Final answer:
The lower bound of the number rounded to 2 decimal places is 45.54, and the upper bound is 45.56.
Explanation:
To find the lower and upper bounds of a number when it is rounded to 2 decimal places, we need to consider the two possible values that round down and round up from the given number.
In this case, the number is 45.55.
The lower bound is the number rounded down.
When we round down 45.55 to 2 decimal places, we get 45.54.
The upper bound is the number rounded up.
When we round up 45.55 to 2 decimal places, we get 45.56.

Martin's class needs to raise $1,250 for a river rafting trip. To find how much money each of class members must raise, Martin divides 1,250 by 25. His steps are shown 1.250 25 Step 1: (1,000 + 200 +50) = 25 Step 2: (1,000 - 25) + (200 - 25) + (50 25) Step 3: 400 + 8 + 2 Step 4: 482 In which step did Martin make his first mistake! F Step 1 G Step 2 H Step 3 J Step 4
Answer:
F) Step 1
Step-by-step explanation:
1,000+200+50=1,250, not 25
Martin made his first mistake in Step 2.
Explanation:Martin made his first mistake in Step 2.
In Step 2, Martin subtracted 25 from both 1,000 and 200, correctly. However, for the third number, 50 / 25 is actually 2, not 25. Therefore, the correct calculation should be (50 / 25) instead of (50 - 25).
So, the correct calculation in Step 2 should be (1,000 - 25) + (200 - 25) + (50 / 25) = 975 + 175 + 2 = 1,152.

Answer:
Your answer is correct. (x-4)^2 = 3
Step-by-step explanation:
x^2 - 8x + 13 (is not a perfect square so you need to move the 13 to the right by subtraction)
x^2 - 8x + ____ = -13 (In order to get A, divide the second coefficient by 2. That would be -4 in this case. Now we need to square A to find the constant. That would be 16)
(x^2 - 8x + 16) = -13 + 16 (Whatever we do on the left we add on the right, -13+16 = 3)

6. A cone has a diameter of 6 inches and a height of 8 inches. Find the
volume using 3.14 for Tr. *
Final answer:
To calculate the volume of a cone with a diameter of 6 inches and a height of 8 inches, use the radius which is 3 inches and apply the formula V = 1/3πr²h, resulting in a volume of 226.08 cubic inches.
Explanation:
The subject's question is about finding the volume of a cone with a given diameter and height. The formula to calculate the volume of a cone is V = ⅓πr²h. Given that the diameter is 6 inches, the radius (r) is half of that, which is 3 inches. Using 3.14 for π (pi), and the given height (h) of 8 inches, we can substitute these values into the formula to find the volume.
So, the calculation is:
Find the radius (r) by dividing the diameter by 2, r = 3 inches.
Substitute r and h into the volume formula: V = ⅓πr²h = ⅓(3.14)(3 inches)²(8 inches).
Calculate the square of the radius (3 inches)² = 9 inches².
Multiply the area with height and π: V = ⅓(3.14)(9 inches²)(8 inches) = 226.08 cubic inches.
Therefore, the volume of the cone is 226.08 cubic inches.
A rectangle has a height of 5 and a width of 4x2 – 2x – 6.
Express the area of the entire rectangle
Expression should be expanded.
Answer:
The area of the rectangle is given by the expression "20x² - 10x - 30".
Step-by-step explanation:
The area of a rectangle is given by the product of it's dimensions. This is shown in the formula bellow:
area = width*height
In this case the width is an expression, so we need to multiply the numeric part of each mnemonic
area = 5*(4x² - 2x - 6)
area = 20x² - 10x - 30
The area of the rectangle is given by the expression "20x² - 10x - 30".

Lucy has the spinner pictured and
spins it twice in a row. What is the
probability that she lands on blue
first and then on yellow or green?
Answer:
d
Step-by-step explanation:
Final answer:
To find the probability of landing on blue first and then on yellow or green, one must multiply the probability of landing on blue by the combined probability of landing on yellow or green. However, exact probabilities cannot be provided without more information about the spinner.
Explanation:
The student is asking about the probability of a sequence of events occurring with a spinner. To calculate the probability of landing on blue first and then on yellow or green on the second spin, we must first know the individual probabilities of landing on each color. Assuming the spinner is fair and has equal sections for each color, the probability of landing on blue on the first spin (P(B)) and the probability of landing on yellow (P(Y)) or green (P(G)) on the second spin need to be calculated separately.
The probability of two independent events occurring in sequence is the product of their individual probabilities. Therefore, if the probability of landing on blue first is P(B), and the combined probability of landing on either yellow or green on the second spin is P(Y or G), then the total probability of the sequence is P(B) multiplied by P(Y or G). However, without the exact probabilities or a clear description of the spinner, we cannot provide a numerical answer.
A zookeeper created the following stem-and-leaf plot showing the number of tigers at each major zoo in the country:
Answer:
So the smallest number of tigers at any zoos is 7
Step-by-step explanation:
As we can see:
the data represented in the 0's is given by 7 the data represented in the 10's is given by 11 14 18 the data represented in the 20's is given by 25 25 25 26 27 27 29the data represented in the 30's is none the data represented in the 40's is noneSo the smallest number of tigers at any zoos is 7
A stem-and-leaf plot is a tool used in mathematics to organize and interpret data. In this case, it's used to understand the distribution of tigers in major zoos across the country and can help find modes, medians, ranges for the dataset.
Explanation:The question refers to a stem-and-leaf plot, a graphical tool widely used in mathematics for organizing and interpreting data. It's often used in middle school to introduce students to basics of statistics. In the context of this specific problem, the 'stems' would represent the tens place of the number of tigers and the 'leaves' would represent the ones place.
For example, a stem of 2 and a leaf of 3 would represent 23 tigers. When compiled, this plot provides an overview of the distribution of tigers in major zoos across the country. This type of graph is extensively useful for finding modes, medians, and ranges for data sets.

During his career, Walter Payton rushed for 16,726 yards. How many feet is that? I WILL GIVE BRAINLIEST!!!!!!!!
Step-by-step explanation:
1 yard = 3 feet so we will multiply 16726 yards with 3 so answer = 16726 × 3 = 50178
Final answer:
To convert yards to feet, multiply the number of yards by 3. Walter Payton rushed for 16,726 yards, which equals 50,178 feet when converted.
Explanation:
The question asks to convert the number of yards rushed by Walter Payton during his career into feet. To find the conversion, you can use the fact that there are 3 feet in 1 yard. Therefore, to convert yards to feet, you should multiply the number of yards by 3.
Walter Payton rushed for 16,726 yards during his career. Using the conversion factor:
Feet = Yards × 3So,
Feet = 16,726 yards × 3
Feet = 50,178 feet
Thus, Walter Payton rushed for 50,178 feet during his career.
