Pi is an irrational number meaning it has no end, 3.14 is just an estimate which means that it is not accurate.

Which number is greater than the absolute value of -5/9 A -1. B -2/3. C 7/4. D 4/7. And how ?

Kaylis [27]

the absolute value of -5/9, written |-5/9|, = 5/9.

Checking:-

5/ 9 = 0.55...

4/7 = 0.57

7/4 = 1.75

So C and D are greater than absolute value of -5/9.

"The length of a rectangle is 5/2 units greater than its width"

'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is $\sf\dfrac{5}{2}w$ .

Perimeter of a rectangle is:

$\sf P=l+w$

Plug in our value for the length:

$\sf P=\boxed{\sf \dfrac{5}{2}w+w}$

A lot of 9 components contains 3 that are defective. Two components are drawn at random and tested. Let be the event that the fi

kirza4 [7]

Answer:

Probabilty of first component drawn defective= 0.1161

Probability of second component drawn defective= 0.1560

Step-by-step explanation:

Total component = 9

Defective component= 3

Non-defective component= 6

Probability of defective= 3/9

= 0.3333

Probabilty of non defective= 1-0.3333

= 0.6666

Probabilty of first component drawn is defective

= 9C1(0.333)¹(0.6666)^8

= 9(0.3333)(0.0387)

= 0.1161

Probabilty of second component is defective

= 8C1(0.3333)¹(0.6666)^7

= 8(0.3333)(0.0585)

= 0.1560
