What is the length of BC?<br><br> ___units?

san4es73 [151]

Supposing AC and AB are the same length we can solve this by equating these two expressions to each other;

2x - 24= x -2

x=22

Since the missing side BC equals "x" then BC = 22

The length of ribbon A is 56 feet and the length of ribbon B is 59 feet.

Alex777 [14]

The length of ribbon C is 37 feet.

<h3>What is the length of ribbon C?</h3>

The equation that can be used to determine the length of ribbon C is:

C = 34 + ( length of ribbon B - length of ribbon A)

C = 34 + (59 - 56)

C = 34 + 3

c = 37 feet

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
