Answer:

$b = 0.0138$

Step-by-step explanation:

Given

Regression Equation:

$DD=2.69+0.0138D$

Required

Determine the slope of the regression line

The equation of regression is of the form

$Y = a + bX$

Where b represents the slope;

Compare $Y = a + bX$ to the given equation

$DD=2.69+0.0138D$

We have that:

$Y = DD$

$a = 2.69$

$b = 0.0138$

$X = D$

Hence; the slope is:

$b = 0.0138$

Bruno and Willie need a total of $50,000 to start an accounting business. Bruno has spent a lot of time getting the business set

Gnom [1K]

The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.

Let amount contributed by Willie be x

Let amount contributed by Bruno be y

Since Willie agreed to contribute $12,000 more than Bruno;

Therefore;

x - y = 12000....…....... equation (1)

x + y = 50,000...…....... equation (2)

By solving the system of equations simultaneously;

2x = 62000

x = 31000

and y = 50,000 - 31000

y = 19,000

In essence; The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.

Answer:

Option D that is y=-2(x+1) is the correct choice.

Explanation:

Given equation:

$y=2x-2$

We have to find another equation which has only one solution.

Standard form of equation:

$1.a_1x+b_1y+c_1=0$

$2.a_2x+b_2y+c_2=0$

Condition for one solution.

$\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$

We have to arrange other equation in the form of $ax+by+c=0$

Mark all the options as a,b,c and d.

$a.\ 2x+1-y=0$

$b.\ 2x-2-y=0$

$c.\ 2x-4-y=0$

$d.-2x-2-y=0$

Now from the above options we can see that option $a,b\ and\ c$ are not providing the desired result.

$\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$ can be obtained from the last option.

$\frac{a_1}{a_2} \neq \frac{b_1}{b_2} ,\frac{2}{-2} \neq \frac{-1}{-1} ,-1\neq 1$

Option D that is $y=-2(x+1)$ is the equation from where we can obtained only one solution.
