The local tide measurement data contradict the satellite data because the number of decreasing local sea level trends is greater than the number of increasing local sea level trends. So correct option is C.
Describe Measuring of tides?Measuring tides involves observing and recording changes in the water level of oceans, seas, and other bodies of water over time. Tides are caused by the gravitational pull of the moon and sun on the Earth's water, which results in a rhythmic rise and fall of water levels.
Tide measurements are important for a variety of reasons, including understanding ocean circulation, predicting flooding and storm surges, and planning shipping routes. Tidal data is also used in climate research, as changes in sea level can indicate long-term climate trends.
The local tide measurement data contradict the satellite data because the number of decreasing local sea level trends is greater than the number of increasing local sea level trends.
The measurement is done because the land surfaces are dynamic with some locations rising or sinking relative to sea level changes are different across world coasts.
Therefore, the Option C is correct.

Rewrite as equivalent rational expressions with denominator (3m−4)(m+8)(m−7):
63m2+20m−32,3m3m2−25m+28
The first rational expression is 63m²+20m−32. To rewrite this with a common denominator of (3m−4)(m+8)(m−7), first we need to find the LCD (Lowest Common Denominator) of both terms. So, we need to multiply each numerator and denominator of the first rational expression by (3m−4)(m+8)(m−7).
In the numerator, we need to multiply 63m² by (3m−4)(m+8)(m−7):
63m² × (3m−4)(m+8)(m−7) = 63m³ - 224m² + 784m - 504
In the denominator, we need to multiply 1 by (3m−4)(m+8)(m−7):
1 × (3m−4)(m+8)(m−7) = 3m³ - 12m² + 24m - 16
Therefore, the rewritten rational expression is:
63m³ - 224m² + 784m - 504/3m³ - 12m² + 24m - 16
The second rational expression is 3m³m²−25m+28. To rewrite this with a common denominator of (3m−4)(m+8)(m−7), we first need to find

b) The proportion of cartons with less than 1.15 broken eggs is 0.60
c) The answer is B)This computation of the mean is incorrect because it does not take into account that the number of broken eggs are not all equally like.
(a) Hy = 0.67, which means that on average, there are 0.67 broken eggs per carton.
Hy = (0*0.60 + 1*0.20 + 2*0.15 + 3*0.03 + 4*0.02)/1

(b) The proportion of cartons with less than 0.67 broken eggs is 0.60 which is probability of 0 broken eggs.. This may be surprising as the probability of having less than 0.67 broken eggs is only 0.60, but this is due to the fact that the distribution is skewed towards higher values.
(c) Hy is not equal to the simple average of 0, 1, 2, 3, and 4 because the distribution is not symmetrical. The probabilities are weighted towards higher values, which increases the mean. Additionally, the value of zero should be included in the calculation, as it represents a possible outcome.

Sanborn Inc. is a new manufacturing company founded on February 2, 2012. The company had to choose between the LIFO and FIFO methods for its inventory. Inventory costs were rising during 2012, so the company decided to use the LIFO method. Which of the following items would be decreased by the choice of LIFO (compared to what would have happened if they chose to use FIFO)? (check all that apply)
Answer:
Step-by-step explanation:
By choosing the LIFO method for inventory, the following items would be decreased (compared to what would have happened if they chose to use FIFO):
Net income
Taxes payable
Total assets
Owner's equity
This is because the LIFO method results in higher cost of goods sold and lower ending inventory, which in turn decreases net income and taxes payable. Lower ending inventory also decreases total assets and owner's equity.
The items that would be decreased by the choice of LIFO (compared to what would have happened if they chose to use FIFO) are Ending inventory and Net profit
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
Inventory costs in 2012 were rising
Now,
LIFO stands for last-in, first-out, and FIFO stands for first-in, first-out. These are two ways of assigning costs to the units of inventory that you sell. FIFO assumes that you sell the oldest units first, while LIFO assumes that you sell the newest units first1.
The choice of LIFO or FIFO has implications on a company’s financial statements as this decision impacts the value of inventory, cost of goods sold, and net profit2. If inventory costs are rising during a period, then LIFO will result in a lower value of ending inventory, a higher cost of goods sold, and a lower net profit compared to FIFO1.
Therefore, by unitary method the answer will be Ending inventory and Net profit

find the area of a circle with a circumference of 50.24 50.24start color #11accd, 50, point, 24, end color #11accd units.
Answer:
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Solving for the radius, we have:
r = C/(2π) = 50.24/(2π) ≈ 8
So the radius of the circle is approximately 8 units.
The formula for the area of a circle is A = πr^2, so we have:
A = π(8)^2 = 64π ≈ 201.06
Therefore, the area of the circle is approximately 201.06 square units.

