) = -36 . . . . remainder from synthetic substitution
If two cylinders have the same base, and one cylinder has a height of 4 inches and a volume of 120 cubic inches, and the second cyclinder has 7 inches what's the volume of the second cylinder
Answers
Answer:
210 cubic inches
Step-by-step explanation:
The volume V of a cylinder is given as
V = πr^2h where r is the base radius and h is the height
If two cylinders have the same base, then their radii are the same
Given that one cylinder has a height of 4 inches and a volume of 120 cubic inches then
120 = πr^2 * 4
Divide both sides by 4
30 = πr^2
Given that the second cylinder has a height of 7 inches then the volume
V = πr^2 * 7
Recall that 30 = πr^2
V = 30* 7
= 210 cubic inches

The hypotenuse of a 30 -60 -90 triangle is 13cm. What is the length of the shorter leg?
Answers
Answer:
(13/2) cm
Step-by-step explanation:
The hypotenuse here is of length 13 cm. The shorter leg lies opposite to the 30° angle. Recall that the sine function is defined as
opposite side
sin Ф = -----------------------
hypotenuse
which, in this case, works out to:
opposite side
sin 30° = -----------------------
13 cm
and so the length of the opposite side (which is also the "shorter leg") is
shorter leg length = (13 cm)(sin 30°) = (13 cm)(1/2) = (13/2) cm
