the area of a trapezoid is 152. the height is 16 and the length of one of the sides is 6. find the length of the second parallel

kari74 [83]

Formula for trapezoid
A=h*(b1+b2)/2,

b1 an db2 are the two lengths of the sides

152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13

A = 16*(6+13)/2=16*9.5=152

Answer:

The geometric mean of given data is approximately 2.6051

Step-by-step explanation:

We are given the following data in the question:

1, 2, 3, 4, 5.

We have to find the geometric mean.

Formula:

$(a_1\times a_2\times... \times a_n)^{\frac{1}{n}}$

Putting the values, we get,

$\text{Geometric mean} = (1\times 2\times 3\times 4 \times 5)^{\frac{1}{5}}\\=(120)^{\frac{1}{5}} \approx 2.6051$

Thus, the geometric mean of given data is approximately 2.6051
