Answer:
-0.125
Step-by-step explanation:
Okay to solve this problem you would simply do this solution. It took me a minute, haven't had to do integers in a while. :D
From 10,000 to 99,999 the numbers divisible by 5 ends in 0 or 5.
The first (most significant) digit can be any of nine from 1 to 9.
The 2nd digit can be any of 10.
The 3rd digit can be any of 10.
The 4th digit can be any of 10.
The 5th digit can be either of 2.
<span>That's 9(10)(10)(10)2=18,000

I hope this helps.
Answer:
factors are basically numbers that can multiply by another number to get a certain number
Step-by-step explanation:
for example, the factors of 12: 1,2,3,4,6,12
you should count from the lowest to highest number to make it easier for u.
look at 1 and 12 in the sequence. 1 x 12 = 12
now look at 2 and 6. 2 x 6 = 12
now look at 3 and 4. 3 x 4 = 12
see what i mean?
an example of a non-factor would be 5. 5 can't multiply by anything to get 12. You need to find numbers between 1 and the certain number (12 in this example) and you need to find numbers that can multiply by another number to get that certain number but u can't go beyond the certain number. 7 can't multiply by anything to get 12. if u still don't understand, here is an easier way to help u.
the best thing to do is write the numbers from 1 - 12. 1 2 3 4 5 6 7 8 9 10 11 12
once u do that, you need to ask yourself: which numbers can multiply to get 12? 1 can multiply by a number to get 12. 2 can. 3 can. 4 can. <em>5 can't. </em>once you find a number that you can't multiply by, that is <em>not </em>a factor of the certain number you're looking for.
Hope this helps you :D
Answer:
P ( x_bar > 335 ) = 0.9826
Step-by-step explanation:
Given:
- Mean amount u = 350
- standard deviation s.d = 45/year
- Sample size n = 40
Find:
- The probability of sample mean P( x_bar > 335 )
Solution:
- P ( x_bar > 335 ) = P ( Z > sqrt(n)*(x_bar - u)/s.d)
= P ( Z > sqrt(40)*(335-350)/45)
= P ( Z > -2.111) = P ( Z < 2.111)
= 0.5 + P( 0 < Z < 2.111)
= 0.5 + 0.4826
= 0.9826
