Find the slope of the line on the graph.

Rasek [7]

The slope should be -1/2, because the line goes down 1 unit and then right 2 units.

Also it would be <u>y = -1/2x+1</u> in <u>y=mx+b</u>.

An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment

stealth61 [152]

Answer: First option is correct.

Step-by-step explanation:

Enrollment month Actual Predicted Residual

January 500 8 4

February 400 15 -1

March 550 15 -1

April 13 12 -1

May 16 17 -1

June 14 15 -1

Since we know that

Residual value = Actual value - Predicted value

Sum of residuals is given by

$4-1-1+1-1-1=1$

since we can see that sum of residual is more than 0.

So, it can't be a good fit .

Hence, No, the equation is not a good fit because the sum of the residuals is a large number.

Therefore, First option is correct.

A. Using a protractor, draw a triangle that has two angles of 40°. Label all angle measures on your drawing and include your dra

PtichkaEL [24]

Answer:

Step-by-step explanation:

By terms of angle based conclusion triangle can be Obtuse angled triangle and by considering the sides as all angles are different It will be Scalene Triangle.

Step-by-step explanation:

Given:

Two angles of 40 degree

To Find :

How many triangles are possible Construct the triangle with given condition and Describe it.

Solution:

For Construction ,

Consider Triangle ABC with

∠A+∠B=40

So for 1st possibility as ∠A=10 then ∠B=30

2nd possibility as ∠A=20 then ∠B=20

3rd Possibility as ∠A=30 then ∠B =10

And angle c will remain the same for all three possibility i.e

Sum of all angles in triangle is 180

so angle c=140 degrees.

Hence there 3 Possibilities by which triangles can be made

So both angle A and B are acute angle since they measure less than 90 degree.

And angle C is Obtuse angle always

So angles in triangles are 2 acute and one Obtuse angle.

So One angle is Obtuse then triangle is Obtuse angled triangle

So triangle ABC is Obtuse angled triangle.

we can say that all three side will be different as all angles are different measures

So Triangle ABC is scalene triangle.

hope this helps =)
