Consider the probability that at least 93 out of 154 CDs will not be defective. Assume the probability that a given CD will not
Yuki888 [10]

Answer:

0.5962

Step-by-step explanation:

Given that :

p = 61% = 0.61

q = 1 - p = 1 - 0.61 = 0.39

n = 154 ; x = 93

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x>=93) = p(x=93)+p(x=94)+...+p(x=n)

P(x>= 93) = 0.59619

P(x>= 93) = 0.5962

PLS HELP ME ASAP WITH 1!
Vlad1618 [11]
All of these make use of the expansion
   (a + b)² = a² + 2ab + b²
You would do well to memorize this "formula." Of course, it also helps to be able to double (or halve) a number, and to know the squares of small integers.

1.
   x² +2x +1
   x² -6x +9
   x² +12x +36
   x² -0.4x +0.04
   4x² +28x +49
   9x² +30x +25

2.
   (x + 4)²
   (x + 3)²
   (x - 9)²
   (x - 5)²

3. (12/2)² = 36

4. ±2√49 = ±14

THANKS IF YOU ANSWER,
Yakvenalex [24]
ANSWER: 114ft^2


Area of cabinets = (4*2)+(4*2) = 16ft^2

Area of kitchen = (10*13) = 130ft^2


Subtract area of the cabinets from total area


130ft^2 - 16ft^2 = 114ft^2

Hello, can someone help with this problem?
Vera_Pavlovna [14]

Answer:

P(5 ≤ X ≤ 8)  = a  rectangle  with a width of 3  and height of .15   = 3(.15)  = .45

 

P( 4 ≤ X ≤ 5)  =  a triangle  with a base of 1  and a height of (0.15 -0.05) = .10

So....this area  =   (1/2)(1)(.10)  = .05

 

And  another rectangle with a width of 1 and height of .05  = (1) (.05) = .05

 

So

 

Adding these areas

 

P( 4 ≤ X ≤ 8 )  =  .45 + .05 + .05   =  .55

Step-by-step explanation:
