Answers

Answer:

arc QS = 104°

Step-by-step explanation:

arc QTS = 2(128) = 256

arc QS = 360 - 256 = 104°

The measure of arc length QS is 104.

We have,

An inscribed angle is an angle whose vertex is on the circumference of a circle, and its sides are chords of the circle.

From the definition,

Inscribed angle = 1/2 x intercepted arc

Now,

128 = 1/2 x QTS

QTS = 256

Now,

QTS + QS = 360

256 + QS = 360

QS = 360 - 256

QS = 104

Thus,

The measure of QS is 104.

A scatter plot suggests a negative linear association. Which could be the scenario represented by this scatter plot?

Answers

Answer:

Step-by-step explanation:

The scenario represented by the given scatter plot is the score of one observation is high, we expect the score of the other observation to be low, and vice versa.

What is scatter plot?

A scatter plot is a set of points plotted on a horizontal and vertical axes. Scatter plots are important in statistics because they can show the extent of correlation, if any, between the values of observed quantities or phenomena called variables.

When the points on a scatterplot graph produce a upper-left-to-lower-right pattern, we say that there is a negative correlation between the two variables. This pattern means that when the score of one observation is high, we expect the score of the other observation to be low, and vice versa.

Hence, the scenario represented by the given scatter plot is the score of one observation is high, we expect the score of the other observation to be low, and vice versa.
