Answer: Third option is correct.

Step-by-step explanation:

Statistical questions are those in which we get more than one numerical answer.

According to options,

In option 'A' how many theatres are there in my city, we get only one numerical value instead of collection of data.

In option 'B' how many students like classic movies in my class , in which we get only one numerical value.

In option 'C' how many movies do the students in my class watch in a month.

In this option we would get a collection of data i.e. more than one numerical value.

Because not every student watch same number of movies in a month.

In option 'D' again we get only one numerical value.

Hence, Third option is correct.

Answer:

The correct answer is:

0.01$ (c)

Step-by-step explanation:

Standard deviation is a measure of how spread out numbers are from the mean value. The formula for standard deviation is given by:

$s = \sqrt{\frac{\sum(x - \bar x)}{n} } \\where:\\x = sample\ \\\bar x\ = mean\\n\ = number\ of\ samples\$

Variance is a measure of the squared differences from the mean.

Variance is simply the square of the standard deviation. It is mathematically shown as:

$s^2 = \frac{\sum(x - \bar x)}{n} }$

Now in our example,

Stabnard deviation = $0.10

Variance = (standard deviation)²

Variance = (0.10)²

Variance = $0.01

Answer:

B) False

Step-by-step explanation:

Triangles are similar when their angles are the same measures. Because the angles sum to 180°, we only need to show that 2 angles of one triangle are equal to 2 angles of the other triangle.

All three of the angles of the first triangle are given: 20°, 40°, 120°.

One of the angles of the second triangle matches: 40°; but the other angle (80°) doesn't match either of 20° or 120°.

The angles aren't the same, so the triangles are not similar.

If we want to go to the trouble, we can figure the third angle of the second triangle. It is 180° -40° -80° = 60°.

Then the angles in the two triangles, listed smallest to largest, are ...

20°, 40°, 120°

40°, 60°, 80°

It is clear the angles of these triangles are not the same.
