Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which t

Svetllana [295]

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:

$y=\alpha +\beta x$

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:

$y=4.40-0.01\ x$

Here,

y = reaction time (in hours)

x = temperature (°F)

Compute the expected change in reaction time for a 1°F increase in temperature as follows:

$y=4.40-0.01\ (1^{\text{o}})$

$=4.40-0.01\\=4.39\ \text{hours}$

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:

$y=4.40-0.01\ (8^{\text{o}})$

$=4.40-0.08\\=4.32\ \text{hours}$

The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.

Marco needs to buy some cat food. At the nearest store, 2 bags of cat food cost $11.50. How much would Marco spend on 6 bags of

pochemuha

Answer:$34.50

Step-by-step explanation:

First of all you’re gonna wanna know the total amount for ONE bag of cat food. so divide

11.50/2= 5.75

now add OR multiply (it doesn’t matter) 5.75 six times.

5.75x6= 34.5

hope this helped

Miranda has 3 kites. Each kite needs 4 2/3 yards of string. How much string does Miranda need for all 3 kites?

Alekssandra [29.7K]

Answer:

14 yards of string.

Step-by-step explanation:

Since each kite needs 4 2/3 yards of string and there are 3 kites, we have to multiply 4 2/3 by 3.

So, 4 2/3 × 3 = 14.
