Answer:

The perimeter of the square is 31.96\ m

Step-by-step explanation:

we know that

The perimeter of a square is equal to

P=4b

where

b is the length side of the square

Step 1

Find the length side of the square

The diagonal of the square is equal to

Applying the Pythagoras Theorem

d^{2} =b^{2}+b^{2}\\d^{2}=2b^{2}\\d=b \sqrt{2}

In this problem we have

d=11.3\ m

d=b\sqrt{2} ------> solve for b

b=d/\sqrt{2}

substitute the value of d

b=11.3/\sqrt{2}\ m

Step 2

Find the perimeter of the square

P=4b

Substitute the value of b

P=4(11.3/\sqrt{2})=31.96\ m

The length of each side can be found using pythagoras theorem:-

11.3^2 = 2x^2     where x = length od each side
x = sqrt( [11.3^2  / 2)
x =  7.99 meters

Which of the following equations correctly represents the law of sines?
aev [14]
The Law of Sines may be written as
b/sin(B) = c/sin(C)

Multiply each side by sin(B).
b = (c*sin(B))/sin(C)

The correct answer is C.

Answer: C. (c*sin B)/sin C

Many residents of suburban neighborhoods own more than one car but consider one of their cars to be the main family vehicle. The
horrorfan [7]

Answer:

95.4% of family vehicles is between 1 and 3 years old.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 2

Standard Deviation, σ = 6 months = 0.5 year

We are given that the distribution of age of cars is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(family vehicles is between 1 and 3 years old)

P(1 \leq x \leq 3)\\\\ = P(\displaystyle\frac{1 - 2}{0.5} \leq z \leq \displaystyle\frac{3-2}{0.5}) = P(-2 \leq z \leq 2)\\\\= P(z \leq 2) - P(z < -2)\\= 0.977 -0.023 = 0.954= 95.4\%

P(1 \leq x \leq 3) = 95.4%

95.4% of family vehicles is between 1 and 3 years old.
