Answer:

1 Quarter is one fourth of Dollar.

And, 1 Dime is one tenth of Dollar.

Number of Coins in Ben's Bag=15 coins

Number of Quarters=7

So, number of Dimes

=15-7=8

Total amount in Dollars

   =\frac{1}{4}\times7+\frac{1}{10}\times8\\\\=\frac{7}{4}+\frac{8}{10}\\\\=1.75+0.80\\\\=2.55$

In Words=Ratio of $2.55 to 7 Quarters that is $1.75 will be ?

Ratio in two different ways

   \rightarrow \frac{2.55\text{Dollars}}{1.75\text{Dollars}}=\frac{51}{35}=\frac{102}{70}

Let's compare the whole coin collection to the quarters.

One way to represent the ratio is 15 : 7.

The other way is \frac{15}{7}

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.
