Of 13 possible books, you plan to take 6 with you on vacation. How many different collections of 6 books can you take?
Answers
Taking into account the definition of combination, you can take 1716 different collections of 6 books.
CombinationCombinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in which the order in which the elements are chosen is not taken into account and repetition is not possible.
The combination is calculated by:
[tex]C=\frac{m!}{n!(m-n)!}[/tex]
The term "n!" is called the "factorial of n" and is the multiplication of all numbers from "n" to 1.
Collections of 6 books that you can takeIn this case it is possible to apply a combination, not all the elements enter, the order in which the books are chosen does not matter, and they are not repeated.
Being m= 13 and n=6, the combination is calculated by:

what is the unit rate
Answers
A unit rate (or unit ratio) describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. In our case the first type of quantity is blue parts and the second is white parts, so we should find how many blue parts correspond to one white part.
The ratio is: 5/4
We will obtain the unit ratio if we divide each number with 4 in order to get 1 - as a second quantity.
So, (5/4)/(4/4)= (5/4)/1
The unit ratio is:
(5/4)/1.
an architect designs a rectangular flower garden such that the width is exactly two thirds of the length if 320 ft of the antique picket fencing are to be used to enclose the garden find the dimensions of the garden
Answers
what's the width? well, w = (2/3)l.
The dimensions of the garden where 320 ft of the antique picket fencing are to be used to enclose the garden are 96 feet and 64 feet.
Given that:
A garden is in rectangular shape.
The length of the antique picket fencing used to enclose the garden is 320 feet.
The perimeter defines the enclosing length.
So, the perimeter is 320 feet.
Let P = 320.
Let l represent the length and w represents the width of the garden.
The width is exactly two-thirds of the length.
So, [tex]w=\frac{2}{3} l[/tex].
The perimeter of the garden is:
P = 2(l + w)
= 2 (l + [tex]\frac{2}{3} l[/tex])
= [tex]\frac{10}{3} l[/tex]
So, substitute P = 320.
[tex]\frac{10}{3} l=320[/tex]
Simplifying,
l = 96 feet
So, w = 64 feet
Hence, the dimensions are 96 feet and 64 feet.

A telephone survey uses a random digit dialing machine to call subjects. the random digit dialing machine is expected to reach a live person 15% of the time. in eight attempts, what is the probability of achieving exactly two successful calls?
Answers
We have
[tex]n=8[/tex]
[tex]r=2[/tex]
[tex]P(Success)=0.15[/tex]
[tex]P(Failure)=0.85[/tex]
Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
The probability of achieving exactly two successful calls in eight attempts in a telephone survey using a random digit dialing machine is approximately 0.324 or 32.4%.
Explanation:To calculate the probability of achieving exactly two successful calls in eight attempts in a telephone survey using a random digit dialing machine, we can use the binomial distribution formula. The formula is:
P(x) = (nCx) * (p^x) * ((1-p)^(n-x))
Where:
P(x) is the probability of getting exactly x successful callsn is the total number of attemptsx is the number of successful callsp is the probability of reaching a live personPlugging in the values from the question, we have:
P(2) = (8C2) * (0.15^2) * ((1-0.15)^(8-2)) = 28 * 0.0225 * 0.411771 = 0.3239965
Therefore, the probability of achieving exactly two successful calls in eight attempts is approximately 0.324 or 32.4%.

Average maintenance costs are $1.50 per machine-hour at an activity level of 8,000 machine-hours and $1.20 per machine-hour at an activity level of 13,000 machine-hours. assuming that this activity is within the relevant range, total expected maintenance cost for a budgeted activity level of 10,000 machine-hours would be closest to:
Answers
C = a + bx
where
x = machine hours
a, b are constants.
When x=8,000 hours, C=$1.50, therefore
a + 8000b = 1.5 (1)
When x=13,000 hours, C=$1.20, therefore
a + 13000b = 1.2 (2)
Subtract (2) from (1).
a + 8000b - (a + 13000b) = 1.5 - 1.2
-5000b = 0.3
b = -6 x 10⁻⁵
From (1), obtain
a = 1.5 - 8000*(-6 x 10⁻⁵) = 1.98
Therefore
C = 1.98 - 6x10⁻⁵ x
When machine hours is x=10,000, obtain

