Answer:
34.5
Step-by-step explanation:
Given the data:
X : 18; 18; 21; 22; 25; 26; 27; 29; 30; 31; 31; 33; 36; 37; 37; 41; 42; 47; 52; 55; 57; 58; 62; 64; 67; 69; 71; 72; 73; 74; 76; 77.
The 37th Percentile :
37/100(n + 1)th term
n = sample size = 32
Therefore,
0.37(32 + 1)th term
0.37(33)th term = 12.21 th term
(12th + 13th) term ÷ 2
(33 + 36) / 2
69 / 2
34.5
The 37th percentile is 34.5
Given :
- Base = 20 cm and 14 cm.
- Height = 5 cm.
To find :
Solution :
We know,
![{\qquad \dashrightarrow{ \bf{Area_{(Trapezoid)}= \dfrac{1}{2 } \times (b_{1} + b_{2}) \times h} }}](https://tex.z-dn.net/?f=%7B%5Cqquad%20%5Cdashrightarrow%7B%20%5Cbf%7BArea_%7B%28Trapezoid%29%7D%3D%20%5Cdfrac%7B1%7D%7B2%20%7D%20%20%5Ctimes%20%28b_%7B1%7D%20%2B%20b_%7B2%7D%29%20%5Ctimes%20h%7D%20%7D%7D)
Now, Substituting the values :

Therefore,
- <u>The area of the trapezoid is 85 cm²</u> .
I am assuming the equation would be something like 65 3/5 = 24 1/3 + d
Answer:
a triangle with two equal sides
Step-by-step explanation:
Answer:
The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
Step-by-step explanation:
In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;
sum of interior angle = (n−2) × 180°
where
n = number of sides
The sum of the interior angle should be less than 7500 and greater than 7201.
sum of interior angle = (n−2) × 180°
less than 7500 and greater than 7201 = (43 - 2) × 180
less than 7500 and greater than 7201 = 41 × 180
less than 7500 and greater than 7201 = 7380
