Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles )

∠ ABC = 87°

The least square regression equation for the information provided is y = 9.72x - 40.776

The general equation of a regression model can be expressed thus:

y = bx + c

Slope, b = r(Sy/Sx)

Calculating slope, b :

b = 0.81(177.6 / 14.8) = 9.72

Plugging the values of b, y and x into the equation in other to calculate c :

696 = 9.72(75.8) + c

696 = 736.776 + c

c = 696 - 736.776

c = - 40.776

Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

Which number line correctly shows 1.5 + 2.5?

GrogVix [38]

Answer:

We conclude that the first line number represents 1.5 + 2.5.

Step-by-step explanation:

Given the expression

$1.5 + 2.5$

It means the first segment must represent 1.5 units starting from 0.

Since we have to add 2.5 to 1.5, so the next segment must represent 2.5 units, starting from 1.5

Combining them would make

$1.5 + 2.5=4$

Now, if we observe the first number line,

The first arrow represents the 1.5 units starting from 0.

The second arrow represents the 2.5 units starting from 1.5.

The combined units of both arrows represent the length of 4 units. i.e. 1.5 + 2.5 = 4

Thus, we conclude that the first line number represents 1.5 + 2.5.

The correct line number is also attached below.
