Answer:
1/18 of an hour OR 3.333
Step-by-step explanation:
Given that :
Time taken to read 6 pages = 1/3 of an hour
It takes equal amount of time to read each page ;
Hence, the tune take to read each page of the book is :
Total time taken / total number of pages
1/3 ÷ 6
1/3 * 1/6
= 1/18 of an hour
= 1/18 * 60
= 3.3333
Answer:
answer:
(-3, -8)
Step-by-step explanation:
Answer: a) 6
<u>Step-by-step explanation:</u>
The mean is 375 which has a z-score of 0.
The standard deviation is 24 so:
- z-score of 1 is: 375 + 24 = 399
- z-score of 2 is: 399 + 24 = 423
- z-score of 3 is: 423 + 24 = 477
A z-score of 3 is 99.85% from the left <em>(or 1 - 99.85% from the right = 0.15%)</em>
Since we are looking for the "more than" a z-score of 3, it is 0.15% of the total.
4000
<u>× 0.0015</u>
6.0000
The answer would be 9 you would add the 13 and 7 then have 20-5t=-25 then subtract 20 from 25 then you would have -5=-45 which is 9
