The exponential regression equation that fits the data is:

[tex]y = 4.981 \times 2.674^x[/tex]

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Exponential regression is a statistical method used to model relationships between two variables, where one variable is the exponent of another.

In this case, we have two variables, X and Y, and we want to find an exponential function that best fits the data.

The general form of an exponential function is [tex]y = a \times b^x,[/tex]

where a and b are constants.

To find the exponential regression equation that fits the data, we need to find the values of a and b that minimize the sum of the squared errors between the predicted values of Y and the actual values of Y.

Using a software program or a calculator with regression capabilities, we can input the data and find the values of a and b that best fit the data.

In this case, the exponential regression equation that fits the data is:

[tex]y = 4.981 \times 2.674^x[/tex]

This equation has an R-squared value of 0.995,

which indicates a very good fit between the data and the exponential model.

Thus,

The exponential regression equation that fits the data is:

[tex]y = 4.981 \times 2.674^x[/tex]

Knowing that correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation -- which of the following correlation coefficients would represent the strongest correlation?
0.02
0.87
-0.5
-0.97

Answers

Answer: -0.97

Explanation:
-0.97 is the closest number to -1 or 1.

-0.97 has the strongest correlation. Therefore, option D is the correct answer.

What is the correlation coefficient?

The correlation coefficient describes how one variable moves in relation to another. A positive correlation indicates that the two move in the same direction, with a value of 1 denoting a perfect positive correlation. A value of -1 shows a perfect negative, or inverse, correlation, while zero means no linear correlation exists.

Given that, correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation

From the options -0.97 is closer to -1

Thus, -0.97 has the strongest correlation

Therefore, option D is the correct answer.

To celebrate her birthday, Whitney wants to take her friends adventuring in a 4WD vehicle from All Terrain Tours.


The vehicle can only carry 1700 pounds in total weight. Whitney calculates that the average weight of her friends is 165 pounds. She also thinks that she will need to pack 400 pounds of snacks, drinks, safety equipment etc. Whitney also understands that each person will carry 10 pounds of their own personal gear.


How many friends can Whitney invite?


Write an equation to help you figure out how many friends Whitney can invite to go adventuring with her. Use f as your variable for friends.
PLEASE HELP ASAP

Answers

Answer:

Whitney can bring 6 friends.

Step-by-step explanation:

The reason why is this:

Whitney is bringing 400 pounds of things plus her own body weight!

400 + 165 = 565 pounds

Now we add on Whitneys freinds which is 165 (their body weight) + the 10 pounds of gear which equals 175 pounds. So each friend would be 175 pounds total weight.

175 x 6 = 1,050 pounds

If we add on Whitneys total weight thats:

565 + 1,050 = 1,615

Adding on another friend would be 1,790 pounds which would be over the weight limit for the vehicle.

Hence, Whitney can bring along 6 friends for her birthday.

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?

39
40
73
91

Answers

B. 40

As we know Sid has 26 Caps

we also know that 26 is 65% of total

so let total caps = x

to calculate x

we know that percent = (Values*100)/total Values.......... i

and here Value = 26 caps

percentage = 65

So we have

65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i

65x= 2600x = 2600/65x=40 caps

Hence Answer is 40
