The goal is not only to model the vector with 2 - D and to determine its important parameters, but also to examine the impact in the implementation. That is, Ogden's material parameters, element type, element size, and loading type.

Nancy found that x=1 is one solution to the quadratic equation (x 2)2=a. what is the value of a? -9 -3 3 9
AlladinOne [14]

The value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

<h3>What is the solution of equation?</h3>

The solution of the quadratic equation is the solution of the variable of the equation, for which the equation satisfies.

Nancy found that x=1 is one solution to the quadratic equation. The quadratic equation is,

(x +2)^2=a

For this equation, one solution is <em>x</em>=1. Put this value in the above equation to get the value of <em>a,</em>

(1 +2)^2=a\\(3)^2=a\\9=a\\a=9

Thus, the value of the <em>a, </em>in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

Angle BOC = 120

PROOF

Angle A + Angle B + Angle C = 180

So, Angle B + Angle C = 120 (Angle A = 60)

Now 1/2 (Angle B + Angle C) = 60

1/2 Angle B + 1/2 Angle C = 60..............i

In triangle BOC

1/2 Angle B + 1/2 Angle C + Angle BOC =180

(BO and CO are angle bisectors)

Or 60 + Angle BOC = 180 (using i)

OR ANGLE BOC = 120

A set of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars.
blagie [28]

We have been given that a of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars.  A leather sofa has a price of 2410 dollars. We are asked to find the proportion of sofa prices that are higher than the price of the leather sofa.

First of all, we will find the z-score corresponding to sample score 2410.

z=\frac{x-\mu}{\sigma}

z=\frac{2410-2500}{200}

z=\frac{-90}{200}

z=-0.45

Now we need to find area under normal curve that is greater than z-score of -0.45 that is P(z>-0.45).

Using formula P(z>a)=1-P(z, we will get:

P(z>-0.45)=1-P(z

Now we will find area under curve using normal distribution table.

P(z>-0.45)=1-0.32636

P(z>-0.45)=0.67364

Upon rounding to 4 decimal places, we will get:

P(z>-0.45)\approx 0.6736

Therefore, approximately 0.6736 of sofa prices are higher than the price of the leather sofa.
