÷Answer:
Standard Deviation = 176.5
Step-by-step explanation:
To calculate the standard deviation, calculate the mean score for the 4 standard deviation scores:
mean, m = Σx ÷ n
where Σx represents summation of each value = 162 + 153 + 317 + 413
= 1045
n = number of samples to be considered = 4
mean, m = 1045 ÷4
= 261.25
To calculate the standard deviation, use the formula below
SD =
where x = each value from the week lead time
m = mean = 261.25
n = the size = 4
The Standard deviation formula can be simplified further
when x = 162
= 49.625
when x = 153
= 23.125
when x = 317
= 27.875
when x = 413
= 75.875
Note that the above 4 equations can be lumped up into one giant equation by applying a big square root function instead of breaking it down
SD = 49.625 + 23.125 + 27.875 + 75.875
SD = 176.5
Answer:
8
Step-by-step explanation:
∠1 = (6x + 2)° (vertically opposite angles are equal)
15x + 10° +∠1 = 180° (co-interior angles are equal)
15x + 10° + 6x + 2° = 180°
15x + 6x + 10° + 2° = 180°
21x + 12° = 180°
21x = 180° - 12°
21x = 168°
x = 168/21
x = 8

Hi there!
The answer is $140.
Could you please Brainliest me?
Answer:
1936 m2
Lot = 60 x 36 = 2160m^2
House = 28 x 8 = 224m^2
Area not covered by the house = 2160^2 - 224^2
= 1936m^2
Hope this helps !!
