The Edward James Toy Company uses a Kanban system to make plastic wheels that are a component of several toys. The waiting time for a container of the wheels during production is 0.25 day; average processing time is 0.15 day per container. Each container holds 200 wheels. The company uses 2000 wheels a day in the production of its products. Using a policy variable of 5%, calculate the number of Kanban containers needed for the wheels.
Answer:
4.2 kanban containers required
Step-by-step explanation:
Given the following information :
Waiting time = 0.25 days
Average peocessing time = 0.15 days / container
Daily usage (Demand rate) = 2000 per day
Container capacity = 200 wheels
Policy variable ( Alpha) = 5% = 0.05
Therefore, number of kanban containers needed for the wheels can be calculated using:
(Number of containers(x) * container size) = (Demand rate (waiting time + processing time)*(1 + alpha))
x * 200 = 2000(0.25 + 0.15)*(1 + 0.05)
200x = 2000(0.40)*(1.05)
200x = 840
x = 840 / 200
x = 4.2

A small grain silo is filled with wheat at the end of each season. If the silo is only half full, how many cubic meters of wheat have been stored? Group of answer choices 339.29 m³ 223.19 m³ 169.65 m³ 113.10 m³
Answer:
Volume of wheat = 147.26 m³ (check the explanation)
Step-by-step explanation:
The question still lacks some details such as the size of the silo. We will go forward by assuming the size of the silo to aid our calculation. Silos are cylindrical storage structures that range from 3 - 27 m in diameter and 10 - 90 m in height. For the purpose of this question, let's assume that the size of the silo is 5 m (diameter) by 15 m (height).
Let's list out the parameters to be used:
diameter (D) = 5 m; r = D ÷ 2 ⇒ r = 5/2 = 2.5 m,
height (h) = 15 m
Volume of silo = πr²h = π * 2.5² * 15
V (silo) = 294.52 m³
The silo is half full ⇒ ½ * V
Volume of wheat stored is given by half of the silo volume, since the silo is half-full
V (wheat) = ½ * 298.52
V (wheat) = 147.26 m³

Gracie has 5555 pet bunnies that love to eat whole carrots. She has 39393939 carrots to feed the bunnies. Gracie will use as many carrots as she can and give each bunny the same number. How many carrots will each bunny get?
Answer:
7,091.61
Step-by-step explanation:
If you have a number 1. (39393939) and you have another number 2. (5555) and you want the second number to get the same amount as the other numbers but evenly, you need to divided the first number with the second number.
Ex. 39393939/ 5555 = 7,091.61
So each bunny will get 7,091.61 carrots.
Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frog population
Answer:
Step-by-step explanation:
This is exponential, of the form
[tex]y=a(b)^x[/tex] where a is the initial amount and b is the growth/decay rate. If Ginny begins the study with 1200 frogs in the population, our a value is 1200.
If the population is decreasing 3% per year, it is decreasing 100% - 3% = 97% which, as a decimal, is .97. Our exponential function, then, is
[tex]y=1200(.97)^x[/tex]

Your friend swims on the school team. In her first four races, her times are 26.3, 28.4, 25.6 and 29.1. Which time listed for her next race would make the range larger? A. 25.2 B. 26.1 C. 28.0 D. 29.1
Answer:
A.) 25.2
Step-by-step explanation:
Given the following :
Times in first four races :
26.3, 28.4, 25.6 and 29.1
The range of a list of values is the difference between the maximum and minimum value of the list or data.
In her first four races :
Range = 29.1 - 25.6 = 3.5
Value of range in her first four races = 3.5
In other to make the range larger:
Either she has a value less than the least time in her previous four races or she has a value greater than the maximum value of her previous race in her next race.
With a time of 25.2 in her next race : least value in the data will be 25.2
Range = 29.1 - 25.2 = 3.9
With a time of 26.1 in her next race :
Range = 29.1 - 25.6 = 3.5
With a time of 28.0 in her next race :
Range = 29.1 - 25.6 = 3.5
With a time of 29.1 in her next race :
Range = 29.1 - 25.6 = 3.5
Answer:
25.2
Step-by-step explanation:
Your friend swims on the school team.
In her first four races, her times are 26.3, 28.4, 25.6, and 29.1 seconds.

Which statement about the slope of the line is true?
The slope from point o to point A is one-fourth times the slope of the line from point A to point B.
The slope from point o to point A is four times the slope of the line from point A to point B.
Olt is throughout the line
It is -4 throughout the line.
Answer:
It is - [tex]\frac{1}{4}[/tex] throughout the line
Step-by-step explanation:
The points O, A and B lie on the line and so the slope will be the same for OA, OB and AB
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = B(- 12, 3) and (x₂, y₂ ) = O(0, 0)
m = [tex]\frac{0-3}{0+12}[/tex] = [tex]\frac{-3}{12}[/tex] = - [tex]\frac{1}{4}[/tex]
Thus the slope is - [tex]\frac{1}{4}[/tex] throughout the line.
35% off a phone = £78 how much was the phone before the discount prices?
Answer:
£120
Step-by-step explanation:
Given that
The price after reduction = £78
So, 65% = £78.
We have to calculate 100 %
To do so, find 5% and multiply that by 20
65% = £78
5% = 78/13 = £6
So, 100% = 6 x 20 = £120

