The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of 
is 0. So = 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x = 
= -3.
So the other number is -3.

Answer:
Y= 5x + 17
Step-by-step explanation:
Y-y1= m(x-x1)
Y- -3= 5(x- -4)
Y+ 3= 5x +20
Y= 5x + 17
Answer:
The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.
The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.
Step-by-step explanation:
The simple linear regression line is used to determine the changes in the dependent variables when the independent variable is changed.
The general form of the simple linear regression line is:
The simple linear regression model for the reaction time of a certain chemical process based on the temperature (°F) in the chamber in which the reaction takes place is:
Here,
<em>y</em> = reaction time (in hours)
<em>x</em> = temperature (°F)
Compute the expected change in reaction time for a 1°F increase in temperature as follows:
The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.
Compute the expected change in reaction time for a 8°F increase in temperature as follows:
The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.
