Graph the inequality in the coordinate plane:<br><br> x&lt;-3
tensa zangetsu [6.8K]

Answer:

Graph of the inequality x< -3 as shown below in the figure.

Step-by-step explanation:

Given the inequality: x < -3

Graph of this inequality as shown below in the figure.

All the points that are lie in the shaded area satisfy the equation x < -3 or

In other words, we can say that x can take any value less than -3 .

x ≠ -3 or any number that is greater than -3.

Since there is a strict inequality i.e x < -3 , the points that lie on the line x = -3 does not satisfy the equation.

Therefore, the dotted line is marked at x = -3

Answer:

(x+2\sqrt{3} )(x+\sqrt{3} )

Step-by-step explanation:

x^2 + 3\sqrt{3}x + 6\\=> x^2 + \sqrt{3}x + 2\sqrt{3}x +6\\=> x( x+\sqrt{3}) + 2\sqrt{3}(x+\sqrt{3} )\\  => (x+2\sqrt{3} )(x+\sqrt{3} )

Rashid [163]

A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.

Answer: The given z-score is false.

Explanation: We are given:

Mean, \mu=100,

Variance, \sigma^{2}=25

\therefore\sigma=\sqrt{\sigma^{2}}

                 =\sqrt{25}

                 =5

The z-score formula is given below:

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

        =\frac{110-100}{5}

        =\frac{10}{5}

        =2

Therefore, the z-score corresponding x=100 is 2

Therefore, the given z-score = 0.4 is false.
