Answers
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

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.

At a NASCAR racetrack, the distance per lap is 2 miles. Lou Lambert drives his car at a constant rate of 160 miles per hour. Ralph Redding drives his car at a constant rate of 170 miles per hour. How long will it take before Ralph gains 2 laps in relation to Lou?
Answers
Answer:
24 minutes
Step-by-step explanation:
Given:
Distance per lap = 2 miles
Speed of Lou Lambert = 160 miles/hr
Speed of Ralph Redding = 170 miles/hr
Speed difference between the two = 170 - 160 = 10 miles/hr
Therefore, we can say that Ralph gains 10 miles in 60 minutes over Lou.
We have to find the time in which Ralph will gain 2 laps i.e. 2 [tex]\times[/tex] 2 = 4 miles.
Let us use unitary method to find the required time.
10 miles are gained by Ralph in 60 minutes
1 mile will be gained in [tex]\frac{60}{10} = 6\ minutes[/tex]
4 miles will be gained in 6 [tex]\times[/tex] 4 = 24 minutes

Which option above can be written as a geometric sequence?
A. Option 1
B. Option 2
C. Both Option 1 and 2
D. Neither Option 1 or 2
Answers
Answer:
B. Option 2 (only)
Step-by-step explanation:
A geometric sequence is a sequence of terms that have a common ratio.
Option 1The deposits are ...
100, 50, 50, 50, ...
The ratios of terms of this sequence are ...
1/2, 1, 1, 1
So, the ratio is not constant, and the sequence is not geometric.
__
Option 2The deposits are ...
5, 10, 20, 40, ...
The ratios of terms of this sequence are ...
10/5 = 2, 20/10 = 2, 40/20 = 2, ...
The ratio is constant, so the sequence of deposits for Option 2 is geometric.

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
