All you have to do is just put a number for x...so for the first one you could do x=8, because 8 is less that 9. For the second one you could do x= 10, because 10 is greater than 6

MAXImum [283]

Answer:

XAW = 3(23) = 69 degrees.

WAY = 23 + 88 = 111 degrees.

ZAY = 8(12) - 23 = 73 degrees.

XAZ = 6(12) + 35 = 107 degrees.

a. Nick deposits money in a Certificate of Deposit account (CD). The balance (in dollars) in his account t years after making th

ANEK [815]

Answer:

(1.06)0 = 1 and positive powers of 1.06 are larger than 1, thus the minimum value N(t) attains, if t≥0, is 400.

From the point of view of the context, a CD account grows in value over time so with a deposit of $400 the value will never drop to $399.

Maranda is buying pencils and a writing pad for her adult writing class. The writing pad she wants costs $3.50, and each pencil

Kruka [31]

Hello!

3.50 + 0.15 = 3.65

Because both items would cost $3.50 together, Maranda will be eligible to buy them both and stay within her budget of $5.00.

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.
