The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally
creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. \mu= 1470 ,  \sigma = 230, x=1750

The relationship between z score, mean and standard deviation is given by

x = \mu+z\sigma

So the z value according to this is given by the formula

1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile

33762 to the nearest thousand?
Reil [10]

Answer:

34,000

179,400

39,900

Step-by-step explanation:

In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.

Since 7 is more than 5, we round up, so our rounded number would be

34,000

Let’s use this logic for the rest of these numbers

179,406

4 is in the hundreds

Previous number in 0 which is less than 5, so it rounds down

179,400

39,994

9 is in the tens place

Previous number is 4 which is less than 5, so it rounds down

39,990
