The amount of time required for an assembly line worker to complete a repetitive task is measured using a time and motion study.

According to the data, the average time it takes to move apart from the bin to its place on a car's chassis is 11 seconds, while the standard deviation is 2 seconds.

If XX and YY are independent, the property mean and variance are as follows: X 1 = 11; sigma_X_1 = 2, X 1 = 2, mu_X_2 = 20, X 2 = 20, sigma_X_2 = 4, and X 2 = 4.

aX+bY = a X + b Y; sigma_aX+bY = a X + b Y; aX+bY 2 = a 2 X 2 + b 2 Y 2; and finally, we have the following results:

X 1 + X 2 = X 1 + X 2 = 11+20=31 sigma_X_1+X_2=sqrtsigma_X_1+sigma_X_2=sqrtsigma_X_1+sigma_X_2=sqrtsigma_X_2=sqrtsigma_X_2=sqrtsigma_X_2=sqrtsigma_X_1+

The value reduced by the mean and divided by the standard deviation is the z-score:

z=\dfrac{x-\mu} {\sigma} =\dfrac{30-4.4721} \approx - 0.22

When solving a word problem using a system of equations with two unknowns, you must create two equations. So, correct option is B.

The reason is that each unknown in the problem requires an equation to represent its relationship with the other variables.

For example, let's say you have two unknowns, x and y. You need two equations to define the relationships between these variables. These equations can be represented as:

Equation 1: x + y = 10 (This equation represents the relationship between x and y based on the given information in the problem.)

Equation 2: 2x - y = 4 (This equation represents another relationship between x and y based on additional information provided in the problem.)

With a system of two equations involving two unknowns, you can use algebraic methods such as substitution or elimination to solve for the values of x and y.

Having only one equation would not be enough to determine unique values for both x and y, as there would be an infinite number of possible solutions. On the other hand, having more than two equations might lead to over-determining the system, making it inconsistent or redundant.

Therefore, two equations are the minimum required to solve for two unknowns effectively. So, correct option is B.

Conner and Darian each gave their dad $25.00, which means they gave a total of $25.00 * 2 = $<<25*2=50.00>>50.00 to their dads.

This means that Conner and Darian had $29,971.25 - $50.00 = $29,921.25 left to invest in their hot chocolate shop.

The percentage increase is about 16.66%.

What is a percentage increase?

The percentage increase formula is the ratio of value increased to the original value and multiplied by 100. It is expressed in percentage. If there is an increase in the value of anything, then there is an increase in the percentage.

The initial amount was $18 and the final amount is $21.60.

By using the percentage increase formula, we can write

        Percentage increase = (final value - initial value)/|Final value| * 100

                                            = ((21.60 - 18)/21.60)*100

                                            = 16.66%

Length of each Plan A workout: 4 hours and Length of each Plan B workout: 8 hours.

To find the length of each workout plan, we need to know the total amount of time that Deshaun spent on each plan. We can find this by adding up the number of clients who did each plan on Friday and Saturday and then multiplying by the total amount of time that Deshaun spent training his clients on each day.

On Friday, Deshaun had 4 clients who did Plan A and 8 who did Plan B, for a total of 4 + 8 = 12 clients.

On Saturday, Deshaun had 2 clients who did Plan A and 3 who did Plan B, for a total of 2 + 3 = 5 clients.

In total, Deshaun had 12 + 5 = 17 clients who did his workout plans.

Since Deshaun trained his Friday clients for a total of 17 hours and his Saturday clients for a total of 7 hours, the total amount of time that he spent on Plan A was 4 × 17 = 68 hours.

The total amount of time that he spent on Plan B was 8 × 17 = 136 hours.

Since there were 17 clients in total, the length of each Plan A workout is 68 / 17 = 4 hours.

The length of each Plan B workout is 136 / 17 = 8 hours.

Thus, the length of each Plan A workout is 4 hours, and the length of each Plan B workout is 8 hours.

Multiplication in the context of integers or counting numbers is just repeated addition. Consequently, 3 x 5 equals:

5 is added to 0 and placed in the "accumulator."

For a total of three times, repeat operation (1).

As a/b times c/d = ac/bd, we can simply extend multiplication to rational integers. By the way, this definition enables us to say that multiplication is closed for rational numbers.

Concentrating on the words "sum" and "product" in relation to "things that aren't numbers" is still beneficial. In logic, the terms "sum" and "product" have a non-numerical sense as the union and intersection of sets.

For instance, a "blue circle" is a reasonable outcome. It is where the "blue" and "circle" sets cross. The only components in the logical combination of the two sets would be those that are "blue" or "circular."

The true statement about the graph include:

1. The y-intercept represents the orders for hot chocolate on a day when the outside temperature was 52°F.

2. Sheryl gets 160 orders for hot chocolate on a day when the outside temperature is 52°F.

It is clearly mentioned on graph above 52 degrees fahrenheit. So y-intercept represents the orders for hot chocolate when the outside temparature was 52 F.

For every 16° increase in temparature above 52°F there is a decrease of 32 orders. Therefore for each degree increase above 52°F decrease in order = 32/16 => 2

So Sheryl gets 2 few orders for each degree decrease in temperature above 52°F. The slope of the line represents the decrease in numbers of order per degree increase in temparature.

2) The variable cost (slope) for each person on board the bus is $2.

3) An equation to show the cost, c, of a bus with x number of people on it is C = 120 + 2x.

The total charge for taking 30 people aboard = $180

The total charge for taking 50 people on board = $220

The differences in the number of people and charges are 20 and $40, respectively.

Let x = the number of people boarding the bus and n = the fixed rate per bus.

30x + n = 180 ... Equation 1

50x + n = $220  ... Equation 2

Subtract Equation 1 from Equation 2:

20x = $40

x = $2 ($40/20)

The variable cost per person = $2 ($40/20)

The base rate for the empty bus = 30(2) + n = $180, where n is the base rate or fixed cost per bus.

The correct answer is D. A 95% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the population proportion.

The width of a confidence interval reflects the degree of uncertainty about the estimate of the population parameter. A wider interval indicates a higher degree of uncertainty, while a narrower interval indicates a lower degree of uncertainty.

The confidence level of a confidence interval is the probability that the interval contains the true population parameter. For example, a 95% confidence interval means that there is a 95% probability that the interval contains the true population parameter. Similarly, an 80% confidence interval means that there is an 80% probability that the interval contains the true population parameter

Since a 95% confidence interval is more confident that it captures the true value of the population parameter than an 80% confidence interval, the 95% confidence interval must be wider in order to capture the true value with a higher degree of confidence.

Answer:

To create a proportion using the form %/100 = is/of, we can first write the given information in the form %/100 = is/of. In this case, we know that 1 1/2% represents 15, so we can write:

1 1/2%/100 = 15/of

Next, we need to solve for the "of" value, which is the number we are trying to find. To do this, we can multiply both sides of the equation by 100 and then divide both sides by 1 1/2% to get:

(1 1/2%/100) * 100 = (15/of) * 100

of = (15/1 1/2%) * 100

Finally, we can evaluate the right-hand side of the equation to find the value of "of". Since 1 1/2% is the same as 1.5%, we can substitute 1.5 for 1 1/2% in the equation to get:

of = (15/1.5%) * 100

of = (15/0.015) * 100

of = 1000

Therefore, the number we are trying to find is 1000.

In summary, the proportion that represents the given word problem is:

Let the unknown number be x.

Therefore:

Substitute these into the proportion formula to create a proportion to represent the given word problem:
