Answer:
32.54%
Step-by-step explanation:
To determine the probability that an individual song has a danceability of at least 0.7
Applying the excel formula below
=COUNTIF ( I2:I4771,">0.7") / ROWS( I2:I4771)
Hence ; The probability of an individual song having a danceability of at least 0.7 = 32,54%
Answer:
56 mins
Step-by-step explanation:
Number of gallons of water in the pool per minute;
750 divided by 35 = 150/7
Let the time needed to fill a 1,200 gallon pool be t.
t x 150/7 = 1,200
t x 21.42857142857143... = 1,200
t = 1,200/21.42857142857143
t = 56 mins
Answer:
The first part is C) The increase in loudness per centimeter is the same for both
The second part is A) Thor's
Step-by-step explanation:
First part:
<u>Whose loudness increases more per additional centimeter of height?</u>
C) The increase in loudness per centimeter is the same for both
Second part:
<u>Whose strike is louder when he strikes from a height of 40 centimeters?</u>
A) Thor's
I did it on Khan and it was correct.
Answer
5 and a half
Step-by-step explanation:
or 
is very easy to graph.
Choose whatever value of 
and use the same for 
in the same coordinate. Repeat and strike a line through all the points.
Some examples of valid points would be: 
, 
, 
and 
.
Then, to graph 
you have to look at it in terms of the equation of a line (
) and its parts.
In this case, 
and 
.
So, you choose any value for and you solve to find its counterpart.
I will start with 
:
Now, we have a first coordinate: 
.
Repeat with a different value:
It gives us the coordinates 
.
Plot those into the graph and strike a line through them.
Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be 
.
You can check it by replacing and by "3" in both formulas and equating the values of :
Your solution is worked out and checked to be correct.
PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
