Data Was Recorded For The Temperature, In Degrees Celsius, Of A Cup Of Coffee Over A 30-minute Period.

Answers

Answer 1

Answer:

62.24

Step-by-step explanation:

Answer 2

The predicted temperature after 3 minutes will be 62.24 °C. Then the correct option is B.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

A cup of coffee's temperature was measured over a 30-minute period in degrees Celsius.

Let T be the temperature and t be the time. Then the regression equation is given as,

ln T = 4.20 - 0.023 t

Then predicted temperature after 3 minutes is given as,

ln T = 4.20 - 0.023 x 3

ln T = 4.20 - 0.069

ln T = 4.131

T = 62.24 °C

The predicted temperature after 3 minutes will be 62.24 °C. Then the correct option is B.

4. Ty    5. Store A

Step-by-step explanation:

4. 750/3 is 250,  800/4 is 200, and 950/5 is 190 so i think it would be Ty

         Andre           Rick                        Ty

5. for Store A- 4 pairs of jeans is $120 so if you divide that which is 120/4 it gives you 30 so it would mean your paying $30 for each pair of jeans

for Store B- 2 pairs of jeans  will cost you $100 so if you add 50+50 it gives you a hundred so it means your paying $50 for each pair of jeans

for Store C- 3 pairs of jeans is $99 so if you divide 99/3 its 33 which means you would be paying $33 dollars for each pair of jeans

so out of all of then Store A gives you the best deal.

Write the equation in function form:
8x + 4y = 20

Answers

The answer is f(x) = 5 - 2x

Function form means just replace y with f(x).

So given 8x + 4y = 20:

Subtract 8x
4y = 20 - 8x

Divide both sides by 4
y = 5 - 2x
