Upper & lower bounds
Brian weighs himself at 84kg to the nearest kg.
What is the most he could weigh?
Give the upper bound as your answer.
Thus, the most he could weigh that is the upper bound of the given condition is 84kg.
What about weigh?
The word "weigh" is not frequently used by itself in arithmetic. The notion of weight or mass, for example, can be used when measuring or comparing quantities. While mass is a measurement of the quantity of matter inside an object, weight is a measure of the gravitational force acting on it. Weight can be viewed as the force a standard gravitational field applies to an object in the setting of measurement. Weight or mass may be denoted in mathematical equations by variables such as "w" or "m," and the units used to measure them may change based on the situation.
Define upper bound:
In mathematics, an upper bound is a number that is greater than or equal to all the elements in a given set. More formally, let S be a set of real numbers. A number u is an upper bound for S if and only if for all x in S, we have x ≤ u.
For example, consider the set S = {2, 4, 6, 8}. The number 10 is an upper bound for S because 2 ≤ 10, 4 ≤ 10, 6 ≤ 10, and 8 ≤ 10. However, the number 7 is not an upper bound for S because 8 > 7.
Note that an upper bound need not be an element of the set S itself. For instance, the set of all negative real numbers does not have any upper bound among the negative real numbers, but 0 is an upper bound for this set.
It's worth noting that an upper bound may or may not be a member of the set S. If an upper bound is a member of S, then it is called a "maximum" or "greatest" element of S. However, if an upper bound is not a member of S, then S has no maximum element.
According to the given information:
Brain weigh himself at 84kg to the nearest kg as (given) , because uses the method of round off.
Thus, the range of weigh:

(Adding Integers MC) What is the value of 209 + −142 + −52? 15 −15 67 −194
The answer is positive 15 because the final result is 15 units to the right of zero on the number line.
To solve this problem, we simply need to add the three integers together.
Starting with 209, we add -142 to get 67. Then, we add -52 to get a final result of 15. Therefore, the answer is 15.
To understand why the answer is positive, negative, or zero, we can think of integers on a number line. Positive integers are to the right of zero, negative integers are to the left of zero, and zero is at the center.
Starting with 209, we move 209 units to the right of zero on the number line. Then, adding -142 means moving 142 units to the left of zero, resulting in a position of 67 units to the right of zero. Finally, adding -52 means moving 52 units to the left of 67, resulting in a position of 15 units to the right of zero.
Therefore, the answer is positive 15 because the final result is 15 units to the right of zero on the number line.

The area of the rectangle is 220.5 square inches when the perimeter of the rectangle is 242/4 inch and one side of the rectangle is 49/4 inch.
Perimeter = [tex]60 \frac{2}{4}[/tex] inch = 242/4 inch
one side of rectangle = [tex]12\frac{1}{4}[/tex] inch = 49/4
The perimeter of a rectangle is the sum of all its sides. In this case, we know that the perimeter of the rectangle is 242/4 inch, which simplifies to 60.5 inch. We also know that one side of the rectangle is 49/4 inch.
Let's call the other side of the rectangle "n". Then, we can write the equation:
2(49/4 + n) = 60.5
Simplifying this equation, we get:
98/4 + 2n = 60.5
24.5 + 2n = 60.5
2n = 36
n = 18
Therefore, the other side of the rectangle is 18 inch.
To find the area of the rectangle, we can use the formula:
Area = length * width
In this case, the length is 49/4 inch and the width is 18 inch. So, we have:

Carlos has scored 24, 19, 20, and 28 points in his four basketball games so far. How many points does he need to score in the next game so that his average (mean) is 24 points per game?
Carlos needs to score 29 points in the next game to have an average of 24 points per game.
What is the mean and standard deviation?The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently, the squares of the differences are added.
According to the given information:Let x be the number of points Carlos needs to score in the next game to have an average of 24 points per game.
To find the solution, we can use the formula for the mean of a set of numbers:
(mean) = (sum of numbers) / (number of numbers)
In this case, we want the mean to be 24, and we have 5 numbers (4 previous game scores and the score in the next game), so:
24 = (24 + 19 + 20 + 28 + x) / 5
Multiplying both sides by 5, we get:
120 = 91 + x
Subtracting 91 from both sides, we get:
x = 29
Therefore, Carlos needs to score 29 points in the next game to have an average of 24 points per game.

