The company actually used 22,500 pounds in production. Journalize the entry to record the standard direct materials used in production. For a compound transaction, if an amount box does not require an entry, leave it blank.
Answers
Answer:
Dr work-in-process $ 241,500.00
Cr materials $236,250
Cr direct material quantity variance $ 5,250.00
Step-by-step explanation:
The cost of the materials using standard price per pound of $10.5 is computed below:
standard cost=4,600*5*$10.5=$241,500.00
The above is debited to work in process account.
The actual cost of materials used =22,500*$10.5=$236,250.00
Since the actual cost materials is $ 236,250.00 ,the materials ledger is credited with $ 236,250.00
The direct material quantity variance=$241,500-$236,250=$5,250

The Department of Highway Improvements, responsible for repairing a 25-mile stretch of interstate highway, wants to design a surface that will be structurally efficient. One important consideration is the volume of heavy freight traffic on the interstate. State weigh stations report that the average number of heavy-duty trailers traveling on a 25-mile segment of the interstate is 72 per hour. However, the section of highway to be repaired is located in an urban area and the department engineers believe that the volume of heavy freight traffic for this particular section is greater than the average reported for the entire interstate.
To validate this theory, the department monitors the highway for 50 1-hour periods randomly selected throughout the month. Suppose the sample mean and standard deviation of the heavy freight traffic for the 50 sampled hours are:
Sample mean = 74.1 standard deviation = 13.3
a) Do the data support the department's theory? Use α = 0.10 to come to a conclusion based on a large sample test.
Answers
Answer:
[tex]t=\frac{74.1-72}{\frac{13.3}{\sqrt{50}}}=1.116[/tex]
The degrees of freedom are given by:
[tex]df=n-1=50-1=49[/tex]
Now we can calculate the p value with the following probability:
[tex]p_v =P(t_{(49)}>1.116)=0.135[/tex]
Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 72 per hour.
Step-by-step explanation:
Information provided
[tex]\bar X=74.1[/tex] represent the sample mean
[tex]s=13.1[/tex] represent the sample standard deviation
[tex]n=50[/tex] sample size
[tex]\mu_o =72[/tex] represent the value that we want to test
[tex]\alpha=0.1[/tex] represent the significance level
t would represent the statistic
[tex]p_v[/tex] represent the p value
Hypothesis to test
We want to analyze if the true mean for this case is higher than 72, the system of hypothesis would be:
Null hypothesis:[tex]\mu \leq 72[/tex]
Alternative hypothesis:[tex]\mu > 72[/tex]
The statistic is given by:
[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex] (1)
Replacing the info we got:
[tex]t=\frac{74.1-72}{\frac{13.3}{\sqrt{50}}}=1.116[/tex]
The degrees of freedom are given by:
[tex]df=n-1=50-1=49[/tex]
Now we can calculate the p value with the following probability:
[tex]p_v =P(t_{(49)}>1.116)=0.135[/tex]
Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 72 per hour.
An outdoor club conducted a survey of its members. The members were asked to state their preference between skiing and snowboarding. Each member had to pick one. Of the 60 males, 45 stated they preferred to snowboard. Twenty-two of the 60 females preferred to ski. What is the relative frequency that a male prefers to ski?
Answer:
Answers
Answer:
0.25
Step-by-step explanation:
Data provided in the question
Number of males = 60
Number of stated preferred to snowboard = 45
Number of females preferred to ski = 22
Based on the above information, the relative frequency male preferred to ski is
Before computing this first we have to calculate the number of ski picked which is
= Number of males - Number of stated preferred to snowboard
= 60 - 45
= 15
Now the relative frequency is
[tex]= \frac{Number\ of\ ski}{Number\ of\ males}[/tex]
[tex]= \frac{15}{60}[/tex]

