question 8 options: the caller times at a customer service center has an exponential distribution with an average of 22 seconds. find the probability that a randomly selected call time will be less than 30 seconds? (round to 4 decimal places.) answer:
The probability that a randomly selected call time will be less than 30 seconds is approximately 0.7445.
The problem involves exponential distribution which is a standard continuous distribution. The probability density function of this distribution is given by -
f(x) = θe^(-θx) ; where θ is a parameter and characteristic of the distribution, x is the random variable.
Also, the mean for an exponential distribution is given by u = 1/θ .
In the question it is 22 seconds.
So, the value of θ is 1/22.
Now, we have to find P(X<30) where X is the random variable denoting the calling time in seconds.
P(X<30) is nothing but F(x) at x = 30 seconds, i.e. cumulative distribution function. For an exponential distribution , F(X) is given by -
P(X<x)= F(X) = 1- e^(-θ x) , where x>0.
Putting θ = 1/22 and x= 30 in F(X) , we get -
F(X) = 1-e[(-1/22)30] = 1- 0.2555 = 0.7445 which is P(X<x) = P(X<30) = 0.7445.
So, the probability that a randomly selected call time will be less than 30 seconds is approximately 0.7445.

Now, According to the question:
Normal Approximation to Binomial:
The normal distribution is used to approximate for the binomial distribution. The condition when binomial distribution is approximated to normal is that n should be large and probability should be close to 0.5
"Information available from the question"
n = 30
Probability, p(heads) = 1/2
Since sample size is large, we check for normal approximation.
np = 30(1/2) = 15
and, n(1 - p) = 30(1 - (1/2)) = 15 both are greater than 5, we use normal approximation.
Mean, μ = np = 30(1/2) = 15
Standard deviation, σ = [tex]\sqrt{np(1-p)}[/tex]
Standard deviation, σ = [tex]\sqrt{30(1/2)(1-1/2)}[/tex]
Standard deviation, σ =2.739
We have to find P (X ≥ 15). Using continuity correction, we deduct 0.5
P(X ≥ 15) = P(X > 14.5)
The respective Z-score with X = 14.5 is
Z = (x - μ)/ σ
Z = (14.5 - 15)/2.739
Z = -0.18
Now, we use z-tables to find probability greater than -0.18
P (Z > -0.18) = 1 - 0.4289 = 0.5714

Answer: The answer is 3.
Step-by-step explanation:
a. squares with sides of length x are cut out of each corner of a rectangular piece of cardboard measuring 3 ft by 4 ft. the resulting piece of cardboard is then folded into a box without a lid. find the volume of the largest box that can be formed in this way.
The largest box that can be formed has a volume of 20 cubic feet.
Let's call the side length of the square cutout x. The original piece of cardboard measures 3 feet by 4 feet, so the dimensions of the piece of cardboard after the cutouts are made are (3 - 2x) by (4 - 2x).
When this piece is folded into a box, the length and width of the box will be (3 - 2x) and (4 - 2x) respectively. The height of the box will be x, as that is the height of the cutout squares.
The volume of the box can be found by multiplying the length, width, and height: V = (3 - 2x)(4 - 2x)x
We want to find the maximum volume, so we need to differentiate the expression for the volume and set it equal to zero, and then solve for x.
dV/dx = 2x(4 - 2x) - (3 - 2x)(2x) = 0
2x(4 - 2x) = (3 - 2x)(2x)
2x(4 - 2x) = 2x^2 - 6x^2
-4x^2 + 4x = 0
x(4 - x) = 0
x = 0 or x = 4
Since the side length of the cutout square cannot be negative, we reject x = 0 and keep x = 4. So, the maximum volume will occur when the side length of the cutout squares is 4 feet.
Substituting x = 4 into the expression for the volume, we find:
V = (3 - 2x)(4 - 2x)x = (3 - 2x)(4 - 2x) = (3 - 2x)(4 - 2x) = (3 - 8)(4 - 8) = -5 * -4 = 20 cubic feet
So, the largest box that can be formed has a volume of 20 cubic feet.
Therefore, The largest box that can be formed has a volume of 20 cubic feet.

dV/dx = 2x(4 - 2x) - (3 - 2x)(2x) = 0
2x(4 - 2x) = (3 - 2x)(2x)
2x(4 - 2x) = 2x² - 6x²
-4x² + 4x = 0
x(4 - x) = 0
x = 0 or x = 4
Since the side length of the cutout square cannot be negative, we reject x = 0 and keep x = 4. So, the maximum volume will occur when the side length of the cutout squares is 4 feet.

Find the slope of the line that passes through G(−3, 2) and H(7, 2) .
Answer:
The slope of the line that passes through G(-3, 2) and H(7, 2) is 0.
Step-by-step explanation:
The slope of a line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
In this case, we have two points G(-3, 2) and H(7, 2):
m = (2 - 2) / (7 - (-3))
m = 0
Therefore, the slope of the line that passes through G(-3, 2) and H(7, 2) is 0.
solve the equation z2 z 1 = 0 for z = (x,y) by writing (x,y)(x,y) (x,y) (1,0) = (0,0)
The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).
x2 - xy + y2 - x = 0
x(x - y) + y(y - 1) = 0
x(x - y) = 0 and y(y - 1) = 0
x = 0 or x = y and y = 0 or y = 1
Therefore, the solutions are (0,0), (0,1), (1,0), and (1,1).
The equation z2 z 1 = 0, when written as (x,y)(x,y) (x,y) (1,0) = (0,0), can be manipulated to x2 - xy + y2 - x = 0. By factoring out the x and y terms, the equation can be rearranged to x(x - y) + y(y - 1) = 0. This then can be further simplified to x(x - y) = 0 and y(y - 1) = 0. The solutions of x = 0 or x = y and y = 0 or y = 1 can then be found. Therefore, the solutions of the equation are (0,0), (0,1), (1,0), and (1,1).

