Three problems would arise if the frequency of scrum was lowered to every two or three days.

(A) There may be missed opportunities to examine and amend the sprint backlog.

(B) The Sprint strategy deteriorates; barriers are raised and taken down more slowly.

(C) Too much time is spent updating the scrum board prior to meetings.

Scrum is a project management framework that was initially focused on software development, while it has now been applied to other areas such as research, sales, marketing, and cutting-edge technology.

It is intended for groups with ten or fewer members who divide their work into tasks that can be finished in sprints, which are time-boxed iterations that can be done in as little as one month and most frequently two weeks.

If the frequency was reduced to every two or three days, there would be three issues.

(A) The chances to review and modify the Sprint Backlog may be missed.

(B) The Sprint plan becomes imprecise; obstacles are raised and removed more slowly.

(C) Too much time is spent before meetings updating the scrum board.

Therefore, three problems would arise if the frequency was lowered to every two or three days.

(A) There may be missed opportunities to examine and amend the sprint backlog.

Answer:

left 4 up one because the coordinates are -4 , 1

Answer:

the first one (-4, 1)

Step-by-step explanation:

still If we plug in x = -2 into the original equation.

A logarithm is a mathematical function that helps to determine how many times a particular number must be multiplied by itself to obtain a specific value. In other words, the logarithm of a number is the exponent to which another fixed value, called the base, must be raised to produce that number.

Given by the question.

Using logarithm rules, we can simplify the left-hand side of the equation:

log2x + log2(x – 6) = log2(x (x – 6))

So, the equation becomes:

log2(x (x – 6)) = 4

Using the description of logarithms, we can rewrite this as:

\(2^{4}\) = x (x – 6)

Simplifying the left-hand side, we get:

16 = \(x^{2}\) – 6x

Moving all the terms to one side, we get a quadratic equation:

\(x^{2}\) – 6x – 16 = 0

We can break this using the quadratic formula:

x = [6 ± sqrt (\(6^{2}\)+ 4(1)(16))] / 2

x = [6 ± sqrt (100)] / 2

x = [6 ± 10] / 2

x = 8 or x = -2

The upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

To determine the upper bound of the 95% confidence interval for the average age in the U.S., we can use the sample data from the survey. The sample size is 1072 people, randomly selected from the U.S. population, with a minimum age of 12. By calculating the average age of the respondents, we can estimate the average age of the entire U.S. population.

Using the given information that the average age of the respondents is 43.56 years, and assuming that the sample is representative of the population, we can calculate the standard error. The standard error measures the variability of the sample mean and indicates how much the sample mean might deviate from the population mean.

Using statistical methods, we can calculate the standard error and construct a confidence interval around the sample mean. The upper bound of the 95% confidence interval represents the highest plausible value for the population average age based on the sample data.

The sample space for rolling a six-sided number cube is \({1, 2, 3, 4, 5, 6}\)}, representing the six possible outcomes of the experiment.

The sample space for the experiment of rolling a six-sided number cube consists of all the possible outcomes or numbers that can be obtained when the cube is rolled. Since a standard six-sided cube has six faces, each numbered from 1 to 6, the sample space can be represented as     \({1, 2, 3, 4, 5, 6}\)}.

In this case, the sample space is a set containing the individual numbers 1, 2, 3, 4, 5, and 6, which represent the possible outcomes of rolling the cube. Each number in the sample space corresponds to a face of the cube, and when the cube is rolled, one of these numbers will be the result.

It's important to note that each outcome in the sample space is equally likely, assuming the cube is fair and unbiased. Therefore, the probability of obtaining any particular outcome is 1 out of 6 or approximately 0.1667.

Answer:

The cost of renting the car for 20 days is $481

Step-by-step explanation:

The table of values can be formed as follows;

Day,   Cost

1,         $44

2,        $67

3,        $90

4,        $113

7,        $182

10,      $251

From the given values and the scatter plot, there is a straight line relationship between the cost and the number of days of rental of a car.

The line of best fit is therefore a straight line and from the constant increase in cost ($23) for each extra day of rental, it is possible to find the slope, m, of the data as follows;

\(Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

(x₁, y,) and (x₂, y₂) can be taken as (1, $44) and (3, $90) respectively to give;

\(Slope, \, m =\dfrac{90-44}{3-1} = \dfrac{46}{2} = 23 \ as \ stated \ above\)

The equation in slope and intercept form is therefore, y  - 44 = 23×(x - 1), which gives;

y - 44 = 23·x - 23

y = 23·x - 23 + 44 = 23·x + 21

The cost of renting the car for 20 days is then;

10×23 + 21 = $481

The cost of renting the car for 20 days = $481.

Step-by-step explanation:

To test the hypothesis that the mean salary for associate professors in research institutions is $2000 higher than for those in other institutions, we can perform a two-sample t-test.

The null hypothesis is that the difference in means is not significantly different from $2000, while the alternative hypothesis is that the difference is greater than $2000.

Using the given information, we can calculate the t-statistic as (70750 - 65200 - 2000) / sqrt((6000^2/200) + (5000^2/200)) = 5.39. With 398 degrees of freedom (n1 + n2 - 2), the p-value for this one-sided test is less than 0.0001.

Since this p-value is much smaller than any reasonable level of significance, we reject the null hypothesis and conclude that there is strong evidence that the mean salary for associate professors in research institutions is significantly higher than for those in other institutions by $2000.

d = -2

Step-by-step explanation:

6 (d-4) = 18d

6d - 24 = 18 d

-24 = 18d - 6d

-24 = 12d

d = -24 / 12

d = -2

To Find: Value of (d) if,

6(d - 4) = 18 d.

