(adapted from Ross, 2.31) Three countries (the Land of Fire, the Land of Wind, and the Land of Earth) each make a 3 person team. Each team consists of three ninjas, each of a different rank: one genin junior ninja, one journeyman ninja, and one elite ninja.
(a) If a ninja is chosen at random from each of the three different countries, what is the probability of selecting a complete team? (A complete team here is a group consisting of three ninjas, each ninja of a different rank).
(b) If a ninja is chosen at random from each of the three different countries, what is the probability that all 3 ninjas selected have the same rank?
Answer:
The answer is "[tex]\frac{2}{9} \ and \ \frac{1}{9}[/tex]"
Step-by-step explanation:
In point a:
The requires 1 genin, 1 chunin , and 1 jonin to shape a complete team but we all recognize that each nation's team is comprised of 1 genin, 1 chunin, and 1 jonin.
They can now pick 1 genin from a certain matter of national with the value:
[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]
They can pick 1 Chunin form of the matter of national with the value:
[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]
They have the option to pick 1 join from of the country team with such a probability: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
And we can make the country teams: [tex]3! = 6[/tex] different forms. Its chances of choosing a team full in the process described also are:
[tex]6 \times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{2}{9}.[/tex]
In point b:
In this scenario, one of the 3 professional sides can either choose 3 genins or 3 chunines or 3 joniners. So, that we can form three groups that contain the same ninjas (either 3 genin or 3 chunin or 3 jonin).
Its likelihood that even a specific nation team ninja would be chosen is now: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
Its odds of choosing the same rank ninja in such a different country team are: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]
The likelihood of choosing the same level Ninja from the residual matter of national is: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex] Therefore, all 3 selected ninjas are likely the same grade: [tex]3\times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{1}{9}[/tex]

Find angle3 which is 80º
All lines are 180º
which means angle3+ angle4 is 180º
180º - 80º
= 100º
Answer: B. 100°
Step-by-step explanation:
Since triangles contain angles that add up to 180°, angles 3 is 80°. Since Straight Angles are 180°, it means that angle 4 is 180-80, which equals 100°.
A trough is 10 feet long and the ends have the shape of isosceles triangles that measure 3 feet across at the top and have a height of 1 foot. If the trough is being filled with water at a rate of 12 ft3 per minute, how fast is the water level rising when the water is 6-inches deep
Answer:
0.8 ft³/min
Step-by-step explanation:
Assuming that the cross section formed by the water at a depth of x is b. Then, if we use the property of similar triangles we have...

Continuation of the workings
From the question, we're told that the water is 6 inches deep. Converting this inch to ft, we have
6 ft = 0.5 ft.
So we use 0.5 as our x, and then use 12 ft³/min as our dV/dt. Doing this, we have
.
12 = 30 * 0.5 dx/dt
12 = 15 dx/dt
dx/dt = 12/15
dx/dt= 0.8 ft³/min
A farmer owns a field with an area of 0.037 km2. The farmer buys another field with an area of 9600 m2. What is the total area of the fields he now owns in km2?
Answer:
0.0946km²
Step-by-step explanation
Area of the farmland owned = 0.037km²
Area of farm land bought = 9600m²
Convert m² to km²
1m² = 1e-6 km²
9600m² = 0.000001 * 9600
9600m² = 0.0576km²
Total area on km² = 0.037km²+0.0576km²
Total area on km² = 0.0946km²

A model of Steven’s house is shown in the diagram. He is replacing the roof, which consists of two rectangular surfaces. The diagram shows one side of the roof, with the other side hidden from view. What is the total area of the roof to the nearest square foot?
Answer:
Option B
Step-by-step explanation:
From the picture attached,
Area of the one side of the roof = Area of the rectangle
= Length × Width
= AE × AC
To get the length of side AC, construct a perpendicular AD on side BC which divides BC in two equal parts.
BD = DC = 13 ft
By applying cosine rule in ΔADC,
cos(45)° = [tex]\frac{\text{DC}}{\text{AC}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{13}{\text{AC}}[/tex]
AC = 13√2
AC = 18.38 ft
Therefore, area of one side of the roof = 38 × 18.38
= 698.62 square feet
Area of both the sides of the roof = 698.62 × 2
= 1397.24 feet²
≈ 1397 feet²
Option B will be the answer.
The total area of the roof to the nearest square foot is 1,397 square feet
Area of composite shapes.In order to get the area of the roof, we will need the slant height of the triangle.
Using the pythagoras theorem;
[tex]cos45 = \frac{26/2}{l} \\cos 45 = \frac{13}{l} \\0.7071 = \frac{13}{l} \\l = \frac{13}{0.7071} \\l=18.39 feet[/tex]
Get the area of the roofArea of the roof = 2(lw)
l is the length of the rectangle = 38ftw is the width = 18.39 feetArea of the roof = 2(38 * 18.39)
Area of the roof = 1,397.64
Area of the roof ≈ 1,397 square feet
Hence the total area of the roof to the nearest square foot is 1,397 square feet

