I think you would do 897 divided by 50. Tell me if im wrong.
To find the number of steps between each landing in an 897-step stairwell with 50 landings, divide the total steps by the number of segments, resulting in approximately 17 to 18 steps per segment.
Step by Step Solution:
To determine how many steps are between each landing in an 897-step stairwell with 50 landings, follow these steps:
First, note that there are 50 landings, which divide the stairwell into 51 segments (since the top step is considered the last segment).Then, divide the total number of steps by the number of segments: 897 steps / 51 segments = 17.588 steps per segment.Since you can't have a fraction of a step, you may need to adjust for some rounding. Usually, some segments may have 17 steps and others may have 18 steps to total correctly.Therefore, each segment will have approximately 17 or 18 steps.

y=mx+b is the slope-intercept form where m is the slope and b is the y-intercept.
Given that m (the slope) = 9 and b (the y-intercept) = 5, we can substitute directly into the equation and get this answer:
y=9x+5
What number multiplied by 8 will give a product of 9.6?
Answer:
1.2
Step-by-step explanation:
Write out the equation and let mbe the missing number:
8 × m = 9.6
Divide 8 to both sides:
[tex]\frac{8}{8}[/tex] × m = [tex]\frac{9.6}{8}[/tex]
Simplify for M
m = 1.2
The number that needs to be multiplied by 8 to yield the product of 9.6 is 1.2. This is calculated by dividing 9.6 by 8.
Explanation:The student is asking to solve for a number that when multiplied by 8 results in the product of 9.6. This can be solved by a straightforward division operation. When we say, 'a number multiplied by 8 equals 9.6', we're actually writing an equation for multiplication. To get that number, we'll need to divide 9.6 by 8 because division is the inverse operation of multiplication.
Here's how you do it, step-by-step:
Write down the division operation of 9.6 ÷ 8. Perform the division.
The solution to 9.6 ÷ 8 is 1.2. So, the number multiplied by 8 to get 9.6 is 1.2.

3x-61=2x-50
I need the answer
Answer: [tex]x = 11[/tex]
Solving for variable x
Move all terms containing x to the left, all other terms to the right
Add -2x to each side of the equation
[tex]-61 + 3x + -2x = -50 + 2x + -2x[/tex]
Combine like terms: 3x + -2x = 1x
[tex]-61 + 1x = -50 + 2x + -2x[/tex]
Combine like terms: 2x + -2x = 0
[tex]-61 + 1x = -50 + 0\\-61 + 1x = -50[/tex]
Add 61 to each side of the equation.
[tex]-61 + 61 + 1x = -50 + 61[/tex]
Combine like terms: -61 + 61 = 0
[tex]0 + 1x = -50 + 61\\1x = -50 + 61[/tex]
Combine like terms: -50 + 61 = 11
[tex]1x = 11[/tex]
Divide each side by 1

Two friends shop for fresh fruit. Jackson buys a watermelon for $8.85 and 3 pounds of cherries. Tim buys a pineapple for $3.35 and 2 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Jackson spent.
Answer + Step-by-step explanation:
Jackson spent $8.85 on watermelon and p*3 dollars on cherries, which simplifies to 8.85 + 3p dollars.
Tim spent $3.35 on pineapple and p*2 dollars on cherries, which simplifies to 3.35 + 2p dollars.
To find how much more Jackson spent than Tim, we can subtract Tim's total cost from Jackson's total cost, giving:
(8.85 + 3p) - (3.35 + 2p) = 5.50 + p
So Jackson spent $5.50 + p more than Tim.

Suppose you want to simulate surveying 100 people to find the date of the month (1st, 2nd, 3rd, . . .) each was born. You decide to simulate the survey by having your computer randomly list values 1 through 31. Would the simulation provide a fair representation of an actual survey of 100 people? Why or why not?
Yes, because all possible dates of the month would be represented.
No, because for the 12 months in the year not all of the dates are represented. No, because for the 12 months in the year each date is not equally likely.
Yes, because it is possible to get 100 random values in a simulation.
Answer:
No, because for the 12 months in the year each date is not equally likely.
Step-by-step explanation:
Not all months have 31 days, meaning that numbers as high as 31 will not be as common.
The proposed simulation overlooking the fact that not all months have 31 days, results in a bias for the dates 29th, 30th, and 31st. Therefore, it wouldn't represent the actual survey accurately.
Explanation:The simulation proposed would not provide a fair representation of an actual survey of 100 people for their birth dates. This is rooted in the fact that not all months have 31 days. The assumption of the simulation means that the dates from 1 through 31 have an equal likelihood of being selected, ignoring the fact that in reality, dates like the 30th and 31st may not be possible for all months. An accurate simulation would require consideration for these variations, meaning dates 1 through 28 should be uniformly represented, with the 29th, 30th, and 31st having conditional probabilities based on the month.

