Answer:
The correct answer is A,G,E
Final answer:
The center is closer to 14, the peak is at 14, the plot is skewed to the left, the spread is from 10 to 15, and the person waited for the bus 16 times which indicate the number of dots or data entries on the dot plot.
Explanation:
From the provided description, we can make several determinations about the dot plot. The center would represent the typical or median value. Because the data is divided in such a way that 11 is to the left and 14, we can observe that the center is somewhat closer to 14 than it is to 13. Therefore, the accurate statement would be that 'The center is 14' rather than 'The center is 13.'
The peak of the dot plot is the value with the greatest frequency, which is the number that has most dots associated with it. As mentioned in the question, 14 has 6 dots, which is the highest count, so it's accurate to say that 'The peak is at 14.'
The plot doesn’t have two even groups of data, hence the statement 'It has two clusters' is incorrect. Also, since the majority of the data points or dots are towards the right-hand side, it's more accurate to say that this plot is skewed left. The spread of the data is actually from 10 to 15, not from 13 to 15. Lastly, by counting the total number of dots which represent the number of days, it is accurate to say 'The person waited for the bus 16 times'.

It takes 10 workers 5 days to complete a road repair when working 2 hours a day.
So, this becomes : man hours required to finish the work.
Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d
So, total man hours =
Now, or
Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.
It will take 10 days for 2 people working 5 hours a day to finish the road repair.
Further Explanation:
From the question;
10 workers can finish road repair in 5 days working 2 hours a day
We need to find;
The number of days required to complete the road repair by 2 workers working 5 hours a day.
Assuming the number of days required to complete the work is x
Number of working hours of 10 people is 10 hours ( 2 hours a day for 5 days)
Number of working hours of 2 people is 5x hours (5 hours a day for x days)
Note that; the number of workers or people is inversely related to the number of working hours.
Therefore;
Product of number of people and working hours or work done is a constant
Thus;
10 × 10 = 2 × 5x
100 = 10 x
x = 10
Therefore;
2 workers working 5 hours a day will require 10 days to complete the road repair.

OK. You asked for it. Here we go.
First, let's gather up the tools we might use ...
some things that we know about triangles:
-- Every triangle: Area = (1/2) x (length of the base) x (the height)
-- Isosceles triangle: It has two sides that are the same length.
-- Right triangle: It has one right angle in it.
The sides that meet at the right angle are called the "legs".
They form a corner there, like this _| .
-------------------------------------------
Now we can start using these tools to hack away at the problem.
Farmer Ted has an isosceles right triangle garden.
The problem asks us to figure out how long the legs are.
Before he changes anything, it looks like this _| and both of
those sides are the same length. Call it 'x' until we figure out
what it really is.
Notice that one of them is the base of the triangle, and the other one
is the height. So the area of this triangle is
(1/2) (x) (x) or (1/2) x² .
-------------------------------
Farmer Ted is never satisfied. Suddenly, one day without warning, he
comes along and makes the garden bigger. He makes one of the legs
7 ft longer, and he makes the other one 5 ft longer.
Now the length of one leg is (x + 7) and the other one is (x + 5) .
They're still the base and height of the triangle, so the area of the
bigger garden is
(1/2) (x + 7) (x + 5).
The problem says that this area is 55 square feet more than the original
area, so look out, here comes the equation :
new area = old area + bigger
(1/2) (x + 7) (x + 5) = (1/2) x² + 55
Locked in the mysterious shadowy crevices of this equation is
everything we need in order to figure out the original length of the legs ...
what we called 'x'.
At this point, we can forget about Farmer Ted, forget about the garden,
and just go back to our laboratory with this equation and solve it to find 'x'.
Let's take it slow and easy, one little step at a time:
(1/2) (x + 7) (x + 5) = (1/2) x² + 55
Multiply each side by 2 : (x + 7) (x + 5) = x² + 110
Expand (FOIL) the left side: x² + 12x + 35 = x² + 110
Subtract x² from each side: 12x + 35 = 110
Subtract 35 from each side: 12x = 75
Divide each side by 12 : x = 6.25 feet
==============================================
OK. That's a very nice number. How do we know whether it's correct ?
Let's check it out, and see if it fits the story:
Original area = (1/2 x base x height) = (0.5 x 6.25 x 6.25) = 19.53125 sq ft
One new leg = (6.25 + 7) = 13.25 ft
Other new leg = (6.25 + 5) = 11.25 ft
New area = (1/2 x base x height) = (0.5 x 13.25 x 11.25) = 74.53125 sq ft
How much bigger is the new area ?
74.53125 - 19.53125 = 55 sq ft yay !
When we start with legs that are 6.25-ft and go through the whole story,
the new area is exactly what the problem says it was. So 6.25-ft is the
correct original length of the legs, before Farmer Ted messed with it.
