Find the Exponential Regression using the table. Write the initial amount, common ratio, and equation for the table.
Ipatiy [6.2K]

Answer:

Initial amount;

2110.6

Common ratio;

0.0201

Equation;

y=2110.6e^{0.0201x}

Step-by-step explanation:

In this scenario, the  month represents the independent variable x while the membership amount represents the dependent variable y.

The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.

The Ms. Excel output is shown in the attachment below. To obtain the initial amount we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.

A number divided by eleven.
Sliva [168]

Answer:

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Two fair coins are flipped. Given that at least one coin lands on a head, calculate the probability of one head and one tail. Wr
Greeley [361]

The probability of one head and one tail is 2/3.

<u>Step-by-step explanation</u>:

  • The possibilities for flipping two fair coins are {T,T}, {H,H}, {H,T}, {T,H}
  • Given the case that at least one coin lands on a head, So the total possibilities are {H,H}, {H,T}, {T,H} = 3 possibilities
  • Required event is 1 head and 1 tail= {H,T}, {T,H} = 2 possibilities

To calculate the probability of one head and one tail,

Probability = required events / Total events

Probability = 2/3

Graph the system of equations on your graph paper to answer the question. {y=x−4y=−x+6 What is the solution for this system of e
arsen [322]

Answer:

(5,1)

Step-by-step explanation:

Given :

y=x-4\\y=-x+6

Solution :

Equation 1 : y=x-4

Equation 2 : y = -x+6

We will use substitution method

Putting the value of y from equation 1 in equation 2

⇒x-4 = -x+6

⇒x+x= 6+4

⇒2x=10

⇒x=\frac{10}{2}

⇒x=5

Now substituting value of x in equation 1 to get value of y

⇒y=x-4

⇒y=5-4

⇒y=1

Thus the solution of given system of equations is (5,1)

We have also solved it by graphing the equations

You can refer the attached figure.