That means we have success and failures.
X = 1 means that we roll exactly 6 in the 3 trials. This means that the probability of rolling a 6 in this situation is 3(0.4)(0.6)2.
The probability of rolling a 6 in any given trial is 0.6 since Mrs. Chauvet's cube is unfair. The probability of getting a 6 in two of the three trials is 3(0.4)(0.6)2, while the probability of rolling a 6 in all three trials is 1(0.6)3. This means that the chance of rolling a 6 in any combination among three trials is the sum of the probabilities of rolling a 6 in each trial (0.6 + 0.6 + 0.6 = 1.8).
The probability of rolling a 6 exactly once in three trials is 3(0.4)(0.6)2, which is the probability of getting a 6 in one of the three trials and not getting a 6 in the other two.

If a person standing at the top of the building of height 50 ft is looking at her daughter standing at a distance of 30 ft away from the building, what will be the angle of depression formed?
The angle of depression is 32°.
What is the depression's angle?
The angle of depression is the angle formed when the item being seen is below the observer's level between the horizontal line and the line of sight of the observer.
The angle of depression is the angle formed by the horizontal axis and the downward axis of a line of sight. As an example, if you were perched on top of a hill or other structure and looked down at an object, you might determine the angle of depression. To measure these angles, a theodolite or a clinometer can be used. The maximum depression angle is 90 degrees. It can't be possible because any rational spectator would turn around the instant the object passed beneath him.
Due to the fact that AB is perpendicular to B and AD is the horizontal line of sight, we can conclude that AD AB (given).
∴ ∠DAB = 90°.
We can express this as DAB = DAC + BAC.
alternatively, 90° = ∠DAC + 58°
alternatively, ∠DAC = 90° - 58° = 32°.

Synthetic division and the rational root theorem can be used to demonstrate this. According to the rational root theorem, p must divide the constant term and q must divide the leading coefficient if p/q is a rational root of the polynomial f(x). The constant term in this example is -6, the leading coefficient is 4, and the potential rational roots are 1, 2, 3, and 6.
When we divide 4x3 + 10x2 - 6x by 2x - 1 using synthetic division, we arrive at the following result:
4x^3 + 10x^2 - 6x = (2x - 1) (2x^2 + 8x + 6)
We can then factor the remaining quadratic, 2x^2 + 8x + 6, as (x + 3)(2x + 2).
Thus, the completely factored form of 4x^3 + 10x^2 - 6x is:
4x^3 + 10x^2 - 6x = 2x(x + 3)(2x - 1)

The length of a rectangular i three time it width, and the height i four more than the width. Write an expreion for the volume of the rectangular prim in term of width
An expression for the volume V of the rectangular prism in terms of its width w is V = ( 3W³ + 12W² ) Units³
What is the rectangular prism?A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism. A rectangular prism also refers to a cuboid. A cuboid and a rectangular prism have the same cross-section.Its length, width, and height are its three dimensions. Rectangular tissue boxes, school notebooks, laptops, fish tanks, big buildings like freight containers, rooms, storage sheds, etc. are a few instances of rectangular prisms in daily life.A three-dimensional object called a rectangular prism has rectangles on each of its faces. The rectangular prism is a cube if all of its faces are squares. A rectangular prism's volume is a measurement of the inside volume.Given data :
we know that
The volume of a rectangular prism is equal to
V = LWH ------> Equation A
where
L is the length
W is the width
H is the height
we know that
L = 3W ----> Equation B
H = W + 4 ------> Equation C
substitute equation B and equation C in equation A
V = ( 3W ) (W) ( W + 4 )
Apply distributive property
V = ( 3W³ + 12W² ) units³

Write the equation of the line in slope-intercept form (y=mx+b):
Answer: y = 3x + 0 OR y = 3x
Step-by-step explanation:
M = slope. rise/run. compare the points on the line by how much they rise and how much they run. In this case it is 3/1 (3). the B = the y-intercept. (the point where the line meets the y line, in this case the line meets at the origin which is 0.)
How do you show that f is continuous on − [infinity] [infinity]?
It follows that continuity at infinity is provided by having the same limit while approaching it from either side, i.e., the limit towards + and, which makes sense based on your understanding.
When a function can be extended to P1, it is said to be "continuous at infinity" (R).
What is the limit?Calculus's idea of the limit describes how a function behaves as its input gets closer to a particular value. As long as the limit is present, the value that f(x) approaches as x moves closer to c is represented by the notation lim(x -> c) f(x), which stands for the limit of a function at the point x = c.
You must demonstrate that all three of the following conditions are true in order to prove that a function f is continuous on an interval:
Every point in the interval has f specified, and the interval has f's bound.
For each and every > 0, there is a corresponding > 0 such that |x - c| implies |f(x) - f(c)| for all x and all c in the interval.
F is considered to be continuous on the interval if these requirements are met.
