About 32.34% of the values do not lie between the z-scores of -1.3 and 0.75.

First, we need to find the region between the z-scores.

If you look at a normal distribution table, you will get the following values:

0.75 = 77.34%
-1.3 = 9.68%

Subtraction those gives us the area between the z-scores.
77.34 - 9.68 = 67.66%

Now, just subtract that value from 100% to get the amount outside of the area.
100 - 67.66 = 32.34%

The lengths of the sides of a triangle are 5, 12, and 13. What is the length of the altitude drawn to the side with length equal
mario62 [17]

Answer:  using  A= bh/2   THe height is 9.23

Step-by-step explanation:  First, with the Right Angle at the bottom, usr the sides to compute the area:  12*5=60

THen Imagine the side=13 as the base, so you have  b=13 for the formula

use the formula A= bh/2

60 = 13h/2 ==> 2(60) =13h --> 120/13 = h

h = 9.23

What value is needed to complete the square? Show all steps. <br> x^2 - 2x +__
Sunny_sXe [5.5K]

In completing the square method, considering the equation X^2 - 2x +  the number to be added should be<u> 1 </u>to make it a perfect square

<h3>How to know term that should added</h3>

The standard quadratic equation is of the form

ax^2 + bx + c

The completing the square method is one of the methods of solving quadratic equations

The factor to be added to the equation while using the completing the square method is of the formula

(b / 2a)^2

compared to the equation in the problem X^2 - 2x +

= (b / 2a)^2

= (2 / 2)^2

= (1)^2

= 1

the width of a rectangle is 9m less than it's legnth if the perimeter of the rectangle is 54m find the legnth of the garden​
Nata [24]

Perimeter of rectangle = 2(l+w)

So, 54cm = 2(l+9cm)

=> 54cm = 2l + 18cm

=> 54cm - 18cm = 2l

=> 36cm = 2l

=> 36cm/2 = l

=> 18cm = l
