317,362 x 129,324<br> Is it even or odd

Anna35 [415]

Answer:

41,042,523,288 It is even.

Step-by-step explanation:

To tell whether a number is even or odd, look at the number in the ones place. That single number will tell you whether the entire number is odd or even. An even number ends in 0, 2, 4, 6, or 8. An odd number ends in 1, 3, 5, 7, or 9.

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm

Ket [755]

<h3>Answer: 168 square cm</h3>

==============================================

Work Shown:

L = 2 = length
W = 6 = width
H = 9 = height

The order of length, width and height doesn't matter

SA = surface area of rectangular prism

SA = 2*(LW + LH + WH)

SA = 2*(2*6 + 2*9 + 6*9)

SA = 2*(12 + 18 + 54)

SA = 2*(30+54)

SA = 2*(84)

SA = 168 square cm

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,

<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:

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

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

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.