Where F_pivot is the magnitude of the force exerted on the pivot point.
What are perpendicular lines?
Perpendicular lines are lines that intersect at a right angle (90 degrees). In other words, if you draw a line perpendicular to another line, the two lines will form four right angles at the point where they intersect.
(a) The torque applied by the adult rider (on the left) can be calculated as the product of the force applied by the rider and the perpendicular distance from the pivot to the force. Let F_a be the force applied by the adult rider and let r_a be the perpendicular distance from the pivot to the force. Then, the torque applied by the adult rider is:
τ_a = F_a * r_a
The perpendicular distance r_a can be calculated using the Pythagorean theorem:
r_a = sqrt((L/2 - d)^2 + Xoffset^2)
Therefore, the torque applied by the adult rider is:
τ_a = F_a * sqrt((L/2 - d)^2 + Xoffset^2)
(b) Similarly, the torque applied by the child rider (on the right) can be calculated as:
τ_c = F_c * sqrt((L/2 + d)^2 + Xoffset^2)
where F_c is the force applied by the child rider and r_c is the perpendicular distance from the pivot to the force, which can be calculated using the Pythagorean theorem.
(c) The torque applied by the board can be calculated as the sum of the torques applied by the two riders:
τ_b = τ_a + τ_c
Substituting the expressions for τ_a and τ_c, we get:
τ_b = F_a * sqrt((L/2 - d)^2 + Xoffset^2) + F_c * sqrt((L/2 + d)^2 + Xoffset^2)
(d) To determine the distance d in terms of given quantities and variables, we can use the condition for static equilibrium, which requires that the sum of the torques about the pivot point is zero:
τ_a + τ_c = 0
Substituting the expressions for τ_a and τ_c and simplifying, we get:
F_a * (L/2 - d) = F_c * (L/2 + d)
Solving for d, we get:
d = (F_a/F_c - 1) * L/4
Substituting F_a = Mg and F_c = mg, where M is the mass of the adult rider, m is the mass of the child rider, and g is the acceleration due to gravity, we get:
d = (M/m - 1) * L/4
(e) The magnitude of the force exerted on the pivot point by the see-saw while in use can be calculated using the condition for static equilibrium, which requires that the sum of the forces in the vertical direction is zero:
F_a + F_c = Mg + mg
Substituting F_a = Mg and F_c = mg, we get:
F_pivot = Mg + mg
Therefore, where F_pivot is the magnitude of the force exerted on the pivot point.

b) Future value = P(1 + RT) = 800(1 + 0.015 x 5) = $870
Total time of loan = 6 months
Phyllis pays $200 two months into the loan, so she still owes $800 for the remaining 4 months.
Simple interest = PRT/100 = (800 x 2 x 4)/100 = $64

Let X and Y be independent random variables, uniformly distributed in the interval [0, 1 Find the CDF and the PDF of X-Y
Let X and Y be independent random variables, uniformly distributed in the interval [0, 1 ]. The CDF of X - Y is FZ(z) = (1/2)(1+z)^2 for -1 ≤ z ≤ 0, 1 - (1/2)(1-z)^2 for 0 ≤ z ≤ 1, 0 for z < -1 or z > 1. The PDF of X - Y is fZ(z) = z + 1 for -1 < z < 0, 1 - z for 0 < z < 1, 0 otherwise.
To find the CDF of X - Y, we first note that the range of X - Y is [0, 1]. Let Z = X - Y, then:
FZ(z) = P(Z ≤ z) = P(X - Y ≤ z)
We can write this as an integral over the joint distribution of X and Y:
FZ(z) = ∫∫[X - Y ≤ z] fXY(x, y) dx dy
Since X and Y are independent, the joint distribution is simply the product of their marginal distributions:
fXY(x, y) = fX(x) fY(y) = 1 * 1 = 1
for 0 ≤ x, y ≤ 1.
Thus, we have:
FZ(z) = ∫∫[X - Y ≤ z] dx dy
= ∫∫[Y ≤ X - z] dx dy
= ∫0^1 ∫0^(x-z) 1 dy dx + ∫0^1 ∫(x-z)^1 1 dy dx
= ∫0^(1+z) (1-z) dx
= (1/2)(1+z)^2 for -1 ≤ z ≤ 0
= 1 - (1/2)(1-z)^2 for 0 ≤ z ≤ 1
Therefore, the CDF of X - Y is:
FZ(z) =
(1/2)(1+z)^2 for -1 ≤ z ≤ 0
1 - (1/2)(1-z)^2 for 0 ≤ z ≤ 1
0 for z < -1 or z > 1
To find the PDF of X - Y, we differentiate the CDF:
fZ(z) = dFZ(z)/dz =
z + 1 for -1 < z < 0
1 - z for 0 < z < 1
0 otherwise
Therefore, the PDF of X - Y is:
fZ(z) =
z + 1 for -1 < z < 0
1 - z for 0 < z < 1
0 otherwise

