Answer:

9+7=16

Step-by-step explanation:

The probability that the employee is idle in the shopping mall based on the information given will be 0.33.

From the information given, it is believed that people will arrive at the desk at a rate of 20 per hour and that it takes an average of 2 minutes to answer a question.

Therefore, the probability that the employee is idle will be:

= 1 - (20/30)

= 1 - 0.67

= 0.33

Therefore, probability that the employee is idle is 0.33.

Hello.

Let's solve the absolute value inequality.

In order to do that, let's imagine that |3x-4| is positive.

Since the absolute value of |3x-4| is 3x-4, we write 3x-4 and solve:

[tex]\mathrm{3x-4\geq 8}[/tex]

Now, move -4 to the right, using the opposite operation:

[tex]\mathrm{3x\geq 8+4}[/tex]

Add:

[tex]\mathrm{3x\geq 12}[/tex]

Divide both sides by 3:

[tex]\mathrm{x\geq 4}[/tex]

However, this is only 1 solution.

Let's imagine that |3x-4| is a negative number.

So, the inequality looks like so:

[tex]\mathrm{-3x+4\geq 8}[/tex]

Move 4 to the right:

[tex]\mathrm{-3x\geq 8-4}[/tex]

[tex]\mathrm{-3x\geq 4}[/tex]

Divide both sides by -3:

[tex]\mathrm{x\leq \displaystyle-\frac{4}{3} }[/tex]

Therefore, the solutions are

[tex]\mathrm{x\geq 4}\\\mathrm{x\leq \displaystyle-\frac{4}{3} }[/tex]

[tex]\bigstar[/tex] Note:

If we divide both sides of an inequality by a negative number, we flip the inequality sign.

I hope this helps you.

Have a nice day.

Step-by-step explanation:

First triangle:

1. Find out the height

   [tex]h^{2} +8^{2} =17^{2}[/tex]

   [tex]h^2+64=289[/tex]

         -64     -64

Step-by-step explanation:

1. The y-intercept is the value for y when x = 0.

When x = 0, y equals 7.

Represented as:

(0, 7)

2. How to find the Slope?

Find 2 points on the graph then use the slope formula.

[tex] \frac{y2}{x2} - \frac{y1}{x1} = m[/tex]

m = slope

2 points:

(0, 7)

(2, 3)

Substitute the points into the formula:

[tex] \frac{3}{2} - \frac{7}{0} = m[/tex]

Subtract:

[tex] \frac{ - 4}{2} = m[/tex]

[tex] \frac{ - 4}{2} = m[/tex]Simplify:

[tex] \frac{ - 4 \div 2}{2 \div 2} = - \frac{2}{1} [/tex]

The slope is -2.

Forming an equation:

Use the slope-intercept format.

[tex]y = mx + b[/tex]

m = slope

b = y-intercept

Substitute 7 for b, and -2 for m.

[tex]y = - 2x + 7[/tex]

The length of the segment AC is 4√3, so the correct option is E.

In the image, you can see a right triangle.

We do know that AB = 8 units, and BC is equal to the radius of the circle.

We also know that the area of the circle is 16pi, and the area of a circle of radius R is:

A = pi*R^2

Replacing our area, we get:

16pi = pi*R^2

16 = R^2

√16 = R = 4.

So the radius of the circle is 4, which means that BC = 4.

Now we can use the Pythagorean theorem, that says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, this can be written as:

AB^2 = BC^2 + AC^2

8^2 = 4^2 + AC^2

64 - 16 = AC^2

√48 = AC

√(3*16) = AC

4√3 = AC

So the correct option is E.
