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
-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.

Fatimah is driving at 1.5 km in 2 min. What is distance she covered in 2 1/4 h?
Answer:
101.25 km
Step-by-step explanation:
To solve, we need to first find how much she drives in one minute and then multiply that by the number of minutes she drives.
1.5 km = 2 minutes
divide both sides by 2.
1 minute = 0.75 km
2.25 hours = 2.25 * 60 = 135 minutes
Multiply the speed by the time to find distance.
135 * 0.75 = 101.25 km
Thus, she covered 101.25 km in 2 1/4 hours.

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
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.

Radius: 7 cm, Diameter: 14 cm
Step-by-step explanation:
Correct me if I'm wrong, but I understood that 14 cm is the length of the line segment drawn across the circle. We know that the definition of the diameter is "any straight line segment that passes through the center of the circle and whose endpoints lie on the end of each circle", which can be defined as the line that is shown with a length of 14 cm. It is also known that the radius, a line drawn from the center of the circle to an endpoint, is always half of the diameter, which in this case is 14 cm, so the radius would be 7 cm.

20+(5 x 2/5) + 3
Answer:
25.
Step-by-step explanation:
Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS
ParenthesisExponentiation (exponents)Multiplication/DivisionAddition/Subtraction**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**
First, we solve what is in parenthesis.
20+(5 x 2/5) + 3
5/1 x 2/5 = 10/5 = 2 (simplified)
Then, replace the equation with the answer.
20 + 2 + 3
Secondly, there are no exponents.
There is no multiplication nor division.
However, there is addition.
20 + 2 + 3
20 + 2 = 22
Now, we solve the remaining addition problem.
22 + 3 = 25.
Therefore, 20+(5 x 2/5) + 3 = 25.
