Cerrena [4.2K]

Modern numbers are the ten numerical digits used in constructing other numbers.

<h3>What are modern numbers?</h3>

Modern numbers are also called Arabic numerals. They are the ten numerical digits:

0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Uses of modern numbers;

  • They are used as symbols to write decimal numbers.
  • They are used in writing numbers in other systems like the octal, and for writing identifiers such as computer symbols, trademarks, or license plates.
  • They are used in constructing other numbers.

Hence, modern numbers are the ten numerical digits used in constructing other numbers.

What is an equation of the line that is parallel to y=9−5x and passes through (0, 8) ?
TEA [102]

Answer:

y = -5x Y8  

Step-by-step explanation:

Parallel lines have the same slope.

Your function is

y = 9 − 5x = -5x+ 9

slope = -5

The parallel line

The line must have slope = -5 and include (0, 8), so

8 = -5×(0) + b

8 = 0 + b

b = 8

The equation for the parallel line is

y = -5x + 8

In the diagram below, the red line is the graph of y = 9 -5x.

The parallel blue line is the graph of y = -5x + 8.

Point A,located at (-11,-7) on the coordinate plane,is reflected over the x-axis to form point B.Then point B is reflected over
Alekssandra [29.7K]

Answer:

B (-11,7)

C (11,7)

Step-by-step explanation:

The coordinates of point A are (-11,-7).

If the point is reflected over the x-axis to form point B then, the x coordinate will remain the same and the y coordinate will change by sigh only.

So, coordinates of point B will be (-11,7)

Now, point B is reflected over the y-axis to form point C.

Hence, the y coordinate of point C will remain the same as point B and the x coordinate of point B will change by its sign only.

Therefore, the coordinates of point C will be (11,7). (Answer)

In a normal distribution, 95% of the data fall within how many standard deviations of the mean? O A. Three standard deviations B
Galina-37 [17]

Answer:

Two standard deviations

Step-by-step explanation:

The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;

one standard deviation lie within 68% of the mean

Two standard deviations lie within 95%

Three standard deviations lie within 99.7%

Hence, for the question given, 95% fall within 2 standard deviations of the mean