= 64/350 * 100
= 18.29%
Carl sees 25 melons at the store. 15 are small and the rest are large. How many melons are large?
Answer: 10 large melons
Step-by-step explanation:
Carl saw 25 melons at a store.
Of these 25, 15 were small and the rest were large.
The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:
= 25 total melons - 15 small melons
= 10 large melons
What is the final elevation if a butterfly starts at 20 m and changes negative 16 m
Answer:
4 meters
Step-by-step explanation:
Given that :
Initial elevation of butterfly = 20 meter
Change in elevation from initial height = negative 16 m = - 16 meter
Final elevation can be obtained by taking the sum of initial elevation and the change in elevation
(20 m + (- 16 m))
(20 m - 16 m)
= 4 meters

A container holds 600 kg of rice . 33 1/3% of rice was distributed to groceries . How many kilograms of rice remained in the container
Answer:
Amount left in the container is [tex]400\:\text{kg}[/tex].
Step-by-step explanation:
Given: A container holds [tex]600[/tex] kg of rice. [tex]33 \frac{1}{3} \%[/tex] of rice was distributed to groceries.
To find: How many kilograms of rice remained in the container?
Solution:
We have,
Amount of rice in the container [tex]=600[/tex] kg
Amount distributed to the groceries [tex]=33 \frac{1}{3} \%= \frac{100}{3}\%[/tex]
Therefore, amount distributed to groceries[tex]=\frac{100}{3}\times\frac{1}{100}\times600=200 \:\text{kg}[/tex]
Now, amount of rice left in the container[tex]=600\:\text{kg}-200\:\text{kg}=400\:\text{kg}[/tex]
Hence, amount of rice left in the container is [tex]400 \:\text{kg}[/tex].
[tex]\bold{\underline{Answer : -}}[/tex]
Amount of the rice left in container = 400kg[tex] \: [/tex]
[tex]\bold{\underline{Explanation : -}}[/tex]
(33⅓)% = (100/3)%[tex] \longmapsto \sf( \frac{100}{3} )\% \times 600 [/tex]
[tex] \longmapsto \sf( \frac{ \frac{100}{3} }{100} ) \times 600 \\ \longmapsto \sf\frac{ \cancel{100}}{3} \times \frac{1}{ \cancel{100}} \times 600 \\ \longmapsto \sf \frac{1}{3} \times 600 = \frac{600}{3} = 600 \div3 \\ \longmapsto \bold \red{200kg}[/tex]

The lakeside marina charges a $35 rental fee for a boat in addition to charging $15 per hour. Part D:what information does the initial value represent? A.The cost of renting a boat for one hour B.The cost of rental fee only C.The cost of rental fee plus the boat for one hour D.The cost of renting the boat more than one hour
Answer: B.The cost of rental fee only
Step-by-step explanation:
The $35 is the cost of the rental fee only. The person would then have to pay a further $15 for every hour they use the boat.
Essentially, the $35 is the fixed cost associated with the rental and the $15 is the variable cost to do so. If this were in a linear equation format it would take the form: y = 15x + 35.
Find the solution of the system of equations 3x+3y=6
9x-5y=-24
Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3
What is the slope of a line parallel to the line whose equation is x-3y=-27 Fully reduce your answer
Answer:
1/3Step-by-step explanation:
Note that any line parallel to the given line will have the same slope as the line given.
Given the equation of the line expressed as x - 3y =-27
Rewrite in standard form y = mx+c where m is the slope
x - 3y =-27
-3y = -x -27
Multiply through by -11
3y = x+27
Divide through by 3
y = 1/3 x + 9
Since the slope of the line is 1/3, hence the slope of a line parallel to the line is also 1/3