The current year’s depreciation expense using the straight-line method and assuming only one depreciable property, is P20,000. What is the machine’s useful life when it was purchased for P200,000 with a salvage value of P20,000?
Answer:
Machine's useful number of years = 9 years
Step-by-step explanation:
Using the straight line method, depreciation is calculated as the difference between the cost of the equipment minus the salvage value, all divided by the number of useful years.
Yearly Depreciation
= (Cost - Salvage value) ÷ (Number of useful years)
Yearly depreciation = P20,000
Cost = P200,000
Salvage Value = P20,000
Number of useful years = n
20000 = (200000 - 20000) ÷ n
20000 = (180000/n)
n = (180000/20000) = 9 years

My three friends and I have dinner together every weekend. Each weekend, two of us cook and the other two clean up afterwards. How many different ways are there for us to choose who cooks and who cleans?
Final answer:
To find the number of different ways for the four friends to choose who cooks and who cleans, one can use combinators to calculate that there are 6 different combinations.
Explanation:
The student asked, "My three friends and I have dinner together every weekend. Each weekend, two of us cook and the other two clean up afterwards. How many different ways are there for us to choose who cooks and who cleans?" To solve this, we can use combinatorics, which is a branch of mathematics dealing with combinations of objects belonging to a finite set in accordance with certain constraints.
There are four friends, so we want to know in how many ways we can select two of them to cook. The number of ways to choose the two people who will cook can be calculated using the formula for combinations, which is C(n, k) = n! / (k! * (n-k)!), where n is the total number of items, and k is the number of items to choose.
Here, n would be 4 (since there are four friends), and we want to choose 2 (the number of friends who will cook), so we get C(4, 2) = 4! / (2! * (4-2)!) = (4 * 3) / (2 * 1) = 6 ways to choose cooks. The other two automatically become the cleaners. So, there are 6 different ways for the four friends to choose who cooks and who cleans.

Gabriella asked 555 of her hundreds of coworkers how much storage space they were currently using on their computer. Here are their responses (in gigabytes): 4, 8, 8, 9, 114,8,8,9,114, comma, 8, comma, 8, comma, 9, comma, 11 The mean of these amounts is \bar x=8 x ˉ =8x, with, \bar, on top, equals, 8 gigabytes. What is the standard deviation? Round your answer to two decimal places. s_x\approxs x ≈s, start subscript, x, end subscript, approximately equals gigabytes
Answer:
The standard deviation of the sample is 2.55 gigabytes
Step-by-step explanation:
Here we have the responses as follows;
Storage space usage on their computer [tex]x_i[/tex]
The number of respondents or sample size, n = 5
[tex]x_i[/tex] [tex](x_i - \bar x)[/tex] [tex](x_i - \bar x)^{2}[/tex]
4 -4 16
8 0 0
8 0 0
9 1 1
11 3 9
∑ 40 26
The sum = ∑X = 4 + 8 + 8 + 9 + 11 = 40
The mean = (The sum)/(The count) = 40/5 = 8
Formula for population standard deviation is;
[tex]\sigma = \sqrt{\frac{\Sigma (x_i - \mu)^2}{n } }[/tex]
Where:
σ = Population standard deviation
μ = Population mean
Since we are dealing with only 5 out of her hundreds of coworkers we are dealing with a sample therefore;
The formula for sample standard deviation is;
[tex]s = \sqrt{\frac{\Sigma (x_i - \bar x)^2}{n - 1} }[/tex]
Where:
s = Sample standard deviation
n = Sample size
[tex]x_i[/tex] = Each value of the sample
[tex]\bar x[/tex] = Sample mean
We find each value of [tex](x_i - \bar x)[/tex] by subtracting the x values from the mean, 8, as in the table above, next we find [tex](x_i - \bar x)^{2}[/tex] by squaring the [tex](x_i - \bar x)[/tex].
Next, we find the sum of the differences from the mean square values from the table after which we divide by n - 1, to get [tex]{\frac{\Sigma (x_i - \bar x)^2}{n - 1} } = \frac{26}{5 - 1} = \frac{26}{4} = 6.5[/tex]
We find the root of the result which gives us the standard deviation hence
√6.5 = 2.5495.
Standard deviation, s = 2.5495 ≈ 2.55 to two significant places of decimal.
After making a table for summation the standard deviation of the sample is 2.55 gigabytes.
Use the formula for population standard deviation is:
[tex]\sqrt{\dfrac{\sum{(x_i - \mu)^2}}{n}[/tex]
Where:
σ = Population standard deviation
μ = Population mean
The formula for sample standard deviation is;
[tex]\sqrt{\dfrac{\sum{(x_i - X)^2}}{n-1}[/tex]
Where:
s = Sample standard deviation
n = Sample size
[tex]x_i[/tex] = Each value of the sample
X = Sample mean
Since we are dealing with only 5 out of her hundreds of coworkers we are dealing with a sample, therefore;
The storage used is represented by [tex]x_i[/tex]
The number of respondents or sample size represented by n
Then n = 5
The table for summation is attached below.
Find the sum of the differences from the mean square values from the table after which we divide by n - 1,
[tex]\dfrac{\sum{(x_i - X)^2}}{n-1} = \dfrac{26}{5-1}\\\\\dfrac{\sum{(x_i - X)^2}}{n-1} =6.5[/tex]
Find the root of the result which gives us the standard deviation hence
√6.5 = 2.5495.
Hence,
Standard deviation,
s ≈ 2.55 about two significant places of decimal.
