2 dogs/ 3 cats and 10 dogs/ 15 cats are an example of
b. Equivalent ratios
__________________________
![\frac{10 \: dogs}{15 \: cats} = \frac{5 \times 2 \: dogs}{ 5 \times 3 \: cats} = \frac{2 \: dogs}{3 \: cats} \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%20%5C%3A%20dogs%7D%7B15%20%5C%3A%20cats%7D%20%20%3D%20%20%5Cfrac%7B5%20%5Ctimes%202%20%5C%3A%20dogs%7D%7B%205%20%5Ctimes%203%20%5C%3A%20cats%7D%20%20%3D%20%20%5Cfrac%7B2%20%5C%3A%20dogs%7D%7B3%20%5C%3A%20cats%7D%20%20%5C%5C%20)
We can see that they are equivalent ratios.
Answer: C on edge
Step-by-step explanation:
A Z-score helps us to understand how far is the data from the mean. The correct option is B.
<h3>What is Z-score?</h3>
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
![Z = \dfrac{X- \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cdfrac%7BX-%20%5Cmu%7D%7B%5Csigma%7D)
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The weight of a randomly selected pack of gum has a z-score of 3.11. Therefore, The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.
Hence, the correct option is B.
