Subtract 69000 from 60000. Answer becomes 9000. So you add 9000 to 69000 2 times. Your answer becomes 87000.
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
1. Page 1-9 (1digit/page
x 9page) = 9 digits = 9 page
2. Page 10-99 (2digits/page x 90page)= 180 digits = 90 page
3. Page 100-999 (3digits/page x 900page)= 2700 digits = 900
page
2,929 total digits – (9 digits + 180 digits + 2700 digits)= 40
digits
Since there are only 4 digits after page 999 we divide 40/4
= 10, thus there are 10 more pages after 999
So the book has 1009 pages.
Hope
this answer will be a good help for you.

Answer:
Step-by-step explanation:
Given that the mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
X is N(25, 1)
a) Normal curve is in the attached file
b) the probability that a randomly selected fertilized egg hatches in less than 23 days
=
we convert x into Z score and use std normal distn table to find probability
i.e. we can say only 2.5% proportion will hatch in less than 23 days.
