Which of the following exponential regression equation best fits the data shown below. Please help ASAP. ☺️
stepladder [879]

Answer:

Option D [y=6.61\,*\,1.55^x] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

y=A\,e^{k\, x}

with optimized parameters:

A \approx 6.6114\,\,\,and\,\,\, k=0.4378321

Notice as well that since:

e^{0.4378321} \approx 1.5490

the exponential best fit can also be written:

y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}

and this expression is very close to the last option shown in your list of possible answers

the ratio of black bags to blue bags is 5 to 3. If there are a total of 185 black bags, then how many blue bags are there?
nlexa [21]

Answer:

There are 111 blue bags

Step-by-step explanation:

Let

x ----> the number of black bags

y ---> the number of blue bags

we know that

\frac{x}{y}=\frac{5}{3}

isolate the variable y

y=\frac{3}{5}x -----> equation A

x=185 ----> equation B

substitute equation B in equation A

y=\frac{3}{5}(185)

y=111

therefore

There are 111 blue bags
