The median of the number recorded in the question is 51.5 feet. This is obtained by dividing the sum of two numbers that occur centrally in half.
What is median?The central value in a list ordered from smallest to largest is the median of a set of values.
What is the Inter-quartile Range (IQR) of an observation?The formula for the Inter-quartile range is given as:
IQR = Q₃- Q₁ (that is Median of the Upper Half Less the Median of the lower half)
Step 1 - First, let's arrange the numbers sequentially
→ 40, 40, 47, 49, 50, 53, 55, 57, 63, 76
Step 2 - Determine the upper and lower halves and their median
If the Lower half is 40, 40, 47, 49, 50, then it's median is 47
If the Upper half is 53, 55, 57, 63, 76, then its median is 57.
Hence:
IQR = 57 - 47
= 10 feet.
Given that the median of the second data set is 49 feet, and the IQR is 6 feet. Did the 10 friends, as a group, perform better (or throw farther) in the second?No, the friends didn't perform better in the second round because the was a significant drop in the median and the IQR. The median dropped from 51.5 to 47 and the IQR from 10 to 6.
It can be concluded that the distance in the second set of data is less variable when juxtaposed with those form the first set.

The value of the trigonometry equation (sin 60)(cos 30)+(cos 60)(sin 30) is sin (60+30). Option J is correct.
What is the formula of sum of sin (a+b)?The formula of sum of sin (a+b) is the trigonometry identity which is used to solve and simplify the problem based on trigonometry equation.
The formula of sum of sin (a+b),
Sin(A+B)=(sin A)(cos B)+(cos A)(sin B)
Here, (A and B) are the measure of angles.
The trigonometry equation given in the problem is,
(sin 60)(cos 30)+(cos 60)(sin 30)
Compare this expression with the above formula we get,
A=60
B=30
Thus, the value of the given expression is,
(sin 60)(cos 30)+(cos 60)(sin 30)=sin (60+30)
Thus, the value of the trigonometry equation (sin 60)(cos 30)+(cos 60)(sin 30) is sin (60+30). Option J is correct.

A cube is a three-dimensional solid object having six square faces. The measure of the length of the diagonal of the face of the cube is 12.2 cm.
What is a cube?A cube is a three-dimensional solid object having six square faces, facets, or sides, three of which meet at each vertex. The cube is one of the five Platonic solids and the only regular hexahedron.
Given the length of an edge of the cube is √75 cm, therefore, the length of the diagonal of the face of the cube will be √2 times the length of an edge of the cube. Thus, the measure of the length of the diagonal of the face of the cube is,
Length of the diagonal of the face = √2 × √75 = 12.2 cm
Hence, the measure of the length of the diagonal of the face of the cube is 12.2 cm.

If an event is very likely to occur, the probability is between ____ and ____ on the probability spectrum
If an event is likely to occur, the probability that the event will occur is between 3/4 and 1.
What is the probability?Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
If the probability lies between 0 and 1/5, it is likely that the event would not occur. If the probability lies between 1/5 and 1, it is likely that the event would occur.

Ram has two plots in two different places. Both are square in shapes. The side of the first field is 350m and the side of the other field is 220m. Find the total area of the fields that Ram has?
The total area of the fields that Ram has is 170,900 square meters ( 170900 m²)
Calculating the areas of squaresFrom the question, we are to determine the total area of the fields that Ram has
Since the fields are square in shapes, we will use the formula for calculating the area of a square
The area of a square can be calculated by using the formula,
A = s²
Where A is the area
and s is the side
For the first field
s = 350 m
∴ A = 350²
A = 122500 m²
For the second field
s = 220 m
∴ A = 220²
A = 48400 m²
Then,
The total area of the fields = 122500 m² + 48400 m²
The total area of the fields = 170900 m²
Hence, the total area of the fields that Ram has is 170,900 square meters ( 170900 m²)

You know that 3 pencils and 7 pens cost $24, while 3 pencils and 3 pens cost S12.
How many dollars are 4 pencils and 5 pens worth?
Answer:
5 pens = 15$ and 4 pencils = 4$
Step-by-step explanation:
7-3=4, so 4 pens is 12$
12/4 = 3, so 1 pen = 3$
Remove the pens from the equation
7x3=21
24-21=3
3/3=1, so each pencil costs 1$
4 pencils and 5 pens are worth $23.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let the cost of one pencil be x, and the cost of one pen be y.
Then we can set up the following system of equations based on the given information:
3x + 7y = 24 ...(1)
3x + 3y = 12 ...(2)
Solving these two equations, we can find that x = 2 and y = 3.
Now, we can use these values to find the cost of 4 pencils and 5 pens:
4x + 5y = 4(2) + 5(3) = 8 + 15 = $23
Therefore,
4 pencils and 5 pens are worth $23.

Answer:
x = 8
z = 65
Step-by-step explanation:
Through various rules, we are able to assert: (6x + 67)° = 115°.
Now, we want to solve for x:
6x + 67 = 115
6x = 48
x = 8
We know that z° is equal to the complement of (6x + 67)°, and together these must sum to 180°. Therefore, we can simply take 180° - 115° to find that z° = 65°.
