Answer:
set c is the answer
Step-by-step explanation:
for a pair to be a function it can't have 2 different numbers for the same x value
Answer:
{3, 4, 5, 6, 7, 8, 9, 10, 11}
Step-by-step explanation:
Let integer be x
x > 2 and x < 12
gives
2 < x < 12
All such integers are {3, 4, 5, 6, 7, 8, 9, 10, 11}
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:
The better bargain is the case of twelve 12 ounce cans.
Step-by-step explanation:
<u>2-liter bottle of soda:</u>
67.6 ounces cost $1.89, then
1 ounce costs
<u>A case of twelve 12 ounce cans:</u>
ounces of the same soda cost $2.99, then
1 ounce costs
The better bargain is the second choice, the case of twelve 12 ounce cans.
