To solve this problem you must apply the proccedure shown below:

1. You must calculate the perimeter of the circle:

The radius of the circle in inches is:

$radius=\frac{(10ft)(12in)}{1ft}=120in$

$P=2\pi(radius)\\ P=2\pi(120in)\\ P=753.98in$

2. Now, you must divide the perimeter by the space between each flower to find the number of flowers needed, which you can call $x$ :

$x=\frac{753.98in}{6in}=125.6=126$

The answer is: 126 flowers.

Eggs that are contaminated with salmonella can cause food poisoning among consumers. A large egg producer takes an SRS of 200 eg

Paladinen [302]

Answer:

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Step-by-step explanation:

The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.

In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.

Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Ginger make pies and sells them for $14 each. What equation if y represents the money and x represents the number of pies sold

BlackZzzverrR [31]

Answer:

y = 14x

Step-by-step explanation:

The equation is as follows:

Let us assume x be the number of pieces sold

And, the y be the money

Also the selling price be $14 each

So, the equation is

y = 14x

Create an exponential to describe $100 at 2% interest, compounded annually, for x years. y=100(.98)^x y=100(.8)^x y=100(1.2)^x y

zysi [14]

The exponential to describe $100 at 2% interest, compounded annually, for x years is $y=100(1.02)^{x}$

<h3><u>Solution:</u></h3>

Given that $ 100 at 2 % interest , compounded annually for "x" years

<em><u>The formula for compound interest, including principal sum, is:</u></em>

$A=P\left(1+\frac{r}{n}\right)^{n t}$

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here in this sum,

P = $ 100

$r = 2 \% = \frac{2}{100} = 0.02$

number of years = x

Here given that compounded annually , so n = 1

Let "y" be the amount after "x" years

Substituting the values in formula we get,

$\begin{aligned}&y=100\left(1+\frac{0.02}{1}\right)^{1 \times x}\\\\&y=100(1+0.02)^{x}\\\\&y=100(1.02)^{x}\end{aligned}$

Thus the exponential to describe is $y=100(1.02)^{x}$
