Callie will have $104.12 less than what she earned each month.
<h3>What are Rational Numbers ?</h3>
A number which can be represented in the form p/q where q ≠ 0 are called Rational Numbers.
The complete question is
Callie was billed $416.48 for car repairs. She will pay the service center in 4 equal monthly installments from her bank account.
What is the net change in her bank account balance after each monthly payment? The net change to Callie’s bank account is -$416.48.
The negative sign indicates money leaving Callie’s account. Which rational number represents the number of months that Callie has to pay off the bill? What does the sign on the number mean?
Write an expression to represent the net change to Callie’s account balance each month.
The number of months Callie has to pay the bill is for 4 months, as there are 4 equal installments
The net change in account in Callie's Account balance each month is
-$416.48 / 4 = -$104.12.
The (-) sign indicate the reduction of the net balance from her account.
Callie will have $104.12 less than what she earned each month.

Answer:
y = -6
Step-by-step explanation:
-2y+2 = -2(3y+11)
-2y+2 = -6y - 22
4y +2 = -22
4y = -24
y = -6
Answer: 2(2y+5)
Explanation:
One possible factorization is 2(2y+5)=4y+10, which would correspond to a set of dimensions 2 by (2y+5) for the rectangle.
Note that this is only one of many possibilities to come up with the dimensions. For example another possibility would be 1*(4y+10), or 4*(y+2.5). In fact, in Real numbers, there are infinitely many possible rectangles with a particular area.
Add 7 to both sides of the equal sign to get a positive 27
Using the Empirical Rule, it is found that there is a 68% probability that a student scored between 66 and 82.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, considering the mean of 74 and the standard deviation of 8, we have that:
74 - 8 = 66
74 + 8 = 82.
Hence, there is a 68% probability that a student scored between 66 and 82.
