A number less than 0 is called _____

Albert loves to cook with fresh herbs. So, he decides to plant 8 different herbs and keep the small pots on his kitchen windowsi

Answer:

8 oz

Step-by-step explanation:

Albert is planting 8 different herbs, so we can assume he is using 8 pots. Start by converting pounds to ounces:

1 lb = 16 oz

4 lbs = 64 oz

Now we divide 64 oz into 8 pots:

64/8 = 8 (because 8^2 = 64)

Albert puts 8 oz of soil in each pot.

Hope this helps!

The operation manager at a tire manufacturing company believes that the mean mileage of a tire is 48,564 miles, with a standard

DerKrebs [107]

Answer:

0.0091 = 0.91% probability that the sample mean would be less than 48,101 miles in a sample of 281 tires if the manager is correct

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central limit theorem:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$
