For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Judy’s Cake Shop makes fresh cakes to customer orders. After receiving the order by Judy’s assistant, which takes 2 minutes, Judy then takes 8 minutes to mix the ingredients for the cake and loads a cake pan for baking. Then the cake is put into the oven for 30 minutes. The oven can hold three cakes at one time. When the cake is taken out of the oven, it is cooled for 1 hour. The assistant then takes 2 minutes to pack the cake for pickup and bills the customer, which takes 3 minutes. a. What is the capacity of the process, and what is the bottleneck? b. What is the throughput time for a typical cake? c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Time taken to receive order = 2 minutes

Ingredient mixing and cake loading = 8 minutes

Baking time = 30 minutes

Number of cakes oven can hold at a time = 3

Cooling time = 1 hour = 60 minutes

Cake packing = 2 minutes

Billing customer = 3 minutes

a. What is the capacity of the process, and what is the bottleneck?

The capacity of the process:

Within an hour : two bakings can be done =(30 minutes * 2) = 60 minutes

Also oven can hold 3 cakes, so, 3 cakes can be baked at a time.

Hence, 3 cakes in 30 minutes ;

6 cakes in an hour;

Hence, capacity of the process is 6cakes per hour.

The bottleneck is the oven, because if the number of ovens were to be increased, the process capacity will increase, similarly, if one of the oven gets faulty, then the process capacity reduces further.

b. What is the throughput time for a typical cake?

The throughput time, is the summation of all the time taken to fully complete an order :

Receipt of order + mixing + baking + cooling + packing + billing

2 + 8 + 30 + 60 + 2 + 3 = 105 minutes

c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?

(Throughput time / 60) * average number of order

(105/60) * 5

= 1.75 * 5

= 8.75

The baker has 42 kilograms of flour. She uses 8 kilograms each day.after how many days will she need to buy more flour?

Answers

Answer:

5 days 6hours

Step-by-step explanation:

Given data

total amount of flour=42kg

number of kg used per day=8kg

Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted

divide 42 by 8 we have

42/8=5.25------0.25 days to hours is 6hours

So it will take 5 days 6hours

Kathy and her brother Clay recently ran in a local marathon. The distribution of finishing time for women was approximately normal with mean 259 minutes and standard deviation 32 minutes. The distribution of finishing time for men was approximately normal with mean 242 minutes and standard deviation 29 minutes. The finishing time for Clay was 289 minutes. Calculate and interpret the standardized score for Clayâs marathon time. Show your work.

Answers

Answer:

Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Step-by-step explanation:

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).

Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,

[tex]Z=\frac{x-\mu}{\sigma}\sim N(0, 1)[/tex]

This, z-score is known as the standardized score.

It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.

The finishing time for Clay was x = 289 minutes.

Compute Clay's z-score as follows:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

   [tex]=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68[/tex]

Thus, Clay's standardized score is 1.68.

That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

John bought a car for $36,000, he didn't have enough money to buy the car totally, so he gave $1000 monthly, how much money did he give after 1 year, and how much does he has to give more?

Answers

There are twelve months in a year, and he pays $1000 a month, so we get [tex]\$1000*12 = $12,000[/tex] spent in a year. He originally needed to spend $36,000, so he has [tex]\$36,000-\$12,000 = \$24,000[/tex] left.

Please mark as Brainliest if you found this helpful.

Answer:

He payed 12,000 in one year

John has to pay $24000

Step-by-step explanation:

Car cost = $36,000

He gave Monthly = $1000

How much money did he give in a year?

1 year = 12 months

So

$1000 x 12 = 12,000

How does he have balance?

$36,000 - $12,000 = $24,000

John payed $12000 in one year, and has to pay $24000 more to own the car.

Hope you understand

Graph 1

coordinates : (0,-5) (-6,-2)

m = (y2-y1)/(x2-x1)

m = (-2-(-5))/(-6-0)

m = 3/-6 = -1/2

Substitute the values,

y = mx + c

-2 = (-1/2)(-6) + c

-2 = 3 + c

c = -5

Thus, equation is y = -1/2x -5

Graph 2

coordinates : ( 4,-2) (-5,3)

m = (y2-y1)/(x2-x1)

m = (3-(-2))/(-5-4)

m = 5/-9

Substitute the values,

y = mx + c

-2 = (-5/9)(4) + c

-2 = -20/9 + c

c = 2/9

Thus, the equation is y = -5/9 + (2/9)

The Air Quality Index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air. Over 100 is “Unhealthy”.
The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n = 1.76 t squared minus 13.32 t + 41.00
