Answer:

$A=782\ yd^2$

Step-by-step explanation:

The area of the figure is equal to the area of four right triangles

The area of one right triangle is equal to

$A=\frac{1}{2}(23)(17)$

$A=195.5\ yd^2$

Multiply by 4

$A=(4)195.5=782\ yd^2$

<em>Alternative Method</em>

The figure is a Rhombus

The area of the Rhombus is equal to

$A=\frac{1}{2}(D_1)(D_2)$

where

D1 and D2 are the diagonals of the rhombus

we have

$D_1=(23+23)=46\ yd\\D_2=(17+17)=34\ yd$

substitute

$A=\frac{1}{2}(46)(34)$

$A=782\ yd^2$

How would you calculate the area and perimeter of 3yd 6yd 5yd 10yds

spayn [35]

Okay, start with the smaller square, you know the side length is 3 and that the width is 5, multiply this together:
3 * 5 = 15

That's the smaller left side of this shape, now the bigger side, divide the 10 yards at the bottom by 2 to properly represent the other side then multiply this by the 6 over there.
5 * 6 = 30

Conclusion for Area: After adding the results the answer should be 45.

The perimeter is solely adding all the sides together. You have a 10, two 5's, one 6, and two 3's. Add this together:

10 + 5 + 5 + 6 + 3 + 3 = 32

Conclusion for Perimeter: So the perimeter would be 32.

I hope this helps in someway, have a great rest of your day! ^ ^

A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not all

Answer:

The following are the answer to this question:

Step-by-step explanation:

In the given question the numeric value is missing which is defined in the attached file please fine it.

Calculating the probability of the distribution for x:

$\to f(x) = 0.19\ for \ x=14\\\\\to f(x) = 0.29 \ for\ x=7\\\\\to f(x) = 0.38\ for \ x=1\\\\\to f(x)=0.14 \ for \ x=0\\$

The formula for calculating the mean value:

$\bold{ E(X)= x \times f(x)}$

$=14 \times 0.19+7 \times 0.29+1 \times 0.38+0\times 0.14\\\\=2.66 + 2.03+0.38+ 0\\\\=5.07$

$\bold{E(X^2) = x^2 \times f(x)}$

$=14^2 \times 0.19+7^2 \times 0.29+1^2 \times 0.38+0^2 \times 0.14 \\\\=196 \times 0.19+ 49 \times 0.29+1 \times 0.38+0 \times 0.14\\\\= 37.24+ 14.21+ 0.38+0 \\\\=51.83$
