<u>Answer:</u>
Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: <u>3,839,999,871</u>
Step-by-step explanation:
"Subtract" means to take away a number from another.
" 20 raised to the 7th power" is the same thing as 20 exponent 7:
SO, you want to take away 43 from and then multiply the answer by 3:
( - 43) × 3
1,280,000,000
(1,280,000,000 - 43) × 3
1,280,000,000 - 43 = 1,279,999,957
1,279,999,957 × 3
1,279,999,957 × 3 = <u>3,839,999,871</u>
There you go! I really hope this helped, if there's anything just let me know! :)
Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.
Step-by-step explanation:
Definitions:
- Null hypothesis
is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.
- Alternative hypothesis
is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.
Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.
If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.
i.e.
So,
The required null and alternative hypotheses:
H0: Mean= 5 and Ha: Mean is not equal to 5.
Answer:
A 12 mile ride in Taxi 1 costs $36.00, and in Taxi 2 it costs $34.20.
Step-by-step explanation:
Given that:
Charges of taxi 1 = $3.00 per mile
Charges of taxi 2 = $1.77 per kilometer
1 mile = 1.61 kilometers
To find:
Cost of a 12 miles ride for taxi 1 and taxi 2.
Solution:
Let us first convert the charges of each taxi to per mile.
Taxi 1 charges are already given in per mile.
Charges for 1 mile = $3
Charges for 12 miles = 3 12 = <em>$36</em>
Taxi 2 charges = 1.77 1.61 = $2.85 per mile
Charges for 12 miles = 2.85 12 = <em>$34.20</em>
<em></em>
Therefore, the answer is:
<em>A 12 mile ride in Taxi 1 costs $36.00, and in Taxi 2 it costs $34.20.</em>
