The length of the base of the triangle is 11.5 millimeters.

The formula for the area of a triangle is:

A = 1/2 * b * h

where A is the area, b is the base, and h is the height.

We are given that the area of the triangle is 69 square millimeters and the height is 12 millimeters. Substituting these values into the formula, we get:

69 = 1/2 * b * 12

Multiplying both sides by 2 and dividing by 12, we get:

b = 11.5

The Result of the research done by the dermatologists is Option (b): The researcher has statistical evidence to conclude that the sample mean shower length for high school students is greater than 10 minutes.

Statistical hypothesis testing involves testing hypotheticals about a population grounded on a sample of data and determining whether those hypotheticals are statistically significant or simply passed by chance. The selection of a significance position is a pivotal part of this process, as it represents the probability of rejecting the null hypothesis when it's actually true.

In the given problem, dermatologists carried out a study to determine whether the average shower length of high academy scholars exceeded 10 minutes. The null hypothesis( H ₀) assumes that the population mean shower length equals 10 minutes, while the Indispensable hypothesis      ( H ₁) assumes that the population mean shower length is lesser than 10 twinkles. The experimenters named a arbitrary sample of 125 high academy scholars and set up that the average shower length was14.7 twinkles.

The p- value provides a measure of the substantiation against the null thesis. In this case, a p- value of0.0000 suggests that the liability of observing an average shower length of 14.7 minutes or further, assuming the null thesis is true, is extremely low. The significance position( α) was set at 0.05, indicating that the experimenters were willing to reject the null hypothesis if the liability of observing an average shower length of 14.7 minutes or lesser was lower than or equal to0.05.

Grounded on the p- value and significance position, the experimenters have statistical substantiation to reject the null thesis and accept the indispensable thesis. therefore, it's applicable to conclude that the sample mean shower length for high academy scholars is lesser than 10 twinkles. Option( b) directly reflects this conclusion

B. real Gross Domestic Product (GDP) will rise by $100 billion.

When autonomous investment increases by $100 million, it leads to an increase in the aggregate demand for goods and services.

The increase in aggregate demand causes a chain reaction of increases in national income and output, which is known as the multiplier effect.

The size of the multiplier effect depends on the marginal propensity to consume (MPC), which is the fraction of any additional income that is spent on consumption.

In this case, the MPC is given as 0.75. So, for every $1 increase in autonomous investment, there will be an increase in total spending by $1.75 (i.e., $1 increase in consumption and $0.75 increase in savings).

Therefore, the total increase in spending due to the increase in autonomous investment of $100 million will be $175 million ($100 million x 1.75).

This increase in spending will lead to an increase in real GDP, which is the total value of goods and services produced in an economy, by $100 billion (i.e., $175 million x 1000/1 million).

The power of the test for this two-sided alternate with p1=0.85 and p2=0.75, and given sample size is dependent on the significance level and effect size.

power of a statistical test is the probability of correctly rejecting the null hypothesis when it is false, and is typically denoted by 1-β, where β is the probability of a Type II error (failing to reject a false null hypothesis).

In this case, we need to determine the power of the test based on the given information. Since the alternative hypothesis is two-sided, we need to consider both tails of the distribution. We can use a standard normal distribution and the Z-test statistic formula to calculate the power.

Using the formula: Z = (p1-p2)/sqrt(p(1-p)/n), where p = (p1+p2)/2, we can calculate the Z-value for the given parameters.

p = (0.85+0.75)/2 = 0.8
Z = (0.85-0.75)/sqrt(0.8*(1-0.8)/n)

Assuming a significance level of 0.05 (α = 0.025 for each tail) and a two-sided test, we can calculate the critical Z-values using a standard normal distribution table.

Z(α/2) = 1.96

To calculate the power, we need to find the probability of rejecting the null hypothesis when the alternative hypothesis is true, which means finding the area under the standard normal curve beyond the critical Z-values.

For a two-sided test, the power is equal to 1 minus the probability of failing to reject the null hypothesis (Type II error). Thus,

Power = 1 - β = 1 - P(Z < -Z(α/2)) + P(Z > Z(α/2))

Substituting the values, we get:

Power = 1 - P(Z < -1.96) + P(Z > 1.96)
Power = 1 - 0.025 + 0.025
Power = 0.95

Therefore, the conclusion is that the power of the test for this two-sided alternate with p1=0.85 and p2=0.75, and given sample size is 0.95, rounded to three decimal places. This indicates a high probability of correctly rejecting the null hypothesis when it is false, which suggests that the test is statistically powerful.

The value of y is ± (3√6/2) when x =2

To find the value of y when x = 2, we can use the given differential equation and initial condition.

