Round 4,929 to the place value of the underlined digit.
Raising 4,929 to the place value of the underlined digit will give a value of 4930.
What is rounding up of numbers?It should be noted that rounding up of numbers simply means raising the number to the nearest ten, hundred, or thousand.
In this case let's assume that the underlined number is 2. Therefore, raising 4929 will give 4940. It should be noted that the number beside it is more than 5. Therefore, 1 will be added to 2 making 3. The new number is 4930.

All i need to know is question 5. How they are different.
The $2 and $3 profits from the sale of sandwiches and wraps respectively, and the equation that is used to calculate the profit gives;
1. The equation is; [tex] \displaystyle{y = 490 - \frac{2}{3} \cdot x}[/tex]
The slope, m = [tex] \displaystyle{ - \frac{2}{3}}[/tex]
The y–intercept, c = 490
2. The graph can be drawn by joining the y–intercept to a point found by moving along the slope from the y–intercept
3. [tex] \displaystyle{f(x) = 490 - \frac{2}{3} \cdot x}[/tex]
4. Please find attached the graph of the number of wraps to the number of sandwiches
5. Please find attached the combined graph of the two functions
The similarity is the common slope
The difference is the y–intercept
What is the slope of a straight line graph?The slope is the ratio of the rise to the run of the graph.
The given function is; 2•x + 3•y = 1470
Where;
x = The number of sandwich sold
y = The number of wraps sold
The profit per sandwich sale = $2
Profit per each wrap sale = $3
1. The slope and intercept form is; y = m•x + c
Where;
m = The slope
c = The y–intercept
Therefore, 2•x + 3•y = 1470 gives;
3•y = 1470 - 2•x
y = (1470 - 2•x)÷3 = 490 - (2/3)•x
[tex] \displaystyle{y = \frac{1470-2\cdot x}{3} = 490 - \frac{2}{3} \cdot x}[/tex]
Therefore;
[tex] \displaystyle{y = 490 - \frac{2}{3} \cdot x}[/tex]By comparison, we have;
The slope, m = -2/3The y-intercept, c = 4902. Using the slope and intercept method to graph the line involves the following steps.
Mark the point (0, 490) on the graph to represent the y–interceptFrom the point (0, 490), move 2 units downwards and 3 units to the right to represent the slope of (-2/3) then mark a point at the location arrived at, which is (3, 488)Join the two points and extend the line to complete the graph3. The equation in function notation is; [tex] \displaystyle{f(x) = 490 - \frac{2}{3} \cdot x}[/tex]
The meaning of the function is that the number of wraps sold is given by the difference between 490 and two thirds of the number of sandwiches sold, or that as the number of sandwiches sold increases by by 1, the number of wraps sold decreases by 2/3
4. The graph can be created using a spreadsheet application

Given that the equation of the graph of the previous month is y = 490 - (2/3)•x, we have;

you are given the following information obtained from a random sample of four observations selected from a large, normally distributed population. 25 47 32 56
The 95% confidence interval for the mean of the population lies between
(17.61, 62.39)
Construct a 95% confidence interval for the mean:
To construct a 95% confidence interval for the mean of the population, we must start with finding the following:
Mean
n=4
Mean=(25+47+32+56)/n
=(160)/4
=40
Mean is 40
Standard deviation σ
= [tex]\frac{1}{n-1}( \sum x^{2} -n(mean)^{2} )[/tex]
= [tex]\frac{1}{3} (6994-4(40)^{2} )[/tex]
σ= 14.07
Now, we construct 95% confidence interval CI:
Confidence interval=mean± t-table value*(standard deviation/√n)
Given a t-table value of 3.1824 from z-distribution table, mean=40, n=4, and standard deviation=14.07, we have:
Confidence interval=(40±3.1824(14.07/√4)

five fair dice were tossed, and the sum of the resulting tosses was recorded. this process was repeated 10,000 times using a computer simulation. the number of times the sum of the five tosses equaled 26 was 53. what is the estimated probability that the sum of the five dice will be 26? (give the answer to four decimal places.)
The estimated probability that the sum of five dice will be 26 is 0.0053
What is meant by Estimated Probability?Estimated Probability: Estimated probability is an approximation, or estimate, of theoretical probability. The larger the number of trials, the more accurate we expect this approximation to be. If E consists of a single outcome s, we refer to P(E) as the probability of the outcome s, and write P(s) for P(E)
N = Number of Repeated Process = 10,000
n = Number of times the sum of the five tosses equaled 26 = 53
The estimated probability that the sum of the five dice will be 26 = n/N
Where n = 53
And N = 10,000
Using the above formula, we have the following:-
n/N becomes
n/N = 53/10,000
n/N = 0.0053
Hence, the estimated probability that the sum of five dice will be 26 is 0.0053

