Answer:
the number of sponges per package bought be 32.5
Step-by-step explanation:
Let us assume the number of sponges per package be x
So the number of packages he bought be x - 14
And, the overall he bought 51 sponges
So
the number of packages of sponges did roger buy is
x + x - 14 = 51
2x = 51 + 14
2x = 65
x = 32.5
So the number of sponges per package bought be 32.5

interference is a property of a. light waves. b. sound waves. c. water waves. d. all of these e. none of these
Interference is a property of ALL the given wave options, which are light waves, sound waves, and water waves.
Interference is the phenomenon of two or more waves combining to form a resultant wave of greater, lower, or the same amplitude.
When two waves meet at the same point at the same time, they either combine constructively (resulting in the formation of a wave of greater amplitude) or destructively (resulting in the formation of a wave of lower amplitude).
For instance, when two sound waves or light waves meet, they create a resultant wave whose amplitude is equal to the sum of the two original waves.
This is known as constructive interference.
On the other hand, when two waves meet and their amplitudes are in opposite directions, they produce a resultant wave whose amplitude is equal to the difference between the two waves.
This is known as destructive interference.

Recall the following statement from Worksheet 11: Theorem 1. If G = (V, E) is a simple graph (no loops or multi-edges) with |V] = n > 3 vertices, and each pair of vertices a, b eV with a, b distinct and non-adjacent satisfies deg(a) + deg(6) > n, then G has a Hamilton cycle. (a) Using this fact, or otherwise, prove or disprove: Every connected undirected graph having degree sequence 2, 2, 4, 4, 6 has a Hamilton cycle. (b) The statement: Every connected undirected graph having degree sequence 2, 2, 4, 4,6 has a Hamilton cycle is A. True B. False.
The statement "Every connected undirected graph having degree sequence 2, 2, 4, 4, 6 has a Hamilton cycle" is false.
To disprove the statement, we need to provide a counterexample of a connected undirected graph with the degree sequence 2, 2, 4, 4, 6 that does not have a Hamilton cycle.
Consider a graph with five vertices labeled A, B, C, D, and E. Connect A and B with an edge, A and C with an edge, B and D with an edge, B and E with an edge, and C and D with an edge. Additionally, connect C and E with an edge, and D and E with an edge. This graph satisfies the given degree sequence.
However, this graph does not have a Hamilton cycle. A Hamilton cycle is a cycle in a graph that visits every vertex exactly once and returns to the starting vertex. In the provided graph, there is no way to construct such a cycle, as it is not possible to visit all vertices exactly once and return to the starting vertex.
Therefore, the statement "Every connected undirected graph having degree sequence 2, 2, 4, 4, 6 has a Hamilton cycle" is false (option B).

Sam is practising free-throws in basketball. She has a 4/5 chance of scoring each time she shoots from the free-throw line. (You should assume that the probability of scoring for each shot is independent of the result of other attempts.) What is the expected value of the number of free-throws that Sam will score before her first miss? 4/25 What is the variance of the number of free-throws that Sam will score before her first miss?
Sam has a 4/5 expected value of scoring each time she shoots from the free-throw line.
How is this so?
This means that the probability of her missing her first shot is 1/5. The expected value of the number of free-throws that Sam will score before her first miss is therefore 1/(1/5) = 5.
The variance of the number of free-throws that Sam will score before her first miss is (1−p)/p²
, where p is the probability of success.
In this case, p=4/5, so the variance is (1−4/5)/(4/5)²

The odds against drawing a face card out of a deck are 9:4. What is the probability of drawing a face card?
The probability of drawing a face card from a deck is 3/13 or approximately 0.23.
The odds against an event is defined as the ratio of the number of ways the event doesn't occur to the number of ways it occurs. In this case, the odds against drawing a face card from a deck are 9:4. So, there are 9 ways to not draw a face card and 4 ways to draw a face card.
The total number of cards in a deck is 52, and there are 12 face cards (4 jacks, 4 queens, and 4 kings). Therefore, the probability of drawing a face card is:
P(face card) = number of face cards/total number of cards = 12/52 = 3/13
We can check that this probability satisfies the given odds against:
9/4 = 9/(9+4) = 9/13
1 - P(face card) = 1 - 3/13 = 10/13
The odds against drawing a face card is the same as the probability of not drawing a face card, which is 10/13. Therefore, the odds in favour of drawing a face card can be calculated as:
odds in favour= (3/13)/(10/13) = 3/10

Find the curvature k(t) of the curve r(t) = (-2 sin t)i + (-2 sin t)j + (-1 cost)k = 2sqrt2/(sqrt(8cost^2t+sin^2t)^(3/2))
The curvature k(t) of the Eequation r(t) = (-2sint) i + (-2sint) j + (-cost) k will be [tex]\frac{2\sqrt{2} }{(8cos^2t + sin^2t)^{3/2}}[/tex]
Given r(t) = (-2sint) i + (-2sint) j + (-cost) k
We can clearly see that r(t) is a vector equation of t.
If r(t): R→R³ is a vector-valued function of a real variable with independent scalar output variables x, y & z
where, r(t) = {x, y, z}
Where x = (-2sint) , y = -2sint and z = -cost
We know that the curvature to be
|| r'(t) X r"(t) || / ||r'(t)||³
This implies we need to find the determinant of the cross product of the derivative and double derivative of the equation r(t) for the numerator
r'(t) = (-2cost) i + (-2cost) j + (sint) k
r"(t) = (2sint) i + (2sint) j + (cost) k
hence we get || r'(t) X r"(t) || to be
[tex]\left|\begin{array}{ccc}i&j&k\\-2cost&-2cost&sint\\2sint&2sint&cost\end{array}\right|[/tex]
[tex]= \left|\begin{array}{ccc}-2cost&sint\\2sint&cost\end{array}\right| i - \left|\begin{array}{ccc}-2cost&sint\\2sint&cost\end{array}\right|j + \left|\begin{array}{ccc}-2cost&-2cost\\2sint&2sint\end{array}\right|k[/tex]
= -2i + 2j
Hence the magnitude will be
√(2² + 2²)
= 2√2 units
magnitude of r'(t) is
[tex]\sqrt{(2sint)^2 + (2sint)^2 + (cost)^2}[/tex]
= [tex]\sqrt{8cos^2t + sin^2t}[/tex]
Hence we get the curvature to be
[tex]\frac{2\sqrt{2} }{(\sqrt{8cos^2t + sin^2t})^3}[/tex]
simplifying this will give us
[tex]\frac{2\sqrt{2} }{(8cos^2t + sin^2t)^{3/2}}[/tex]
Hence the curvature k(t) will be [tex]\frac{2\sqrt{2} }{(8cos^2t + sin^2t)^{3/2}}[/tex]

Calculate each unit price. Determine which is the best buy.
$1.25 for 6 oz.
$1.33 for 8 oz.
$1.50 for 12 oz.
$2.05 for 16 oz.
Answer:
1.50 for 12 ounces would be the best buy.
Step-by-step explanation:
We can calculate the unit price by dividing the price the the amount. In this case, we use ounces as our amount. Based on the calculations below, the best buy would be the 1.50 for 12 ounces as it has the lowest unit price.
1.25/6 = 0.208
1.33/8 = 0.166
1.50/12 = 0.125
2.05/16 = 0.128
