Step-by-step explanation:
Line graphs easily help the visual learner to interpret data and understand peaks and decreases in certain levels. It connects data points and allows people to see what is actually going on.
Answer:
line graph
Step-by-step explanation:
The explanations of each plot are:
Scatter plot
It is used to see the correlation between two variables. The correlation can be positive (increases), negative (decreases) or zero (no correlation at all). This plot can be used to draw a trend line to study the correlation between variables using an equation, generally a line and which prosses is call line regression.
Line graph
Is like the scatter plot but instead of leaving the data or points without connection the line graph connects the points, representing the data, with a line, so to easily show a tendency between variables, which generally tends to increase.
This plot is an easy way to show a tendency, but the scatter plot can give more statistical information about a correlation between variables.
box-and-whisker plot
Shows the median and the quartiles of the data, i.e. shows a interval in which the recollected data can be found and its frequency of repetition.
stem-and-leaf plot
Allows to simultaneously see the frequency distribution of the variable and its graphic representation and its constructed by separating, in each data, the last digit of the right (the leaf) to the remaining digits (the Stem).
So, to easily show numerical data in ascending order it can be used the line graph, but it can be used de scatter plot to give deeper statistical information too.
A cabin cruiser travels 48 miles upstream (against the current) and 48 miles downstream (with the current). The speed of the current is 4 miles per hour. Find the total time traveled if the cabin cruiser travels at 12 miles per hour in still water.
The answer is:
The total time traveled is equal to 9 hours.
Why?To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.
So, we need to write two equations:
Let be "x" the speed of the cabin cruiser (12 mph in still water)
Let be "y" the speed of the current (4 mph).
Then,
For the travel against the current (upstream), we have:
[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]
For the travel with the current (downstream), we have:
[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]
Also, we know that the speed of the cruise traveling in still water is equal to 12mph.
So,
Calculating the time traveled upstream, we have:
[tex](x-4mph)*t_{upstream}=48miles[/tex]
[tex](12mph-4mph)*t_{upstream}=48miles[/tex]
[tex](8mph)*t_{upstream}=48miles[/tex]
[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]
Calculating the time traveled downstream, we have:
[tex](x+4mph)*t_{downstream}=48miles[/tex]
[tex](12mph+4mph)*t_{downstream}=48miles[/tex]
[tex](16mph)*t_{downstream}=48miles[/tex]
[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]
Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:
[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]
Hence, we have that the total time traveled is equal to 9 hours.

A store marks up merchandise 40% to make a profit. If the item costs the store $12, what is the selling price?
Answer:
$16.80
Step-by-step explanation:
The item costs the store $12.00
12 x 40% or 12 x 0.4 = 4.8
Add 4.8 to 12
And you get the price the store sells the product for profit, $16.80

Find the surface area of the right square pyramid. Round your answer to the nearest hundredth.
ANSWER
C. 145.75 yd²
EXPLANATION
First we need to calculate the area of the four triangular faces.
The lateral surface area
[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]
[tex] = 117.66 {yd}^{2} [/tex]
The area of the base is
[tex] = 5.3 \times 5.3[/tex]
[tex] = 28.09[/tex]
To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.
Therefore the total surface area is
[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]
Answer: Option C.
Step-by-step explanation:
To calculate the surface area of the right square pyramid, you need to use the following formula:
[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]
Where "s" is the length of any side of the base and "l" is the slant height.
You can identify in the figure that:
[tex]s=5.3yd\\l=11.1yd[/tex]
Therefore, substituting these values into the formula, you get this result:
[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]
Express each ratio as a unit rate. Round to the nearest tenth or cent.

