Answer:
Add all the values up and divide by 7 ( as there are 7 values in the data set)
Step-by-step explanation:
1.9 + 10 + 11 + 16 + 12 + 12 + 14 = 76.9
If you divide by 7, you will get 10.9857142857.
If there are two songs written and the longest one is 126 seconds less than twice the length of the short song, and the longest one lasts 286 seconds, then the shorter song's length can be found using this formula:
2x-126=286.
This would then turn into x-63=143 to show the time difference. Solving here for x, would be 206 seconds.

Hello!</h2>
The answer is:
The correct option is the option D

<h2>
Why?</h2>
To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:

Where:
is the final speed.
is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:



Then, using the formula to isolate the acceleration, we have:


Now, substituting we have:


Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:

Hence, the correct option is the option D

Have a nice day!
Answer:
About 23.9 in
Step-by-step explanation:
We are given ;
a circle whose radius is 3.8 inches
we are required to determine the circumference
The circumference is given by the formula;
=2πr
Therefore;
Circumference = 2×3.14×3.8 in
=23.864 in
= 23.9 in
Therefore, the circumference of the figure is about 23.9 in
