The range is: 13. The population mean is: 8.5. The population variance is: 15.85. The population standard deviation is: 3.9812.
Step-by-step explanation:
The range: 15 - 2 = 13
The population mean is:
Mean = ( 2 + 9 + 15 + 5 + 14 + 8 + 11 + 7 + 4 + 10 ) / 10 = 8.5
The population variance ( S² or Sigma² ):
S ² = 1/10 · ( ( 2 - 8.5 )² + ( 9 - 8.5 )² + ( 15 - 8.5 )² + ( 5 - 8.5 )² + ( 14 - 8.5 )² + ( 8 - 8.5 )² + ( 11 - 8.5 )² + ( 7 - 8.5 )² + ( 4 - 8.5 )² + ( 10 - 8.5 )² )
S ² = 15.85
The population standard deviation:
S = √(S²) = √15.85 = 3.9812
The value of range = 13
The value of mean = 8.4
The value of variance = 23.6
The value of standard deviation = 4.86
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Population data set:
2, 10, 15, 2, 12, 6, 14, 10, 3, 10.
Range:
= Highest - Lowest
= 15 - 2
= 13
Now,
Mean.
= (2 + 2 + 3 + 6 + 10 + 10 + 10 + 12 + 14 + 15) / 10
= 84/10
= 8.4
Now,
S = Sum of all (x - Mean)²
S = (2 - 8.4)² + (2 - 8.4)² + (3 - 8.4)² + (6 - 8.4)²+ (10 - 8.4)² + (10 - 8.4)² + (10 - 8.4)² + (12 - 8.4)² + (14 - 8.4)² + (15 - 8.4)²
S = 212.4
n = 10
n - 1 = 9
So,
Variance.
S² = S/(n - 1)
= 212.4/9
= 23.6
Now,
Standard deviation = √S²
So,
= √23.6
= 4.86
Thus,
Range = 13
Mean = 8.4
Variance = 23.6
Standard deviation = 4.86

The dimensions of this figure are changed so that the new surface area is exactly 1/3 what it was originally. What is the new surface area? Enter your answer as a decimal in the box. ft² Please help! tysm ♥
Answers
Surface Area of original figure= 577.49 ft2
Surface Area of new figure
= 1/3 x 577.49 = 192.497
= 192.5 ft2
Detailed Solution is in the picture below
The new surface area is 198.79 ft².
What is Surface Area?An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.
As per the given diagram:
All the dimensions are mentioned
new surface area is exactly (1/3) of original surface area.
Original surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) + (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)
Original surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89
original surface area = 596.38 ft²
Therefore,
New surface area = (1/3) of original surface area
= (1/3) × 596.38
= 198.79 ft²
Hence, the new surface area is 198.79 ft².

Alexandra has a stand in the marketplace where she sells ground cumin. She has a fixed amount of weekly expenses, and she sells her cumin for \$7.20$7.20dollar sign, 7, point, 20 per kilogram. If she sells 909090 kilograms of cumin, her weekly net profit is \$414$414dollar sign, 414.
Answers
Answer:
Alexandra's weekly expenses is $234
Step-by-step explanation:
Selling price of 1 kg cumin = $7.20
She sells amount of cumin = 20 kg
Selling price of 90 kg cumin = 90 \times 7.20
Selling price of 90 kg cumin =648
We are given that his weekly profit is $414
We are supposed to find his weekly expense
So, Expense = SP - Profit
Expense = 648-414
Expense=$234
Hence Alexandra's weekly expenses is $234

A person can pay $7 for a membership to the science museum and then go to the museum for
just $1 per visit. What is the maximum number of visits a member of the science museum can
make for a total cost of $46? Write an equation and solve. Show all work!
Answers
Answer:
39 visits.
Step-by-step explanation:
In order to solve, we must add the cost of the membership and the cost of the visits to get the sum of 46.
$7 is the cost of the membership, so thats going to be the first number we add. If you revist the museum, you will need to pay $1. Now to save time and space, I will not continusely write $1 until we get to 46, but instead, subtract 46 from 7. The difference we get will be the number of visits. I will be using the variable v to represent the difference/maximim number of visits a member of the science museum can make for a total cost of $46.
Current Equation: 7+1v = $46.
46 - 7 = 39.
7+1(39) = 46
I agree with the previous answer. It indeed is 39.
46-7=39 (7 - price of the membership)
39/1=39 (1 - price of the tickets)
What is the measure of angle x?
Answers
Explanation: the triangle is equal to 180, 35 plus 90 is 125 and 180-125= 55.
Answer:
B) 55°
Step-by-step explanation:
The ∑ of all interior angles of a triangle is 180°.
When you see a square in a angle (as seen in the bottom left of the triangle), it means that it is a right angle, or 90° in measurement.
Set the equation:
180 = x + 90 + 35
First, combine like terms:
180 = x + (90 + 35)
180 = x + 125
Next, subtract 125 from both sides of the equation to isolate the x:
180 (-125) = x + 125 (-125)
x = 180 - 125
x = 55
55°, or B) is your answer.
