Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Step-by-step explanation:

-2/15 = -0.133
This gives you (-0.33)(-0.133)
Next, multiply both brackets together.
(-0.33)(-0.133) = appx. 0.044
Now that you have the product of the two brackets, calculate 5/6

Need answer asap, will give brainly if its right
Answers
Answer: 36 inches (in.)
Step-by-step explanation:
The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).
We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.
We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.
Input the given values into the formula and you get the following:
\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)
\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)
\(36 +x =39\)
\(x=3\)
Therefore, the length from the ball to the hole is 3 feet (ft.).
BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.
Therefore, the distance from the ball to the hole is 36 inches (in.).

Mateo’s aunt bought a share of stock many years ago.
The value of the stock increased by 80%.
Its value is now $270.
What was the value of the stock when Mateo’s aunt bought it?
Answers
The stock has increased 80% hence it is now worth 180%.
Find the original 100%.
First find 1% (Divide by 180)
$270/180 = $1.50
Now find 100% (Multiply by 100)
$1.50 X 100 = $150
The answer is $150
The value of the stock when Mateo’s aunt bought it was $150.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need to find the value of the stock when Mateo’s aunt bought it.
Given that the value of the stock increased by 80%. Its value is now $270.
The stock has increased 80% thus it is now worth 180%.
Then Divide by 180;
$270/180 = $1.50
Now find 100% then Multiply by 100;
$1.50 X 100 = $150

Complete the steps below to find the length and width of the football field as it appears in one of Lewis’s scale drawings.
Part A
What is the actual area of the football field? Assume that the field is shaped like a rectangle.
Answers
Answer:
5,333 1/3
Step-by-step explanation:
The length of the football field is 100 yards. The width of the field is 53 1/3 yards.
The area of a rectangle is length × width:
area = length * width
= 100 yd. * 53 1/3 yd.
= 5,333 1/3 sq. yd.
The area of the football field is 5,333 1/3 square yards.
<3
The exact area of the rectangular field would be as follows:
\(5,333 1/3\) sq. yards
Given that,
Length of the field \(= 100 yards\)
Width of the field \(= 53\) \(1/3 yards\)
So,
Area of rectangle \(= length\) × \(Width/Breadth\)
\(= 100 yards\) × \(53\) \(1/3 yards\)
\(= 5, 333\) \(1/3\) \(sq.\)yards
Thus, the exact area of the rectangular field would be \(5,333 1/3\) sq. yards.

whats the surface area?
Answers
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

A rectangular prism is 2 inches by 4 inches by 6 inches.
Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”
Do you agree with Kimaya? Explain or show your reasoning.
Answers
No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.
So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.
Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.
Simple Explanation: 2/5 in. cubes are more than 1/5 in. cubes, so 1/5 in. cubes would take 2x more to fill than 2/5 in.
Complex Explanation: 2 in. x 4 in. x 6 in. is 48 cubic in. and to fill 48 cubic in. using 2/5 in. per cube, it would be 120. as for 1/5 in., to fill 48 cubic in. with that would be 240. Easier way to think of it is that 2/5 in. cubes are already 120 and 1/5 would be doubling that so all you gotta do is multipy 120 x 2 since filling it with 1/5 would be 2x the amount than 2/5.
