How could the relationship of the data be classified?

Mathematics
1 answer:
Korvikt [17]3 years ago
3 0

Answer:

That would be a fairly weak positive correlation.

Step-by-step explanation:

If you start in the origin and go up, the correlation is positive.

This would be fairly weak because the points are pretty scattered. If it were strong, you could almost draw the line of best fit by yourself. Here you can't.

How to evaluate an algebraic expression?
irinina [24]

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question.

Hope this helped                                     BTW can I have brainliest that would help me

In the context of a correlational study, what does the positive or negative sign of a correlation coefficient indicate?
Artyom0805 [142]

Answer:

Direct or inverse relation between two variables

Step-by-step explanation:

Now, we first have to understand that what is correlation study. In a correlational study, we try to find the relation between two variables. For example, mass and weight of a substance. If mass increases the weight will increase as well. it represent that both have strong positive correlation. Now the positive sign indicates that the correlation is directly proportional. Means if one variable increases, other will follow. Whereas, negative sign shows that two variables are inversely proportional, means, if one increases, other will decrease. For example any demand and supply system in economics. When supply is short, demand will rise, but if there is enough supply, demand will fall down accordingly.

Also notify that the coefficient is actually indicates the strength of relation between two variables. For example, if you pour water in container it will increase the weight of container, so it is directly proportional, now if you start to add honey, it will increase the weight of container more rapidly because honey has more density. So, coefficient of correlation for quantity of honey and weight of container is stronger than for quantity of water and weight of container.

CAN ANYONE HELP PIZZ FAST
Likurg_2 [28]

The figure/drawing isn't needed to answer this question.

The question tells us ABCD ~ WXYZ, which means trapezoid ABCD is similar to WXYZ.

Point A corresponds to point W, B corresponds with X, C corresponds with Y, and D corresponds with Z (first, second, third, and last letters correspond with each other according to the similarity statement).

Now let's check each answer choice and see which applies to these similar trapezoids:

  • Since point B corresponds with point X and the trapezoids are similar, they must be congruent angles. Thus, the first choice is correct.
  • Point Y does not correspond with point A. Thus, it is possible the angles are not congruent. The second choice is incorrect.
  • Point A corresponds with W and B corresponds with X. Thus, line segment AB will be similar to line segment WX. However, they are not equal. Thus, the third choice is incorrect.
  • There's an equal sign in this choice, too, just like the last, and the two segments are corresponding line segments. Thus, the fourth choice is incorrect.
  • This looks like the third choice, but with a similarity symbol instead of an equal sign. Now, the statement is true and the fifth choice is correct.
  • This looks like the fourth choice but with a similarity instead of an equal sign. Now, the statement is true and the sixth choice is correct.

Let me know if you need any clarifications, thanks!

12. Find the measure of each interior angle of triangle QRT.
Veseljchak [2.6K]

Answer:

\angle QRT=125.6\°

\angle RTQ=6.4\°

\angle TQR=48\°

Step-by-step explanation:

It is important to remember that, by definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this case we can idenfity that the angle 17x is an exterior angle of the triangle QRT. Then:

17x=\angle RTQ+\angle TQR

Where:

\angle RTQ=2x\\\\\angle TQR=48\°

Substituting values and solving for "x", we get:

17x=2x+48\\\\17x-2x=48\\\\15x=48\\\\x=3.2

Then:

17x=17(3.2)=54.4\°\\\\\\\angle RTQ=2(3.2)=6.4\°

The sum of the interior angles of a triangle is 180°, therefore:

\angle QRT+\angle RTQ+\angle TQR=180

Solving for \angle QRT, we get:

\angle QRT=180-48-6.4=125.6\°
