Answer:

Step-by-step explanation:

This might be familiar to you if you know about the pythagorean relationship in right triangle, aka pythagoras's theorem.

It states that, in a right triangle, the sum of the squares of the 2 shorter sides equals the square of the longest side, aka the hypotenuse.

Note that the triangle in this case is a right angled triangle, and all the surrounding shapes are squares.

So by the pythagorean relationship we have,

2^2 + 4^2 = c^2

4 + 16 = c^2

20 = c^2

c =  sq root 20 = 2 * sq root 5

Hope it helps and if it does, plzzz mark me brainliest ;-)

How do I write an equation for each parabolas?
fredd [130]

Step-by-step explanation:

  1. In the first parabola it opens on the left and the equation of parabola can be expressed as,

              in vertical component <u>(y)² = (-) a (x-h)² + k</u>

cause  the parabola is horizontal and it opens on the left.

          2. In the second parabola the vertex opens on the right and hence the      equation cane be given as,

    in vertical component <u>(y)² = a (x-h)² + k</u>

cause the parabola is horizontal and opens on the right.

       3. the third equation is given as,

        in horizontal component<u> (x²) =</u> <u> (-) a (x-h)² + k</u>

since the parabola is vertical and opens down.

        4. the fourth equation is given as,

        in the horizontal component  <u>(x)² = a (x-h)² + k</u>

since the parabola is vertical and opens up.

A tobacco company claims that the amount of nicotine in its cigarettes is a randomvariable with mean 2.2 mg and standard deviati
Genrish500 [490]

Answer:

0.0000

Unusual

Step-by-step explanation:

Given that a tobacco company claims that the amount of nicotine in its cigarettes is a random variable with mean 2.2 mg and standard deviation .3 mg.

i.e. population parameters are

\mu =2.2 \\s = 0.3

The approximate probability that the sample meanwould have been as high or higher than 3.1

=P(X\geq 3.1)\\=P(Z\geq \frac{3.1-2.2}{\frac{0.3}{\sqrt{100} } } )\\=P(Z\geq 30)\\

=0.0000

miss Akunina [59]

the answer is y=3x-6

subtract 6x on both sides → -2y=-6x+12
