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.
Answer:
9 and -4
Step-by-step explanation:
change the word form to math form so now
x² - 36 = 5x <u>This look like a factoring problem, so we put it equal to 0</u>
x² - 5x - 36 = 0 <u>Now factor</u>
(x - 9) (x + 4) <u>We have to find 2 numbers that give -36 when we multiply and -5x when we add</u>
x - 9 = 0
x = 9
x + 4 = 0
x = -4
you can check by plugin the x value to actual equation.
Use the attached formula.
Years = ln (200 / 100) / .034
Years = ln (2) / .034
Years = 0.69314718056 / .034

We know, nickel = 5 cents
& 1 dime = 10 cents,
So, money from nickel would be:= 5x
money from dime would be:= 10y
Total, money = 2000 cents ($20)
& You need to shade the area below the line for positive values of x and y.
By collecting all the datas from above, option C is your answer.
Hope this helps!
