Class intervals in a grouped frequency distribution are given as 4−11, 12−19, 20−27, 28−35, 36−43. Write the next two class intervals.
i) what is the each class interval?
ii) write the class boundaries of all classes?
iii) what are the class marks of each class?​

Answers

Answer 1

Answer:

{44-55}{52- 59 } are the last two interval s

Step-by-step explanation:

To get the class boundaries deduct 0.5 from the first number and add 0.5 to the second number = 4-0.5 = 3.5 = 11.5 + 0.5 = 11.5 = 3.5 -11.5 as in the fish class boundary .same for all other boundaries

So, when they say quantities that combine to make 0, that means you have to lose, and then gain the same amount back.

If you look at all the other choices, they either keep on gaining or they don't gain the same amount they lost

Think about it as breaking even.  You aren't actually gaining anything if you are gaining back the exact same amount you lost.

The length of a rectangle is 13 centimeters less than four times its width. Its area is 35 square
centimeters. Find the dimensions of the rectangle.
The width is
and the length is

Answers

Answer:

width 5

length 7

Step-by-step explanation:

W * L = 35

L = 4 * W - 13

W * (4W-13) = 35

4 W^2 - 13 W - 35 = 0

delta = 169 + 4*4*35 = 729 = 27^2

W = (13 + 27) / 8 = 5 (its the only solution since 13 - 27 is less than 0 which makes no sense)

L = 4 * 5 - 13 = 7

The length and width of the rectangle are 7 cm and 5 cm respectively.

What is a rectangle?

A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel.

Given that, the length of a rectangle is 13 cm less than four times its width. Its area is 35 cm².

We know that, the area of a rectangle = length × width

Let the width of the given rectangle be w,

According to question,

length = 4w - 13

Therefore,

(4w - 13) × w = 35

4w² - 13w = 35

4w² - 13w - 35 = 0

Factorizing, we get,

w = 5 and w = -7/4

Therefore, width = 5

Length = 20 - 13

Length = 7

Hence, the length and width of the rectangle are 7 cm and 5 cm respectively.

The area of a rectangle is 36x^2 — 100y^2. Determine the length and the width of the rectangle.

Answers

Answer:

the length is represented by (6x + 10y) and the width by (6x - 10y)

Step-by-step explanation:

36x^2 - 100y^2 is the difference of two squares, so we need only factor this expression to obtain the length and width.

Recall that a similar difference, a^2 - b^2, comes out to (a - b)(a + b).

Thus, (36x)^2 = (100y)^2 = (6x - 10y)(6x + 10y).

Let's assume that the greater measurement, the length, is represented by (6x + 10y) and the width by (6x - 10y)

What is a line segment?

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Lines AB and XY best describe the perpendicular segments. AS they are cutting each other at 90 degrees.

The product of two consecutive odd integers is 63. If x is the smallest of the integers, write an equation in terms of x that describes the situation, and then find all such pairs of integers.

The negative set of integers is _________________

Answers

Answer:

x(x+2) = 637, 9-9, -7

Step-by-step explanation:

If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...

  x(x +2) = 63

__

The equation can be rewritten as ...

  (x +1)² = 64

  x = -1 ±√64 = -1 ±8

The positive solution is x=7, so the positive set of integers is {7, 9}.

The negative solution is x=-9, so the negative set of integers is {-9, -7}.
