the monthly fees for single rooms at 5 colleges are $370, $310, $380, $340, and $310 respectively. what is the mean if these monthly fees?
The mean value of the data $370, $310, $380, $340, and $310 will be $342.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.
The monthly fees for single rooms at 5 colleges are $370, $310, $380, $340, and $310 respectively.
The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
The mean is given as,
Mean = (Sum of the observation) / (Total number of the observation)
The sum of the observation will be
Sum of the observation = $370 + $310 + $380 + $340 + $310
Sum of the observation = $1,710
The total number of the observation will be
Total number of the observation = 5
Then the mean of the data will be
Mean = $1,710 / 5
Mean = $342
Thus, the mean value of the data $370, $310, $380, $340, and $310 will be $342.

2 more than k is greater than -3 as an inequality
the inequality "2 more than k is greater than -3" can be represented as:[tex]\[ k + 2 > -3 \][/tex]
To translate the phrase "2 more than k is greater than -3" into an inequality, we can follow these steps:
1. Identify the expression "2 more than k."
2. Write the expression as an inequality where it is greater than -3.
Step 1: "2 more than k" translates to (k + 2).
Step 2: Since "2 more than k" is greater than -3, we write the inequality:
[tex]\[ k + 2 > -3 \][/tex]
So, the inequality "2 more than k is greater than -3" can be represented as:[tex]\[ k + 2 > -3 \][/tex]
a group of 4 students are selling candy bars to raise money for a field trip. the group needs to sell 53 candy bars. if each student sells an equal amount, how many candy bars do they get in all? interpret your remainder
Answer:
Each student is gonna sell 13 candy bars, and there is gonna be 1 bar unsold, because they sold equal amount of candy bars.Step-by-step explanation:
If there are 4 students, they need to sell 53 candy bars, and they will sell the same amount each one, we just have to divide:
[tex]\frac{53}{4} =13.25[/tex], or [tex]13\frac{1}{4}[/tex]
Because the division is not exact, we have a remainder of 1.
This can be interpreted as 1 candy is not sold, because they are gonna sell equally, so in that case each one would sell 13 candy bars, and one will be unsold.

When would you use a drawing of comparison bars for word problem
Answer: Comparison bars are a display tool for solving the scenario in which two elements are compared with the difference is either known or unknown.
There are three kinds of use of comparison bars in word problem such as 1) If difference is unknown then A-B=Difference[where A -bigger quantity, B-smaller quantity]. 2) If bigger quantity is unknown then A=Difference-B 3) If smaller quantity is unknown then B=Difference-A.
A drawing of comparison bars, also known as a bar graph, can be used in word problems when there is a need to compare different entities or categories. It is particularly useful in situations where quantitative data needs to be visually represented and compared. For example, if you are given data about the sales of different types of fruits in a grocery store, you can use a bar graph to compare the sales of each fruit.

what is 6 to the negative 1 times (-2) to the third power times (-4) to the negative 2
Given the following linear function sketch the graph of the function and find the domain and range f (x) =-5x+4
Both the domain and range of this function are all real numbers.
The two things that typically limit a domain are dividing by zero and taking the square root of a negative. Since this function does not have a square root or a denominator, then you must be able to use all real numbers.
The number z and −1.9 are additive inverses.
Drag and drop −1.9 and z to their correct positions on the number line.
Drag and drop the label “Sum” to the sum of −1.9 and z.
For z and -1.9 to be additive inverses, they must sum up to zero. Consequently, z should be 1.9, and both -1.9 and z (=1.9) placed on a number line would reflect their locations relative to zero. The sum of -1.9 and 1.9 would equal zero.
Explanation:In Mathematics, additive inverses are two numbers that add up to give zero. If the numbers z and -1.9 are additive inverses, this means that when added together, they produce the sum of zero. Therefore, z should be the opposite of -1.9, 1.9 on the number line.
The number -1.9 would appear on the left-hand side of the zero because it is a negative number. The number z (=1.9) would appear on the right-hand side of the zero because it's positive. According to the definition of additive inverses, the sum of these two numbers (-1.9 and 1.9) would be zero. So, 'Sum' would also be zero on the number line.

