Yes, they are statistically different.

Statistical significance is a term used to indicate that a result from a statistical test is likely to be reliable and reproducible. It is the probability that a result is caused by something other than random chance. Statistical significance is usually determined by calculating the probability, or p-value, that the result occurred by chance. A result is deemed to be statistically significant if the p-value is below a certain threshold. This threshold is typically set at 0.05, but can be adjusted depending on the study.

A p-value below 0.05 is generally considered to be statistically significant, indicating that the differences observed between the two groups are unlikely to have occurred by chance. In this case, a p-value of 0.03 is well below the threshold, indicating that the two groups are statistically different

Mr. Finn's rent in the next 3 years will be £ 833.49

To find the rent, calculate how much it will increase in the first and in the second year by using calculating percentages individually or using the compound interest formula. From the find total rent for next years. Using the total rent in the second year find the rent in 3rd year.

Here we have

The rent paid by Mr. Finn is £700 per month in rent.

His landlord informed him that rent will increase by 5% for the next two years and by 8% after that.

The rent in the 1st year = 700 + 5% of 700

= 700 + (5/100) 700

= 700 + 35 = 735  

In the second year again the rent will increase by 5%

The total rent in the second year = 735 + 5% of 735

= 735 + 36.75 = 771.75

After 2 years, the increment will be 8%

So, The total rent in the 3rd year year = 771.75 + 8% of 771.75

= 771.75 + (8/100) 771.75

= 833.49

Therefore,

Mr. Finn's rent in the next 3 years will be £ 833.49

For given coordinates of a linear equation, the slope will be 3/4 i.e. B.

What is a linear equation, exactly?

When the greatest power of a variable is 1, the equation is said to be linear. Other term used for it is a one-degree equation. The standard form of a linear equation with one variable is Ax + B = 0. There are three variables in this equation: x, A, and B. A denotes a coefficient. A linear equation with only two variables is commonly written as Ax + By = C. There is three more constants added to the constant C: the variables x and y, the coefficients A and B, and the variables.

and general equation of line is y=mx+c

where m=slope=y2-y1/x2-x1

Now,

Here given coordinates are , (-3,4) and (1/7)

then (x1,y1) and (x2,y2) are  (-3,4) and (1/7) respectively

so slope=m=7-4/1-(-3)=3/4

We have discussed what is skewed distribution and how to deal with skewed data as mentioned below.

What is a skewed distribution?

When one tail is longer than the other, the distribution is said to be skewed. The asymmetry of a distribution is defined by skewness. These distributions are asymmetric, in contrast to the well-known normal distribution and its bell-shaped curve. Because the data are not equally distributed on both sides of the distribution peak, the two parts of the distribution are not mirror images.

A) The direction of outliers is revealed by skewness. A distribution curve's tail is longer on the right side when there is a positive skew. As a result, the distribution curve's outliers are more extreme to the right and closer to the mean to the left. Skewness simply conveys the direction of outliers; it does not convey the number of outliers.

B) Lower or upper boundaries on the data frequently cause skewed data. In other words, data with a lower bound are frequently skewed right, whereas data with an upper bound are typically skewed left.

C) One popular method for handling skewed outcome data is to logarithmically transform each observation before conducting the analysis with the resulting values.

D) It is likely that the income distribution curve you plot on a graph will be positively skewed to the right. If the majority of people earn normal earnings and a smaller proportion earn high incomes, then this would happen.

Therefore this is what skewed distribution is and the above mentioned ways are how one deals with skewed data in research.

Answer:6

Step-by-step explanation: because the 2 feet already has four pieces and if you add two more pieces to it there will be six in total.

The answer is 4 times the cube of the first number minus the sum of the second number and two times the third number. That is the result of the calculation is -6.

To calculate this, first, we multiply the first number by itself twice to get the cube of the first number. Then, we subtract the sum of the second and third numbers multiplied by two from the cube of the first number. This result is our answer.

For example, let's say we have the numbers 2, 3, and 4. We first calculate the cube of 2, which is 8. Then, we subtract the sum of 3 and 4 multiplied by two, which is 14. So, the final answer is 8 - 14 = -6.

We can also show the stepwise calculation as follows:

= 2³ - (3 + 2 × 4)

= 8 - 14

= -6

If two parallel lines are crossed by a transversal, the value of x is option (b) x = 70 degrees

When two parallel lines are intersected by a transversal, eight angles are formed. Two of these angles are vertical angles, which are opposite angles that share the same vertex and are formed by the intersection of two lines.

Vertical angles are always congruent, meaning they have the same measure. This is a geometric property that is true regardless of the angle's degree measurement.

In this problem, one of the vertical angles is given to be 70 degrees. Therefore, the other vertical angle must also have a measure of 70 degrees. This means that the value of x, which is the measure of one of the vertical angles, is also 70 degrees.

