Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does
this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes
that the observed frequency of pulling a blue pen will eventually be closer to the expected
frequency based on the theoretical probability of pulling a blue pen. Which reasoning best
supports his conclusion?
Answer:
The more experiments that are done, the more the theoretical trend is marked
Step-by-step explanation:
The first thing is to define each probability,
-Theoretical probability is a proportion that expresses the ways to be successful in the total events of an experiment.
-Experimental probability is the proportion of the proposed result for the number of experimental attempts.
Based on this, the reason that best supports this is that the more the experiment is repeated, the closer the experimental probability gets to the theoretical one, since as the number of attempts increases, it tends to go more to what theoretically is what would happen.

There are 24 students in the class. If 12 of them enrolled to the French courses, 13 of them to the Spanish and 7 of them take neither, what is the probability that a randomly-chosen student from this group is taking only the French class?
Answer:
1/6 = 0.1667 = 16.67%
Step-by-step explanation:
If there are 24 students in the class and 7 of them take neither courses, we have 17 students that take one or both courses.
To find the students that took both courses, we can use the formula:
N(Spanish or French) = N(Spanish) + N(French) - N(Spanish and French)
17 = 13 + 12 - N(Spanish and French)
N(Spanish and French) = 8
Then, the number of students that are taking only French is:
N(only French) = N(French) - N(Spanish and French)
N(only French) = 12 - 8 = 4
So the probability of chosing a student that took only French is:
P(only French) = N(only French) / N(total)
P(only French) = 4 / 24 = 1/6
The Bilbo Company plans to manufacture decals for children's lunchboxes. Each decal
would cover one rectangular side of a lunchbox, as shown in the figure above. Which of
the following expressions gives the area, in square inches, of the decal, in terms of a and
Answer: 1 -2ax²+2x-ax
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: length x width
Replacing with the values given:
A = (2x+1) (1-ax)
A = [2x(1)] + [2x(-ax)] +[ 1(1)]+ [1 (-ax)]
A = 2x- 2ax² +1- ax
A = 1 -2ax²+2x-ax
In conclusion, the correct option is 1 -2ax²+2x-ax

7. The largest of the Great Pyramids in Egypt was built with a square base,
having edges that measured 754 feet and a height of 481 feet. Today, after
years of erosion, the base edges are 745 feet and its height is 471 feet. To the
nearest cubic foot, find the difference between the original and current
volumes of the pyramids.
Please show work
Answer:
Difference between the original and current volumes = 4013140.30 cubic feet
Step-by-step explanation:
Largest pyramid has the square base with one edge = 754 feet
Area of the square base = (Side)²
= (754)²
= 568516 square feet
Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Height})[/tex]
= [tex]\frac{1}{3}\times 568516\times 481[/tex]
= 91152065.3 cubic feet
After erosion,
Area of the base = (745)² = 555025 square feet
Volume of the pyramid = [tex]\frac{1}{3}(555025)(471)[/tex]
= 87138925 cubic feet
Difference between the original and current volumes of the pyramid
= 91152065.30 - 87138925
= 4013140.30 cubic feet
Peter buys a house that costs $100,000. If the
house loses 5% of its value each year, to the
nearest dollar, what will be the value of the
house after 6 years?
(A) $63,025
(B) $66,342
(C) $69,834
(D) $73,509
(E) $77,378
Answer:
None of these, it's $70,000.
Step-by-step explanation:
5% of $100,000 is $5,000
$5,000 · 6 (# of years) = $30,000
$100,000 - $30,000 = $70,000
James wants to build a wooden planter box for his garden with a volume of 100 cubic feet. If he constructed the planter with a height of 2 feet and a width of 5 feet, what should the length of the planter be, in feet?
Answer:
The length of the box is 10 feet.
Step-by-step explanation:
You have to work backwards to find volume, so just divide the volume (100) by the height (2) then divide that by the width (5) and you get your answer, 10

What is the slope of a line PARALLEL to the graph?
es
A)-3
B)0
C)3
D)-1/3
Answer:
C) 3
explanation:
parallel lines never touch, they are the same slope with different y-intercepts.
Right here the slope is 3, which means the slope is going to be 3
As a rule, parallel lines will always have the same slope.
The || symbol represents "parallel".
So if the slope of a line is parallel to this graph, the line
must have a slope of 3 since this line has a slope of 3.
As a quick review, remember that slope describes how steep a line is.
It can be found using the ratio rise/run between
any two points that are on that line.

A circular field is set into a square with an 800 m side length. Estimate the field's area.
A square where the vertical distance is labeled 800 meters.
About 5,000 m2
About 50,000 m2
About 500,000 m2
About 5,000,000 m2
About 50,000,000 m2
Answer:
c = 500,000
This is 6 digit number with 5 zero's.
We just multiply the radius ^2 by pi
D = 800m R = 400
R^2 = 400 x 400 = 160000
A = 160000π = 502654.824574
We estimate from 160000 and just count the 0's on multiplication as long as the 10's don't change in that estimation.
we can show the workings as the counting loops under the 6 and 0's of 160000. = 5 units+ 1.
= 500,000 m^2
1 [- - - - -} = 500000

Find the surface area of the regular pyramid. Write your answer as a decimal. (solved)
Answer:
The total surface area is 145.12 sq.m.
Step-by-step explanation:
We are supposed to find the surface area of given figure
Length of rectangular part = 15 m
Breadth of rectangular part = 8 m
Area of rectangular part =[tex]Length \times Breadth = 15 \times 8 = 120 sq.m.[/tex]
Diameter of semi circle = 8 m
Radius of semicircle = [tex]\frac{8}{2}=4 m[/tex]
Area of semicircle = [tex]\frac{\pi r^2 }{2}=\frac{3.14 \times 4^2}{2}=25.12 sq.m.[/tex]
Total surface area = 120+25.12=145.12 sq.m.
Hence The total surface area is 145.12 sq.m.

Please answer correctly my grade depends on it
Answer:
The answer is B.
Step-by-step explanation:
Since they all have a common denominator, you can group the numerators together. Therefore, we have...
[tex]\frac{(9x-5)+(3x-8)-(5x+3)}{4x-1}[/tex]
Now, we simply need to simplify.
[tex]=\frac{9x-5+3x-8-5x-3}{4x-1} =\frac{7x-16}{4x-1}[/tex]
This cannot be simplified further.
