There is a mode formula, that is Mode = l + [(f₁-f₀)/(2f₁-f₀-f₂)] * h
Where,
l = lower limit of the modal class
h = size of the class interval
f₁ = frequency of the modal class
f₀ = frequency of the class preceding the modal class
f₂ = frequency of the class succeeding the modal class
What is mode?The value that consistently appears in a given set is the mode. The mode or modal value in a data set is sometimes referred to as the value or number that occurs most frequently in the data set. In addition to mean and median, it is one of the three measures of central tendency.
A mode is described as the value in a group of values that occurs more frequently. The value that appears the most frequently is this one.
To find the mode we use the formula Mode = l + [(f₁-f₀)/(2f₁-f₀-f₂)] * h
Where,
l = lower limit of the modal class
h = size of the class interval
f₁ = frequency of the modal class
f₀ = frequency of the class preceding the modal class
f₂ = frequency of the class succeeding the modal class

Answer:
1 is 105°
2 is 75°
Step-by-step explanation:
75° and angle 2 are corresponding angles(equal)
angles on straight line sum up to 180°
let x be angle 1
x+ 75= 180
x =180-75
x= 105°
Answer:
1. is 105
2. 75 degrees

What value of x makes the equation true?
3 - 14x = 17
A-1
B-1
C-28
D-2
Answer:
3 -14x =17
-14x = 17 - 3
-14x = 14
x = 14/-14 = 1/-1 = -1
∴ answer = -1

Step-by-step explanation:
Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?
Answer:
The number of paving stones she needs is 540 paving stone
Step-by-step explanation:
The given dimensions of Pisces' inground pool = 10 m by 5 m
The thickness of the border surrounding the pool = 1 1/2
The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m
The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m
The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m
The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool
∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²
The total area of the paving stone = 54 m²
The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone
The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)
∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

The length of three sides of a triangle are 3x+1/2 ,2x+1/4 , and x +1/2 .the perimeter of the triangle is
Answer:
Step-by-step explanation:
Just add the three sides P = side1 + side2 + side3
Don't let the 'x' terms confuse you, they are just numbers times 'x'
P = 3x+1/2 + 2x+1/4 + x+1/2
= 6x + 5/4
P = 6x + 1&1/4

Solve the quadratic equation by using either numeric or graphic approach x^2 + 2x - 3 = 0
Answer:
d
Step-by-step explanation:
[tex]x 1= \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} \\ x2 = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} \\ x1 = \frac{ - 2 + \sqrt{ {2}^{2} - 4\times 1 \times ( - 3)} }{2} = 1 \\ x2 = \frac{ - 2 - \sqrt{ {2}^{2} - 4 \times 1 \times ( - 3)} }{2} = - 3[/tex]
Answer:
d
Step-by-step explanation:
Solving by factorising
Given
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
