Answer:
To find the total direct cost of one item, we need to calculate the sum of the direct labor cost and the direct material cost.
Direct labor cost per item = (hourly rate)/(number of items per hour) = $20/160 = $0.125 per item
Direct material cost per item = $0.50 per item
Total direct cost per item = direct labor cost per item + direct material cost per item
= $0.125 + $0.50 = $0.625
Therefore, the total direct cost of one item is $0.625.

A sample of maximum pressure from 12 trials with a stamping machine yielded a mean of 7.2 thousand psi and a standard deviation of 1.2 thousand psi. The histogram of the sample data is approximately normal. Calculate a 90% confidence interval.
The 90% confidence interval for the mean pressure is calculated equivalent to (6.39, 7.99).
What is t-distribution table?A t-distribution table is a statistical table that lists critical values of the t-distribution for various levels of significance and degrees of freedom. The t-distribution is a probability distribution that is used when the sample size is small or when the population standard deviation is unknown.
The table is organized by degrees of freedom (df), which is calculated as n-1, where n is the sample size. It also lists different levels of significance, usually ranging from 0.01 to 0.5 or more. The critical values are listed in the table corresponding to the degrees of freedom and the significance level. To use a t-distribution table, you need to know the degrees of freedom and the level of significance.
To calculate the 90% confidence interval for the mean pressure, we can use the formula:
CI = X' ± Z*(σ/√n)
Where X' is the sample mean, σ is the sample standard deviation, n is the sample size, and Z is the critical value for a 90% confidence interval.
Since the sample size is 12, we need to use a t-distribution with 11 degrees of freedom to find the critical value, because we are estimating the population standard deviation from the sample. Using a t-distribution table or calculator, we can find that the critical value for a 90% confidence interval with 11 degrees of freedom is approximately 1.796.
Substituting the values into the formula, we get:
CI = 7.2 ± 1.796*(1.2/√12)
= 7.2 ± 0.81
Therefore, the 90% confidence interval for the mean pressure is:
(7.2 - 0.81, 7.2 + 0.81) or (6.39, 7.99)
So, we can say with 90% confidence that the true mean pressure of the machine lies between 6.39 thousand psi and 7.99 thousand psi.

A 1,000 g
B 2,300 g
C 3,000 g
D 300 g
By answering the presented question, we may conclude that As a result, inequality the correct answer is D) 300 g.
What is inequality?In mathematics, an inequality is a statement that compares two values or expressions and shows the relationship between them, usually using the symbols > (greater than), < (less than), ≥ (greater than or equal to), or ≤ (less than or equal to).
For example, "3 > 2" is an inequality that states that 3 is greater than 2. Similarly, "x ≤ 5" is an inequality that states that the value of x is less than or equal to 5.
Inequalities are used to represent ranges of possible values and are commonly used in algebra, calculus, and other branches of mathematics. They are often used to describe constraints in optimization problems, such as finding the maximum or minimum of a function subject to certain conditions.
To begin, we must convert the weights to the same units. We can convert rabbit weight to grammes as follows:
300 grammes = 0.3 kilos
We can also convert duck weight to grammes:
700 grammes = 0.7 kilos
We can now multiply the weights of rabbits and ducks:
300 grammes plus 700 grammes equals 1000 grammes
300 grammes plus 1300 grammes plus 700 grammes equals 2300 grammes.
To calculate how many more grammes of pellets Al feeds the chickens than the rabbits and ducks combined, subtract the total weight of pellets fed to the rabbits and ducks from the weight of pellets fed to the chickens:
1300 grammes minus 1000 grammes equals 300 grammes
As a result, the correct answer is D) 300 g.

A 500g packet of beans costs £1.55
A 125g packet of the same beans costs £0.36
Which packet is better value for money?
The packet is better value for money is a 125 g packet of beans which costs £0.36.
The better value for money of packet of beans can be calculated as follows?The first step we can check on the first packet value for money by calculating the costs of 1 g of beans as follows :
[tex](1/500) \times \£1.55 = \£0,003[/tex]
The second step we can check on the second packet value for money by calculating the costs of 1 g of beans as follows :

Hence, the better value for money between those two packet of beans is the second packet of beans which given by 125 g and costs £0.36.
Answer:
125g
Step-by-step explanation:
Find 1g of beans for both packets
500g /500 = 1
£1.55 / 500 = £0.0031 per gram
125 / 125 = 1
£0.36 / 125 = £0.00288 per gram

"The set of 24, 25, 26, and 28 has a mean of 30." b. "15 is the median of this data set: 12, 14, 15, 13, and 16."
The first statement about mean is false.
The second statement about median is false.
What is mean and median?
The "mean" is the "average" of any data set. Sum of all the data and dividing that by the number of data will give the mean.
The "median" is the "middle" value in the given list of data.
At the first statement the values are 24,25,26,28.
Now the smallest value is 24 and the greatest value is 28. so the average or mean must be in between 24 and 28. It cant exceeds the value 28.
Here given that mean is 30 which is obviously greater than 28. So it cant be the mean of the given data set.
At the second statement the data are 12,14,15,13,16.
The listed values are not in ascending order Without making the values in ascending order we cant find the median. Now if we arrange the values in ascending order the list will be 12,13,14,15,16.
As there are 5 terms so there are odd number of terms. For that the median must be the middle value which is 14.
But here median is 15.
So it cant be the median of the data.

