Answer:
Descriptive statistics <u>describe data from surveys and case studies,</u> while inferential statistics <u>determine if data can be generalized to other populations</u>.
Step-by-step explanation:
Let's look at the definition of each type of Statistics
Descriptive Statistics, as the name says, describes, properties or characteristics (that can be gathered through surveys and case studies), using mathematical methods for tendency and dispersion.
Inferential statistics, as the name states, infers, if samples from a larger data set have behaviors that can be then extrapolated to the larger group.
The angular size of Mars, as seen from the Earth, when it was closest to the Earth is 25 arcseconds.
<h3>What is angular size?</h3>
It should be noted that angular size is the object's apparent size as seen from an observer on Earth.
At its closest approach, the angular size of Mars is 25 arcseconds. This was known through the use of a telescope.

The square root of 71 is equal to 8.426149773176359...., which is between 8 and 9.
To check: square of 8 is 64, and of 9 is 81: 71 is between those two numbers, as it should be.
Answer: 2
Step-by-step explanation:
By the law of sines,
![\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \frac{\sin B}{14}=\frac{\sin 30^{\circ}}{8} \\ \\ \frac{\sin B}{14}=\frac{1}{16} \\ \\ \sin B=\frac{14}{16} \\ \\ B=\sin^{-1} \left(\frac{14}{16} \right), 180^{\circ}-\sin^{-1} \left(\frac{14}{16} \right) \\ \\ B \approx 61.04^{\circ}, 118.96^{\circ}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%20B%7D%7Bb%7D%3D%5Cfrac%7B%5Csin%20A%7D%7Ba%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7B%5Csin%20B%7D%7B14%7D%3D%5Cfrac%7B%5Csin%2030%5E%7B%5Ccirc%7D%7D%7B8%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7B%5Csin%20B%7D%7B14%7D%3D%5Cfrac%7B1%7D%7B16%7D%20%5C%5C%20%5C%5C%20%5Csin%20B%3D%5Cfrac%7B14%7D%7B16%7D%20%5C%5C%20%5C%5C%20B%3D%5Csin%5E%7B-1%7D%20%5Cleft%28%5Cfrac%7B14%7D%7B16%7D%20%5Cright%29%2C%20180%5E%7B%5Ccirc%7D-%5Csin%5E%7B-1%7D%20%5Cleft%28%5Cfrac%7B14%7D%7B16%7D%20%5Cright%29%20%5C%5C%20%5C%5C%20B%20%5Capprox%2061.04%5E%7B%5Ccirc%7D%2C%20118.96%5E%7B%5Ccirc%7D)
Since either of these values for B will form a triangle (as A+B will be less than 180 degrees), 2 triangles can be formed with these measurements.
