Minstrel Manufacturing uses a job order costing system. During one month, Minstrel purchased $198,000 of raw materials on credit; issued materials to production of $195,000 of which $30,000 were indirect. Minstrel incurred a factory payroll of $150,000, of which $40,000 was indirect labor. Minstrel uses a predetermined overhead rate of 150% of direct labor cost. The total manufacturing costs added during the period is:
Answer:
$440,000
Step-by-step explanation:
Direct material:
= $195,000 - $30,000
= $165,000
Direct labor:
= $150,000 - $40,000
= $110,000
Manufacturing overhead:
150% of direct labor cost.
= $110,000 x 150 ÷ 100
= $16,500,000 ÷ 100
= $165,000
Total manufacturing costs:
= $165,000 + $110,000 + $165,000
= $275,000 + $165,000
= $440,000
The total manufacturing costs added during the period is: $440,000

What is an equation for "five more than the
product of 7 and a number t is 10?"
Answer:
Option (B) will be the correct option.
Step-by-step explanation:
Statement states "five more than the product of seven and a number t is 10."
Split this statement into parts.
1). Product of 7 and a number 't' = 7 × t
2). 5 more than the product of 7 and a number 't' = 7t + 5
3). Five more than the product of 7 and a number t is equal to 10 ⇒ 7t + 5 = 10
Therefore, Option (B) will be the correct option.

A stock price S is governed where z is a standardized Wiener process. Find the process that governs G(t)
This question is incomplete, the complete question is;
A stock price S is governed by dS = aSdt + bSdz
where z is a standardized Wiener process. Find the process that governs G(t) = S^1/2(t)
Answer:
G = S^1/2
Step-by-step explanation:
Solving the Equation
dS = aSdt + bSdz
First we Take S common from Right hand Side
dS = S(a dt + b dz)
Then we also take S Left Hand Side(LHS) from RHS
dS/S = a dt + b dz
So d = a dt + b dz
now we Take d Common from RHS
d = d(a t + b z)
So
d/d = a t + b z
1 = a t + b z
So, t = (1-b z) / a
Now substitute value of t in equation G(t) = S^1/2(t)
we have
G{(1- b z)/a} = S^1/2 {(1- b z)/a}
(1- b z)/a) from both sides cancels out each other
So we have G = S^1/2

New heat lamps are reported to have the mean lifespan of 100 hours with a standard deviation of 15 hours. Before replacing their current lamp to the new heat lamps for the university, OSU decided to test whether the mean lifetime is equal to 100 or not by sampling 36 heat lamps. They turned them on and recorded the time, in hours, until each lamp failed. The sample provided a mean lifespan is 105.1 hours.
1) What set of hypotheses are correct for this problem?
SET 1 - H0: µ = 100 hours , Ha: µ < 100 hours
SET 2 - H0: µ = 100 hours , Ha: µ > 100 hours
SET 3 - H0: µ = 100 hours , Ha: µ ≠ 100 hours
A) SET 1.
B) SET 2.
C) SET 3.
2) If we assume the null hypothesis to be true, the average of the distribution of sample means, μ x ¯, from a sample size of 36 is:______.
a) 15.
b) 115.
c) 100.
d) 105.1. .
3) According to the Central Limit Theorem, the standard deviation of the distribution of the sample means is:______.
a) 115.
b) 15.
c) 6.
d) 2.5. .
4) What is the approximate probability of observing a sample mean of 105.1 or more from the distribution of sample means, again assuming that the null hypothesis is true?
a) 0.68.
b) 0.025.
c) 0.975.
d) 0.16.
Answer:
1
The correct option is C
2
The correct option is C
3
The correct option is A
4
The correct option is B
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 100[/tex]
The standard deviation is [tex]\sigma = 15[/tex]
The sample size is [tex]n = 36[/tex]
The sample mean is [tex]\= x = 105.1[/tex]
Generally
The null hypothesis is [tex]H_o: \mu = 100 \ hours[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 100\ hours[/tex]
Given that the null hypothesis is true then the distribution of sample means [tex]\mu_{\= x }[/tex], from a sample size of 36 is mathematically represented as
[tex]\mu_{\= x } = \mu[/tex]
=> [tex]\mu_{\= x } = 100[/tex]
According to the Central Limit Theorem the test stated in the question is approximately normally distributed if the sample size is sufficiently large[tex](n > 30 )[/tex] so given that the sample size is large n = 36
Then the test is normally distributed and hence the standard deviation is 15
Generally the standard error of mean is mathematically represented as
[tex]\sigma_{\= x } = \frac{ \sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x } = \frac{15}{\sqrt{36} }[/tex]
=> [tex]\sigma_{\= x } = 2.5[/tex]
Generally the approximate probability of observing a sample mean of 105.1 or more is mathematically represented as
[tex]P( \= X \ge 105.1 ) =1 - P(\= X < 105.1) = 1- P(\frac{\= X - \mu }{\sigma_{\= x }} <\frac{105.1 - 100}{2.5} )[/tex]
=> [tex]P( \= X \ge 105.1 ) =1 - P(\= X < 105.1) = 1- P(Z<2.04 )[/tex]
From the z-table (reference calculator dot net )
[tex]P(Z<2.04 ) = 0.97932[/tex]
So
[tex]P( \= X \ge 105.1 )= 1 - P(\= X < 105.1) = 1- 0.97932[/tex]
[tex]P( \= X \ge 105.1 ) =0.02[/tex]

