What are the dimensions of the rectangular face of the
pyramid?
The dimensions of the rectangulas face are 3 feet by
Blank feet
Without additional information, it is not possible to determine the missing dimension of the rectangular face of the pyramid given only one dimension (3 feet).
Explanation:To find the missing dimension of the rectangular face of a pyramid when one dimension is given (3 feet), you generally need additional information about the pyramid such as the ratio of the dimensions, the area of the face, or an association with another geometric figure that reveals the missing dimension's value. Without this information, the second dimension remains undefined. As no such information is provided in the question or the provided context about various historical pyramids and their dimensions, it is not possible to accurately determine the 'blank' feet dimension of the pyramid's rectangular face.

A small school with 60 total students records how many of their students attend on each of the 180 days in a school year. the main number of students in attendance daily is 55 students and the standard deviation is 4 students. suppose we take a random sample of five School days and calculate the mean number of students in attendance on those days in each sample
Answer:
For the sampling distribution,
a) Mean = μₓ = 55.0 students.
b) Standard Deviation = 1.8 students.
Step-by-step explanation:
The complete Question is attached to this solution.
The Central limit theorem explains that for the sampling distribution, the mean is approximately equal to the population mean and the standard deviation of the sampling distribution is related to the population standard deviation through
σₓ = (σ/√n)
where σ = population standard deviation = 4
n = sample size = 5
Mean = population mean
μₓ = μ = 55 students.
Standard deviation
σₓ = (σ/√n) = (4/√5) = 1.789 students = 1.8 students to 1 d.p

Mrs. Smith gives the students in her geometry class the following conditional statement:
"If A, B, and C are collinear, then they lie on the same line."
Bob says that the inverse of the is statement is not true. What is the inverse of this statement? Is Bob correct?
Justify your answer.
Answer:
The inverse of the statement is, " If A, B, C are not collinear, then they do not lie on the same line." Bob is not correct. The inverse statement is true. For any points to be collinear, they have to be one the same line. If these points are not collinear, it means they do not lie on the same line.
Step-by-step explanation:
The inverse of the statement is "If A, B, and C do not lie on the same line, then they are not collinear," which is logically true based on the definition of collinear points. Bob's claim that the inverse is not true requires clarification; without it, he is incorrect.
Explanation:The inverse of the conditional statement "If A, B, and C are collinear, then they lie on the same line" is "If A, B, and C do not lie on the same line, then they are not collinear". When we discuss the inverse of a statement, we negate both the hypothesis and the conclusion of the original statement. In the given statement, collinear implies that the points lie on the same straight line. Hence, if they do not lie on the same line, logically they would not be collinear.
Bob's claim that the inverse of this statement is not true requires justification, as the truth of a statement's inverse is not necessarily linked to the truth of the original statement. However, in this particular case, the inverse does happen to be a logically true statement, because it is consistent with the definition of collinear points. If points don't lie on the same straight line, by definition, they cannot be collinear. So, if Bob is asserting that the inverse is always false without any context, Bob is incorrect.
It is important to note that this is a logical interpretation based on the definitions involved and is how geometric properties are understood. The truth of the inverse of the conditional is not dependent on the truth of the original statement but instead on the definitions of the terms used.

Step-by-step explanation:
if a number is divided by negative two, the solution is negative sixteen
-2/n= -16
n divided 2= -16
-2 n= -16
n/-2= -16
To solve for n when divided by negative two equals negative sixteen (n/-2 = -16), we multiply both sides by -2 to isolate n, yielding n = 32.
Explanation:To find the value of n, we need to follow the rule of signs for division which states that when a positive number is divided by a negative number, the result is negative (and vice-versa). So to solve n divided by negative two equals negative sixteen (n/-2 = -16), we need to multiply both sides of the equation by -2 to isolate n. The multiplication of -2 (a negative number) with -16 (also a negative number) will result in a positive outcome according to the multiplication rules for signs.
Step-by-step solution:
Start with the equation n/-2 = -16.Multiply both sides by -2 to get n = -16 × (-2).Calculating -16 multiplied by -2 according to rule number 6 gives us n = 32.Therefore, the value of n is 32.

a student asks you why it is possible to have an increase of 150% in price, but not a decrease of 150% in price. how would you answer the student?
Answer:
You can increase by 100% and more of the price in something but you can never decrease more than 100% of something.
Step-by-step explanation:
If you have something that costs 8 dollars to begin with then all of the sudden it costs 20 dollars, it increased by 150%. 8 is 100$ of 8, 4 is 50% of 8. 8+4=12. 12+8=20. The price began at 8 then increased by itself plus half of it which is 12.
IF you decrease the price by 150% it'll be -20 dollars. You cant physically have negative amount of money.