Help please! How would i solve this?
Answer:
B is correct
Step-by-step explanation:
What is need to be done here is to set up an exponential equation for both scenario.
The exponential equation to set up is as follows;
V = P(1 + r)^t
It looks exactly like an equation used to get the amount on a compound interest after a stipulated number of years.
We have the following definitions;
V is the future value.
P is the present value
r is the rate in percentage
t is the time in years
So, for A, we have;
Kindly note that 4% = 4/100 = 0.04
110,000(1+0.04)^t = 110,000(1.04)^t
For B, we have;
6/100 = 0.06
100,000(1+0.06)^t = 100,000(1.06)^t
Now expected value of B is twice that of A.
The equation that defines this would look like;
100,000(1.06)^t = 2(110,000(1.04)^t)

An evergreen nursery usually sells a certain shrub after 5 years of growth and shaping. The growth rate during those 5 years is approximated by dh/dt = 1.5t + 4, where t is the time in years and h is the height in centimeters. The seedlings are 12 centimeters tall when planted (t = 0). (a) Find the height after t years.
Answer:
[tex]h(t) = 0.75t^2 + 4t + 12[/tex]
Step-by-step explanation:
The equation given calculates the derivative of the height in relation to the time, that is, the rate of change of the height. To find the equation for the height, we need to integrate this equation:
[tex]dh/dt = 1.5t + 4[/tex]
Multiplying both sides by 'dt', we have:
[tex]dh = (1.5t + 4)dt[/tex]
Using the integral in both sides:
[tex]\int dh = \int (1.5t + 4) dt[/tex]
[tex]h = 0.75t^2 + 4t + h(0)[/tex]
[tex]h = 0.75t^2 + 4t + 12[/tex]
So the height after t years is represented by this equation:
[tex]h(t) = 0.75t^2 + 4t + 12[/tex]
Solve the simultaneous equations 3x+y=8 X-3Y=11
Answer:
(7/2, -5/2)
Step-by-step explanation:
We can solve this multiple ways: Algebraically (Substitution or Elimination) or Graphically
Step 1: Write 1st equation in terms of y
y = 8 - 3x
Step 2: Substitute y of 2nd equation
x - 3(8 - 3x) = 11
Step 3: Solve for x
x - 24 + 9x = 11
10x - 24 = 11
10x = 35
x = 7/2
Step 4: Plug x to find y
3(7/2) + y = 8
21/2 + y = 8
y = -5/2
Answer:
Step-by-step explanation:
let's organize our information :
3x+y=8x-3y=11The trick here is to multiply x-3y=11 by -3 then add it to 3x+y=8 to get rid of x and get a normal equation
we get : -3x+9y= (-33)
then after the addition : 3x+y-3x+9y=8-33⇔ 10y=(-25)
so y=(-25)/10= -5/2
let's replace y by -5/2 in 3x+y=8 3x-5/2 =8⇔ x= 21/6so y= (-5/2) and x= 21/6

what is the critical value method and pvalue method
Answer:
[tex]t=\frac{11.5-10}{\frac{4.5}{\sqrt{100}}}=3.333[/tex]
Critical value
The significance is 5% so then [tex]\alpha=0.05[/tex] and [tex]\alpha/2=0.025[/tex] then the critical value for this case would be [tex] z_{\alpha/2}= 1.64[/tex]. Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true mean is higher than 10 mg
P value
The p value would be given
[tex]p_v =P(z>3.333)=0.000434[/tex]
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly higher than 10 mg
Step-by-step explanation:
Information given
[tex]\bar X=11.5[/tex] represent the sample mean
[tex]\sigma=4.5[/tex] represent the population standard deviation
[tex]n=100[/tex] sample size
[tex]\mu_o =10[/tex] represent the value that we want to test
[tex]\alpha=0.05[/tex] represent the significance level for the hypothesis test.
t would represent the statistic
[tex]p_v[/tex] represent the p value
Hypothesis to test
We want to test if the true mean is higher than 10mg, the system of hypothesis would be:
Null hypothesis:[tex]\mu \leq 10[/tex]
Alternative hypothesis:[tex]\mu > 10[/tex]
the statistic for this case would be given by:
[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex] (1)
Replacing we got:
[tex]t=\frac{11.5-10}{\frac{4.5}{\sqrt{100}}}=3.333[/tex]
Critical value
The significance is 5% so then [tex]\alpha=0.05[/tex] and [tex]\alpha/2=0.025[/tex] then the critical value for this case would be [tex] z_{\alpha/2}= 1.64[/tex]. Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true mean is higher than 10 mg
P value
The p value would be given
[tex]p_v =P(z>3.333)=0.000434[/tex]
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly higher than 10 mg
When testing gas pumps for accuracy, fuel-quality enforcement specialists tested pumps and found that 1334 of them were not pumping accurately (within 3.3 oz when 5 gal is pumped), and 5663 pumps were accurate. Use a 0.01 significance level to test the claim of an industry representative that less than 20% of the pumps are inaccurate. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.
Answer:
We accept H0, Therefore we conclude that there is no evidence to support the claim that less than 20% of the pumps are inaccurate.
Step-by-step explanation:
We have,
x = 1334
n = 1334 + 5663 = 6997
we have to:
p = x / n = 1334/6997 = 0.1907
The hypothesis is:
H0: P = 0.20
H1: P <0.20
P = 0.2 and Q = 1 - P = 0.8
the test statistic is:
Z = (p - P) / [(P * Q / n) ^ (1/2)]
replacing:
Z = (0.1907 - 0.20) / [(0.2 * 0.8 / 6997) ^ (1/2)]
Z = -1.96
now, the p-value is
P = 0.0250, from normal table, attached
Here p-value> 0.01, so we accept H0, Therefore we conclude that there is no evidence to support the claim that less than 20% of the pumps are inaccurate.