Answer:
27 trees needs to be in the orchard.
Step-by-step explanation:
amber needs to harvest at least 2293 of plums to cover the cost of running the orchard.
but also wants to donate 280 plums.
each tree produces an average of 83 plums
find: how many plums of trees needed to be in the orchard?
number of trees required = total harvest / number of plums produced per tree
therefore,
number of trees required = 2293 / 83 ≅ 27 trees needs to be in the orchard.
so Amber can donate 280 plums to charity.

what is the probability that a randomly selected driver fatality who was female was 55 to 69 years old
Answer:
0.1354
Step-by-step explanation:
Relevant data provided as per the requirement is shown below:-
Female probability of age between 55 to 69 = 2058
Male probability of age between 55 to 69 = 4571
According to the given situation, the calculation of probability is shown below:-
[tex]= \frac{Female\ from\ 55\ to\ 69 }{Total\ female}[/tex]
where,
Total female is
= 143 + 2333 + 4027 + 5178 + 2058 + 1459
= 15,198
And, the female is 2058
So, the probability is
[tex]= \frac{2058}{15,198}[/tex]
= 0.1354
Therefore for computing the probability of female that lies between 55 to 69 we simply applied the above formula.

Please help me solve this 166=-w+66
Answer:
w = -100
Step-by-step explanation:
Step 1: Write out equation
166 = -w + 66
Step 2: Subtract 66 on both sides
100 = -w
Step 3: Divide both sides by -1
w = -100
Answer:
w=-100
Step-by-step explanation:
We are given the equation:
166= -w +66
To solve for x, we must get x by itself on one side of the equation.
66 is being added to -w. The inverse of addition is subtraction. Subtract 66 from both sides of the equation.
166-66= -w+66-66
166-66= -w
100= -w
-1 and w are being multiplied. The invers of multiplication is division. Divide both sides of the equation by -1.
100/-1= -w/-1
100/-1=w
-100=w
Let's check our solution. Plug -100 in for w.
166= -w+66
166= -(-100)+66
166=100+66
166=166
The statement above is true, so we know our solution is correct.
The solution to 166= -w+66 is w= -100
Limes are on sale. That sale price is 8 limes for $2.00. Why could the unit rate be 4 or 0.25?
Answer:
C.No, because each lime will cost a bit more than 30¢, so 4 limes will cost a bit more than $1.20.Step-by-step explanation:
The unit price of the 8 limes is $0.25 per lime.
The given expression:
The selling price for 8 limes = $2.00
To find:
if the unit price is $4 or $0.25The unit price of the lime is calculated by dividing the total selling price by the total number of limes purchased.
[tex]unit \ price = \frac{total \ amount \ paid \ for \ 8 \ limes }{8 \ limes } \\\\unit \ price =\frac{\$ \ 2}{8 \ limes } \\\\unit \ price = (\frac{1}{4} ) \frac{\$}{lime} \\\\unit \ price = \$0.25 \ per \ lime[/tex]
Thus, the unit price of the 8 limes is $0.25 per lime.

4(x - 3) = 4(2x + 1)
Hi there! :)
Answer:
[tex]\huge\boxed{x = -4}[/tex]
4(x - 3) = 4(2x + 1)
Distribute the coefficient outside of the parenthesis:
4(x)+ 4(-3) = 4(2x) + 4(1)
Simplify:
4x - 12 = 8x + 4
Subtract 4x from both sides:

I need help with the following question, whichever one is right will get brainliest!
Given: m∠A + m∠B = 90° (Definition of Complementary Angles).
Given: m∠B = (5x + 8)°
A) m∠A = 180° + (5x + 8) is your answer choice:
Why it isn't the others:
B) m∠A = 90° - (5x + 8)
You are solving for complementary angles (90° in total when combined), so you subtract the measurement for B (5x + 8) to get A.
C) m∠A = 180° - 2(5x + 8)°
You double the complementary angle to solve for the supplementary. Essentially, just divide this answer by two to get the complementary angles.
D) m∠A = 82 - 5x
I was confused by this one, but essentially they just did one step of the isolating the variable, which was subtracting 8 from both sides. They did not finish isolating the variable however.
