Answer:
Missing number is 1
Step-by-step explanation:
3(2x+1)
Using distributive property,
=>3(2x)+2(1)
=>6x+2
Answer:
(a) The confidence interval is: 0.0304 ≤ π ≤ 0.0830.
(b) Upper confidence bound = 0.0787
Step-by-step explanation:
(a) The confidence interval for p (proportion) can be calculated as
NOTE: π is the proportion ot the population, but it is unknown. It can be estimated as p.
For a 95% two-sided confidence interval, z=±1.96, so
The confidence interval is: 0.0304 ≤ π ≤ 0.0830.
(b) The confidence interval now has only an upper limit, so z is now 1.64.
The confidence interval is: -∞ ≤ π ≤ 0.0787.
Answer:
1/15
Step-by-step explanation:
You have a 1/3 chance of being an elf.
You have a 1/5 change of having the magic tool.
1/3 × 1/5 = 1×1/3×5 = 1/15
Answer:
the fraction of the USB drive when one video file use is 10%
Step-by-step explanation:
The computation of the fraction of the USB drive when one video file use is given below:
= USB drive × number of video file ÷ number of video file
= half × 1 ÷ 5
= 0.5 × 1 ÷ 5
= 0.10
= 10%
Hence, the fraction of the USB drive when one video file use is 10%
Answer:
0.0057
Step-by-step explanation:
- Narrow it down.
- The point P is between 5 * 10^-3 and and 6*10^-3
- When you go to the bottom line, P is on the 7th division from the left.
- Going from left to right increases P
- P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
- One of the answers is 5.7 * 10^-3
- The other answer is .0057
- I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
- If it is not correct, then 5.7 * 10^-3 is the answer.
