An arts academy requires there to be 6 teachers for every 96 students and 3 tutors for every 30 students. How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 100 students?
If the school requieres 6 teachers for every 96 students then
1 teacher will be required for every
= 96/6
= 16 students
If 3 tutors for every 30 students then 1 tutor is required for
= 30/3
= 10 students
If the academy has 100 students, the number of tutors required would be
= 100/10
= 10 tutors
Hence
The academy requires;
Find the maximum and minimum values of the objective function f(x, y) and for what values of x and y they occur, subject to the given constraints.
f(x, y) = 2x + 6y
x ≥ 0
y ≥ 0
2x + 7y ≤ 70
8x + 4y ≤ 136
Given that f(x, y) is a linear function, and the constraints themselves are also linear, it follows that the vertices of the feasible region are the sites of extrema of f(x, y). So just find where each boundary line intersects with another line, and check the value of f(x, y) at each intersection.
We have
• x = 0 and y = 0 ===> (0, 0)
• x = 0 and 2x + 7y = 70 ===> y = 10 ===> (0, 10)
• y = 0 and 8x + 4y = 136 ===> x = 17 ===> (17, 0)
• 2x + 7y = 70 and 8x + 4y = 136 ===> (14, 6)
At these points, we respectively get
• f (0, 0) = 0
• f (0, 10) = 60
• f (17, 0) = 34
• f (14, 6) = 64
Then max f(x) = 64 at (14, 6) and min f(x) = 0 at (0, 0).

Instructions: Identify the type of sequence and write the explicit rule. write Explicit Rule Sequence: -39, -45, 51, 57,... Type: Arithmetic e Explicit Rule:
The given sequence does not follow a simple arithmetic or geometric pattern, making it challenging to determine an explicit rule based on the given terms.
To identify the type of sequence and write the explicit rule, we need to examine the pattern of the given sequence: -39, -45, 51, 57, ...
By observing the differences between consecutive terms, we can determine if it follows an arithmetic or geometric pattern.
Arithmetic sequences have a common difference between each term, meaning that by adding (or subtracting) the same value repeatedly, we can generate the sequence. Geometric sequences, on the other hand, have a common ratio between each term, meaning that by multiplying (or dividing) by the same value repeatedly, we can generate the sequence.
Let's calculate the differences between consecutive terms:
-45 - (-39) = -6
51 - (-45) = 96
57 - 51 = 6
From the differences, we can see that the sequence is not arithmetic since the differences are not constant. However, the differences alternate between -6 and 6, indicating a possible geometric pattern.
Let's calculate the ratios between consecutive terms:
-45 / (-39) ≈ 1.1538
51 / (-45) ≈ -1.1333
57 / 51 ≈ 1.1176
The ratios are not constant, indicating that the sequence is neither geometric nor arithmetic.
Therefore, the given sequence does not follow a simple arithmetic or geometric pattern, and it is difficult to determine the explicit rule based on the given terms. It is possible that the sequence follows a more complex pattern or rule that is not apparent from the given terms.

