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: 7.3 km
Step-by-step explanation:
the equation for circumference is C=лd
so it will be
C=Л x 2 1/3 = 7.3330 kilometer
and if u want it in meter it will be C=л x 2 333.33333 = 7330.38 meter
Answer:a.100+(hx25)
b.120+(hx20)
c.4 hours
h=hours
Step-by-step explanation:
Answer:
y = x + 8
Step-by-step explanation:
(x² + 6x - 9)/(x - 2)
[x² - 2x + 8x - 16 + 7]/(x - 2)
[x(x - 2) + 8(x - 2) + 7]/(x - 2)
x + 8 + 7/(x - 2)
Oblique asymptote: y = x + 8