denise bought a life insurance policy from donald, and if denise dies, the insurance company has to pay debra, whose son is douglas. who is the beneficiary of the life insurance policy? a. donald b. debra c. denise d. douglas
Answers
The correct answer is B. Debra
Explanation:
The word "beneficiary" is used to describe the individual that receives a benefit. In the case of a life insurance policy, the receiver is always the person that receives money and other benefits when the person covered by the policy dies. This implies that in the case presented, Denise is the individual covered by the policy and the beneficiary is Debra because she will receive the money once Denise dies, and therefore she is the recipient of the benefits related to the insurance policy.
what’s the length of the tunnel?
Answers
Answer:
3.40 km
Step-by-step explanation:
Given two sides and the angle between them, the Law of Cosines is useful for finding the remaining side of the triangle.
If we call the vertices of the triangle H, P, Y, then the Law of Cosines tells you ...
HY² = HP² +YP² -2HP·YP·cos(P)
HY² = 6² +7² -2·6·7·cos(29°) = 85 -84·cos(29°) ≈ 11.531944
HY ≈ √11.531944 ≈ 3.40 . . . . km
The length of the tunnel is about 3.40 km.
There is a bag filled with 3 blue, 4 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of exactly 1 red?
Answers
Answer:
22.22%
Step-by-step explanation:
If it is exactly a red, it means that it is removed on the first or second attempt, but only once, in this case it does not matter if it is on the first or second attempt because the marble is returned to the bag.
So suppose that on the first attempt red is drawn, the probability would be:
4 / (3 + 4 + 5) = 4/12 = 1/3
Now, on the second attempt, it is not to draw a red, it must be green or blue, so it would be:
(5 + 3) / (3 + 4 + 5) = 8/12 = 2/3
The final probability then is:
1/3 * 2/3 = 0.2222
that is, the probability is 22.22%
An element with a mass of 740 grams decays by 28.4% per minute. To the nearest minute, how long will it be until there are 30 grams of the element remaining?
Answers
Answer:t=9.6 minutes
Step-by-step explanation:
Given
mass of element is [tex]A_o=740\ gm[/tex]
Decay rate [tex]r=28.4\%\ \text{per minute}[/tex]
and we know
Amount of exponential decay is given by
[tex]A=A_o[1-r]^t[/tex]
Where [tex]A_0=\text{Initial amount}[/tex]
[tex]\text{A=Accumulated amount}[/tex]
[tex]\text{r=rate}[/tex]
[tex]\text{t=time}[/tex]
Substituting values we get
[tex]\Rightarrow 30=740[1-0.284]^t[/tex]
[tex]\Rightarrow \dfrac{30}{740}=0.716^t[/tex]
[tex]\Rightarrow 0.0405=0.716^t[/tex]
taking log both sides we get
[tex]\Rightarrow\ \ln (0.0405)=t\times \ln (0.716)[/tex]
[tex]\Rightarrow t=\dfrac{\ln (0.0405)}{\ln (0.716)}[/tex]
[tex]\Rightarrow t=9.598\approx 9.6\ \text{minutes}[/tex]

Working alone, Dan can sweep a porch in
15 minutes. Alberto can sweep the same
porch in 11 minutes. If they worked
together how long would it take them?
Answers
Answer:
It will take them 6.35 minutes
Step-by-step explanation:
The question can be solved when you know how much of the job can be done in minutes.
Therefore if Dan can do the job in 15 minutes he will be to sweep 1/15 of the porch in 1 minutes. Alberto can do the same job in 11 minutes, in 1 minutes he will do 1/11 of the job.
let
a = combined time together
1/15 + 1/11 = 1/a
(11 + 15)/165 = 1/a
26/165 = 1/a
cross multiply
26a = 165
divide both sides by 26
a = 165/26
a = 6.34615384615
a ≈ 6.35 minutes
It will take them 6.35 minutes

What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Given two rectangular containers.
We have to find the surface area of both the containers.
Surface area of a rectangular prism = 2[(l × w) + (w × h) + (l × h)]
Here l, w and h are the length, width and height of the rectangular prism.
For the first rectangular prism,
Surface area = 2 [(5 × 4) + (4 × 7) + (5 × 7)] = 166 cm²
For the second rectangular prism,
Surface area = 2 [(4 × 3) + (3 × 10) + (4 × 10)] = 164 cm²
Hence the container on the right is made of 2 centimeters squared more plastic.

the answer is 60
Answer:60
Step-by-step explanation:if the equation is 50/.5-40, the first step is to turn them into fractions 50/1 and 50/100 (or 1/2) then you flip the second fraction and change the sign to multiply so it would be 50/1x2/1.
Y=50/.5-40
Y=50/1x2/1-40
Y=100-40
That leaves you with 100/1 (or 100). Then you subtract 40 from 100
100-40=60
