Answer:
Total teachers = 150
Step-by-step explanation:
Let total teachers = x
12% of x = 18
[tex]\dfrac{12}{100}*x = 18\\\\\\x= 18*\dfrac{100}{12}=18*\dfrac{25}{3}\\\\\\x = 6*25\\\\x = 150[/tex]
_________
[tex]\:[/tex]
12%.x = 18
x = 18 × 100/12
x = 1.800/12
x = 150

A student has to take two quizzes tomorrow. He has only enough time to study for one of them. The history quiz has 5 true or false questions. The science quiz has 3 multiple choice questions. The student calculates the probability that he will get all the questions correct by guessing. The student will study for the quiz on which he is likely to do worse by guessing. Which quiz should he study for?
A. History, because he must get more questions correct.
B. Science, because the probability of getting all the questions correct is 0.016, which is lower than for history (0.031).
C. History, because the probability of getting all questions correct is 0.031, which is lower than for science (0.75).
D. Science, because the probability of getting all questions correct is 0.075, which is lower than for history (0.25).
Answer: option B
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
Based on the probabilities of passing, the quiz the student should study for is B. Science, because the probability of getting all the questions correct is 0.016, which is lower than for history (0.031).
Why should the student study science?If the student does not study science, they will most likely fail because the probability that they get all questions correct without studying is quite low.
If he must, the student can give up history because he still has a higher chance of passing it without studying.

3. Consider the iterative rules you wrote in Problem 2. (a) Explain why the rules are functions. (b) Your friend says that because the rules are functions, they can be graphed and must have y-intercepts. How would you respond to your friend’s comment? (c) Your friend uses your rules to determine the outputs when the inputs are 18.5. Explain why her outputs are meaningless in this situation. What would you tell her about the inputs she can use? Answer:
The inputs which are required mention below in descriptive.
What is Function?The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.
(a) The rules are functions because each input has only one output. You can test this out, it's true.
(b) So we did have to find the "y-intercept" earlier. But you have to look at the domain. There won't be any amount paid on Week 0, payment starts at Week 1. So you would have to respond that yes, they can be graphed, but there's no y-intercept; the graph starts at week 1. Additionally, there are only data points at the integer values of x. Look at part c.
(c) The outputs are meaningless because you're counting the time by weeks. There won't be any amount paid in the middle of the week, so she can only use integer inputs.

13 = 1/6y +2x plz help
Answer:
in standard form - y+12x=78
in slope intercept form - y=-12x+78
Step-by-step explanation:
standard form
13=1/6y+2x
multiply both sides by 6
78=y+12x
y+12x=78
slope intercept
13=1/6y+2x
subtract 1/6y from both sides
13-1/6y=2x
subtract 13 from both sides
-1/6y=2x-13
change the signs on both sides of the equation
1/6y=-2x+13
divide both sides by 1/6
y=-12x+78

Answer:
-1/2 would be your answer :)
Answer:
The answer is 2
Step-by-step explanation:
the answer would be 2 because the slope moved from (-2,0), to (0, 2). So it moved 2 spaces/grid places up.

Answer:
Refer to the graph. This might help you
Answer:
1/3
Step-by-step explanation:
y=mx+b
m is the slope
b is the y intercept
y=1/3x+4
1/3 = slope
4 = y intercept

Solve the system of equations by elimination:4p + 4q = 44p - 4q = 28
Answer:
p =9
q =2
Step-by-step explanation:
4p + 4q = 44 -----------(I)
4p - 4q = 28 -------------(II)
Add the equations and thus q will be eliminated and we can find the value of p.
(I) 4p + 4q = 44
(II) 4p -4q = 28 {Now add}
8p = 72
p = 72/8
p= 9
Plugin p = 9 in equation (I)
4*9 + 4q =44
36 + 4q = 44
4q = 44 - 36
4q = 8
q = 8/4
q = 2
