If 12 is replaced with 3 in the following set, what will happen to the value of the range? 28, 45, 12, 34, 36, 45, 19, 20

anzhelika [568]

The range is the number of units between the smallest and largest number. organising your numbers from smallest to largest:

12, 19, 20, 28, 34, 36, 45, 45

in your case 12 is the smallest number of your set. lowering it to 3 would increase the distance between the two numbers, therefore increasing the range

hope that helps :)

Let the universal set, s, have 66 elements. a and b are subsets of s. set a contains 19 elements and set b contains 34 elements.

Otrada [13]

The cardinality of the union between two sets is given by

$N(A\cup B) = N(A) + N(B) - N(A \cap B)$

In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are

$N(A \cup B) = 19+34-10 = 43$

This means that the two sets cover, without repetitions, 43 of the 66 elements in the sets. So, there are

$66-43 = 23$

elements which are in neither A nor B

Fill in the blanks:

Murrr4er [49]

Let

x--------> the length side of the rectangle

y--------> the width side of the rectangle

we know that

The perimeter of a rectangle is equal to

$P=2x+2y$

$x=(4a + 96)/(a + 15)$

$y=(4a + 24)/(a + 15)$

Substitute the values of x and y in the formula of perimeter

$P=2*[(4a + 96)/(a + 15)]+2*[(4a + 24)/(a + 15)]$

$P=[(8a + 192)/(a + 15)]+[(8a + 48)/(a + 15)]$

$P=[(16a + 240)/(a + 15)]$

$P=16*[(a + 15)/(a + 15)]$

$P=16\ m$

therefore

<u>the answer part a) is </u>

the total length of fencing material required would be $16\ m$

Part b) Divide the perimeter by the width of the prebuilt fence sections

so

$\frac{16}{0.50} = 32\ sections$

therefore

<u>the answer Part b) is </u>

$32\ sections$
