Let X be a random variable representing the mean gray scale of each pixel.
P(110 ≤ X ≤ 140) = P(X < 140) - P(X < 110) = P(z < (140 - 125)/15) - P(z < (110 - 125)/15) = P(z < 1) - P(z < -1) = P(z < 1) - [1 - P(z < 1)] = 2P(z < 1) - 1 = 2(0.84134) - 1 = 1.68268 - 1 = 0.68268
Number of pixels that have gray scale of between 110 and 140 = 0.68268 x 1000000 = 682680 = approximately 680,000
It would take 6 days to consume a whole apple, so you multiply 6 by 3 to get your answer, 18 days :D
Answer:
<em>a = 1 ; b = - 8 </em>
Step-by-step explanation:
x² + 2x - 7 = (x² + 2x + 1) - 1 - 7 =<u><em> (x + 1)² - 8 </em></u>
<em>a = 1 </em>
<em>b = - 8</em>
Answer:
d) the numbers are 9 and 12
Step-by-step explanation:
set each factor equal to 108:
m-12=108
m = 120
*************
m-9=108
m=117
*************
120 and 117 are 3 units apart
****************
9 x 12 = 108
Hello :
<span>x^3-3x^2+2x=0
x(x²-3x+2) = 0
x(x-1)(x-2) = 0
x = 0 or x-1 = 0 or x-2= 0
x = 0 or x = 1 or x = 2