One store had a 40% off sale. Another store had a 1/3 off sale. Which one had a better deal? How much better was it?
Answer:
The store with a 40% off sale.
Step-by-step explanation:
Since 1/3 of 100% is approximate, 33.4% and 40% will obviously be better. The 40% off sale is better by approximately 6.6%.
At Snobby Girls School, 65% of the girls are Clothes Ponies (C), 50% are Makeup Missies (M) and 30% are both. A girl from SCS is
chosen at random.
a) What is the probability she is a C?
b) What is the probability she is an M?
c) What is the probability she is both a C and an M?
d) If the chosen girl is an M, what is the probability she is also a C?
e) Are the two events C and M independent? Why or why not?
In response to the stated question, we may respond that Given that she is an M, the probability that the chosen female is both a M and a C is 0.6.
What is probability?Probabilistic theory is a branch of mathematics that calculates the likelihood of an event or proposition occurring or being true. A risk is a number between 0 and 1, with 1 indicating certainty and a probability of around 0 indicating how probable an event appears to be to occur. Probability is a mathematical term for the likelihood or likelihood that a certain event will occur. Probabilities can also be expressed as numbers ranging from 0 to 1 or as percentages ranging from 0% to 100%. In relation to all other outcomes, the ratio of occurrences among equally likely alternatives that result in a certain event.
a) The girl has a 0.65 chance of being a Clothes Pony (C).
b) The girl has a 50% chance of being a Makeup Missie (M).
c) The girl has a 0.30 chance of being both a Clothing Pony and a Makeup Missie.
d) Using the conditional probability formula, we can calculate the likelihood that the chosen female is both a M and a C provided that she is a M:
P(C|M) = P(C and M) divided by P (M)
Part (c) tells us that P(C and M) = 0.30, while Part (b) tells us that P(M) = 0.50. Therefore:
P(C|M) = 0.30 / 0.50 = 0.6
Given that she is an M, the likelihood that the chosen female is both a M and a C is 0.6.

The breadth of a rectangular playground is 5m shorter than its length. If its perimeter is 130m,find ids length and breadth.
Answer:
Length is 35 m and breadth is 30 mStep-by-step explanation:
Given,
The breadth of a rectangular playground is 5m shorter than its length.Perimeter is 130 mLet length be x and breadth (x - 5).
Perimeter of rectangle is calculated by :
[tex] \: \: \boxed{ \pmb{ \sf{Perimeter_{(rectangle)} = 2(l + b)}}} \\ [/tex]
On substituting the values we get :
[tex]\dashrightarrow \: \: 130 = 2(x + x - 5) \\ [/tex]
[tex]\dashrightarrow \: \: 130 = 2(2x - 5) \\ [/tex]
[tex]\dashrightarrow \: \dfrac{130}{2} = (2x - 5) \\ [/tex]
[tex]\dashrightarrow \: \: 65 = 2x - 5 \\ [/tex]
[tex]\dashrightarrow \: \: 65 + 5 = 2x \\ [/tex]
[tex]\dashrightarrow \: \: 70 = 2x \\ [/tex]
[tex]\dashrightarrow \: \: \frac{70}{2} = x \\ [/tex]
[tex]\dashrightarrow \: \: 35 = x \\ [/tex]
Hence,
Length = x = 35 m.Breadth = x -5 = (35 -5) = 30 mgiven :√9+25 : π-4 : ³√-27 : 2÷3 : 18÷2 : √-27

show that if we try to prove this inequality using mathematical induction, the basis step works, but the inductive step fails.
We show that at n = 1 the basis step works, but the inductive step fails.
Let consider the Inequality
[tex]\frac{1}{2}\cdot\frac{3}{4}\dots\dots\frac{2n-1}{2n} < \frac{1}{\sqrt{3n}}[/tex]
We must demonstrate that while the fundamental step of mathematical induction proves the aforementioned inequality, the inductive step does not.
Mathematical induction is a method of proof used in mathematics to prove that a statement is true for all natural numbers.
It involves proving that a statement holds true for a base case (typically zero or one), and then proving that, if it holds true for any given natural number, it must also hold true for the next natural number.
This process is repeated until the statement has been shown to be true for all natural numbers.
Basic Step: n = 1
1/2 < 1/√3, which is true.
Hence we proved that at n = 1 the basic steps of mathematical induction works.

A Triangle has a height that is half of 28 yards and an area of 56 yards^2. What is the length of the base of the trangle?
The length of the base of the triangle is 8 yards.
What is area of a triangle?The formula for calculating a triangle's area is
A = 1/2 * base * height,
where A represents the triangle's area, base its base length, and height its height measured perpendicularly from base to top.
Given that, height of triangle is half of 28 yards and an area of 56 sq. yards.
The area of triangle is given as:
A = 1/2 * base * height
Substitute the value of h = 1/2 (28) = 14 yards, and area = 56.
56 = 1/2 * base * 14
base = 56(2) / 14
base = 8 yards
Hence, the length of the base of the triangle is 8 yards.
