An assembly line has 16 hours to make 1.000 units. What is the required cycle time? (slide 23) 72sec 216sec 57.65sec 14,4sec
The required cycle-time is approximately 57.6 seconds.
To find the required cycle time, we need to divide the total available time by the number of units to be produced.
Total available time: 16 hours = 16 * 60 minutes = 960 minutes = 960 * 60 seconds = 57,600 seconds
Number of units to be produced: 1,000 units
Required cycle time: Total available time / Number of units
Cycle time = 57,600 seconds / 1,000 units
Cycle time ≈ 57.6 seconds
Therefore, the required cycle time is approximately 57.6 seconds.

One day Mr. Flores had a customer come in and purchase 7 Bongo drums and 2 Tubas. His total was
$1,986. That same day he had another customer come
in and purchase 2 Bongos and 2 Tuba and his total
was $996.00. HINT: Let b=cost of bongo drums and
t= cost of a tuba.
Step-by-step explanation:
The equations are,
7b + 2t = 1986 -----> 1
2b + 2t = 996 -----> 2
From 1,
2t = 1986 - 7b
Using 2t value in 2,
2b + 1986 - 7b = 996
-5b = 996-1986 = -990
Divide by -5,
b = $198
Use the value of b in 2t,
2t = 1986 - 7*198
2t = 1986 - 1386
2t = 600
Divide by 2,
t = $300
9. Look at some of the printed letters in a textbook. The small horizontal
and vertical segments attached to the ends of the letters are called
serifs. Most of the letters in a textbook are in a serif typeface. The
letters on this page do not have serifs, so these letters are in a sans-
serif typeface. (Sans means "without" in French.) The figure shows a
capital letter A with serifs. Use the given information to write a
paragraph proof that the serif, segment HI, is parallel to segment JK.
Given: 21 and 23 are supplementary.
Prove: HI || JK
By considering the given information that angles 21 and 23 are supplementary and analyzing the properties of supplementary angles and parallel lines, we have proven that segment HI is parallel to segment JK.
To prove that segment HI is parallel to segment JK based on the given information that angles 21 and 23 are supplementary, we can utilize the properties of supplementary angles and parallel lines.
First, let's examine the given figure and information.
We have a capital letter A with serifs, where segment HI represents one of the serifs, and segment JK represents a horizontal line within the letter A.
To begin the proof, we'll make use of the fact that angles 21 and 23 are supplementary.
Supplementary angles are defined as two angles whose measures sum up to 180 degrees.
We can observe that angle 21 is an interior angle of triangle AHI, and angle 23 is an interior angle of triangle AJK.
Since angles 21 and 23 are supplementary, their sum is equal to 180 degrees.
Now, let's assume that segments HI and JK are not parallel.
In this case, if we extend lines HA and JA, they will eventually intersect at point P.
Since the angles formed at the point of intersection are supplementary (angle 21 + angle 23 = 180 degrees), it would imply that angle 21 and angle PJK, as well as angle 23 and angle PHI, are also supplementary.
However, this leads to a contradiction. In the original figure, we can observe that angle 21 and angle PJK do not form a supplementary pair since angle PJK is a right angle (90 degrees) in the letter A.
Therefore, our assumption that segments HI and JK are not parallel must be incorrect.
Consequently, we can conclude that segment HI is indeed parallel to segment JK.

salik: we need two quantitative variables for this project. wouldn’t number of siblings be categorical since it is whole numbers?
Salik and Maya are discussing a project that examines the relationship between the number of siblings someone has and their household income. Maya predicts that those with more siblings will have a higher household income. Salik questions whether the number of siblings is a categorical variable since it is a whole number. Our response can be : "In order to conduct this project, we need to choose two quantitative variables, which are variables that can be measured and expressed as numbers. The number of siblings is not a categorical variable because it is a continuous variable that can take on any whole number value."
The number of siblings is a quantitative variable because it can be expressed as a whole number. Household income is also a quantitative variable because it can be measured and expressed as a numerical value. Categorical variables are variables that can be divided into distinct categories or groups, such as gender, race, or occupation. The number of siblings is not a categorical variable because it is a continuous variable that can take on any whole number value.
To examine the relationship between the number of siblings and household income, Maya and Salik could use statistics to analyze their data. They could calculate descriptive statistics such as the mean and standard deviation for each variable, as well as the correlation coefficient to determine the strength and direction of the relationship between the two variables. They could also use probability theory to make predictions about the likelihood of certain outcomes, such as the probability that someone with more siblings will have a higher household income.

The probability of x being equal o 19.62 is d) 0.
It is given that x is normally distributed with a mean of 12 and a standard deviation of 3.
Now, Normal distribution is a continuous distribution.
This implies that the probability is measured over an interval, taking an infinite number of points in between.
If we plot a continuous distribution, the probability here at a point is not the value of the y coordinate at that point. Instead, it is seen as an area under the curve of the distribution, between the two intervals, say a and b.
Therefore, if we take up a single point say c, then the probability will be the area under the curve from c to c, which will obviously be 0.
Hence, the probability that x = 19.62 will be 0.