When a raccoon eats 500 calories of food, some of those calories go towards its daily needs for warmth, movement, and reproduction. The raccoon's body does not store this energy; instead, it is transformed into other forms, including heat and movement. In addition, a portion of the energy in meals is expelled as waste rather of being absorbed. Nonetheless, 50 calories of the food's energy are transformed into biomass, which is then stored as fat or tissue in the raccoon's body.

The combinations of side lengths that will form a triangle with vertices X, Y, and Z are C and D.
For a set of three side lengths to form a triangle, the sum of any two sides must be greater than the third side. Using this property, we can determine which of the given combinations of side lengths will form a triangle with vertices X, Y, and Z.
A. XY = 8 mm, YZ = 12 mm, XZ = 23 mm
Here, XY + YZ = 8 mm + 12 mm = 20 mm, which is less than XZ = 23 mm. Therefore, this combination of side lengths will not form a triangle.
B. XY = 11 mm, YZ = 9 mm, XZ = 23 mm
Here, XY + YZ = 11 mm + 9 mm = 20 mm, which is less than XZ = 23 mm. Therefore, this combination of side lengths will not form a triangle.
C. XY = 11 mm, YZ = 12 mm, XZ = 20 mm
Here, XY + YZ = 11 mm + 12 mm = 23 mm, which is greater than XZ = 20 mm. Therefore, this combination of side lengths will form a triangle.
D. XY = 14 mm, YZ = 12 mm, XZ = 29 mm
Here, XY + YZ = 14 mm + 12 mm = 26 mm, which is greater than XZ = 29 mm. Therefore, this combination of side lengths will form a triangle.

What is confidence interval?
The proportion of probability, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn numerous times is referred to as the confidence level.
The given data is 3.7, 4.5, 4.1, 4.7, 3.9. Here n = 5
=> σ = 1- 95% = 5% = 0.05
We know that the confidence interval is
=> CI = [tex]\overline x {\displaystyle \pm }\frac{z(\sigma)}{\sqrt n}[/tex]
Here 95% confidence level so z= 1.96
Mean [tex]\overline x = \frac{3.7+4.5+4.1+3.9+4.7}{5} = 4.18[/tex] and σ = 0.5
Here n<30 so we can use t instead of z then t-value = 2.776.
Now confidence level CI = [tex]\ 4.18 {\displaystyle \pm }\frac{2.776\times0.5}{\sqrt 5}[/tex]
=> CI = 4.18 [tex]\display \pm[/tex] 0.62 = ( 3.56 , 4.80)
Hence the two sided confidence interval on mean is 3.56 and 4.80.

The gcf of 18,36 and me is 2.
I am a multiple of 5
I am greater than 18 and less than 30
Based on the information provided, the only possible number that satisfies all the conditions is 20.
What is GCF?
GCF stands for "Greatest Common Factor". It is also sometimes referred to as the "Greatest Common Divisor" (GCD). The GCF of two or more numbers is the largest positive integer that divides evenly into each of the numbers. In other words, it is the largest factor that the numbers have in common.
The GCF (Greatest Common Factor) of 18, 36, and a number N is 2. Since 18 and 36 are both even numbers with a common factor of 2, any number that satisfies this condition must also be even and have a factor of 2.
The number N is a multiple of 5. Since the number is even and has a factor of 2, the only even multiple of 5 between 18 and 30 is 20.
Finally, we are given that N is greater than 18 and less than 30. The only number that satisfies all the given conditions is therefore 20.

[tex]\frac{2}{3}a + 2 = \frac{1}{3}(4a + 1)[/tex]
solve for "a"
Answer:
a=5/2
Step-by-step explanation:
Answer:
a = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] a + 2 = [tex]\frac{1}{3}[/tex] (4a + 1)
multiply through by 3 to clear the fractions
2a + 6 = 4a + 1 ( subtract 4a from both sides )
- 2a + 6 = 1 ( subtract 6 from both sides )
- 2a = - 5 ( divide both sides by - 2 )
a = [tex]\frac{-5}{-2}[/tex] = [tex]\frac{5}{2}[/tex]
