Answer:
14 more flower would bloom if 21 more tulip bulb is planted.
Step-by-step explanation:
Given ratio for tulip bulbs and flowers is 15:10.
Now, finding number of flower to bloom if 21 tulip bulb are planted.
Assume if 21 tulip bulbs are planted then number of flower would bloom be"x"
ratio given: ![\frac{Tulip\ bulbs}{ Flower} = \frac{15}{10} = \frac{21}{x}](https://tex.z-dn.net/?f=%5Cfrac%7BTulip%5C%20bulbs%7D%7B%20Flower%7D%20%3D%20%5Cfrac%7B15%7D%7B10%7D%20%3D%20%5Cfrac%7B21%7D%7Bx%7D)
Cross multiplying the ratio to get:
⇒x= ![\frac{21\times 10}{15} = \frac{210}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B21%5Ctimes%2010%7D%7B15%7D%20%3D%20%5Cfrac%7B210%7D%7B15%7D)
∴![x= 14\ flowers](https://tex.z-dn.net/?f=x%3D%2014%5C%20flowers)
Hence, 14 flowers would bloom if 21 tulip bulb are planted.
If total tulip bulb is
, then
would bloom.

Answer:
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.
