The following data are the distances between a sample of 20 retail stores and a large distribution center. The distances are in miles.
29; 32; 38; 40; 58; 67; 68; 69; 76; 81; 85; 95; 96; 96; 99; 106; 112; 127; 145; 150
Find the value that is one standard deviation below the mean. (Round your answer to one decimal place.)
Please help!!!!
Answers
Mean = sum of all numbers / 20 = 1669 / 20 = 83.45
Standard deviation = 7.86
Z-score = -1
So...
Z = (x - mean) / standard deviation
x = Z * standard deviation + mean = -1 * 7.86 + 83.45 = 75.59
Rounded: 75.6

Liner or non linear and why
Answers
If a function is non-linear, there must be an exponent in the equation. For example, [tex]x^{2}[/tex] or [tex]x^{3}[/tex].
Since this function has no exponent attached to the x-variable, we can assume this function is linear.
In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss
Answers
Based on the estimate from the Waldfogel study, 10[tex]\%[/tex] of this would be a deadweight loss, i.e., [tex]\[/tex]90.6 would be the deadweight loss.
Deadweight loss means the economic inefficiency that takes place when the allotment of resources in a market isn't at the optimal position.
The study suggested that the average recipient's valuation of the gift received was approximately 90[tex]\%[/tex] of the actual purchase price of the gift.
This means that 10[tex]\%[/tex] of the value of the gift gets lost in between.
This loss of 10[tex]\%[/tex] in value constitutes the deadweight loss.
The average amount spent on gifts = $906
Percentage loss in value = 10[tex]\%[/tex] or 0.10
Calculation of the deadweight loss,
DWL = Average amount spent on gifts × Percentage loss in value
DWL = [tex]\[/tex]906 × 0.10
Thus, the deadweight loss would be [tex]\[/tex]90.6.

what are complex numbers ??? please gyus itz urgent .....!
Answers
Explanation:
Complex numbers are numbers that have both imaginary and real number parts. Imaginary numbers occur when you take the square root of negative numbers. Here are some examples of imaginary numbers:
[tex]\sqrt{-1} = i[/tex] and [tex]\sqrt{-16} = 4i[/tex]
Real numbers are just normal numbers.
Complex numbers can be expressed generally in the form:
[tex]a+bi[/tex]
[tex]\int{[sin(9x)cos(9x)]} \, dx[/tex]
Answers
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
Then we can write
sin(9x) cos(9x) = 1/2 sin(2 • 9x) = 1/2 sin(18x)
Then
∫ sin(9x) cos(9x) dx
= 1/2 ∫ sin(18x) dx
= -1/2 • 1/18 cos(18x) + C
= -1/36 cos(18x) + C
though you could continue with another double angle identity,
cos(2x) = cos²(x) - sin²(x)
to rewrite the antiderivative as
= -1/36 (cos²(9x) - sin²(9x)) + C
= 1/36 (sin²(9x) - cos²(9x)) + C

The total distance an ant crawls varies directly with the time in seconds. The ant crawls a total distance of 160 centimeters in 20 seconds.
What is the time in seconds the ant crawls when the total distance is 216 centimeters?
8 s
11 s
25 s
27 s
Answers
Answer:
27sStep-by-step explanation:
Given data
total distance=160 cm
time taken =20seconds
We know that speed =distance/time
So let us solve for the speed of the ant
speed=160/20
speed= 8cm/s
Also when the distance is 216,and the ant uses the same speed,it will take the ant
time=distance/speed
time=216/8
time= 27seconds

The precise term in "non-negative." Absolute value is a magnitude and is either positive or zero. Zero is neither positive nor negative. But the absolute value of any non-zero number can be thought of as it's distance from zero and it will always be positive. My Answer: -4 because it’s the distance from 4 to 0 and it’s negative so it’s in the left of the number line.