A boy has 380 prize tickets he wants to exchange for action figures at a prize booth. At
this prize booth 5 tickets can be exchanged for a large action ngure, and 7 tickets can be
exchanged for 2 small action Noures, The boy wants 4 times as many small action figures as
large action naures. Based on this information, can the boy get 80 small action figures?
F. No, because he would not have enough tickets for 20 large action figures
G Yes, because he would still have enough tickets for 320 large action figures
H No, because he would not have enough tickets for 320 large action figures
3
Yes, because he would still have enough tickets for 20 large action figures
Answer:
Step-by-step explanation:
Hi there,
If the boy wants 80 small action figures
that is equivalent to 40 x 7 (as 7 tickets
gives him 2 small action figures)
= 280 tickets.
The 380 tickets he has originally minus the
280 leaves 100 tickets to get 20 large action figures
(100/5)
He will have 80 small and 20 large action figures
80:20 = 4:1
Hope this helps:-)
Final answer:
Yes, the boy can exchange his 380 prize tickets for 80 small action figures and 20 large action figures, given the conversion rates and the desired ratio.
Explanation:
The student's question involves determining if a boy with 380 prize tickets can get 80 small action figures and still have enough tickets for 20 large action figures at a prize booth, given the exchange rates and the desire for 4 times as many small figures as large ones. To analyze this, we'll use the information that 5 tickets can be exchanged for a large action figure and 7 tickets can be exchanged for 2 small action figures. The boy wants 4 times as many small figures as large figures.
Let's denote large action figures as L and small action figures as S. According to the information given:
5 tickets = 1 large action figure (L)7 tickets = 2 small action figures (S), so 3.5 tickets = 1 small action figureTo have 4 times as many small figures as large, this means that if he gets x large figures, he needs 4x small figures. The total cost in tickets for the large figures would be 5x for the large and 14x for the small, totaling 19x tickets.
If he wants to get 80 small figures (S = 80), we would have 4x = 80 and thus x = 20 for large figures. So, the total ticket cost would be 19x which equals 19*20 = 380 tickets.
Therefore, the boy can get 80 small figures and 20 large figures with his 380 tickets. The correct answer is 'Yes, because he would still have enough tickets for 20 large action figures'.
How many solutions does this system have? 6 x + 3 y = negative 12. y = negative 2 x + 4. one , two , infinite number , no solution
Answer : no solution
Step-by-step explanation:
The system of the equations have infinitely many solutions.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
The linear equation of two variable is given below.
6x + 3y = –12
6x + 3y + 12 = 0 ...1
–2x + 4 = y
2x + y – 4 = 0 …2
The standard equations are given as
a₁x + b₁y + c₁ = 0
a₂x + b₂y + c₂ = 0
Compare equation 1 and 2 with the standard equation. Then we have
a₁ = 6, b₁ = 3, c₁ = 12
a₂ = 2, b₂ = 1, c₂ = –4
If the ratio of the coefficient of x and y are different, then unique solution.
If the ratio of the coefficient of x and y are same, but constant term ratio is different, then no solution.
If the ratio of the coefficient of x and y and constant term is same, then infinitely many solutions.
a₁ / a₂ = 6/2 = 3
b₁ / b₂ = 3/1= 3
c₁ / c₂ = 12/(-4) = -3
Then the condition will be
a₁ / a₂ = b₁ / b₂ ≠ c₁ / c₂
The system of the equations have infinitely many solutions.

The diameter of a semicircle is 2 yards. What is the semicircle's perimeter?
Use 3.14 for pie
The perimeter of a semicircle with a diameter of 2 yards is 5.14 yards when using 3.14 for pi.
Explanation:To calculate the perimeter of a semicircle with a diameter of 2 yards, we first need to find the radius, which is half of the diameter. Therefore, the radius (r) is 1 yard. Using the value of pi (π) as 3.14, the formula for the perimeter (P) of a semicircle is P = πr + 2r, where πr is the length of the semicircle's curved edge and 2r is the length of the diameter.
Plugging the radius into the formula, we get P = 3.14 × 1 yard + 2 × 1 yard. Simplifying this, we find P = 3.14 yards + 2 yards, which equals to 5.14 yards. Therefore, the perimeter of the semicircle is 5.14 yards.
Final answer:
The perimeter of a semicircle with a diameter of 2 yards is 5.14 yards, calculated by taking half the circumference of a full circle and adding the diameter.
Explanation:
To calculate the perimeter of a semicircle with a given diameter of 2 yards, we need to consider both the straight edge of the diameter and the curved edge of the semicircle.
The formula for the perimeter (P) of a full circle is P = πd, where π (pi) is approximately 3.14 and d is the diameter. Since we have a semicircle, we will take half of the circumference of the full circle and then add the diameter. So, the formula for the perimeter of the semicircle (P_semicircle) will be:
P_semicircle = (πd)/2 + d.
Let's plug in the values:
P_semicircle = (3.14 × 2 yards)/2 + 2 yards
P_semicircle = 3.14 yards + 2 yards
P_semicircle = 5.14 yards.
The perimeter of the semicircle is 5.14 yards.

What is Miguel’s expected value from playing the game?
Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays?
What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation.
Answer:
To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.
The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)
We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.
