A time-and-motion study measures the time required for an assembly-line worker to perform a repetitive task. The data show that the time required to bring a part from a bin to its position on an automobile chassis varies from car to car according to a Normal distribution with mean seconds and standard deviation seconds. The time required to attach the part to the chassis follows a Normal distribution with mean seconds and standard deviation seconds. The study finds that the times required for the two steps are independent. A part that takes a long time to position, for example, does not take more or less time to attach than other parts.
(a) Find the mean and standard deviation of the time required for the entire operation of positioning and attaching the part.
(b) Management’s goal is for the entire process to take less than seconds. Find the probability that this goal will be met. Show your work
The mean time of the entire operation is given by 31 seconds and standard deviation is approximately 4.47 seconds
mean time (μ₁) = 11 seconds
mean chassis time (μ₂) = 20 seconds
a)Total time taken = μ₁ + μ₂ = 11 +20 = 31 seconds
Now we will find the standard deviation:
standard deviation = √ (2²+4²) = √ 20 ≈ 4.47 seconds
b) The probability that the entire process will take less time:
Total time taken = 31 seconds
Less time taken will be 2 seconds for the entire time
P(T<30) = 30 - 31 / 4.47 = - 0.22
Now from the normal distribution table we get the p-value as :
p-value = 0.4129
Hence the required probability is 41.29 % .
The population or sample standard deviation and the standard error of a statistic are not the same thing, but they are related. The standard error of the sample mean is the standard deviation of the set of means computed by drawing an infinite number of repeated samples from the population and computing a mean for each sample.
The mean's standard error is estimated by dividing the sample standard deviation by the square root of the sample size, which matches the population standard deviation divided by the square root of the sample size.

Answer: The coefficient of the term with t^3 and q^14 in the expansion of (3t - q)^17 is 816 / 3.
Step-by-step explanation: The coefficient of the term with a certain power of t and a certain power of q in the expansion of a binomial raised to a power can be found using the binomial formula. The formula is given by:
Copy code
(a + b)^n = sum_{k=0}^n choose(n, k) * a^(n-k) * b^k
In this case, we have a = 3t, b = -q, and n = 17. We want to find the coefficient of the term with t^3 and q^14, which means we need to find the coefficient of the term with a^(n-k) = t^3 and b^k = q^14. Plugging these values into the formula, we get:
Copy code
(3t - q)^17 = sum_{k=0}^17 choose(17, k) * 3^(17-k) * (-1)^k * t^(17-k) * q^k
To find the coefficient of the term with t^3 and q^14, we need to find the value of choose(17, k) for k = 3. The binomial coefficient choose(n, k) is equal to the number of ways to choose k items from a set of n items. It can be calculated using the formula:
Copy code
choose(n, k) = n! / (k! * (n-k)!)
where n! is the factorial of n, which is the product of all positive integers less than or equal to n. For example, 5! = 5 * 4 * 3 * 2 * 1 = 120.
In our case, we have n = 17 and k = 3, so the coefficient we are looking for is:
Copy code
choose(17, 3) = 17! / (3! * (17-3)!) = 17 * 16 * 15 * 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / (3 * 2 * 1 * 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) = 17 * 16 / 3 = 816 / 3
Therefore, the coefficient of the term with t^3 and q^14 in the expansion of (3t - q)^17 is 816 / 3.

What is a linear equation in two variables?
An equation is said to be a linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
To solve for x, we can rearrange the equation to solve for x:
y = 30000 + 120x/x
Isolating x on one side of the equation gives:
x = 30000/(y - 120)
Substituting y = 150 into this equation gives:
x = 30000/(150 - 120)
This simplifies to:
x = 30000/30
Which simplifies to:
x = 1000
Hence, for x = 1000 cell phones, the average cost per cell phone will be $150.

(Round your answer to two decimal places.) 0.84 mile(s) down the coast
Least time required to reach the point Q as per the distance and the speed rate is equal to 2 hours.
As given in the question,
Nearest point on the coast is 2 miles far away
rate of the row = 1mile per hour
Walk at the rate of 3 miles per hour
Let 'x' hours be the least time to reach point Q.
Time = distance / speed
Time taken to reach the point Q = [√ 1 + ( 3 - x)² ]/ 3
Time taken to reach the coast = (√ 4 + x² ) / 1
Total time taken 't' = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3
To find least time dt/dx = 0
t = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3
⇒dt/dx = [ x / √ 4 + x² ] + ( 3 - x) / √( 10 -6x + x² )
⇒x / √ 4 + x² = ( x - 3) / √( 10 -6x + x² )
Squaring both the side we get,
x² / (4 + x²) = ( x - 3)² / ( 10 -6x + x² )
⇒3x² -24x +36 =0
⇒ x² -8x + 12 = 0