So, correct option is (b) x = 70 degrees.

Answer:

Please Mark Brainlaiest Answer

Step-by-step explanation:

The best linear approximation for f(x) = cos(x) near x = pi/2 is given by the equation:

y = -(x - pi/2) + 1

This is because the linear approximation should have the same value and slope as the original function at x = pi/2.

At x = pi/2, the value of f(x) = cos(pi/2) = 0. The value of the linear approximation at x = pi/2 is:

y = -(pi/2 - pi/2) + 1 = 1

So, the value of the linear approximation matches the value of the original function at x = pi/2.

The slope of the original function at x = pi/2 is -sin(pi/2) = -1. The slope of the linear approximation is:

y' = -1

So, the slope of the linear approximation also matches the slope of the original function at x = pi/2.

Therefore, the best linear approximation for f(x) = cos(x) near x = pi/2 is:

y = -(x - pi/2) + 1

Hence, the correct option is "y equals negative x plus pi over 2 plus 1".

1. The probability the project will be finished in 62 weeks or less is 0.6915. 2.The probability the project will be finished in longer than 65 days is 0.8944.

The standard score in statistics is the amount of standard deviations that a raw score (i.e., an observed value or data point) deviates from or exceeds the mean of the thing being observed or measured. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.

It is determined by deducting the population mean from a given raw score, then dividing the result by the population standard deviation. Standardizing or normalising is the process of transforming a raw score into a standard score.

Given that,

mean = 60 weeks

SD = 4 weeks

1. P (p ≤ 62) = P(z ≤ 62)

The z-score is given by:

z-score = x - mean / SD

Substituting the values we have:

z-score = 62 - 60/4 = 2/4 = 0.5

P(z ≤ 0.5) = 0.6915 (Using the z -table)

Hence, the probability the project will be finished in 62 weeks or less is 0.6915.

Similarly,

2. P(z > 65) = P(z > 1.25) = 0.8944

Hence, the probability the project will be finished in longer than 65 days is 0.8944.

The direct distance between the White House and the Pentagon is approximately 3.067 miles.

Distance is a measure of how far apart two objects or points are from each other. It is a fundamental concept in mathematics, physics, and other scientific disciplines, and plays a crucial role in our everyday lives.

Distance can be measured in various units, such as meters, kilometers, miles, feet, and inches, depending on the context and application. In mathematics, the distance between two points in a plane can be found using the Pythagorean theorem, which states that the distance between two points (x1, y1) and (x2, y2) is given by the formula:

distance = √((x2-x1)² + (y2-y1)²)

In this formula, the square of the difference in the x-coordinates and the y-coordinates of the two points are added and then the square root of the sum is taken to obtain the distance.

Using the distance formula, the direct distance between the two buildings is:

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

where (x1, y1) = (-8,-6) and (x2, y2) = (-1,10)

d = sqrt[(-1 - (-8))^2 + (10 - (-6))^2]

d = sqrt[7^2 + 16^2]

d = sqrt(49 + 256)

d = sqrt(305)

Since each unit on the grid represents 0.125 miles, we can convert the answer to miles by multiplying by 0.125:

d = sqrt(305) * 0.125

d = 3.067 miles (rounded to 3 decimal places)

Therefore, the direct distance between the White House and the Pentagon is approximately 3.067 miles.

The domain where fx) is 1-to-1 is x ≥1 , and the inverse there is:

f⁻¹(x) =  √x + 1

Here we have the quadratic function:

f(x) = (x - 1)^2

If we look from the vertex to the right (or the left, is the same) we will have an one to one function.

Here the vertex is at x = 1

f(1) = (1 - 1)^2 = 0

Then for x ≥1 we have an one to one function.

Noe let's find the inverse, if the inverse is f⁻¹(x), then we must have that:

f( f⁻¹(x) ) = x

Solving that:

(f⁻¹(x)  - 1)^2 = x

the equation of the line perpendicular to 5x - 4y = 10 and passing through the point (5,12) is y = -(4/5)x + 16.

How to determine?

To find the equation of the line perpendicular to the line 5x - 4y = 10 and passing through the point (5,12), we need to first find the slope of the given line.

Rewriting the equation of the given line in slope-intercept form (y = mx + b), we get:

5x - 4y = 10

-4y = -5x + 10

y = (5/4)x - 5/2

The slope of this line is (5/4), so the slope of any line perpendicular to it is the negative reciprocal of (5/4), which is -(4/5).

Now we can use the point-slope form of a linear equation to find the equation of the perpendicular line. The point-slope form is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope.

Plugging in the values we have, we get:

y - 12 = -(4/5)(x - 5)

Expanding and simplifying, we get:

y - 12 = -(4/5)x + 4

y = -(4/5)x + 16

Therefore, the equation of the line perpendicular to 5x - 4y = 10 and passing through the point (5,12) is y = -(4/5)x + 16.
