Answer:

The equation of the line of reflection will be x = y.

Step-by-step explanation:

On a coordinate plane, triangle Δ ABC has points (6, 3.7), (5.4, 2), (1, 3). And triangle Δ A'B'C' has points (3.7, 6), (2, 5.4), (3, 1).

Now, Δ A'B'C' is the image triangle of Δ ABC and we have to find the equation of the line of reflection.

We know that after reflection of a point P(h,k) over the line x = y the image will be P'(k,h).

Same is happened in case of Δ ABC and Δ A'B'C'.

Therefore, the equation of the line of reflection will be x = y. (Answer)

Zigmanuir [339]

Answer:

a) The expected value of the mean of the 49 randomly selected students, M, is 7.06 digits

b)

The Standard error of the mean is 0.2328

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given sample size 'n' = 49

The Expected value of the mean of 49 randomly selected students

μₓ = μ =7.06 digits  

b)

<em>The Standard error of the mean determined by</em>

<em></em>S.E = \frac{S.D}{\sqrt{n} }<em></em>

Given sample size 'n' = 49

<em>The Standard deviation 'σ' = 1.63 digits</em>

<em>The Standard error </em>

S.E = \frac{S.D}{\sqrt{n} }

S.E = \frac{1.63}{\sqrt{49} } = 0.2328

<u><em>Final answer</em></u>:-

a) The expected value of the mean of the 49 randomly selected students, M, is 7.06 digits

b)<em> The Standard error of the mean is 0.2328</em>

navik [9.2K]
The plot: x meters wide and (x+30) meters long with an area of 15000 m^2. the equation you're searching for is:

x meters * (x+30) meters = 15000 m^2 or

x^2 + 30x m^2 = 15000 m^2 and

x^2 + 30x - 15000 = 0 <== that's the equation.

ans: x^2 + 30x - 15000 = 0
