Answer:

The z-score is z  = 0.6

The percentile is  p(Z < 0.6) = 72.57\%

Step-by-step explanation:

From the question we are told that

   The  data value is  0.6 standard deviations above the mean i.e  x =  \mu + 0.6 \sigma

Where  \mu is the population mean and \sigma is the standard deviation

Generally the z-score is mathematically represented as

        z  =  \frac{x -  \mu }{\sigma }

=>     z  =  \frac{(\mu + 0.6\sigma ) - \mu }{\sigma }

=>    z  = 0.6

The percentile is obtained from the z-table and the value is

     p(Z < 0.6) = 0.7257

=>   p(Z < 0.6) = 72.57\%

The flower shop makes bouquets with ten flowers in each bouquet.
denis-greek [22]
I agree with with the florist because when you divide 207 by 10 you will get 20.7. This means that the florist could make 20 bouquets but seven flowers would be left out.
Hope this helps and please mark brainliest!

A &amp; B share the cost in a ratio of 3:2. A pays £125, how much does B pay?
guajiro [1.7K]
Let the common multiple be x
3x : 2x
3x = 125
x = 125/3

So, B pays 2x = 2 × 125/3 = £250/3

Please help! I must match the numbers on the left with all appropriate number sets on the right . A number on the left may match
Flura [38]

Answer:

\sqrt{5} = Irrational

6 = Natural, Whole, Integer, Rational

\frac{1}{2} = Rational

-2 = Integers, Rational

Explanation:

See attached photo! (it is hard to explain in words haha)

      Side note: All natural numbers are rational numbers, but not all rational numbers are natural numbers (this applies differently to all sections, like all integers are whole, but not all whole are integers, etc)

      Side note #2: Whole numbers are just natural numbers AND zero

Hope this is correct (or at least helps), have a nice day! :D
