Answer:
[tex]Probability = \frac{1}{20}[/tex]
Step-by-step explanation:
Given
[tex]People = 6[/tex]
[tex]Selection = 3[/tex]
Required
Determine the probability of selecting the oldest 3
First, we need to determine the total possible selection.
Since it's a selection, we make use of combination as follows:
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
In this case:
[tex]n = 6[/tex]
[tex]r = 3[/tex]
So:
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
[tex]^6C_3 = \frac{6!}{(6-3)!3!}[/tex]
[tex]^6C_3 = \frac{6!}{3!3!}[/tex]
[tex]^6C_3 = \frac{6*5*4*3!}{3!3*2*1}[/tex]
[tex]^6C_3 = \frac{6*5*4}{3*2*1}[/tex]
[tex]^6C_3 = \frac{5*4}{1}[/tex]
[tex]^6C_3 = 20[/tex]
In the combination, there can be only 1 set of oldest people.
So:
[tex]Probability = \frac{1}{20}[/tex]

Which is greater 3.75 3.750
Answer:
None
Step-by-step explanation:
They are the same number
They are equal and neither is greater than the other.
In the decimal number system, trailing zeros after the decimal point do not affect the value of the number. They are considered insignificant and are not used to determine the magnitude or comparison of the numbers.
When comparing 3.75 and 3.750, it's important to understand that they represent the same value. The digits after the decimal point in both numbers are identical. The presence of the trailing zeros in 3.750 does not change the actual value of the number; it's just a different representation.
To illustrate this, let's consider the number line:
3.749 < 3.7499 < 3.74999 < 3.75 = 3.750 < 3.7501 < 3.75001 < 3.751
As you can see, both 3.75 and 3.750 lie at the same point on the number line, indicating that they are equal in value. The trailing zeros in 3.750 are insignificant and do not affect the magnitude or comparison of the numbers.
Therefore, in terms of their numerical value, 3.75 and 3.750 are equivalent and not different from each other.

Jason and Nick were biking at a constant speed of 10 seconds, Jason biked 30 meters and Nick biked 45 meters. Who was biking at a faster rate?
Answer:
Nick
Step-by-step explanation:
Find their rates by dividing the number of meters they biked by 10:
Jason:
30/10
= 3 meters/sec
Nick:
45/10
= 4.5 meters/sec
So, since 4.5 is bigger than 3, Nick was biking at a faster rate.

The density of a certain material is such that it weighs 8 ounces for every 3 gallons of volume. Express this density in grams per cubic meter. Round your answer to the nearest whole number.
Answer:
≈19974 grams per cubic meter.
The required density in grams per cubic meter is 19895 g / m³.
Given that,
The density of a certain material is such that it weighs 8 ounces for every 3 gallons of volume. Express this density in grams per cubic meter, round your answer to the nearest whole number, is to be determined
Volume is defined as the ratio of the mass of an object to its density. And that space is occupied by an object in the space.
Here,
1 gallon = 0.0038 m³
3 gallon = 0.0114 m³
Volume = 0.0114 m³
Mass =
1 ounce = 28.35 g
8 ounce = 8 * 28.35
8 ounce = 226.8 g
Mass = 226.8 g
density = mass / volume
= 226.7 / 0.0114
≈ 19895 g / m³
Thus, the required density in grams per cubic meter is 19895 g / m³.

In a race, a red car starts 1 km behind a blue car. The red car is traveling at 55 km per hour, while the blue one
is traveling at 40 km per hour. How long will it take for red car to overtake the blue one?
Answer:
The red car will need 4 minutes to overtake the blue car.
Step-by-step explanation:
Constant Speed Motion
When an object travels equal distances in equal times, it's said to have a constant speed.
The speed is the ratio between the distance d and time t.
[tex]\displaystyle v=\frac{d}{t}[/tex]
If the speed is known, we can solve the equation for d:
d = v.t
Similarly, the time is calculated as:
[tex]\displaystyle t=\frac{d}{v}[/tex]
In the race, the red car starts 1 Km behind a blue car. The red car travels at 55 Km/h and the blue car travels at 40 Km/h. Since the red car moves faster, it will eventually overtake the blue car.
The difference in speeds between both cars is 55 - 40 = 15 Km/h.
That relative speed makes both cars to get closer until the head start is overtaken. Thus, the time needed for both cars to meet is:
[tex]\displaystyle t=\frac{1~Km}{15~Km/h}[/tex]
t = 0.0667 hours.
Computing in minutes:
[tex]\displaystyle t=\frac{1~Km}{15~Km/h}*60[/tex]
t = 4 minutes.
The red car will need 4 minutes to overtake the blue car.

Which two processes are destructive forces that occur during sedimentary rock formation?
cementation and compaction
compaction and deposition
deposition and weathering
weathering and erosion
Answer:
D. Weathering and erosionStep-by-step explanation:
Sedimentary rocks are formed from sediments and deposits particles of various types, forms and sizes that are transported by air, wind and water, and then subjected to chemical processes to become rocks. These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys and lakes (and any other type of body of water)In this sense, the processes that contribute to the formation of a sedimentary rock are weathering and erosion.Answer:
(D)
Step-by-step explanation:
Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth’s surface they begin the long slow but relentless process of becoming sedimentary rock.All rocks are subject to weathering. Weathering is anything that breaks the rocks into smaller pieces or sediments. This can happen by the forces of like wind, rain, and freezing water.The sediments that form from these actions are often carried to other places by the wind, running water, and gravity. As these forces lose energy the sediments settle out of the air or water. As the settling takes place the rock fragments are graded by size. The larger heavier pieces settle out first. The smallest fragments travel farther and settle out last. This process of settling out is called deposition.The combination of weathering and movement of the resulting sediments is called erosion.Lithification is the changing of sediments into rock. There are two processes involved in this change. They are compaction and cementation.Compaction occurs after the sediments have been deposited. The weight of the sediments squeezes the particles together. As more and more sediments are deposited the weight on the sediments below increases. Waterborne sediments become so tightly squeezed together that most of the water is pushed out. Cementation happens as dissolved minerals become deposited in the spaces between the sediments. These minerals act as glue or cement to bind the sediments together.
Craig went bowling with $25 to spend. He rented shoes for $5.00 and paid $4.00 for each game. What was the greatest number of games Craig could have played?
Answer:
5 games
Step-by-step explanation:
Answer:
6 games.
Step-by-step explanation:
25 - 5 = 20 {We subtract 5 from 25 because craig has 25$ to spend, and are renting shoes for 5$. The rest of the money is going towards the cost PER game, shown in step 2.}
20 divided by 4 = 6. {4$ is the cost of each game. Therefore, divide 20 by 4.}

6. Solve the problem. A carousel has a radius of 18 feet and takes 31
seconds to make one complete revolution. What is the linear speed of
the carousel at its outside edge? Express the answer in feet per second.
If necessary, round the answer to two decimal places.
Answer:
v = 3.64 ft/s
Step-by-step explanation:
Given that,
Radius of a carousel, r = 18 feet
It takes 31 seconds to complete revolution.
We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.
d = 2πr
d = 2π × 18 = 113.09 feet
Let v is the linear speed. It can be given by :
[tex]v=\dfrac{D}{t}\\\\v=\dfrac{113.09}{31}\\\\v=3.64\ ft/s[/tex]
So, the linear speed of the carousel is 3.64 ft/s.
