Find the probability. If 81% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separate flights will all take place
Answers
The probability that 3 separate flights will all take place is 0.531441
let A = event of scheduled flight actually take place
According to the question, P(A)=0.81
Given that 3 separate flights will all take place is an independent event.
Hence, we can use the multiplicative rule which says If the probability that one given flight takes place is 0.81 then the probability of 3 flights taking place is:
P(A∩B∩C) = P(A)*P(B)*P(C)
= 0.81*0.81*0.81
= 0.531441
so, the Probability that 3 separate flights will take place is 0.531441

Given the following rectangle and circle, what appropriate value of x are the two areas equal? A: x= 3.4 B: x=5.8 C: x= 10.2 D: the curves do not intersect, so there is no solution
Answers
The correct option is D:
the curves do not intersect, so there is no solution
For what values of x are the two areas equal?
The area of the rectangle is given by:
f(x) = (x + 7)*(5x - 3)
f(x) = 5x² -3x + 35x - 21
f(x) = 5x² + 32x - 21
For the circle, the area is:
g(x) = 2*pi*(x + 6)^2
g(x) = 2pi*x^2 + 12pi*x + 72pi
The solution is given g(x) = f(x).
By graphing both functions (the green curve is the area of the rectangle, the orange one is the area of the circle). The two curves never do intercept, so the correct option is D.

URGENT CAN SOMEBODY PLEASE ANSWER THESE 2 QUESTIONS
Answers
Answer:
A: y=2x+4
B. 34° Celsius
Step-by-step explanation:
A:
Since the temperature goes up at a steady rate of 2 degres per minute, we can assume that 2 is our slope. Since the graph shows us that 4 is the y-intercept, we can substitute both the slope and y-intercept into the equation of a line, or y=mx+b. (m is our slope and b is our y-intercept.)
Doing so gives you:
[tex]y = 2x + 4[/tex]
B.
Using the above formula (y=2x+4), we can substitute x with 15 (since x is the minutes that pass).
Doing so gives you y=30+4, the sum of which is 34.
Therefore, the answer should be 34° Celsius.

It is given that alyssa's favorite tennis team has 8 players on them. She has taken a picture with every single athlete individually and wants to post some of the pictures on her wall. But she only wants to post 3 pictures on her wall.
For this we hve to use factorials. In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. The factorial of n also equals the product of n with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product.

Which of the following represents a function?
Please help
Answers
Answer:
(2,3),(4,3),(-2,-3),(-4,-3)
Step-by-step explanation:
A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).
This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.
The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.
A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.
In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:
(5,1),(5,2),(5,3),(5,4)
Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.

If 1600 square centimeters of material is available to make a box with a square base and an open top, find the largest possible volume of the box.
Answers
The largest possible volume of the box is 6158.394 cm^3.
Define the dimensions of the box to be L, W, and H.
Square base, L = W
Area: A = L^2 * H
Surface Area (Base + Area of 4 sides):
1600 = L^2 + 4 (L*H) ⇒ H = (1600 - L^2) / (4L)
Area: A = 400L - (1/4)L^3
Maximum (Derivative) A' = 400 - (3/4)L^2
Solving for 0
0 = 400 - (3/4)L^2
L^2 ⇒ (40 * SQRT(3)) / 3 = 23.094 (Maximum)
Solving for dimensions, known L=23.094
L = 23.094 cm
W = 23.094 cm
H ⇒ (1600 - L^2) / (4L) = (20 * SQRT(3) / 3) = 11.547 cm
Volume ⇒ L*W*H = 6158.394 cm^3
To locate the most viable extent, add the greatest viable mistakes to every dimension, then multiply. To find the minimum viable volume, subtract the greatest feasible mistakes from each measurement, then multiply.
Volume is a scalar amount expressing the amount of 3-dimensional area enclosed by a closed surface. For example, the gap that a substance or 3-D shape occupies or consists of.

Suppose it is known that the individual lost more than 12 pounds in a month. Find the probability that he lost less than 19 pounds in the month.
Answers
The probability that he lost less than 19 pounds is 7 / 9.
According to statement
The weight loss by individual is 12 Pounds
So, by uniform distribution probability
P(c ≤ x ≤ d) = (d - c) / (b - a)
Substitute the values in it then
P(12 ≤ x ≤ 19) = (19 - 12) / (20 - 11)
P(12 ≤ x ≤ 19) = 7 / 9
So, the probability that he lost less than 19 pounds is 7 / 9.
