Step-by-step explanation:

Area of circle = 2πr²

diameter = 14 cm

so,

after inserting values in the formula we got,

2 × 22/7 × 14

→ 2 × 22 × 2 = 44 × 2 = 88 cm²

hence, area of the circle is 88cm²

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.

(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.

Answer:

a = xab/(b + c)

Step-by-step explanation:

x = (a + b + c)/ab

Isolate the variable by multiplying/dividing everything, but variable a to both sides

x × ab/(b+ c) = (a + b + c)/ab × ab/(b + c)

xab/(b + c) = a

Answer: 9m

Step-by-step explanation:

Answer: 9m

Step-by-step explanation:

The expression that is equal to E is C) Q − RW. When Q is divided by W, the quotient (R) is the result of the division, and the remainder (E) is the leftover value.

We have, When Q is divided by W, the quotient is R and the remainder is E.

From this, we can write the equation

Q = W × R + E

The given equation can also be written as

Q = RW + E

By solving for E, we get

E = Q - RW

Now let us check the given options

A) RW + Q

B) RW - Q

C) Q - RW

D) QW - RE) Q/RW

The correct option that is equal to E is Q - RW. Hence the correct answer is an option (C).

After choosing every proportion, if 24 people have the flu out of 360 people, then 60 people would have the flu out of 900.

We know very well that if any relation of one quantity is given with the second quantity at any instant of  time and same relation question is asking  at another instant of time, then always use unitary methods.

The unitary method is defined as a technique for solving a problem by first finding the value of a single unit, and then with the help of found value the necessary value can be find by multiplying the single unit value.

Here, In 360 people number of people would have flu=24

∴In 900 people number of people would have flu=(24×900)/360

                                                                                   =21600/360

                                                                                    =60people.

Answer:

Step-by-step explanation:

To find the predicted consumption, we can plug the given values into the regression equation:

C = 193 + 0.65 GDP + 0.08 (% change in stock price)

Given:

GDP = 200

% change in stock price = -20% (or -0.2)

Substituting the values:

C = 193 + 0.65 * 200 + 0.08 * (-0.2)

C = 193 + 130 - 0.016

C = 322.984

Rounding to two decimal places, the predicted consumption, when GDP is 200 and the share market falls by 20%, is approximately 322.98.

The 90% confidence interval for the mean noise level at these airport locations is approximately (148.1, 171.9).

Step 1 of 4:

To calculate the sample mean for the given sample data, we sum all the values and divide by the sample size.

Sample mean = (162 + 176 + 162 + 141 + 159) / 5 ≈ 160.0 (rounded to one decimal place)

Step 2 of 4:

To calculate the sample standard deviation, we need to find the differences between each data point and the sample mean, square those differences, sum them up, divide by the sample size minus 1, and then take the square root.

Deviation from mean: (162 - 160)^2, (176 - 160)^2, (162 - 160)^2, (141 - 160)^2, (159 - 160)^2

Sum of squared deviations = (2^2 + 16^2 + 2^2 + (-19)^2 + (-1)^2) = 590

Sample standard deviation = sqrt(590 / (5 - 1)) ≈ 9.6 (rounded to one decimal place)

Step 3 of 4:

To find the critical value for a 90% confidence interval, we need to look up the t-value in the t-distribution table with (n-1) degrees of freedom. Here, n is the sample size, which is 5.

Degrees of freedom = 5 - 1 = 4

Looking up the t-value for a 90% confidence level and 4 degrees of freedom, we find it to be approximately 2.776 (rounded to three decimal places).

Step 4 of 4:

To construct the 90% confidence interval, we use the formula:

Confidence interval = sample mean ± (critical value * (sample standard deviation / sqrt(sample size)))

Confidence interval = 160.0 ± (2.776 * (9.6 / sqrt(5)))

Calculating this expression will give us the lower and upper bounds of the confidence interval.

Confidence interval = 160.0 ± (2.776 * 4.297) ≈ 160.0 ± 11.9 (rounded to one decimal place)

Using the sample mean, standard deviation, and critical value, we constructed a 90% confidence interval for the mean noise level, which is approximately (148.1, 171.9) decibels. This confidence interval provides an estimate of the range within which the true mean noise level at these airports is likely to fall with 90% confidence.

The equation of the line that is perpendicular to given line is y = -x -2

From the question, we are to determine the equation of the line

From the given information,

We have that the two lines are perpendicular

If two lines are perpendicular, the product of their slopes is -1

That is,

m₁m₂ = -1

Where m₁ is the slope of the first equation

and m₂ is the slope of the second equation

In the given equation,

y = x - 2

Compare to the general form of the equation of a line

y = mx + b

Where m is the slope

and b is the y-intercept

Thus,

In the equation, y = x - 2

Slope = 1

Therefore,

The slope of the equation we are to determine is -1

Also, from the given information,

The line passes through the point (-12, 10)

Using the point-slope form of a line

y - y₁ = m(x - x₁)

x₁ = -12

y₁ = 10

Thus,

y - y₁ = m(x - x₁)

y - 10 = -1(x - -12)

y - 10 = -1(x + 12)

y - 10 = -x -12

y = -x -12 + 10

y = -x -2

Hence, the equation of the line that is perpendicular to given line is y = -x -2

The probability that the mean weight of a sample of twenty freshmen will be greater than 145 pounds is 0.138.

The probability is determined using the central limit theorem and the formula for the standard error of the mean:

where;

Data given;

σ = 12.3 pounds; n = 20

SE = 12.3/√20

SE = 2.75 pounds.

The sample mean is then standardized using the z-score formula:

z = (x - μ) / SE

z = (145 - 142) / 2.75

z = 1.09

Using a calculator, the probability of a z-score greater than 1.09 is 0.138.

If a null hypothesis is not rejected at a significance level of 0.05 it will sometimes at a significance level of 0.01.

The population standard deviation is unknown, and the population is assumed to be a normal distribution, the correct test statistic to use is p value.

If a null hypothesis is not rejected at a significance level of 0.05, it may or may not be rejected at a significance level of 0.01.

The decision depends on the specific results of the hypothesis test and the level of evidence available.

When the population standard deviation is unknown and the population is assumed to be normally distributed, the correct test statistic to use is the t-test.

The t-test is appropriate for small samples or when the population standard deviation is unknown.

The z-test is used when the population standard deviation is known and the sample size is large.

The r-test is not a standard test statistic, and the p-value is a statistical concept used to measure the strength of evidence against the null hypothesis, not a specific test statistic.
