↪Actually welcome to the concpet of the Rate of change of any Quantity with respect to time. ..
↪since for general we know that ..
↪Rate of change = ( Final state - initial state )÷( final time - initial time )
↪thus ♢d = (A2 - A1) ÷ (t2 - t1)
↪applying the formula above we get as ..
↪Rate of change of water level in feet per hour =
↪======> (Water level final - Water level initial ) ÷ ( final time - initial time )
↪since here we can take any interval of time ... we choose the second and third ..
↪thus Rate = (30 - 40 ) ÷ ( 4 -2 )
↪==》 Rate = -10 ÷ 2 ==》 -5 feet/ hr
↪since the rate cannot be negative value , we take the modulus of it
↪this Rate = |-5| = 5
↪thus Rate = 5 feet / hour

Answer:
Median = 31
Step-by-step explanation:
The median is the middle number which comes after arranging the set in ascending order.
Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20
The data arranged in the ascending order is as follows:
12, 19, 20, 28, 34, 36, 45, 45
Since the number of terms is even, we have two middle numbers, viz.,
28 and 34
The median would be the average of these two.
Therefore, Median =
= 31
The answer is 31.
Answer:
The correct option is C) $145,000
Step-by-step explanation:
Consider the provided regression.
sales y in $1000 and advertising x in $100
We have given that they spent $900 in advertising.
That means substitute x=9 in above regression because x is in $100.
It is given that y in $1000.
That means the total sale is 145×$1000=$145000.
Hence, the correct option is C) $145,000
wish I could help but don't now whatn you are saying
Perimeter = 2L + 2W where L = length and W = width.
So we have
2*14.14 + 2W = 59.59
2W = 59.59 - 2*14.14
2W = 59.59 - 28.28 = 31.31
W = 31.31 / 2 = 15.66 to 2 decimal places
