What mathematics concepts or principles did you apply to come up with the solution of each equation? explain how you applied the

AlexFokin [52]

You need to look at the question again, and notice the words "... did you ...".
From those words, it's clear that the question comes AFTER you have solved
several equations, and now, this question is asking you how you solved them.

The only way for YOU to answer this question is to solve the equations first.

And if you want someone ELSE to tell the math concepts and principles that
are used to solve them, then you have to show him what the equations are.

Assume that adult IQ scores on the Weschler IQ test are normally distributed with a mean of 100 points and a standard deviation

Elodia [21]

Hi there!

With a normal distribution, we can use the operation 'normalcdf' on a calculator to find the probability that a randomly selected adult has an IQ between 96 and 111.

Here is the format for using the operation:

<h2>normalcdf(LB, UB, μ, σ) </h2>

LB = Lower bound (96)

UB = Upper bound (111)

μ = Mean of normal distribution (100)

σ = Standard deviation of normal distribution (15)

Plug in the given values into the calculator and solve.

$normalcdf(96, 111, 100, 15) = \boxed{0.3735 }$

The equation in the given standard form is $(x+10)^2+(y+6)^2=5^2$

<h3>Equation of a circle</h3>

The standard equation of a circle is expressed as:

$(x-a)^2+(y-b)^2=r^2$

Given the equation $x^2 + y^2 + 20x + 12y + 111 =0$

Group the function to have:

$(x^2 +20x)+(y^2+ 12y) + 111 =0$

Complete the squares to have:

$(x^2 +20x)+(y^2+ 12y) + 111 =0\\(x^2+20x+10^2-10^2)+(y^2+12y+6^2-6^2)+111=0\\(x+10)^2+(y+6)^2 -100-36+111=0\\(x+10)^2+(y+6)^2-25=0\\(x+10)^2+(y+6)^2=25\\(x+10)^2+(y+6)^2=5^2$

Hence the equation in the given standard form is $(x+10)^2+(y+6)^2=5^2$