Given: dy/dx = (x³ + 1)/y

Let's solve the differential equation using the separation of variables:

Separating the variables, we have:

y dy = (x³ + 1) dx

Integrating both sides, we get:

∫ y dy = ∫ (x³ + 1) dx

Integrating the left side:

(1/2) y² = (1/4) x⁴ + x + C

Now, using the initial condition y = 2 when x = 1, we can solve for C:

(1/2) (2²) = (1/4) (1)⁴ + 1 + C

2 = 1/4 + 1 + C

2 = 5/4 + C

C = 2 - 5/4

C = 3/4

Substituting the value of C back into the equation:

(1/2) y² = (1/4) x⁴ + x + 3/4

Multiplying both sides by 2 to eliminate the fraction:

y² = (1/2) x⁴ + 2x + 3/2

Now, we can substitute x = 2 into the equation to find y:

y² = (1/2) (2)⁴ + 2(2) + 3/2

y² = 8 + 4 + 3/2

y² = 27/2

y = ± (3√6/2)

The equation of parabola is x² = 12y and the endpoints of the latus rectum are (-6, 3) and (6, 3).

Hence the correct option is (C).

We know that for parabola, any point on parabola is equidistance from the directrix and the focus.

Given that the focus of the required parabola is = (0, 3)

The directrix is y = -3.

Let the locus of the point on parabola be (h, k).

The distance between (h, k) and (0, 3) = √((h - 0)² + (k - 3)²) = √(h² + (k - 3)²)

The distance of the point (h, k) from y = -3 is = k + 3.

According to properties,

k + 3 = √(h² + (k - 3)²)

(k + 3)² = h² + (k - 3)²

k² + 6k + 9 = h² + k² - 6k + 9

h² = 12k

Since (h, k) is an arbitrary point.

So the equation of the parabola is, x² = 12y

We know that the endpoints of the latus rectum of parabola x² = 4ay are given by (2a, a) and (-2a, a).

Arrange the numbers in ascending order:

48, 111, 121, 125, 126, 141, 149, 198, 223, 224, 238, 263, 292, 327, 330

Find the minimum and maximum values:

Minimum value: 48

Maximum value: 330

Find the median:

To find the median, we need to locate the middle value. In this case, since we have an odd number of data points, the median will be the middle value, which is the 8th number: 149.

Find the lower quartile (Q1):

To find Q1, we need to locate the median of the lower half of the data. Since we have an odd number of data points below the median, the lower quartile will be the middle value of the lower half, which is the 4th number: 121.

Find the upper quartile (Q3):

To find Q3, we need to locate the median of the upper half of the data. Since we have an odd number of data points above the median, the upper quartile will be the middle value of the upper half, which is the 12th number: 263.

Calculate the interquartile range (IQR):

IQR = Q3 - Q1

IQR = 263 - 121

IQR = 142

Determine the outliers:

To identify any outliers, we need to find any values that are below Q1 - 1.5 × IQR or above Q3 + 1.5 × IQR. However, in this case, there are no values that fall outside this range.

Create the box and whisker plot:

Using the minimum value, Q1, median, Q3, and maximum value, we can now create the box and whisker plot.

To prove that gcd (n,n+2) is either 1 or 2 for any integer n, we can use a proof by contradiction. We can conclude that gcd (n,n+2) is either 1 or 2 for any integer n.

Suppose there exists an integer n such that gcd (n,n+2) is not 1 or 2, and let k be the gcd of n and n+2, where k ≥ 3. Then k is a common divisor of n and n+2, and k is not equal to 1 or 2.

Since k divides both n and n+2, we can write n = ka and n+2 = kb, where a and b are integers. Subtracting these equations gives 2 = kb - ka = k (b-a).

Since k is not equal to 1 or 2, it follows that k must be greater than or equal to 3. Therefore, k cannot divide 2, which implies that k (b-a) ≠ 2. This contradicts our assumption that gcd (n,n+2) is not 1 or 2.

Hence, we can conclude that gcd (n,n+2) is either 1 or 2 for any integer n.

Therefore, there are 5,040 ways to assign 7 volunteers to 7 booths for a charity bazaar. The answer is option C: 5,040 ways.

To determine how many ways seven volunteers can be assigned to seven booths for a charity bazaar, we need to use the formula for permutations. A permutation is an arrangement of objects in a specific order, and it is calculated using the following formula:

nPr = n! / (n - r)!

Where n is the total number of objects and r is the number of objects being arranged. In this case, we have 7 volunteers and 7 booths, so n = 7 and r = 7. Plugging these values into the formula, we get:
7P7 = 7! / (7 - 7)!
7P7 = 7! / 0!
7P7 = 7!
So there are 7! (7 factorial) ways to assign 7 volunteers to 7 booths. To find the actual value, we can calculate:

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1
7! = 5,040

Using the definition of the derivative of a function at a point, we can show that the derivative of a constant function is equal to 0.

To understand why this is the case, recall that the derivative of a function f at a point c is defined as the limit of the difference quotient as h approaches 0:

f'(c) = lim (h -> 0) [f(c + h) - f(c)] / h

Now, let's consider a constant function f(x) = k, where k is some constant. Then, for any value of x, we have f(x) = k.

Using the definition of the derivative, we can find the derivative of f at any point c:

f'(c) = lim (h -> 0) [f(c + h) - f(c)] / h

= lim (h -> 0) [k - k] / h

= lim (h -> 0) 0 / h

= 0

Since f'(c) = 0 for all values of c, we can conclude that the derivative of a constant function is equal to 0.In conclusion, using the definition of the derivative of a function at a point, we can show that the derivative of a constant function is equal to 0.
