Mean: xbar = (∑i=1...10 xi)/10 = (61 + ... + 100)/10 = 84.4 Sum Of Squares in X SSX = ∑i (x - xbar)2 = (61 - 84.4)2 + ... + (100 - 84.4)2 = 1364.4 Standard deviation Sample: s = √[SSX / (10 - 1)] ≈ 12.3 Population: σ = √(SSX / 10) ≈ 11.7
Answer:
the answer is 28
Step-by-step explanation:
the mode is what comes up the most and 28 is the only one with 2
Answer:
Step-by-step explanation:
If this is in relation to the number 100, .57% is less than(<) 11
Triangle:
A = 3 x 9 x 1/2 = 13.5
Large rectangle (center):
A = 9 x 12 = 108
Medium rectangle:
A = 4 x 6 = 24
Small rectangle (bottom):
A = 4 x 2 = 8
Figure:
A = 13.5 + 108 + 24 + 8 = 153.5 square feet
Hope this helps! :)
