To solve this problem you must apply the proccedure shown below:
1- You must apply the following formula:

Where
is the residual,
is the observed value
and
is the predicted value
.
2- You only need to substitute the
into the equation
and then, you must apply the formula for calculate the residual:


The answer is: The residual is 
We let k be the proportionality constant for the relationship between number of hours, h and speed of the walker, s.
h = k/s
Substituting the known values,
12 = k/5
k = 60
For the second scenario,
h = k/s
Substituting the calculated value for k and the given value for speed,
h = (60)(3 miles/hour)
h = 20 hours
h = 20 hours
Therefore, it will take 20 hours to walk with a speed of 3 miles per hour.
It is an application of Pythagorean Theorem
And it is clear that the lower angle is 30 and the apex angle is 60 (this is how always normal TVs look like) ... refer to the image I attached
So, to calculate the width and the length:


You can after that round the length to be 22.517 in
Hope you got the idea
A=Adam
m= Melissa
a+m = 32
m= 3a
Then 3a + a = 32 or 4a =32 then a = 8
Answer: The correct option is first, the number of basketball hoops did the company previously produce to make the same profit is 1.3 million hoops.
Explanation:
Let the number of basketball hoops did the company previously produce to make the same profit be x.
Total Revenue = Price * Quantity
The total revenue in million dollars is,


The total cost in million dollars is,
Total Cost = One unit cost * Quantity

Profit = Total Revenue - Total Cost

The profit is 15 million.


The value of x is 1 and
.
The production is always positive therefore the value of x either 1 or 1.3. Since 1 million is not available in the options therefore the the correct optin is 1.3 million hoops.