A single fair die is tossed. Find the probability of rolling a number greater than 4.
Answers
P(>4)=2/6
P(>4)=1/3
The probability of rolling a number greater than 4 with a single fair die is 1/3 or approximately 0.33. This is calculated as the number of desired outcomes (a roll of 5 or 6) divided by the total possible outcomes (1, 2, 3, 4, 5, or 6). The actual results of a short series of rolls may vary, but over time the results should average out to this probability.
Explanation:The question is asking to calculate the probability of rolling a die and getting a number greater than 4. In a fair six-sided die, the possible outcomes of a single toss are 1, 2, 3, 4, 5, or 6, making the total possible outcomes 6. The outcomes greater than 4 are 5 and 6, which gives us 2 desired outcomes.
Remember, probability is calculated as the number of desired outcomes over the number of total possible outcomes. So in this case, the probability is 2 (the number of outcomes greater than 4) divided by 6 (the total number of outcomes when rolling a die) which gives a probability of 1/3 or approximately 0.33.
This suggests that if you throw the single fair die repeatedly over time, about one third of the results would show a number greater than 4. It's essential to remember this is a theoretical probability, and actual short-term results may vary, but they should correspond to this probability in the long run per the law of large numbers.

Given p(a)=0.40, p(b)=0.50. if a and b are independent, what is the value of p(a intersection b)?
Answers
Final answer:
The value of P(A intersection B) is 0.20.
Explanation:
Given that events A and B are independent, the probability of their intersection can be found by multiplying their individual probabilities. So, P(A ∩ B) = P(A) * P(B). From the given information, P(A) = 0.40 and P(B) = 0.50. Therefore, P(A ∩ B) = 0.40 * 0.50 = 0.20.

If the beam cuts the water spray at points A and B, such that point B is at a higher level than point A, what distance from the ground level is point A?
Answers
well, we can get that off either equation, if we just know A coordinates, so let's see what "x" is at those A and B points.
[tex]\bf \begin{cases} y=-0.3x^2+3x\\ ----------\\ -2x+5.5y=19.5\\\\ y=\cfrac{19.5+2x}{5.5} \end{cases}\implies -0.3x^2+3x=\cfrac{19.5+2x}{5.5} \\\\\\ -1.65x^2+16.5x=19.5+2x\implies 0=1.65x^2-14.5x+19.5 \\\\\\ \textit{using the quadratic formula}\quad x=\cfrac{14.5\pm\sqrt{210.25-4(1.65)(19.5)}}{2(1.65)} \\\\\\ x\approx \begin{cases} 7.13\\ 1.66 \end{cases}\textit{ so those are A and B, who is who?, dunno, let's check}[/tex]
[tex]\bf y=-0.3x^2+3x\qquad x=7.13\qquad y=-0.3(7.13)^2+3(7.13) \\\\\\ y\approx 6.14\\\\ -------------------------------\\\\ y=-0.3x^2+3x\qquad x=1.66\qquad y=-0.3(1.66)^2+3(1.66) \\\\\\ y\approx 4.15[/tex]
so, as you can see, clearly 6.14 is higher, and thus is B.
thus A is 4.15, so the y-coordinate for point A is 4.15, and that's the distance from the beam hitting the fountain at A, to the ground.

Jack and Andrea want to create a right triangle together using values of x and y and the polynomial identity to generate Pythagorean triples. If Andrea picks a value of x = 2, and the hypotenuse of the resulting right triangle is 5, what natural number value of y did Jack pick? y = 1 y = 2 y = 3 y = 4
Answers
A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula:
c^2 = a^2 + b^2
or
c^2 = x^2 + y^2
where,
c is the hypotenuse of the triangle and is the side opposite to the 90° angle
while a and b are the sides adjacent to the 90° angle
In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y:
y^2 = c^2 – x^2
y^2 = 5^2 – 2^2
y^2 = 21
y = 4.58
The natural number is the number before the decimal. Therefore the answer is:
y = 4
