Find two sets of three positive single digit integers with mmr equal to 4/5'
Answers
We find sets of three positive single digit integers with a mean of 4 and a range of 5 is {1, 5, 6} and another possible set is {2, 4, 6}.
Here mmr is mean, median, and range of a set of numbers. The mean of a set of numbers is the sum of all the numbers divided by the total number of numbers in the set. The median of a set of numbers is the middle number when the numbers are arranged in order.
The range of a set of numbers is the difference between the largest and smallest numbers in the set.
To find two sets of three positive single digit integers with a mean of 4 and a range of 5, we can use the formula:
Mean = (sum of numbers) / (number of numbers)
Since we want the mean to be 4, the sum of the three numbers in each set must be 12. Since we want the range to be 5, the largest number in each set must be 5 more than the smallest number.
One possible set of three numbers that satisfies these conditions is {1, 5, 6}. The mean of this set is (1+5+6)/3 = 4, and the range is 6-1 = 5.
Another possible set of three numbers that satisfies these conditions is {2, 4, 6}. The mean of this set is (2+4+6)/3 = 4, and the range is 6-2 = 4.
Therefore, two sets of three positive single digit integers with a mean of 4 and a range of 5 are {1, 5, 6} and {2, 4, 6}.

Step-By-Step:
The height triangle has a height of 17.3 yards and a width of 12 yards. 3. Finally, connect the two triangles to create the pyramid's surface area. The surface area of the pyramid is 116.7 yards².
Answer:
116.7 yards².
Answer:
The first step is to find the area of the base triangle:
Area = (1/2) x base x height
Area = (1/2) x 20 yards x 17.3 yards
Area = 173 square yards
To find the surface area of the pyramid, we need to find the areas of the four triangular faces and add them to the base area.
Area of a triangular face = (1/2) x base x height
Area of each face = (1/2) x 20 yards x 12 yards
Area of each face = 120 square yards
Now we can add up all the areas:
Surface area = base area + area of four faces
Surface area = 173 square yards + 4 x 120 square yards
Surface area = 653 square yards
Therefore, the surface area of the pyramid is 653 square yards.
In a class of 40 students each student take at least One of Physics and Chemistry. If the number of student that take Physics is three times the number that take both Subsect and the number that take chemistry is twice the number that take Physic, find the number of Student that take Physics only
Answers
the number of students who take only Physics is 15.
Define equationAn equation is a mathematical statement that shows that two expressions are equal. It is typically written using an equal sign (=) between the two expressions. The expressions on either side of the equal sign are called the left-hand side (LHS) and the right-hand side (RHS) of the equation.
Let's denote the number of students who take only Physics by x.
The total number of students who take Physics or Chemistry=40The number of Physics students is three times the number who take both: number of Physics students = 3The number of Chemistry students is twice the number who take Physics: number of Chemistry students = 2We can use these equations to solve for x, the number of students who take only Physics:
40 = 3(number who take both) + 2(number of Physics students) - number who take both40 = 2(number who take both) + 2(number of Physics students)20 = number who take both + number of Physics studentsSubstituting the expression for the number of Physics students in terms of the number who take both, we get:
20 = number who take both + 3(number who take both)
20 = 4(number who take both)
number who take both = 5
this value in the expression for the number of Physics students, we get:
number of Physics students = 3(number who take both) = 15
Finally, we can use the first equation to solve for the number of students who take only Physics:
40 = 15 + 2(number of students who take only Physics) - 5
40 = 10 + 2(number of students who take only Physics)
number of students who take only Physics = 15
Therefore, the number of students who take only Physics is 15.

Find the general term of 6,12,24,48,...
Answers
Answer:
an = 6 * 2^(n-1)
Step-by-step explanation:
To find the general term of the sequence 6, 12, 24, 48, ... , we need to observe that each term is obtained by multiplying the previous term by 2. Therefore, the sequence is a geometric sequence with first term a = 6 and common ratio r = 2.
The formula for the nth term of a geometric sequence is:
an = a * r^(n-1)
Substituting a = 6 and r = 2, we get:
an = 6 * 2^(n-1)
Therefore, the general term of the sequence 6, 12, 24, 48, ... is given by the formula an = 6 * 2^(n-1).

In a marathon race of 21 km a runner has been running at a constant speed of 5 by 3 m per second for the last 3 hour. How much distance remain to be run to finish the marathon
Answers
the runner still needs to run a distance of 15 km to finish the marathon.
To find out how much distance remains to be run in the marathon, we can first calculate how far the runner has already run in the last 3 hours. We can use the formula:
distance = speed x time
where speed is in meters per second and time is in hours.
The runner has been running at a constant speed of 5/3 m/s for 3 hours, so the distance covered so far is:
distance = (5/3) m/s x 3 hours x 3600 seconds/hour
distance = 6000 meters or 6 km
Therefore, the runner has already completed 6 km of the marathon, which means that the remaining distance to be run is:
remaining distance = total distance - distance already covered
The total distance of the marathon is 21 km, so the remaining distance is:
remaining distance = 21 km - 6 km
remaining distance = 15 km
Therefore, the runner still needs to run 15 km to finish the marathon.

what is the equation for a cosecant function with vertical asymptotes found at such that n is an integer?
Answers
The equation for a cosecant function with vertical asymptotes found at x = nπ such that n is an integer is `y = csc(x - nπ)`.
The cosecant function is the reciprocal of the sine function. The cosecant of a particular angle in a right triangle is the ratio of the hypotenuse to the side opposite the angle.
The cosecant function is written as follows: `csc(x) = 1/sin(x)`
Asymptotes are straight lines or curves that a graph approaches but never touches.
As a result, the graph of a curve gets closer and closer to the asymptote as it moves further away from the origin, but it never touches it.
For a function to have vertical asymptotes at `x = nπ`, the denominator of the function should equal zero. In the cosecant function, the denominator is equal to `sin(x - nπ)`.
Therefore, the vertical asymptotes are where `sin(x - nπ) = 0`.
The general form of the cosecant function is `y = A csc(B(x - C)) + D`.
The constants A, B, C, and D are used to alter the form of the graph of the cosecant function.
They can be used to alter the amplitude, period, phase shift, and vertical displacement of the graph, respectively.

