Answer:
There were 60 teachers.
Step-by-step explanation:
☆We can use proportion to solve this!
[tex] \frac{3 \: teachers}{125 \: pupils} = \frac{x}{2500 \: pupils} \\ \\ \frac{125x}{125} = \frac{7500}{125} \\ \\ x = 60[/tex]
find the additive inverse of-9x+3
Answer:
9x − 3
Step-by-step explanation:
−9x + 3 = −1(−9x + 3) Multiply the expression by −1.
−1(−9x) + −1(3) Distributive Property
9x − 3 Simplify.
The additive inverse of the given expression is 9x-3.
The given expression is -9x+3.
What is additive inverse?The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.
The additive inverse of the expression is -(expression).
Now, -(-9x+3)
= 9x-3
Therefore, the additive inverse of the given expression is 9x-3.

The manager of a symphony in a large city wants to investigate music preferences for adults and students in the city. Let pA represent the population proportion of adults who live in the city who prefer pop music. Let pS represent the population proportion of students who live in the city who prefer pop music. Random samples of 200 adults from the city and 200 students from the city will be selected. Which of the following is the best interpretation of P(pˆA−pˆS>0)≈0.022 ?
Answer:
Answer E
Step-by-step explanation
The statement gives a probability of approximately 0.022 for the difference in sample proportions, pˆA−pˆS, being greater than 0.
The interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
Given :
pA is the population proportion of adults.pS is the population proportion of students.The total number of adults is 200 and the total number of students is also 200.The following steps can be used in order to determine the best interpretation of the given expression:
Step 1 - According to the given data, pA is the population proportion of adults who live in the city who prefer pop music.
Step 2 - Also given that pS is the population proportion of students who live in the city who prefer pop music.
Step 3 - So, the interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
