Answer:
294.1 pounds
Step-by-step explanation:
Step 1
We find the z score for 90th percentile
= 1.282
Step 2
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score ??
μ is the population mean = 230 pounds
σ is the population standard deviation= 50 pounds
1.282 = x - 230/50
Cross Multiply
1.282 × 50 = x - 230
64.1 = x - 230
x = 230 + 64.1
x = 294.1 pounds
The birth weight of elephants at the 90th percentile is 294.1 pounds.

So 10 rotation would be 10 times the circumferece
28pi*10=280pi or 879.65ft
Answer:

Step-by-step explanation:
Lets get a common denominator
2/3 *2/2 = 4/6
1/2 * 3/3 = 3/6