Find the area of a segment of a circle if the central angle of the segment is 50° and the radius is 15
Answers
In conclusion the area of the segment is approximately 32.76 square units.
How to find?
To find the area of a segment of a circle, we can use the formula:
Area of segment = (θ/360)πr²2 - (1/2)rsin(θ)
where:
θ is the central angle of the segment in degrees
r is the radius of the circle
π is a constant approximately equal to 3.14
sin is the sine function
In this case, the central angle is 50° and the radius is 15. Substituting these values into the formula, we get:
Area of segment = (50/360)π(15)²2 - (1/2)(15)sin(50)
= (5/36)π(225) - (1/2)(15)(0.766)

(1) The scale factor for this dilation is 1/6.
(2) The scale factor for this dilation is 6.
(3) False. A dilation with a scale factor less than 1 is a reduction, not an enlargement.
What is the scale factor?1. To find the scale factor for the dilation with center at the origin that maps point M(-12,18) to M(-2,3) we can use the formula:
new coordinate / old coordinate = scale factor
For the x-coordinate:
-2 / -12 = 1/6
For the y-coordinate:
3 / 18 = 1/6
Since both coordinates have the same scale factor, we can conclude that the scale factor for this dilation is 1/6.
2. To find the scale factor for the dilation with center at the origin that maps point M(-2,3) to M'(-12,18) we can again use the formula:
new coordinate / old coordinate = scale factor
For the x-coordinate:
-12 / -2 = 6
For the y-coordinate:
18 / 3 = 6
Since both coordinates have the same scale factor, we can conclude that the scale factor for this dilation is 6.

a man sets out to travel from A to C via B. from A he travel a distance of 8km on a bearing of north 30°east to B. from B he travel a further 6km due east. calculate how far c is from north of A, east of A.
Answers
DC is how Far East C is from A
To find AD:
Using Pythagorean’ theorem
AD= 3Cos30
= 3*0.866
=6.9km
… C is 6.9km north of A
11) DC = DB+BC
BC=6km
DB=?
DB= 8sin30
=8*0.5
=4km
DC=8+4=10km
… C is 10km east of A

The area of the circle is 200.96 square kilometers, the area of the polygon is 181.02 square kilometers and the shaded region is 19.94 square kilometers.
Calculating the area of the shaded region
The area A of a circle with radius r can be found using the formula:
A = πr^2
Plugging in the given value of radius, we get:
A = π(8 km)^2
Simplifying the expression, we get:
A = 64π km^2
So, we have
A ≈ 64 x 3.14 km^2
A ≈ 200.96 km^2
To find the area of an octagon with a radius of 8 km, we can break it up into eight congruent isosceles triangles.
So, we have
Area = 8 * Area of triangle
This gives
Area = 8 * 1/2 * r² sin(central angle)
So, we have
Area = 8 * 1/2 * 8² sin(45)
Evaluate
Area = 181.02
The shaded area is
Shaded = 200.96 - 181.02
Shaded = 19.94
Hence, the shaded area is 19.94 square kilometers.

a reporter for an international newspaper is given an assignment that is randomly chosen from the following destinations worldwide: 8 continental united states assignments, 29 south american assignments, 15 european union assignments, and 22 asian assignments. find the probability that he gets an assignment in the united states or asia . express your answer as a fraction
Answers
The probability that the reporter gets an assignment in the United States or Asia is 15/37.
To find the probability that the reporter gets an assignment in the United States or Asia, we first need to determine the total number of assignments in the pool.
Total number of assignments = 8 + 29 + 15 + 22 = 74
Next, we need to determine the number of assignments that are in the United States or Asia.
Number of assignments in the United States or Asia = 8 + 22 = 30
Finally, we can calculate the probability of the reporter getting an assignment in the United States or Asia by dividing the number of assignments in the United States or Asia by the total number of assignments:
Probability of getting an assignment in the United States or Asia = (Number of assignments in the United States or Asia) / (Total number of assignments)
Probability of getting an assignment in the United States or Asia = 30/74
Therefore, the probability of the reporter getting an assignment in the United States or Asia is 30/74, which can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF), which in this case is 2:
Probability of getting an assignment in the United States or Asia = 15/37

Emergency help needed will mark brainliest
Answers
Answer: The first graph
Step-by-step explanation: because the vertex is (3,-1)
Then plug in number like is 1 is x solve for y which will be -3
if x is 2, y is -3/2
x is 3, y is -1
x is 4, y is -3/2
x is 5, y is -3
Answer:
Vertex at (3,-1) and flipped upside down (opening downward)
*looks like the first one of the first attachment*
Step-by-step explanation:
The normal untransformed parabola is a U-ish, V-ish curve that has its vertex at (0,0) and it opens upward. There are "nice" points at (1,1) and (2,4) also at (-1,1) and (-2,4) Your parabola has had four changes made to it:
□The negative sign in front on your equation will FLIP the whole thing upside down so it opens downward.
□The 1/2 in front will "smash" the parabola so it is flatter and wider.
□The - 3 that's in close next to the x will shift (slide, translate) the whole thing to the right 3 units **left and right shifts are kind of the opposite of what you might think: - shifts right and + shifts left**
□The -1 tacked on to the end will shift (slide, translate) the whole thing down one unit. **more intuitive, - shifts down and + shifts up**
