What is the decibel level of the sound of a ticking clock with intensity 10−9 watts per square inch? Use a logarithmic model to

Response:

Detailed explanation:

There are seven rainbow colors: red, orange, yellow, green, blue, indigo, and violet, so 7 possible choices. When two events occur in sequence, multiply their probabilities. With replacement: P(violet)=1/7 and P(orange)=1/7, so P(violet then orange)=1/7 * 1/7 = 1/49. Without replacement: after picking violet, P(orange)=1/6, so P(violet then orange)=1/7 * 1/6 = 1/42.

Response

The first diagram displays angles 1 and 2 as vertical angles.

Clarification

In all four diagrams, the initial one illustrates the vertically opposite angles.

Angles 1 and 2 are classified as vertically opposite because they face each other.

These angles maintain equal measurement when two lines intersect, resulting in four angles where two pairs of vertically opposite angles are formed.

In contrast, all other figures depict angles 1 and 2 as adjacent angles.

Answer:

The correct selection is 1.

Step-by-step explanation:

The histogram indicates that

In the 5-10 age group, there are 7 students.

In the 11-13 age group, 5 students are represented.

In the 14-18 age category, 4 students are included.

This implies that the ages of 7 students fall within the 5-10 range, 5 students within the 11-13 range, and 4 students within the 14-18 range.

The total count in the dataset is

In options 3 and 4, the counts in the datasets are fewer than 16. Hence, options 3 and 4 are invalid.

Option 2 exclusively contains data within the 5-10 range, making it incorrect as well.

In option 1,

Class intervals      elements           frequency

5-10                    5,6,7,8,9,10,10           7

11-13                  11,11,12,12,13            5

14-18                    14,14,15,16              4

Based on the above table, we can determine that data set 1 is represented in the provided histogram.

Thus, the answer is option 1.
