Create a linear regression equation that can be used to model the amount of money in the account (the balance), y, based on the
Karolina [17]

The regression equation is \^y = 1.56\^x + 1.29, and it will take 31 weeks to have $50.00

<u>(a) The linear regression equation</u>

To do this, we make use of a graphing calculator;

From the graphing calculator, we have the following calculation summary:

  • The sum of X = 45
  • The sum of Y = 83
  • Mean X = 4.5
  • Mean Y = 8.3
  • Sum of squares (SSX) = 82.5
  • Sum of products (SP) = 128.5

The regression equation is then represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = M_Y - bM_X

So, we have:

b = \frac{128.5}{82.5}

b = 1.55758

Approximate

b = 1.56

a= 8.3 - (1.56 \times 4.5)

a= 1.29091

Approximate

a= 1.29

This means that, the regression equation is \^y = 1.56\^x + 1.29

<u>(b) Predict the time to have $50.00</u>

This means that:

\^y = 50

So, we have:

50 = 1.56\^x + 1.29

Subtract 1.29 from both sides

48.71 = 1.56\^x

Divide both sides by 1.56

31.22 = \^x

Rewrite as:

\^x = 31.22

Approximate

\^x = 31

Hence, it will take 31 weeks to have $50.00

A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 o a kilometer away from a pond. At this speed,how long will
eimsori [14]

Answer:

It will take 5/12 hours.

Step-by-step explanation:

Given,

The speed of turtle = \frac{1}{12} km per hour,

Distance covered = \frac{1}{5} km,

Since,

Speed =\frac{Distance}{Time}

\implies Time =\frac{Distance}{Speed}

Hence, the speed of turtle = \frac{\text{1}{12}}{\frac{1}{5}}

=\frac{5}{12} hour.
