Answer:
see step by step.
Step-by-step explanation:
The THEORETICALLY probability is 0.5000 (this is, 50% each one) since each one have equal chance of being in list A or List B, but this is still a random probability, so this is not the same that if you have 60 students, 30 of them are going to be in the list A and the other 30 in B.
The experimental result show:
\(P (ListA) = \frac{27}{60} =0.45\)
\(P (ListB) = \frac{33}{60} =0.55\)
This is 45% of being in list A and 55% of being in list B, notice these values are close the the experimental value (50%) but still are lightly higher or lower. Additionally notice if you add both of them you still have 100% (0.45+0.55=1.00)

3. (03.06) Choose the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2
Answers
Answer:
The answer is
\( \huge y + 3 = \frac{1}{2} (x - 6) \\ \)
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
\(y - y_1 = m(x - x_1)\)
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as
\(y + 3 = \frac{1}{2} (x - 6) \\ \)

Work out the volume of the prism height of 12 4 and five
Answers
The calculated volume of the prism is 702 cubic cm
Finding the volume of the prismFrom the question, we have the following parameters that can be used in our computation
The trapezoidal prism (see attachment)
The formula of the volume of a trapezoidal prism is
Volume = Base area * Height
Where we have
Base area = 1/2 * (8 + 10) * 6
Evaluate the sum of 8 and 10
Base area = 1/2 * 18 * 6
Evaluate the products of 1/2, 18 and 6
Base area = 54
Also, we have
Height = 13
So, the volume is calculated as
volume = 13 * 54
Evaluate
volume = 702
Hence, the volume of the prism is 702 cubic cm

What are angles?A point where two lines meet produces an angle.
The breadth of the "opening" between these two rays is referred to as a "angle". It is depicted by the figure.
Radians, a unit of circularity or rotation, and degrees are two common units used to describe angles.
By connecting two rays at their ends, one can make an angle in geometry. The sides or limbs of the angle are what are meant by these rays.
The limbs and the vertex are the two main parts of an angle.
The common terminal of the two beams is the shared vertex.

The altitude of an airplane is decreasing at a rate of 44 feet per second. What is the change in altitude of the airplane over a period of 34 seconds?
Answers
Answer:
1320 feet
Step-by-step explanation:
All we have to do is multiply the rate of change of altitude by the time it took the altitude to change.
The altitude of an airplane is decreasing at a rate of 44 feet per second. After 30 seconds, the change is altitude is:
44 * 30 = 1320 feet
The altitude of the airplane has changed by 1320 feet.
What is the equation of the line that passes through (-3,-1) and has a slope of 2/5? Put your answer in slope intercept form 1. Y=2/5x+1/52. Y=2/5x-1/53. Y= -2/5x-1/5
Answers
We are asked to determine the equation of a line that passes through the point (-3, -1) and has a slope 2/5. To do that we will use the point-slope form of a line equation:
\(y-y_0=m(x-x_0)\)Where:
\(\begin{gathered} (x_0,y_0)=\text{ point on the line} \\ m=\text{ slope} \end{gathered}\)Now, we plug in the values:
\(y-(-1)=\frac{2}{5}(x-(-3))\)Simplifying we get:
\(y+1=\frac{2}{5}(x+3)\)Now, we apply the distributive law:
\(y+1=\frac{2}{5}x+\frac{6}{5}\)Now, we subtract 1 from both sides:
\(\begin{gathered} y=\frac{2}{5}x+\frac{6}{5}-1 \\ \\ y=\frac{2}{5}x+\frac{1}{5} \end{gathered}\)and thus we get the equation of the line.

ABCD is a parallelogram.
The coordinates of point A are (2,5)
x = (4,0) and y = (5,12)
Find the coordinates of points B and C.
Answers
Answer:
B(6, 5), C(1, -7)
Step-by-step explanation:
A(2, 5)
From A to B, there is translation x, (4, 0).
Add 4 to A's x-coordinate, and add 0 to A's y-coordinate.
B(2 + 4, 5 + 0) = B(6, 5)
From C to B there is the translation y, (5, 12).
Since we are going from B to C, we undo translation y.
The translation from B to C is (-5, -12).
C(6 - 5, 5 - 12) = C(1, -7)

Answers
The correct answer is Select a row from the random number table. Count the number of zeros in the sample.
Random number table :A random number table is a table of digits that are arranged in a random order, typically between 0 and 9. It is used as a tool to generate random numbers for use in probability simulations, statistical analysis, and other applications.
In this case, the situation involves randomly selecting 20 students and counting the number of students who participate in sports, given that 10% of the students participate in sports.
Using the random number table to simulate one trial of this situation:
To simulate one trial of this situation using a random number table, the following steps can be followed:
Assign the digits to the outcomes as described in the problem:
0 = student participates in sports,
1-9 = student does not participate in sports.
Select a row from the random number table.
Read the first digit in the row and count it as one student in the sample. If the digit is 0, it means that the student participates in sports. If the digit is 1-9, it means that the student does not participate in sports.
Repeat step 3 for the next 19 digits in the row, counting each digit as one student in the sample.
Count the number of zeros in the sample. This represents the number of students who participate in sports in the sample.
By repeating this process multiple times, you can simulate multiple trials of this situation and calculate the probability of different outcomes, such as the probability of getting a certain number of students who participate in sports in the sample.
Hence,
The correct answer is Select a row from the random number table. Count the number of zeros in the sample.

If each person occupies 2.5 sq ft, what would the estimate be on one sides of the street in an rectangle of 2 yards wide and 15 yards deep?
Answers
Answer:
54 people
Step-by-step explanation:
If each person occupies 2.5 sq ft, what would the estimate be on one sides of the street in an rectangle of 2 yards wide and 15 yards deep?
1 yard = 3 feet
Width of the rectangle = 2 yards
2 yards to feet
= 2× 3 feet
= 6 feet
The Depth of the rectangle = 15 yards
= 15 yards to feet
= 15 × 3 feet
= 45 feet
Area of the rectangle = Width × Depth
= 45 feet × 6 feet
= 270 square feet
We are told in the question that:
If each person occupies 2.5 sq ft,
The would the estimate be on one sides of the street in an rectangle of 2 yards wide and 15 yards deep is calculated as:
2.5 sq ft = 1 person
270 square feet =
270 square feet/2.5 square feet
= 108 people for both sides of the street
But for one side of the street
= 108 people/2
= 54 people

Explanation:
This can be easily answered, but you can easily get it wrong if you don’t use PEMDAS.
PEMDAS is the order of operations when solving simple equations.
P - parentheses
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
We go down that list in order to figure out what we should solve first.
We have no parentheses, no exponents, BUT we have multiplication! Let’s do that first.
1.8 x 7 = 12.6
And now we can just solve for whatever is left over.
12.6 + 3 = 15.6
There’s our answer! 15.6
