Answer: The number of books she should put on each shelf = 7

Step-by-step explanation:

Given: Total books = 116

Total shelves = 16

To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.

116\div 16=7\dfrac14

So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.

Hence, The number of books she should put on each shelf = 7.

uysha [10]

Answer:

Step-by-step explanation:

Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.

i.e. X is normal with mean = 15 and unknown std deviation \sigma

Given thatP(X

i.e. P(z

z=-1.475 (from normal table)

Hence \frac{13-15}{\sigma}=-1.475\\\sigma = 1.356

Using this we find P(X>17) = P(Z>\frac{17-15}{1.356} \\=P(Z>1.475)\\=0.5-0.428\\=0.072

Please Help, I can't figure out this problem
Otrada [13]

Answer:

<h2>The answer is 5 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d  =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (9,-7) and (5, -4)

The distance between them is

d =  \sqrt{ ({9 - 5})^{2} +  ({ - 7 + 4})^{2}  }  \\  =  \sqrt{ {4}^{2}  +  ({ - 3})^{2} }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}

We have the final answer as

<h3>5 units</h3>

Hope this helps you
