The weight of tigers follow a normal distribution with a mean of 220 kg and a SD of 30 kg. 1) If we randomly select a tiger, wha
t is the probability that his weights is less than 258 kg
1 answer:
Answer:
0.89736
Step-by-step explanation:
We solve this question using z score formula
Z score = x - μ/σ
x = raw score
μ = population mean
σ = population standard deviation
Hence,
x = 258, μ = 220, σ = 30
Z = 258 - 220/30
=1.26667
Probability value from Z-Table:
P(x<258) = 0.89736
Therefore, the probability that his weights is less than 258 kg is 0.89736

D. 50. Since WZ is perpendicular, it has a right angle plus the 40 degrees given at V equals 130. Add 50 to get 180.
3 because 3•3 is 9 and 9•3 is 27
Well metric unit is for measurement and place value units is for numbers
The empirical rule states that approximately 68/95/99.7% of a normal distribution lies within 1/2/3 standard deviations. So the answer is 68%.