Solve number 15? , Find the equation for the indicted variable, the answer will look something like this “h=_____”. So it is “h” equals something
Answer:
[tex]h = \dfrac{T - r}{n}\\\\\text{Hourly rate } = \$45\;\;\text{if T = 200, r = 20 and n= 4}[/tex]
Step-by-step explanation:
We have from #14 that
T = r + nh
where T = amount charged, n = hours worked, r = fixed rate and h = hourly rate
Subtract r from both sides:
T - r = r + nh - r
The r terms on RHS of the equation cancel out
T - r = nh
Divide both sides by n:
(T - r)/n = h
Or we can write it as
h = (T - r)/n
If r = 20, , T = 200 and n =4 we get by substitution
h = (200-20)/4
h = 180/4
h = 45
So hourly rate = $45
suppose f(x)=4x-2 and g(x)=-2x+1
find the value of f(3)/g(-4)
Answer:
10/9
Step-by-step explanation:
We can calculate f(3) and g(-4)
f(3) = 4*3 - 2 = 12 - 2 =10
and g(-4) = -2 * (-4) + 1 = 8 + 1 = 9
Then it is easy to calculate f(3)/g(-4):
f(3)/g(-4) = 10/9
where we use the values which we calculated before.
⇒In the equation f(x) given f(3) plug in the value 3 in the place of x and simplify
[tex]f(3)=4(3)-2\\f(3)=12-2\\F(3)=10[/tex]
⇒For g(-4) in the place of x plug in -4 in the equation of g
[tex]g(-4)=-2(-4)+1\\g(-4)=8+1\\g(-4)=9[/tex]
Now we can find the value of of the problem as done BELOW:

In the given groups of Relative Frequencies the best represented by a pie chart would be Option D. 25%; 24%; 26%; 25%.
What are Relative Frequencies?Relative frequencies are more commonly used because they allow you to compare how frequently values occur relative to the overall sample size. They are calculated by dividing the total number of responses by the number of responses for each category. Pie charts depict relative frequencies by showing how much of the total pie each category represents. Raw frequencies and relative frequencies can be displayed in frequency tables and bar charts.
According to the question we can get,
25% = [tex]\frac{1}{4}[/tex]
[tex]\frac{1}{4}[/tex] × 360° = 90°
24% approach 25%

Before the pandemic liana can sanitize their guest room in 45minutes, and gab her brother can do the work in 30 minutes how long will take them finish the same work
They will together take 18 minutes to finish the sanitization work together.
It is mentioned that Liana can sanitize the guest room in 45 minutes only and Gab, her brother, can do the same in 30 minutes.
Let they take y minutes to finish the work together.
Let the total work be m
Workdone by Liana in 45 mintues = m
∴Workdone in 1 minute = m / 45
Workdone by Gab in 30 minutes = m
∴Workdone by Gab in 1 minute = m / 30
Let the total time taken by them = x minutes.
Total time taken by them together = m / 45 + m / 30
∴ [tex]\frac{m}{45} +\frac{m}{30} = \frac{m}{x}[/tex]
⇒ [tex]\frac{1}{45} +\frac{1}{30} = \frac{1}{x}[/tex]
LCM of 45 and 30 is 90

a machine can pack a 3 ft by 3 ft by 1 ft carton with packing material in 3 seconds Then it would take 32 seconds to fill a carton that measures 4 ft by 4 ft by 6 ft
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 3 ft * 1 ft=9 ft³
Therefore:
A machine can fill 9 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 4 ft * 6 ft=96 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
9 ft³---------------------3 seconds
