How to construct 165 degress angle with compass and scale and show picture

1 answer:

8 0

To start with, draw a line say AB.
At point B, construct 60 degrees.
Bisect the angle to get 30 degrees.
Bisect the 30 degrees to get 15 degrees.
The angle opposite the 15 degrees is 165 degrees

The following list gives the number of public libraries in each of 14 cities.

Yuri [45]

Given:

The date set for the number of public libraries in each of 14 cities is:

4, 5, 4, 6, 5, 6, 5, 8, 5, 4, 6, 6, 7, 4

To find:

The modes of this data set.

Solution:

We know that, the mode of a data is the most frequent value of data set.

Arrange the given data in ascending order.

4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 7, 8

In the given data set,

Frequency of 4 = 4

Frequency of 5 = 4

Frequency of 6 = 4

Frequency of 7 = 1

Frequency of 8 = 1

Clearly, the data values 4, 5, 6 have the largest frequency, i.e., 4.

Therefore, the modes of the given data set are 4, 5, 6.

Write the equation of the line given the points (2,0) and (3.-1)

Juli2301 [7.4K]

Answer:

y = -1x + 2

Step-by-step explanation:

We need to find y = mx + b

Use the following equation

$\frac{y_2-y_1}{x_2-x_1}$

Plug in the values

$\frac{-1-0}{3-2}$ = $\frac{-1}{1} = -1$

We have found the slope(m) which is -1

We have to find y-int b

Plug in any given x,y into the slope formula

-1 = -1(3) + b

-1 = -3 + b

2 = b

At last the formula is

y = -1x + 2