The number that would have 12. 75 being 25 percent of it would be 51.
How to find the number ?To find the number of which 12. 75 is 25 %, you can set up a proportion and solve for the unknown number ( let's call it " x ").
You can write the proportion as:
( 25 / 100 ) * x = 12. 75
Now, simplify the left side of the equation:
( 1 / 4 ) * x = 12.75
To solve for x, multiply both sides by 4 to isolate x:
x = 12. 75 * 4
x = 51
So, 12. 75 is 25% of the number 51.

The selling price of the new blend in $3.50 per pound and there is to be no difference in revenue from selling the new blend versus selling the other types. how many pounds of tge earl grey tea and orange pekoe tea are required
Final answer:
To find out how many pounds of Earl Grey tea and Orange Pekoe tea are required to make 400 pounds of the new blend, set up a system of equations based on the given information. Solve the equations to find the values of x and y.
Explanation:
To find out how many pounds of Earl Grey tea and Orange Pekoe tea are required to make 400 pounds of the new blend, we can set up a system of equations based on the given information.
Let x be the number of pounds of Earl Grey tea, and let y be the number of pounds of Orange Pekoe tea.
We know that the selling price of the new blend is $3.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types.
This means that the revenue from selling the Earl Grey tea and Orange Pekoe tea separately should be the same as the revenue from selling the new blend.
The revenue from selling the Earl Grey tea is 4x, and the revenue from selling the Orange Pekoe tea is 2y. So we have the equation 4x + 2y = 3.50 ×400.
We also know that the total weight of the new blend is 400 pounds, so we have the equation x + y = 400.
We can solve these two equations to find the values of x and y.

if b is between a and c find the value if x and bc when ab=3x bc=5x and ac=8
The value of x is 1, and the length of segment BC is 5 units.
If point B is between points A and C, then we can use the segment addition postulate to relate the lengths of segments AB, BC, and AC.
According to the segment addition postulate, the sum of the lengths of two segments that form a larger segment is equal to the length of the larger segment. In this case, we have:
AB + BC = AC
We're given that AB = 3x, BC = 5x, and AC = 8. Substituting these values into the equation:
3x + 5x = 8
Combine like terms:
8x = 8
Now, divide both sides by 8 to solve for x:
x = 8 / 8
x = 1
So, x is equal to 1.
Now that we know the value of x, we can find the length of segment BC:
BC = 5x
BC = 5 * 1
BC = 5

Recipe A makes 5 dinner rolls using 1 c of flour. Recipe C makes 45 rolls using 10 c of flour. Which recipe requires the most flour per roll?
When calculating how much flour is used per roll in each recipe, recipe C (at 0.22 cups per roll) uses more flour per roll than recipe A (at 0.2 cups per roll).
Explanation:To determine which recipe uses the most flour per roll, we first need to calculate the flour-per-roll for each recipe. For recipe A, it makes 5 dinner rolls using 1 cup of flour. So, the flour-per-roll for recipe A is
1 cup of flour ÷ 5 rolls = 0.2 cups per roll
. For recipe C, it makes 45 rolls using 10 cups of flour. So, the flour-per-roll for recipe C is
10 cups of flour ÷ 45 rolls = 0.22 cups per roll
. Comparative analysis shows that recipe C requires more flour per roll than recipe A.

Your football team gained 4 yards on first down and 2 yards on second down during its last possession. Which number is the additive inverse of the yards gained?
Final answer:
The additive inverse of 6 yards (4 yards on first down and 2 yards on second down) is -6 yards. A yard is a unit of length equal to 3 feet and is an SI Base Unit standard used in football.
Explanation:
The student is asking about the additive inverse of the yards gained in a football game. The additive inverse of a number is a number that, when added to the original number, will result in zero. In this case, the football team gained 4 yards on first down and 2 yards on second down, making a total of 4 + 2 = 6 yards. Therefore, the additive inverse of 6 yards is -6 yards because 6 + (-6) equals zero.
When considering SI Base Units, a yard is a unit of length equal to 3 feet. This is a predefined standard used internationally, and especially relevant in football, where moving the ball 10 yards results in a first down. This standardization ensures clarity and uniformity in the game, regardless of the location.
