The specific heat shows that Substance Y has more atoms per gram than substance W.
Specific heat:
Specific heat is a property of a substance that describes how much heat energy is required to raise the temperature of a certain amount of that substance by one degree. It is typically measured in units of joules per gram per degree Celsius (J/g°C).
Different substances have different specific heats. For example, water has a relatively high specific heat of 4.18 J/g°C, which means that it takes a lot of heat energy to raise the temperature of water by one degree. This is why water is often used as a coolant or in air conditioning systems, as it can absorb a large amount of heat energy without experiencing a significant temperature change.
Therefore, the specific heat shows that Substance Y has more atoms per gram than substance W.

A corporate iued a bond with a face value of Php 2,000, a 6% coupon, and a 10-year maturity date. How much will the corporation pay to the bondholder?
The corporation will pay the bondholder a total of Php 1,200 + Php 2,000 = Php 3,200 over the life of the bond.
A bond's coupon is the annual interest payment that the bond issuer promises to pay to the bondholder. In this case, the bond has a face value of Php 2,000 and a 6% coupon, so the annual interest payment is 6% * Php 2,000 = Php 120.
The bond has a maturity date of 10 years, so the total interest payments to the bondholder over the life of the bond will be Php 120 * 10 = Php 1,200.
In addition to the interest payments, the bond issuer also promises to return the bondholder the face value of the bond at the maturity date. In this case, the face value of the bond is Php 2,000.
So, the corporation will pay the bondholder a total of Php 1,200 + Php 2,000 = Php 3,200 over the life of the bond.

what is the expected number of cards that need to be turned over in a regular 52 card deck in order to see the first ace
In a standard 52-card deck, 10.6 turns of the cards are anticipated before the first ace is seen.
What exactly is a ship's deck?A deck is a structure that covers a sea bed or a compartment permanently. The primary or top deck on a boat or ship is the horizontal support that acts as the hull's "roof," reinforcing it and providing the main working area.
An n-card deck will often need turning over (n+1)/(k+1) cards before the initial set of k notes can be seen. Given that there have been four aces and n=52, k=4, the solution is 53/5, which is 10.6.
The predicted count is therefore increased by 1/(k+1) for each non-target card, such as a card that wasn't an ace there in original question. Since there are n-k – anti cards, (n-k)/(k+1) is the anticipated group of non cards to appear prior to the initial target card. Because the initial target card increases the count by one, we may predict that (n-k)/(k+1) + 1 Equals (n+1)/(k+1).

If a coin is flipped four times, find the probability distribution for the number of heads. The correct option is (c) is Chart C.
In probability theory and statistics, a probability distribution is a mathematical function that gives the probability of occurrence of various possible outcomes of an experiment. This is a mathematical description of a random phenomenon in terms of sample space and event probabilities (a subset of the sample space).
For example, if X is used to denote the result of a coin toss ("experimental"), the probability distribution of X gives the value 0.5 (1 to 2 or 1/2) for X = table. and assume that: 0, 5 for X = tail (assuming the coin is fair). Examples of random phenomena are the weather conditions at a later date, the height of a randomly selected person, the proportion of boys in a school, or the results of a survey being conducted.
General Properties of Probability Distributions
Statisticians call variables that follow probability distributions random variables. The notation for a random variable that follows a particular probability distribution function is

question in a certain town in north america. the time of sunrise for any day of the year can be found using the equation where is the time in hours after midnight and is the number of the day in the year. to the nearest minute, when did the sun rise on december 25th, the 359th day of the year?
t = 4.9029 for Given the equation t = -0.0069d + 7.35, where t is the time of sunrise in hours after midnight and d is the number of the day in the year,
To find the time of sunrise on December 25th, the 359th day of the year, we need to substitute 359 for d in the equation.
t = -0.0069(359) + 7.35
t = -2.4471 + 7.35
t = 4.9029
This means that the time of sunrise on December 25th is 4.9029 hours after midnight. To convert this to minutes, we can multiply 4.9029 by 60 (since there are 60 minutes in an hour).
4.9029 x 60 = 294.174
So the sun rose on December 25th at 294.174 minutes after midnight, which is equivalent to 4 hours and 54 minutes (294 minutes) after midnight. To the nearest minute, the sun rose on December 25th at 4:54 AM.
As the moon moves in its orbit, its side where it gets illuminated by the Sun also changes.
On a full moon day, the moon rises at the time of sunset and sets at the time of sunrise the next day.

17297280 ways can the sites for the new stores be selected. This can be solved using the concept of probability.
What is probability?The word "probability" derives from the Latin word "probitatem," which means "credibility, likelihood," from the noun probabilis in the 14th century (see probable). The phrase was first used in a mathematical meaning in 1718.
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Given that,
14 different sites on which to locate 7 stores
For store 1, it can be placed on 14 sites.
Store 2 can be placed on 13 sites (since store 1 is already on site 1).
Store 3 can be placed on 12 sites and
so on until store 7 which has 8 sites.

4) To cook 10 cups of rice, Martha used 18 cups of water. If Martha cooks 12 cups of rice, how much water does she need?
Answer:
To cook 10 cups of rice, Martha used 18 cups of water. We know that this is a proportion of the amount of water needed to the amount of rice cooked:
10 cups of rice : 18 cups of water = x : y
We also know that x is the amount of water needed to cook 12 cups of rice.
To find out how much water Martha needs, we can keep the proportion and substitute the known value of x.
10 cups of rice : 18 cups of water = 12 cups of rice : y
We can cross multiply to get:
10 * y = 18 * 12
y = 18 * 12 / 10
y = 21.6 cups
Therefore, Martha needs 21.6 cups of water to cook 12 cups of rice.

a 342-inch pipe is cut into two pieces one piece is five times the length of the other. Find the lengths of the two pieces
Answer:
285 and 57Step-by-step explanation:
First, find the length of the longer pipe, which is stated to be 5 times longer than the shorter piece. Substitute the longer piece as b. Same for the shorter piece, but as a.
[tex]a + b = 342\\5b\:+\:? = 342\\a = 5b[/tex]
Why a is 5b is because a is the correspondent value to b since they are both substituted, in short words this means that a will be the equivalent of |5 × b - 342|
Next, we substitute the problem in a ruled equation. Think of it this way: There are 2 values in the equation. One has a value of 5 and the other has a value of one. Add those together, and you get 6, right? This will be important for our final answer.
[tex]6b\div 6 = 342\div 6\\b = 57[/tex]
Lastly, substitute a.
[tex]a + b = 342\\a + \bold{57} = 342\\a = \left(342 - 57\right)\\\\a = 285\\b = 57[/tex]

Answer:
108 cm
Step-by-step explanation:
You need to figure out the area of both triangles and then add them to the area of the rectangle. The area of the rectangle can be found like:
12x5=60.
Then, you need to find the are of the triangles. We are told the height of the hexagon is 13cm, and that the height of the rectangle is 5cm. So, the area of the height triangles is 13-5cm and to get the height of the original triangles we will do:
13-5=8/2=4.
Next, we need to find the area of the triangles. That is calculated using the formula a=(1/2)bh. The base is 12 cm (same as the bottom rectangle side) and the height, as found in the previous problem is 4cm. So, what we will do is:
a=(1/2)4*12=24.
The area of one triangle is 24, so we will add that to get the triangles combined area, to 48. The total area of the shape comes by adding all the areas of the shaped found inside it.
60+48=108. So the area of the hexagon is 108 cm.
