Records show that Oliver is typically 10-30 minutes late
Ratling [72]

The percentage of the time will Oliver get a written warning when  he is more than 16 minutes late for his shift at work is 46.7%.

<h3>What is a density curve?</h3>

The density curve is a type or way of representation of numbered distribution data over a graph. Here, the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.

In a density curve,

  • The mean of a density curve is indicated by μ (mu).
  • The standard deviation of a density curve is indicated by Sx.

Records show that Oliver is typically 10-30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.

Oliver will get a written warning if he is more than 16 minutes late for work. The time remain after the 16 minutes is,

t=30-16

t=14 min

Thus, the percentage of the time will Oliver get a written warning is,

p=(14/30)*100

p=46.7 %

Thus, the percentage of the time will Oliver get a written warning when  he is more than 16 minutes late for his shift at work is 46.7%.

Alex Ar [27]

Answer:

<h2>330 different possible selections are there.</h2>

Step-by-step explanation:

There is a total of 11 cut flowers.

Jeanine Baker has to choose 7 flowers among the 11 flowers.

The formula for choosing r numbers from n numbers is defined by ^{n}C_{r} = \frac{n!}{r!\times(n - r)!}, n > r.

From 11 flowers 7 flowers can be chosen in ^{11} C {7} = \frac{11!}{7!\times4!} = \frac{8\times9\times10\times11}{2\times3\times4}. = 330 ways.

There are 330 possible ways to choose 7 flowers from 11 flowers.