What is triangle?A triangle is a closed geometric shape that has three sides, three angles, and three vertices (or corners). It is one of the most basic and important shapes in geometry. The sum of the angles in a triangle is always 180 degrees, and the length of each side can be calculated using the Pythagorean theorem or other geometric formulas. Triangles can be classified into different types based on the length of their sides and the size of their angles, such as equilateral, isosceles, scalene, acute, obtuse, and right triangles. Triangles are used extensively in mathematics, science, engineering, and many other fields.
To find the measure of angle P, we can use the Pythagorean theorem and trigonometric functions. Here's the step-by-step solution:
From the given information, we know that one angle of the triangle is 90 degrees, and the lengths of the adjacent sides are 5 and 13.
Using the Pythagorean theorem, we can find the length of the hypotenuse:
c^2 = a^2 + b^2
c^2 = 5^2 + 13^2
c^2 = 194
c = sqrt(194)
c ≈ 13.93
So the length of the hypotenuse is approximately 13.93 units.
Now, we can use the trigonometric function sine to find the measure of angle P:
[tex]sin(P) = opposite / hypotenuse[/tex]
[tex]sin(P) = 5 / 13.93[/tex]
[tex]P = sin^{-1(5/13.93)}[/tex]
P ≈ 22.62 degrees

FIND THE SIZE OF XYZ
The angle of XYZ is approximately 87.6 degrees.
To find the angle of XYZ, you need to use the Law of Cosines, which states that c² = a² + b² - 2ab cos(C), where c is the side opposite the angle C. Given the side lengths of the triangle XYZ, you can find the measure of angle XYZ as follows:
First, use the Pythagorean Theorem to find the length of side XY: XY² = 5² + 12² = 169, so XY = √169 = 13.
Next, use the Law of Cosines to find the measure of angle YXZ: 13² = 7² + 8² - 2(7)(8)cos(YXZ), which simplifies to 169 = 113 - 112cos(YXZ). Solving for cos(YXZ), you get cos(YXZ) = (113 - 169) / (278) = -0.125.
Finally, take the inverse cosine (cos⁻¹) of -0.125 to find the measure of angle YXZ in degrees: YXZ ≈ 102.4°.
Therefore, the measure of angle XYZ is 180° - 90° - 102.4° = 87.6°.

Mr. Apo Man borrowed K 2 000 from a bank to finance an extension to his home. He agrees to pay back the loan in 8 yearly payments at 14% p.a. compound interest. a) What is the amount of each yearly payment? (2 marks)
If he agrees to pay back the loan in 8 yearly payments at 14% p.a. compound interest. The amount of each yearly payment is K 368.51.
How to find the yearly payment?To calculate the amount of each yearly payment, we can use the formula for the present value of an annuity:
PV = A * [(1 - (1 + r)^-n) / r]
where:
PV = present value of the loan
A = annual payment
r = interest rate per year
n = number of years of the annuity
In this case, Mr. Apo Man borrowed K 2 000 from the bank at an interest rate of 14% p.a. compound interest, and agreed to pay back the loan in 8 yearly payments.
So, we have:
r = 14% = 0.14
n = 8
PV = K 2 000
We can solve for A by rearranging the formula:
A = PV * r / [(1 - (1 + r)^-n)]
Substituting the values, we get:
A = K 2 000 * 0.14 / [(1 - (1 + 0.14)^-8)]
A = K 2 000 * 0.14 / 0.7598
A = K 368.51
Therefore, the amount of each yearly payment that Mr. Apo Man needs to make to repay the loan in 8 years at 14% p.a. compound interest is K 368.51.

the final velocity is approximately 14.5 meters per second.
Define accelerationThe rate at which an object's velocity alters over time is known as acceleration. It is a vector quantity, which means it has both magnitude (a numerical value) and direction.
Using the formula: v² = u2 + 2as
We can plug in the values given:
u = 6 m/s (initial velocity)
a = 3 m/s² (acceleration)
s = 29 m (distance)
v² = (6 m/s)² + 2(3 m/s²)(29 m)
v² = 36 m²/s² + 174 m²/s²
v²= 210 m²/s²
To solve for v, we need to take the square root of both sides of the equation:
v = √(210 m²/s²)