The parabola of y= has a vertex of (3, - 2) and a focus of (3, - 2 1/16) opens downward
The equation of the parabola is y = -1/4 x² + 3/2 x - 17/4. Where the vertex of the equation is at (3, -2) and the focus is at (3, -2 2/16) that opens downwards.
What is the equation of a parabola?The equation of the parabola with vertex at (h, k) is
y = a(x - h)² + k
The focus of the parabola is represented by (h, k + 1/4 a).
Calculation:It is given that, the vertex of the parabola is (h, k) = (3, -2)
And the focus of the parabola is (h, k + 1/4 a) = (3, -2 1/16)
From the focus point, we can calculate the value of 'a'.
(h, k + 1/4 a) = (3, -2 1/16)
⇒ k + 1/4 a = -2 1/16 = -33/16
⇒ -2 + 1/4 a = -33/16
⇒ 1/4 a = -33/16 + 2
⇒ 1/4 a = -1/16
⇒ a = -1/16 × 4
∴ a = -1/4
Since a is negative the parabola is downwards.
Now, the equation of the parabola is
y = a(x - h)² + k
On substituting the values, we get
y = -1/4(x - 3)² - 2
= -1/4(x² - 6x + 9) - 2
= -1/4 x² + 3/2 x -9/4 - 2
= -1/4 x² + 3/2 x - 17/4

Roll one-8 sided die 10 times. The probability of getting exactly 3 sevens in those 10 rolls is given by .
The binomial probability of getting exactly 3 sevens in 10 rolls of an 8-sided die is approximately 0.0142 or 1.42%.
Given: Roll an 8-sided die 10 times and to find the probability of getting exactly 3 sevens in those 10 rolls.
Formula: The probability of getting exactly "k" successes in "n" trials of an event with a probability "p" of success in a single trial is given by the binomial probability formula:
P(k successes in n trials) = [tex]C(n , k) * p^k * (1 - p)^{(n - k)}[/tex]
where:
C (n , k) represents the number of combinations of "n" things taken "k" at a time, and p is the probability of success in a single trial.Step1
Calculate the probability of rolling a seven on an 8-sided die (p).
Since there is 1 "success" outcome (rolling a seven) out of 8 possible outcomes (8-sided die),
p = 1/8.
Step 2
Plug the values into the binomial probability formula for getting exactly 3 sevens in 10 rolls:
P(3 sevens in 10 rolls) = [tex]C(10, 3) * (1/8)^3 * (1 - 1/8)^{(10 - 3)}[/tex]
On subtracting gives:
=C(10, 3) * (1/8)^3 * (7/8)^{7}
Plugging the value of C(10,3) = 120 in the above equation:
= 120 * (1/8)^3 * (7/8)^{7}
Step 3:
Calculate the final answer using the formula:
P(3 sevens in 10 rolls) = 120 * (1/512) * (343/512)
≈ 0.0142
Therefore, the binomial probability of getting exactly 3 sevens in 10 rolls of an 8-sided die is approximately 0.0142 or 1.42%.

whats the domain,range, and y-intercept and tell me if its exponential or linear.
k(x)=50(1.3)^x
0.3% is the percentage rate of increase in exponential function.
What exactly makes a function exponential?
A mathematical function using the following formula is an exponential function: f (x) = an x. where an is a constant known as the function's base and x is a variable.
The transcendental number e, or roughly 2.71828, is the most often encountered exponential-function base.
We have,
y = 50( 1.3)ˣ
The equation represents exponential growth because the growth factor is greater than 1.
The general form equation is
y(x)= a(1-r)^x such that r is the growth percent.
1 + r = 1.3
r = 0.3 ⇒ 0.3%

0. Mardo ordered 2 reclining chairs for $230 each and a coffee table for $350. The shipping cost is $100. Marco is going to pay off his bill in 5 equal payments. How much is each of Marco's payments?
The amount of each Marco's payments for the 2 reclining chairs, a coffee table including with shipping cost is found as $182.
Explain the division operation?Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people belong to each group after a fair distribution is the basic objective of division.The data for the given question-
Mardo placed an order for a coffee table and two recliners for a total of $230 each. The price of shipping is $100. Marco will settle his debt in five equal payments.Thus, the total cost becomes-
Total cost = 2 x reclining chairs + coffee table + shipping cost
Total cost = 2 x 230 + 350 + 100
Total cost = $910
For the amount of each payment when there are 5 equal payments.
Total cost = 910/5
Total cost = $182
Thus, the amount of each Marco's payments for the 2 reclining chairs, a coffee table including with shipping cost is found as $182.