esearchers believed that an increase in lean body mass is associated with an increase in maximal oxygen uptake. A scatterplot of the measurements taken from 18 randomly selected college athletes displayed a strong positive linear relationship between the two variables. A significance test for the null hypothesis that the slope of the regression line is 0 versus the alternative that the slope is greater than 0 yielded a p-value of 0.04.
Which statement is an appropriate conclusion for the test?
(A)The p-value of 0.04 indicates that 4% ofthe variation in maximal oxygen uptake for college athletes can be explained by the amount of lean body mass.
(B) The p-value of0.04 indicates that 16% of the variation in maximal oxygen uptake for college athletes can be explained by the amount of lean body mass.
(C)The strong positive linear relationship displayed in the scatterplot along with a p-value less than 0.05 indicates that college athletes with higher lean body mass tend to have higher maximal oxygen uptake.
(D)The strong positive linear relationship displayed in the scatterplot along with a p-value less than 0.05 indicates that an increase in lean body mass causes an increase in maximal oxygen uptake for college athletes.
(E) A p-value less than 0.05 indicates that the relationship displayed in the scatterplot is likely due to chance, and that there is no statistical evidence ofa relationship between lean body mass and maximal oxygen uptake for college athletes.
Answer:
The correct option is (D).
Step-by-step explanation:
The p-value is well defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was truly observed.
A small p-value (typically ≤ 0.05) specifies solid proof against the null hypothesis (H₀), so you discard H₀.
A large p-value (> 0.05) specifies fragile proof against the H₀, so you fail to discard H₀.
The hypothesis is defined as follows:
H₀: The slope of the regression line is 0, i.e. β = 0.
Hₐ: The slope of the regression line is greater than 0, i.e. β > 0.
A scatter-plot of the measurements taken from 18 randomly selected college athletes displayed a strong positive linear relationship between the two variables; lean body mass and maximal oxygen uptake.
The significance level of the test is, α = 0.05.
The p-value of the test is, p-value = 0.04
As the p-value = 0.04 < α = 0.05, we reject the null hypothesis.
So, it can be concluded that there is a statistical evidence of a relationship between lean body mass and maximal oxygen uptake for college athletes.
Since the scatter-plot shows a strong positive linear relationship, it implies that as the an increase in lean body mass causes an increase in maximal oxygen uptake for college athletes.
Thus, the correct option is (D).
Which of these are overlapping events?Drawing a Queen of Hearts or a Jack of Spades from a standard deck of cards
Drawing a face card or a 9 from a standard deck of cards
Drawing a Diamond or a Club from a standard deck of cards
Drawing a red card or a Queen from a standard deck of cards
Therefore , the solution of the given problem of probability comes out to be the right response is thus: "Drawing a red card or a Queen from a regular deck of cards is an overlapping occurrence."
What precisely is involved in the chance procedure?The primary objective of statistical inference, a branch of mathematics, is to determine the chance that a claim is true or that a specific event will occur. Chance can be represented by any number between 0 and 1, in which 1 typically represents certainty and 0 typically represents possibility. A probability diagram shows the chance that a specific event will occur.
Here,
Because the Queen of Hearts and Jack of Spades are not face cards or nines,
the occurrences "Drawing a Queen of Hearts or Jack of Spades from a standard deck of cards" and "Drawing a face card or a 9 from the a standard deck of cards" do not overlap.
A Queen of Hearts is both a red card and a queen, and a diamond is a type of red card and a club is a type of card, so the occurrences "Drawing a Diamond or a Club from a Standard Deck of Cards" and "Drawing a Red Card or a Queen from a Standard Deck of Cards" overlap.
The right response is thus: "Drawing a red card or a Queen from a regular deck of cards is an overlapping occurrence."

Find the distance between the point (7,6) and the line y=2x-1
The distance between a line with the equation ax + by + c = 0 and a point (A, B) is given by the formula:
\(\frac{|aA+bB+c|}{\sqrt[]{a^2+b^2}}\)So, before we can apply this formula, let's rewrite the equation of the line in the form ax + by + c = 0:
y = 2x - 1
2x - 1 = y
2x - 1 - y = y - y
2x - y - 1 = 0
So, in this case, we have:
a = 2
b = -1
c = -1
Also, since we want to find the distance between this line and the point (7, 6), we have:
A = 7
B = 6
Using those in the formula, we find the distance:
\(\frac{|aA+bB+c|}{\sqrt[]{a^2+b^2}}=\frac{|2\cdot7-1\cdot6-1|}{\sqrt[]{2^2+(-1)^2^{}}}=\frac{|14-6-1|}{\sqrt[]{4+1}}=\frac{|7|}{\sqrt[]{5}}=\frac{7}{\sqrt[]{5}}\)Therefore, that distance is

Which statement is true about the points shown on the number line?
Option B is a correct representation of the given number line, -3.8 < 1.5, and is located to the left of 1.5.
What is a number line?A number line is a visual depiction of numbers on a straight line drawn either horizontally or vertically. It is simple for humans to compare numbers and carry out simple arithmetic operations on them when they are written down on a number line. A number line is thought to begin at zero (0). Left of zero, there are only negative numbers, and right of zero, there are only positive numbers.
Given a number line and two points marked on it,
-3.8 and 1.5
we find from the number line that -3.8 lie left to 1.5,
and the negative numbers are always less than the positive numbers,
so -3.8 is less than 1.5,
-3.8 < 1.5, and lie left to 1.5.
Hence, option B is correct.
