Biased or Unbiased: Take 20 packages off the top of the load of packages being shipped by a truck and measure the amount of damage expected to the whole truckload.

Answer: It is a biased way of taking sample. Because the top layer of packages has less weight resting on it and may have less damage. Therefore, the given statement is biased and based on these 20 packages of the top of the load, we can not make a decision about how much damage a truckload contains.

Natalie and John are both saving coins in jars for a rainy day. Natalie currently has 1 1/8 jars of coins, and John has 9/14 of
aivan3 [116]

Answer:

Natalie will have 1\frac{43}{56} jars of coins all together after receiving John's coins.

Step-by-step explanation:

Given that:

Coins Natalie have = 1\frac{1}{8} jars of coins

Coins John have = \frac{9}{14} jars of coins

When John will give all his coins to Natalie.

Total coins Natalie have = Her coins + John's coins

Total coins Natalie have = 1\frac{1}{8}+\frac{9}{14}

Total coins = \frac{9}{8}+\frac{9}{14}

Total coins =\frac{63+36}{56}=\frac{99}{56}

Total coins = 1\frac{43}{56}

Hence,

Natalie will have 1\frac{43}{56} jars of coins all together after receiving John's coins.
