Answer 1

Answer:

Answer:

K=13

Step-by-step explanation:

So first, we subtract 13 with 3/4 (That comes from 4 3/4) and we get 12 1/4.

And then, we subtract 12 1/4 with 4, and we get 8 1/4

Have I made your day?

What are the coordinates of point P?

Answers

On this graph, coordinate P lies 2 units to the left of the center. The side-to-side movement of a point on a coordinate plane is called movement on the x-axis, and since it is 2 units to the left of the center, it is called -2. All units to the left of the zero point (middle of the graph) is counted in negative numbers.
Coordinate P also lies 4 units down from the center. Movement up and down the graph is called movement on the y-axis, and since it is 4 units below the center, it is called -4. All units below 0 on the y-axis are counted in negative numbers.
To assemble our coordinates, we just have to remember the format for coordinates on a plane, which is (x, y). The value of the point's position on the x-axis always comes first, followed by its position on the y-axis. In this case, the finished coordinate would be (-2, -4).
Hope that helped! =)

5. What is the area of the figure to the nearest square centimeter? It is composed of a symmetric hexagonand a semicircle 4 cm6 cm3 cm4 cmc 100 cmA 50 cm2D 129 cmB 86 cm

Answers

Area of the given figure is equal to $86\ cm^(2)$ ( nearest square centimeter).

What is area?

" Area is defined as the total space occupied by any two-dimensional object enclosed in it."

Formula used

Area of rectangle = length × width

Area of triangle $= (1)/(2) * base * height$

Area of semi-circle $= (1)/(2) * (\pi r^(2) )$

$r=$ radius of the circle

According to the question,

Given figure is composed of :

two congruent rectangles, four congruent triangles, one semi-circle

Given dimensions,

Length of a rectangle $= 6cm$

Width of a rectangle $= 4cm$

Height of a triangle $= 4cm$

Base of a triangle $= 3cm$

Radius of the semicircle $= (6)/(2)$

$=3cm$

Substitute the value in the formula to get the required area,

Area of a rectangle $= 6 * 4$

$= 24 cm^(2)$

Area of a triangle $= (1)/(2) * 3* 4$

$= 6 cm^(2)$

Area of a semicircle $= (1)/(2) * \pi * 3^(2)$

$=4.5 * 3.14\n\n= 14.13 cm^(2)$

Substitute the value to get the required area,

Area of the given composed figure $= 2* 24 + 4* 6 + 14.13$

$= 48 + 24 + 14.13\n\n= 86.13 \ cm^(2)$

≈ $86 cm^(2)$ (nearest square centimeter)

Hence, Option(B) is the correct answer.

A music website tracked the number of new users per day over 1 week. The number of new users for each day of the 7 days was 38, 43, 45, 50, 51, 56, 67.a. What is the MAD of the number of new users per day? Round to the nearest tenth.

b. What does the value of the MAD represent? Explain

Answers

Part a)

MAD = median of absolute deviations

MAD = median of the set formed by : |each value - Median|

Then, first you have to find the median of the original set

The original set is (38, 43, 45, 50, 51, 56, 67)

The median is the value of the middle (when the set is sorte). This is 50.

Now calculate the absolute deviation of each data from the median of the data.

1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17

Now arrange the asolute deviations in order

(0, 1, 5, 6, 7, 12, 17)

The median is the value of the middle: 6.

Then the MAD is 6.

Part b) MAD represents the median of the of the absolute deviations from the median of the data.
