Of the people in Malik's apartment building, 4 like to eat macaroni and cheese, and 7 like to eat cookies.
Three people like to eat both macaroni and cheese and cookies.
To determine how many people like to eat macaroni and cheese or cookies or both, we will employ the principle of inclusion-exclusion.
In Malik's apartment building, to find out how many people like to eat macaroni and cheese, or cookies, or both, we can follow these steps:
Identify the number of people who like macaroni and cheese (4 people) and cookies (7 people).
Determine the number of people who like both macaroni and cheese and cookies (3 people).
Calculate the total number of people who like either macaroni and cheese or cookies by adding the number of people who like macaroni and cheese (4 people) and the number of people who like cookies (7 people).
4 people + 7 people = 11 people
Subtract the number of people who like both macaroni and cheese and cookies (3 people) from the total calculated in Step 3 to avoid double-counting those who like both.
11 people - 3 people = 8 people

A. 30 cm^3
B. 45 cm^3
C. 60 cm^3
D. 75 cm^3
the answer is 75 cm^3
The volume of the oblique prism is 75 cm³, which is option D.
Define Oblique prismAn oblique prism is a three-dimensional geometric shape that has two parallel and congruent bases that are connected by parallelogram-shaped lateral faces. Unlike a right prism, the lateral faces of an oblique prism are not perpendicular to the base faces.
The formula for the volume of an oblique prism is given by:
Volume = Base Area × Height
Since the base of the prism is a square, its area is given by:
Base Area = Side × Side = 5 × 5 = 25 square centimeters
Substituting this and the height given as 3 cm in the formula for the volume, we get:
Volume = Base Area × Height
= 25 × 3
= 75 cubic centimeters
Therefore, the volume of the oblique prism is 75 cm³, which is option D.

Step-by-step explanation:
A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. If the writer writes for one more day and comes up with 8 new comic strips, how will the skew be affected?
On the other hand, if the number of comic strips produced is similar to the other values in the dataset, it will have little effect on the overall skew.
What is Algebraic expression ?
An algebraic expression is a mathematical phrase that can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions are used to represent and solve problems in many areas of mathematics, science, engineering, and finance.
The skew of a dataset refers to the degree to which the distribution of values is asymmetrical. A dataset is said to be skewed if the majority of the values lie on one side of the mean.
In this case, the dataset has a right skew because there are more values on the right side of the distribution (higher values) than on the left side. We can see this by noting that the median (middle value) is 3, while the mean (average value) is slightly higher at 3.375.
If the writer writes 8 more comic strips on the next day, it will increase the maximum value in the dataset from 7 to 8. This will slightly shift the distribution to the right, but the skew will remain right because the majority of the values are still clustered on the right side of the distribution.
However, the effect on the overall skew will depend on the number of comic strips the writer produces on the next day relative to the other values in the dataset. If the writer produces a large number of comic strips relative to the other values, it could shift the distribution to a more symmetrical shape.
Therefore, On the other hand, if the number of comic strips produced is similar to the other values in the dataset, it will have little effect on the overall skew.

You want to buy some noodles. A 6-ounce package costs $1.98. A 14-ounce package costs $4.90. A 22-ounce package costs $7.04. Which package is the best buy?
Answer:
22-ounce package is the best buy as it has the lowest price per ounce.
Step-by-step explanation:
To determine which package is the best buy, we need to calculate the price per ounce of each package:
Price per ounce of 6-ounce package = 1.98 / 6 = $0.33 per ounce
Price per ounce of 14-ounce package = 4.90 / 14 = $0.35 per ounce
Price per ounce of 22-ounce package = 7.04 / 22 = $0.32 per ounce
Therefore, the 22-ounce package is the best buy as it has the lowest price per ounce.
a computer password consists of nine characters. replications are allowed. how many different passwords are possible if each character may be any lowercase letter or digit? enter your answer in scientific notation with two digit of accuracy after the decimal point.
To calculate the number of possible passwords, we need to find the total number of combinations of lowercase letters and digits for each character of the password.
Then raise that number to the power of 9 (since there are 9 characters in the password and replications are allowed). There are 26 lowercase letters and 10 digits (0 to 9), so the total number of options for each character is 26+10=36.
Therefore, the number of possible passwords is[tex]36^9[/tex], which is equal to 1.0333862 ×[tex]10^16[/tex] (rounded to two decimal places in scientific notation). In other words, there are over 10 quadrillion possible combinations of passwords, making it very difficult for someone to guess or hack into the system by trying different combinations.

Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.
what is sequence ?An structured of integers or objects that adhere to a particular pattern or rule is referred to as a sequence in mathematics. The name for each number or item in the sequence is. A series can be explicitly created or defined recursively, and it can be infinite or finite. A method or rule that directly expresses the n - th term of the series in terms of n defines an explicit sequence. For instance, the explicit sequence 2, 4, 6, 8, 10,... has the formula a = 2n, where n is the term's position inside the sequence. A starting value and recursive formula that determines the nth word of the series in terms of the preceding terms describe a recursive sequence.
given
The number sequence is as follows: 64, -128, 256, -512.
We must determine the common ratio between the following terms in order to get the rule for this sequence.
Any term can be divided by its previous term to obtain the common ratio (r). For instance, the result of subtracting the second term (-128) from the first term (64) is
r = (-128) / 64 = -2
The third term (256) divided by the second term (-128) results in:
r = 256 / (-128) = -2
And when the fourth term (-512) is divided by the third term (256), the result is
r = (-512) / 256 = -2
We can observe that for all pairings of following terms, the common ratio is -2.
Now we can apply the following formula to a geometric sequence's general term:
a = a1 * r^(n-1) (n-1)
where r is the common ratio and a1 is the first term.
In place of the values we hold:
[tex]a = 64 * (-2)^(n-1) (n-1)[/tex]
Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.

a smartphone was purposefully dropped from a height of 10 meters to test its durability from external physical impact. it will be damaged 100% of the time, but the damage can occur in different parts of the phone. it has been shown that 76% of the damages occur in the glass screen, while the other 24% occur in the battery. a number of smartphones were tested and the tests were independent. find the probability that the first time you observe a battery damage is during the third trial or later.
Answer:
what the quistion?
Step-by-step explanation:
sry i cant spell
The probability that the first time a battery damage is observed is during the third trial or later is 42.74%.
To solve this problem, we can use the geometric distribution, which models the number of trials until the first success in a sequence of independent trials. In this case, the probability of success is 0.24 (the probability of a battery damage) and the probability of failure is 0.76 (the probability of a glass screen damage).
The probability of observing a battery damage for the first time on the third trial or later can be calculated as the complement of the probability of observing a battery damage on the first or second trial.
The probability of observing a battery damage on the first trial is 0.24, and the probability of observing a battery damage on the second trial is (0.76)(0.24) = 0.1824 (the probability of no battery damage on the first trial times the probability of battery damage on the second trial). Therefore, the probability of observing a battery damage for the first time on the third trial or later is 1 - 0.24 - 0.1824 = 0.5776.
However, the question asks for the probability of observing a battery damage for the first time on the third trial or later, which means we need to take into account the fact that we may have observed a battery damage before the third trial. Therefore, we need to adjust our calculation by subtracting the probability of observing a battery damage for the first time on the first or second trial from our previous result.
The probability of observing a battery damage for the first time on the first or second trial is 0.24 + 0.1824 = 0.4224. Therefore, the probability of observing a battery damage for the first time on the third trial or later is 0.5776 - 0.4224 = 0.1552 or 15.52%.
Therefore, the probability that the first time a battery damage is observed is during the third trial or later is 42.74%

Explain why all of these statements are false: (a) The complete solution to Ax = b is any linear combination of Xp and Xn. (b) The system Ax- b has at most one particular solution. (c) If A is invertible, there is no solution Xn in the nullspace.
These statements are false because (a)False because the complete solution to Ax = b is actually the sum of the particular solution Xp and any linear combination of the solutions in the nullspace Xn. (b) False because if the system Ax = b has a particular solution, it will always have exactly one particular solution. (c) False because if A is invertible, there is indeed a solution Xn in the nullspace, but it is only the trivial solution Xn = 0.
(a) The complete solution to Ax = b is any linear combination of Xp and Xn is false.
Mathematically, the complete solution is given by X = Xp + Xn, not just any linear combination of Xp and Xn.
(b) The system Ax = b has at most one particular solution.
This is due to the fact that the particular solution is the unique point where the affine subspace defined by the system intersects the null space of A.
(c) If A is invertible, there is no solution Xn in the null space.
An invertible matrix has a unique solution for each b, which implies that the null space only contains the zero vector.

you have a 13 oz. bottle and a 20 oz. bottle, with which you wish to measure exactly 2 oz. however, you have a limited supply of water. if any water enters either bottle and then gets dumped out, it is gone forever. what is the least amount of water you can start with and still complete the task?
The least amount of water required to measure exactly 2 oz is 12 oz. (13 oz + 7 oz - 8 oz = 12 oz).
First, add 13 oz of water to the 20 oz bottle. The combined amount of water will now be 33 oz.
Next, pour water from the 33 oz bottle into the 13 oz bottle until the 13 oz bottle is full to the top.
The remaining amount of water in the 33 oz bottle will be 20 oz.
Now, pour out the water in the 13 oz bottle into the 20 oz bottle.
Now, the 20 oz bottle will have 13 oz of water in it. This leaves the 33 oz bottle with 7 oz of water remaining in it.
Now, pour the remaining 7 oz of water in the 33 oz bottle into the 20 oz bottle.
The 20 oz bottle will now have 20 oz + 7 oz = 27 oz of water in it.
Pour out the water in the 20 oz bottle until the amount of water in it is exactly 2 oz.
Since you started with a combined amount of 33 oz, and the amount of water remaining in the 20 oz bottle is 2 oz, the
amount of water poured out is 33 oz - 2 oz = 31 oz.
Therefore, the least amount of water required to measure exactly 2 oz is 12 oz.

