<u><em>Answer:</em></u>
Yung bought 46 pieces of bubble gum for $4.6
<u><em>Explanation:</em></u>
We are given that each piece of gum cost $0.1 and that he spent $4.6 on gums
<u>To get the number of gums he bought, we will simply use cross multiplication as follows:</u>
1 piece .........................> 0.1
x pieces ......................> 4.6
<u>Therefore:</u>
pieces of gum
Hope this helps :)
Answer:
B. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases
Step-by-step explanation:
Standard deviation of distribution of sample means = ![\sigma_{m}](https://tex.z-dn.net/?f=%5Csigma_%7Bm%7D)
Sample size = n
Population standard deviation = ![\sigma](https://tex.z-dn.net/?f=%5Csigma)
The formula to calculate the standard deviation of distribution of sample means is:
![\sigma_{m}=\frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Csigma_%7Bm%7D%3D%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
From the above relation we can see that:
Standard deviation of the distribution of sample means is inversely related to the sample size. In inverse relation if one quantity increases the other will decrease. So, if the size of the sample is increased, the standard deviation of the distribution of sample means will Decrease.
Hence, the given statement is False. Therefore, the correct answer will be:
B. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases"

Part 1): 10³
Part 2): Ten cubed or
ten to the power of 3.
<u>Explanation </u>
Part 1
Figures written in exponent form means they should be in indices. That means they should be in power form.
10×10×10 = 10³.
Part 2
10³ ⇒ Ten raised to power 3. This can be written as ten cubed.
