The weight of 824 pounds of a polar bear has a z-score of -1.50.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation

Given that μ = 950, σ = 84

For z = -1.50:

-1.50=\frac{x-950}{84}\\\\x-950=-126\\\\x=824

The weight of 824 pounds of a polar bear has a z-score of -1.50.

Which is the better buy a 3 pound ham for $5.70 or 5 pounds for $8.75
tekilochka [14]

Answer:

The larger ham is the better buy.

Step-by-step explanation:

In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.

5.70/3 = 1.90 per lb

8.75/5 = 1.75 per lb

Therefore the 5 pound of ham is a better buy.

Novay_Z [31]

Answer:

There will be 2 numbers of individual bags of chocolates left with Missy.

Step-by-step explanation:

Missy bought 4 bags of chocolates and there are 8 pieces of chocolates in each bag.

Therefore, there was a total (4× 8) = 32 chocolates.

Now, her kids ate 6 of the chocolates.

So, there remains (32 - 6) = 26 chocolates left.

If Missy packed the remaining chocolates into individual bags with 13 chocolates in each bag, then there will be \frac{26}{13} =2 numbers of individual bags of chocolates left with Missy. (Answer)
