See explanation below.
The selection of drop down arrows from top to bottom should be:
5; 4; 1; 2; 3
Step-by-step explanation:
Quadrilateral with exactly ONE set of parallel sides: Trapezoid (option 5)
Parallelogram with 4 congruent (equal) sides and 4 right angles: square (option 4)
Quadrilateral with 2 pairs of parallel sides (notice no reference to angles between sides and constrain about similarity in side length - so this os the most general description): parallelogram (option 1)
Parallelogram with 4 right angles (notice no constrain about the length of the sides): rectangle (option 2)
Parallelogram with 4 congruent sides (notice there is no constrain about the angles between the sides): rhombus (option 3)
Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
Answer:
Step-by-step explanation:
The given data is
42 40 39 31 22 18 15 12 11.7 10.5
Range = 42 - 10.5 = 31.5
Mean = (42 + 40 + 39 + 31 + 22 + 18 + 15 + 12 + 11.7 + 10.5)/10 = 24.12
n = 10
Variance = Summation(x - mean)²/n
Summation(x - mean)² = (42 - 24.12)^2 + (40 - 24.12)^2 + (39 - 24.12)^2 + (31 - 24.12)^2 + (22 - 24.12)^2 + (18 - 24.12)^2 + (15 - 24.12)^2 + (12 - 24.12)^2 + (11.7 - 24.12)^2 + (10.5 - 24.12)^2 = 1452.396
Variance = 1452.396/10 = 145.2396
Standard deviation = √(summation(x - mean)²/n
Standard deviation = √(145.2396
Standard deviation = 12.1
The standard deviation of the sample is not a good estimate of the variation of the salaries of the TV personalities in general because
B. No, because the sample is not representative of the whole population.