The 69.15% of the corks produced by the machine are acceptable. 80% of all corks produced by the machine have diameters less than 3.0772cm.
a) To find the percentage of acceptable corks, we have to calculate the area under the normal distribution curve corks have diameters between the limits of 2.95 cm and 3.05 cm.
Let X be the diameter of the corks produced by the machine. Then X follows a
The corks with diameters that have a normal distribution with mean μ = 3.01 cm
Standard deviation σ = 0.08cm.
Using the standard normal distribution, we can standardize X as follows:
Z = (X - μ) / σ
= (X - 3.01) / 0.08
The probability that Z lies between (2.95 - 3.01) / 0.08 = - 0.75
The probability that Z lies between(3.05 - 3.01) / 0.08 = 0.50.
Using a standard normal table that this probability is approximately 0.6915.
Therefore, the percentage of acceptable corks produced by the machine is 69.15%.
b) To find the diameter D such that 80% of the corks produced by the machine have diameters less than D.
Using the standard normal distribution the Z-score that corresponds to the 80th percentile is:
Z = InvNorm(0.8)

A triangle has sides with lengths 8, 15, and 17.
Is this a Pythagorean Triple? (yes/no)
With a ratio comparing 8/15, that acute angle should measure between and degrees but closer to degrees.
Answer:
Yes, the triangle with sides 8, 15, and 17 is a Pythagorean triple. This is because 8^2 + 15^2 = 64 + 225 = 289 = 17^2. As for the acute angle between sides 8 and 15, we can use the inverse tangent function to find it. tan(theta) = 8/15 theta = arctan(8/15) Using a calculator, we find that theta ≈ 28.07 degrees. Since we know this is an acute angle, we can conclude that it measures between 0 and 90 degrees, and is closer to 28 degrees than to 62 degrees.

There is a statue that is 12 feet tall. When the sun is really low, it casts a shadow on the ground that is 20 feet long. What is the distance from the top of the statue to the top of the shadow?
Answer
sqrt 544 feet
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
12^2 + 20^2= c^2
144+400=c^2
544=c^2
c= sqrt 544
What number is closest to the root number 120

- A fisherman is measuring the amount of bait he has remaining, y, in his bucket. He puts 20 pieces of bait in his bucket at the beginning of his fishing trip and uses 2 pieces every hour, x.
What is the slope for this linear relationship, and what does it mean in this situation?
A) −2; the amount of bait decreases by 2 pieces each hour
B) 2; the amount of bait increases by 2 pieces each hour
C) −20; the amount of bait in the bucket when the fishing trip began
D) 20; the amount of bait in the bucket when the fishing trip began
From the given situation of fisherman , linear relationship is given by y= 2x + 20 the slope for the linear relationship is defined by 2 as amount of bait increases by each hour by 2 pieces.
What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
From the given situation of fisherman , linear relationship is given by
y= 2x +20 the slope for the linear relationship is defined by 2 as amount of bait increases by each hour by 2 pieces.
As given in the question,
Number of baits in the bucket of fisherman at the beginning of trip = 20
Amount of bait increases by 2 pieces every hour
Linear relationship is defined as :
'y' represent the total number of bait in the bucket after x hours.
y = 20 + 2x
Compare it with the general equation y =mx + c
Where 'm' is the slope.
Here slope is equal to 2.
According to the situation it means the amount of bait increases by 2 pieces in every hour.
Therefore, From the given situation of fisherman , linear relationship is given by y= 2x + 20 the slope for the linear relationship is defined by 2 as amount of bait increases by each hour by 2 pieces.

What is the length of the line that has the coordinate pairs of (-4 1/2,5) and (8 2/3, 5) ?
The length of the line that has the coordinate pairs of (-4 1/2,5) and (8 2/3, 5) is 12.16 units.
What are distance formulae?If two points of coordinates are given then we calculate the distance between them by using the following formulae
To find the length of the line is nothing but the calculation of the distance between two points that are given in the question.
[tex]d = \sqrt{(x_{2} - x_{2} )^{2} +(y_{2} - y_{1} )^{2} }[/tex]
d is the distance between two points.
(x1, x2) and (y2, y1) are the two endpoints of the line.
We can put all the values into the distance formulae and find the length of the line segment.
x1 = -4 1/2 = -3.5, y1 = 5
x2 = 26/3 = 8.6667, y2 = 5
[tex]d = \sqrt{(8.6667-(-3.5))^{2} +(5 - 5)^{2}\\[/tex]
= 12.16
Therefore, the length of the line segment is approximately 12.16 units.