A wagon is pulled horizontally by exerting a force of 10 pounds on the handle at an angle of 60 with the horizontal. How much work is done in moving the wagon 50 feet
To calculate the work done in moving the wagon, we can use the formula:
Work = Force * Distance * cos(θ)
Where:
Work is the amount of work done (in foot-pounds)
Force is the applied force (in pounds)
Distance is the distance moved (in feet)
θ is the angle between the applied force and the direction of motion (in degrees)
In this case, the applied force is 10 pounds, the distance moved is 50 feet, and the angle θ is 60 degrees.
Let's calculate the work done:
Work = 10 pounds * 50 feet * cos(60°)
First, we need to convert the angle from degrees to radians:
θ (in radians) = 60° * π/180 = π/3 radians
Now, we can calculate the work done:
Work = 10 pounds * 50 feet * cos(π/3)
= 10 * 50 * cos(π/3)
= 500 * (1/2)
= 250 foot-pounds
Therefore, the work done in moving the wagon 50 feet is 250 foot-pounds.

A video rental store charges a $20 membership fee and $2.50 for each video rented.
Write a linear equation to model this situation.
Tell what each variable represents.
Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.

Assume that you have $50,000. How much would you have after 3 years if you leave it invested at 7% interest rate with annual compounding? [Hint: getFV]
After 3 years of investment at an interest rate of 7% with annual compounding, you would have a total of $61,252.14.
To calculate the amount, you would have after 3 years, with an initial investment of $50,000 at 7% interest rate with annual compounding, we can use the compound interest formula.
The formula for compound interest is given by;
FV = PV × (1 + r) n
where, FV = Future value
PV = Present value
R = rate of interest
n = number of compounding periods
For the given problem;
PV = $50,000
r = 7% = 0.07
n = 3 (as interest is compounded annually)
Now substituting these values in the formula,
FV = $50,000 x (1 + 0.07) ³
FV = $50,000 x 1.225043
FV = $61,252.14
Therefore, after 3 years of investment at an interest rate of 7% with annual compounding, you would have a total of $61,252.14.
This is obtained by adding the interest earned on the principal amount of $50,000 for 3 years.

Hector's goal is to reach a 10-kilometer run, and he plans to increase his distance by 0.5 kilometers every Saturday. By analyzing Hector's calculations, we can determine that the equation equivalent to his calculations is 2.5 + 0.5x = 10, where x represents the number of weeks. Using this equation, we can find the number of weeks it will take Hector to reach his goal of a 10-kilometer run, which is 14 weeks.
Hector's calculations show a pattern of adding 0.5 kilometers to his distance each week. We can express this pattern using the equation 2.5 + 0.5x = 10, where x represents the number of weeks. The left side of the equation represents Hector's total distance covered, while the right side represents his goal of running 10 kilometers.
To find the number of weeks it will take Hector to reach his goal, we solve the equation for x. Rearranging the equation, we have:
0.5x = 10 - 2.5
0.5x = 7.5
Dividing both sides of the equation by 0.5:
x = 7.5 / 0.5
x = 15
Therefore, it will take Hector 15 weeks to reach a 10-kilometer run.

The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is 333 to 444. If a liter of cow milk has 156015601560 international units (\text{IU})(IU)left parenthesis, start text, I, U, end text, right parenthesis of vitamin A, how many \text{IU}IUstart text, I, U, end text of vitamin A are in a liter of goat milk?
Answer:
\(Goat = 2080IU\)
Step-by-step explanation:
Given
Ratio = 3 : 4
Litre of cow = 1560IU
Required
IU of a litre of goat
The ratio represents ratio of cow milk to goat milk
In other words;
\(Cow:Goat = 3 : 4\)
To calculate the number of IU in a litre of goat milk; we substitute Cow with 1650 in the above expression
\(Cow:Goat = 3 : 4\)
\(1560:Goat = 3 : 4\)
Convert to fraction
\(\frac{1560}{Goat} = \frac{3}{4}\)
Multiply both sides by 4
\(4 * \frac{1560}{Goat} = \frac{3}{4} * 4\)
\(\frac{4 * 1560}{Goat} = \frac{ 4 * 3}{4}\)
\(\frac{6240}{Goat} = 3\)
Multiply both sides by Goat
\(Goat * \frac{6240}{Goat} = 3 * Goat\)
\(6240 = 3 * Goat\)
Divide both sides by 3
\(\frac{6240}{3} = \frac{3 * Goat}{3}\)
\(\frac{6240}{3} = \frac{3 * Goat}{3}\)
\(2080 = Goat\)
\(Goat = 2080\)
