Answer:7picm Circumference = pi x d Diameter = 7 C = pi x 7 C = 7pi cm.

Step-by-step explanation:

The circumference of the circle with diameter 2 cm is 6.28 cm.

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Given that a circle has a diameter of 2 cm we need to find its circumference,

The circumference of a circle is given by, π × diameter

Therefore, the circumference of the circle with diameter 2 cm =

= π × diameter

= π × 2

= 3.14 × 2

= 6.28 cm

Hence, the circumference of the circle with diameter 2 cm is 6.28 cm

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 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.

Answer:

(rectangular prism) Opposite sides are equal;

Area of bottom base:-

11 x 15 = 165

Above base, (165 x 2) = 330

Area of front:-

15 x 32 = 480

Area of back, (480 x 2) = 960

Area of left side:-

11 x 32 = 352

Area of right side, (352 x 2 ) = 704

Add the sums of all the areas;

330 + 960 + 704 = 1,994 square cm
