An employee works as a teacher at an online school making $38,900 per year. However, the school is hiring a principal at a salary of $59,500 per year.
The employee went back to school to become a principal.
How much more money could the employee make working as a principal instead of a teacher over 5 years?
Enter your answer in the box
Answer:
$103,000
Step-by-step explanation:
teacher : 38,900 x 5 = 194,500
principal : 59,500 x 5 = 297,500
$297,500 - $194,500 = $103,000 more

new shopping mall is considering setting up an information desk manned by one employee. Based upon information obtained from similar information desks, it is believed that people will arrive at the desk at a rate of 20 per hour. It takes an average of 2 minutes to answer a question. It is assumed that the arrivals follow a Poisson distribution and answer times are exponentially distributed.
a Find the probability that the employee is idle.
The probability that the employee is idle in the shopping mall based on the information given will be 0.33.
How to calculate probability?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.

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

The sum of two numbers is 16. One number is 2 less than the other. Find the numbers
Answer:
9+7=16
Step-by-step explanation:
1. what is the y-intercept of this line?
2. what is the slope of this line?
3. what is the equation for this line?
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]

Solve the follow inequality. ∣3x−4∣≥8
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: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.
What is a circle?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
