Hello!

As we can see, our a value, which would be the coefficient of x, which determines our slope, is negative, meaning that this whole line is negative.

Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.

If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.

a camper has 6 storage compartments. each compartment can hold 3 sleeping bags. if there are 17 sleeping bags to be stired, how
liberstina [14]

Answer:

The camper will use all 6 storage compartments, with 2 sleeping bags in the one that is not completely filled.

Step-by-step explanation:

If 6 storage compartments can each hold 3 sleeping bags, 18 (6*3) sleeping bags in total will be able to be stored.

We only have 17, which is one bag less than 18, so we can think of it as having one compartment with one bag less than all the others (they have three). Therefore, there are 2 sleeping bags in that storage compartment.

We can also divide 17 by 3 to find how many compartments will be filled. The remainder is the number of bags in the one that is not completely full.

17/3 = 5 r2

But because the camper still needs to put those two sleeping bags in a compartment, they will use 6.

Is there an association between favorite core subject and favorite elective? If so, describe it.
Luda [366]

<u>Answer:</u>

<u>Yes</u>

Step-by-step explanation:

Take note that a favorite core subject represents subjects that are widely recognized as important to the student's line of study, they include subjects like Maths, English, Science, and Engineering.

While Elective subjects are optional subjects that are deemed less important than the core, but by choosing one's favorite elective subject shows that individual places a certain level of importance that is almost that of the core subject.

Ch. 6 Challenge
Tju [1.3M]
36= 12.5% because 25%+62.5%= 87.5%

So 100%-87.5%=12.5%

87.5%-12.5%= 75%

36+36=72=25%

72+72+72+72= 288 = 100%

So the total number of pages in the magazine is 288

Find the measure of each exterior angle of a regular decagon . Explain please .number 4
Svet_ta [14]
A decagon is a polygon that has 10 sides and 10 interior angles ("deca" comes from the greek "deka" which means 10; the part "gon" is from the greek "gonia" for "corner or angle". So "decagon" means "10 corners" or "10 angles")

A regular decagon has each exterior angle equal to 36 degrees. To find this, you would divide 360 over 10. The formula you use is
E = 360/n
E = 360/10
E = 36
Where n is the number of sides and E is the exterior angle measure. Keep in mind this formula only works for regular polygons. The polygons must have the same side length all around, and the angles must be congruent as well.

Arrange the steps in the correct order to solve the equation 3 (2^2t-5 )- 4=10
liberstina [14]
The equation to be solved is: 3 [ 2 ^ (2t - 5) ] - 4 = 10

The steps are:

1) transpose - 4=> 3 [ 2^ (2t - 5) ] = 10 + 4

2) Combine like terms => 3 [2^ (2t - 5) ] = 14

3) Divide both terms by 3 => 2^ (2t - 5) = 14 / 3

4) Take logarithms of both sides => (2t - 5) log (2) = log (14/3)

5) Divide both sides by log (2) =>

                log (14/3)
2t - 5 = -------------------
                 log (2)

6) transpose - 5+>

                log (14/3)
2t  = ------------------- + 5 = 2.22 + 5
                 log (2)

2t = 7.22

7) divide both sides by 2 => t = 7.22 / 2 = 3.61
