Ms. Michaels surveyed her class on whether they preferred free time at the beginning of class or at the end of class. If the ratio of students who prefer free time at the beginning of class to students who prefer free time at the end of class is 12 over 19, what does the ratio 12 over 19 represent?
A19 students prefer free time at the beginning of class, and 12 students prefer free time at the end of class.
B 19 students prefer free time at the beginning of class, and 31 students prefer free time at the end of class.
C 12 students prefer free time at the beginning of class, and 19 students prefer free time at the end of class.
D 31 students prefer free time at the beginning of class, and 12 students prefer free time at the end of class.
The ratio 12/19 means 12 students prefer free time at the beginning of the class and 19 students prefer free time at the end of the class. (option C)
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The general form of representing a ratio of between two quantities say 'a' and 'b' is a: b, which is read as 'a is to b'.
For example if the ratio of boys to girls in a school is 5:4, this means in the school 5boys to 4 girls , and 10boys to 8girls. It can also be expressed as 5/4
Therefore if 12/1,9 is the ratio of students that prefer free time at the beginning to students that prefer free time at the end of a class, then , 12 students prefer free time at the beginning and 19 prefer at the end of the class.

Define Algebraic Expression
The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it. In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).
Given expression,
-2/9 x=2/5
Isolate the variable, x
x = (2 * 9) / ( 5 * -2)
x = - (9/5) or -1 4/5
Hence, the value of x is -1 4/5 i.e, option(A)

A submarine is 75 feet below sea level. It descends another 25 feet every 10 seconds for 3 minutes. What integer represents the submarines current location?
The integer represents the submarine's current location is -525 feet
The initial position of submarine = 75 feet below sea level
The descending rate of submarine = 25 feet every 10 second
Total time = 3 minutes
One minute = 60 seconds
3 minutes = 180 seconds
Therefore number of 10 seconds period = 180 / 10
= 18
For each 10 second the submarine descend 25 feet
Total distance that submarine descend = 18 × 25
= 450 feet
The initial position of submarine = -75
Current position = -75 - 450
= -525 feet
Hence, the integer represents the submarine's current location is -525 feet

7 hours long was the trip for Imani to drove to the lake and back.
Speed is rate of change of position of any object from place to another . Formula to calculate speed is
Speed = Distance / Time
Speed at which he drove to the lake = 30Km/h
Speed at which he drove back = 40Km/h
Time taken in returning back from the trip = 3 hours
Distance travelled when time taken is 3 hours and speed is 40Km/h = Speed ×Time taken =

a simple random sample of 40 items resulted in a sample mean of 25. the population standard deviation is 5. what is the standard error of the mean? (round your answer to two decimal places).
The standard error of the mean is approximately 0.79 (rounded to two decimal places).
Define standard error ?
The standard error is a statistical term that measures the variability of a sample mean or an estimate of a population parameter from its true value. It is the standard deviation of the sampling distribution of the mean. In simpler terms, the standard error measures how much the sample mean varies from the true population mean. A smaller standard error indicates that the sample mean is more likely to be representative of the population mean, while a larger standard error suggests that the sample mean may not be as reliable.
The formula for the standard error of the mean is:
[tex]SE = \frac{\sigma }{\sqrt{n}}[/tex]
Where σ is the population standard deviation and n is the sample size.
Substituting the given values:
[tex]SE =\frac{5}{\sqrt{40}}[/tex]
SE ≈ 0.79
Therefore, the standard error of the mean is approximately 0.79 (rounded to two decimal places).

A furniture maker uses the specification 19.8≤w≤20.2 for the width, w, in inches of a desk drawer. Write the specification as an absolute value inequality.
Answer:
Step-by-step explanation:
The correct answer is:
|w-20| ≤ 0.12.
Explanation:
We first find the average of the two ends of the inequality:
(19.88+20.12)/2 = 40/2 = 20
This will be the number subtracted from w in the inequality.
Now we find the difference between this value and the ends:
20-19.88 = 0.12
20.12 - 20 = 0.12
This will be what our absolute value inequality ends with; the "answer" part, so to speak.
Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."
This gives us
|w-20| ≤ 0.12
Martin has $30 and he makes $10 an hour mowing grass. His friend has $60 and makes $7 an hour babysitting. After how many hours will Martin have more money?
Martin will have more-money than his friend after babysitting for 10 hours
How to determine the relationship equation?The given parameters in the question are:
Martin
Initial amount = $30
Additional earnings = $10
His friend
Initial amount = $60
Additional earnings = $7
The equation that shows their total earnings is
y = Initial amount + Additional earnings * x
So, we have
Martins: y = 30 + 10x
His friend: y = 60 + 7x
When Martin has more money, we have
Martins > His friend
This gives
30 + 10x > 60 + 7x
Evaluate the like terms in the above inequality
3x > 30
Divide by 3

she plans to spend some of all of the money she has left to buy new biking outfits for $45.35 each
The number of outfits that Gianna can buy given her budget is 8.
How many outfits can she buy?The first step is to determine the total cost of the items bought so far
Total cost = price of the bicycle + cost of the bicycle reflectors + cost of the bike gloves
Cost of the bicycle reflectors = cost of one reflector x 2
Cost of the bicycle reflectors = $10.01 x 2 = $20.02
Total cost = $20.02 + $356.46 + $20.72 = $397.20
Amount that is left to buy the outfits = amount Gianna has - total cost
$760 - $397.20 = $362.80
Number of outfits she can buy = amount left / cost of one outfit
Number of outfits she can buy = $362.80 / $45.35
Number of outfits she can buy = 8