The last time Esteban checked his credit score, it was 740, and his only credit event since has been applying for a store credit card. Which of these is most likely to be his credit score now?
According to the information, it can be inferred that the current credit score for Esteban is 730 because he has not used more transactions than eleven of his credit score.
What is the credit score?A credit score is a term that refers to an index that is intended to predict the chances that you will repay a loan on time.
This takes into account different factors related to your economy, so it is likely that the more movement of money you have, your score will be higher.
Based on the foregoing, it can be inferred that Esteban's score dropped because he has not made important transactions in recent months. Additionally, it has no recent transaction history.

Suppose a population of 250 fleas doubles in size every month. The function f(x)=250(2^x) gives the population after x months. How many fleas will there be after 1 year?
A. 500
B. 1,024,000
C. 6,000
D. 2,280
I'm not the best at math, but I tried.
x= the amount of months passed
The question asks for the population of fleas in 1 year, and 1 year = 12 months, then x would equal 12 months
Therefore, you substitute that x with 12
f(x)=250(2^x)-------f(x)=250(2^12)
Now you can solve that part of the problem:
2 to the power of 12= 4096
f(x)=250(4096)
now multiply that:
250×4096= 1024000
The answer is C. 1024000
The answer is 1,024,000 fleas.
The function f(x)=250(2^x) gives the population of fleas after x months. To find out how many fleas there will be after 1 year, substitute x=12 into the function:
f(12) = 250(2^12) = 250 * 4096 = 1,024,000 fleas.

3.4(x+1.58)=-11.288 value of x.
3.4(x+1.58)= - 11.288
Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)
3.4x + (3.4×1.58)= - 11.288
3.4x + 5.372 = -11.288
Step 2: Bring 5.372 to the right side by subtracting it to both sides
3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)
3.4x + (0) = (-16.66)
3.4x = -16.66
Step 3: Isolate x by dividing 3.4 to both sides
[tex]\frac{3.4x}{3.4} = \frac{-16.66}{3.4}[/tex]
x = -4.9

a quadradic polynomial has a degree of 2 true or false
Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
[tex]f(x)=ax^2+bx+c[/tex]
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.

One side of a rectangle is 6 yd longer than three times another side. The area of the rectangle is 72 yd2. Find the length of the longer side.
Answer:
18 yds
Step-by-step explanation:
Let the length and width be L and W respectively.
Then L· W = area = 72 yd², so that L = (72 yd²) / W.
But also L = 3W + 6 yd. Subbing this into L· W = area = 72 yd², we get:
(3W + 6) · W = 72, or
3W² + 6W - 72 = 0. Since all four terms are evenly divisible by 3, we get:
W² + 2W - 24 = 0, which factors as follows:
(W + 6)(W - 4) = 0. Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.
If the shorter side is of length 4 yds, then the longer side is of length
L = 3(4 yds) + 6 yds = 18 yds
Answer:
18 yd
Step-by-step explanation:
(3x + 6) * x = 72
Use the distributive property
3x^2 + 6x = 72
3x^2 + 6x - 72 = 0
3(x^2 + 2x - 24) = 0
X^2 + 2x - 24 = 0
X can equal -6 and 4.
4 only works for this problem
4 * 3 = 12
12 + 6 = 18
So, the answer is 18 yd.
Let’s check our work.
3 * 4 = 12
12 + 6 = 18
18 * 4 = 72
So, we know for a fact that the longer side is 18 yd long.

To ensure an excellent bond when brazing, the clearance gap between pipe and fitting must be _______ inches.
Step-by-step Answer:
Gap must be a maximum of 0.005 inches, and uniform all around. Round out with a sizing tool if necessary.
When brazing, the clearance gap between pipe and fitting should be between 0.002 and 0.006 inches.
This clearance gap is important to allow the brazing material to flow via capillary action and to create a strong, sealed joint. The exact clearance can vary depending on the materials and the application, but staying within this range is a good practice.
For brazing larger diameter pipes and fittings, a slightly larger gap may be acceptable, but generally it is best to maintain the smallest gap that will still allow for proper capillary action of the filler metal.
Which set of measures would give a clear conclusion about the data. Help please.