6(d - 4) = 18d

→ 6d - 24 = 18d

(Simplified the LHS portion)

→ 6d - 18 d = 24

(Like terms are separated)

→ - 12d = 24

→ - d = 24/12

→ - d = 2

→ d = - 2

Verification:-

LHS:-

6(d - 4)

= 6d - 24

= 6(- 2) - 24

= - 12 - 24

= - 36

RHS:-

18d

= 18(- 2)

= - 36

Thus,

LHS = RHS.

To calculate the strategy gap, operations gap, and total gap, we need to compare the expected sales targets with the actual sales achieved

The gap analysis graph would display the expected sales targets for each objective and compare them to the actual performance. The y-axis represents the sales in millions of pounds, and the x-axis represents the planning period from 2016 to 2019. Each objective's expected sales target would be plotted as a line, and the actual sales achieved would be plotted as a separate line. The gaps between the two lines would indicate the variance between expectations and performance.

To calculate the strategy gap, operations gap, and total gap, we need to compare the expected sales targets with the actual sales achieved. The strategy gap represents the variance between the target sales and the actual sales for each objective. The operations gap reflects the overall variance between the total expected sales and the actual sales achieved. Finally, the total gap would be the sum of the strategy gap and operations gap.

To formulate the corporate objective statement for Lush in 2019, we consider the net profit and total assets. Since the net profit is 10% of sales, we can calculate the net profit as 0.1 multiplied by the actual sales achieved in 2019. Given that the assets are 1000m, the corporate objective statement could be formulated as follows: "Lush aims to achieve a net profit of [calculated net profit] and maintain its total assets at 1000m in 2019, while continuing to expand its product offerings and market share."

The probability of three rooks being placed on a 3x3 chessboard without any of them being able to capture another is about 3.57%.

There are a total of 9 squares on a 3x3 chessboard, and we need to place 3 rooks on these squares. There are 9 choices for the first rook, 8 choices for the second rook, and 7 choices for the third rook.

However, not all of these choices will result in a valid configuration where none of the rooks can capture each other. To be valid, each row and each column must have at most one rook.

Let's consider the number of valid configurations. Without loss of generality, we can assume that the first rook is placed in the first row. There are 3 choices for the column of the first rook. The second rook can be placed in any of the 6 remaining squares, but only 3 of these squares are in rows or columns that do not already have a rook. Finally, the third rook can be placed in any of the 3 remaining squares, but only 2 of these squares are in rows or columns that do not already have a rook.

Therefore, the total number of valid configurations is 3 x 3 x 2 = 18.

The total number of ways to place the rooks is 9 x 8 x 7 = 504.

Therefore, the probability that none of the rooks can capture any of the other two is 18/504 = 1/28, or approximately 0.0357.

year 6 is 500 * 1.03^(6) = 597.03

Year 7 is 500 * 1.03^(7) = 614.94

Step-by-step explanation:

The amount is increasing, and there are two main ways for that to happen.  Addition and multiplication.  So let's see if it keeps getting the same amount added or multiplied.  

0 to 1 goes from 500 to 515, so 15 is added.  but 15.45 is added from 1 to 2, so we can't just do simple addition.

using multiplication 0 to 1 has 1.03 multiplied.  if you multiply by it again you do get 530.45, so we have established what is happening.  

You can use the formula 500 * 1.03^x to solve for any year.

so year 4 is 500 * 1.03^(4) = 562.75

year 6 is 500 * 1.03^(6) = 597.03

Year 7 is 500 * 1.03^(7) = 614.94

Answer:

25 girls

Step-by-step explanation:

We Know

The ratio of boys to girls is 4:5. For every 4 boys, there are 5 girls.

To get from 4 to 20, we multiply by 5.

We Take

5 x 5 = 25 girls

So, there are 25 girls in class.

Answer: 25 girls are in the class

Step-by-step explanation: You can set up the ratio 4:5 as a fraction, \(\frac{4}{5}\) to find your answer. You are given the fact that 20 boys are in the class so now you can solve 2 ways.

Option 1 - Set up the equation algebraically as \(\frac{20}{x}\), where x = number of girls and set that equal to \(\frac{4}{5}\). This way allows you to see that the fraction must have the same ratio as 4:5. You can see that 4 x 5 = 20, so the multiple factor is 5. The variable x must equal 5 x 5, so x = 25.

Option 2 - Multiply the amount of boys given to you by the reciprocal of the ratio. Instead of using \(\frac{4}{5}\), you have to use \(\frac{5}{4}\) because there are more girls than boys in the class. This allows you to finish the problem by multiplying 20 x \(\frac{5}{4}\) to get the result of \(\frac{100}{4}\), which you may know simplifies into 25.

The required surface area of the sphere with radius 10 feet is given by option a. 1,256 ft².

Let us consider 'r' be the radius of the sphere.

Radius of the sphere 'r' = 10 feet

Surface area of the sphere = 4 π r²

Substitute the value of radius in the formula we get,

⇒ Surface area of the sphere = 4 π × ( 10 )²

Substitute value of π is equal to 3.14 we get

⇒ Surface area of the sphere = 4 × 3.14 × ( 10 )²

⇒ Surface area of the sphere =  12.56 × 100

⇒ Surface area of the sphere = 1,256 square feet.
