Step-by-step explanation:

a. residual is much larger than the rest of the residual values.

In regression analysis, an outlier refers to an observation that significantly deviates from the expected pattern or trend of the data. Specifically, it is an observation whose residual (the difference between the observed value and the predicted value) is much larger than the residuals of the other observations.

Outliers can have a considerable impact on the regression model, affecting the estimated coefficients and overall model fit. It is important to identify and assess outliers to determine if they are influential or if they should be treated or removed to ensure the reliability and validity of the regression analysis.

Answer: C

Step-by-step explanation:

4x × mn = 4xmn

4xmn × 15 = 60xmn

60xmn × 2 = 120 xmn

Put variables in alphabetical order: 120mnx!

Write both sides as powers of 2:

\(4^x=(2^2)^x=2^{2x}\)

\(\left(\dfrac18\right)^{x+5}=8^{-x-5}=(2^3)^{-x-5}=2^{-3x-15}\)

Since both powers of 2 are equal, the exponents are equal:

2x = -3x - 15

5x = -15

x = -3

The radius of the spherical part is 3 inches and the length of the tube is 21 cm.

The capacity of a cylinder, which determines how much material it can hold, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, can be immersed in it uniformly.

Given that the volume when the water is fully dipped is 4554 / 7 cm³. The volume when the length is 9 cm empty is 396 cm³.

The two equations can be formed as below:-

4554 / 7 = πr²l + (2/3)πr³

396 = πr²( l - 9 ) + (2/3)πr³

Subtract the second equation from the first,

( 4554 / 7 ) - 396 = 9πr²

9πr² = 254.5

r² = 9

r = 3 cm

The length will be calculated as:-

4554 / 7 = πr²l + (2/3)πr³

4554 / 7 = π( 3 )²l + (2/3)π(3)³

l = 21 cm

Therefore, the tube's length is 21 cm, and the spherical part's radius is 3 inches.

Given that a company's vice president's salary n years after becoming vice president is defined by the formula S(n) = 70000(1.2)". We have to determine which of the following statements is true:

She will be receiving a 2% raise per year. Her salary will increase $14,000 every year. The percent increase of her salary is 120% every year. Her salary is always 0.2 times the previous year's salary. The percent increase of her salary is 20% every year.

To calculate the salary of the vice president after n years of becoming a vice president, we use the given formula:

S(n) = 70000(1.2)

S(n) = 84000

The salary of the vice president after one year of becoming a vice president: S(1) = 70000(1.2)

S(1) = 84000

The percent increase of her salary is: S(n) = 70000(1.2)n

S(n) - S(n-1) / S(n-1) × 100%

S(n) - S(n-1) / S(n-1) × 100% = (70000(1.2)n) - (70000(1.2)n-1) / (70000(1.2)n-1) × 100%

S(n) - S(n-1) / S(n-1) × 100% = 20%

Answer:

The percentage of Americans which have both type A and B in their blood is 7%

Step-by-step explanation:

People with Type A: 43% = 0.43

People with Type B: 15% = 0.15

People with neither: 46% =  0.46

Since 46% have neither,so,

1-0.46 = 0.54 = 54%

54% will have type A or type B or both

Now, out of these, if we remove the 15% with type B,

we are left with,

0.54-0.15 = 0.39

These people don't have type B but have type A

Finally, since 0.46 have type A, the remaining 0.46-0.39 = 0.07 will have both type A and type B

So the percent of Americans which have type A and B in their blood is 7%

Answer: hi!  i really hope my explaination helps you understand this! pls vote for brainliest

the percentage should finally = 7 percent

reasoning ;

population with type a is 43 percent.  

population with type b is 15 percent .

46 percent have neither.

we would then do this calculation:

1 minus 46 percent = 0.46 which  should equal 54 percent so then when we remove type b we should be left with this 54 percent -15 percent equals 39 percent or 0.39. so then,  0.07 ( the amount of people who have both type a and b ) should be the answer.

The division of 36 acorns among the squirrels would be as follows:
- The black squirrel carries 35 acorns in 7 trips.
- The gray squirrel carries 1 acorn in 1 trip

1. Determine the number of times each squirrel can carry acorns:
  - The brown squirrel can carry 2 acorns at a time, so it will need to make 36 / 2 = 18 trips.
  - The gray squirrel can carry 3 acorns at a time, so it will need to make 36 / 3 = 12 trips.
  - The black squirrel can carry 5 acorns at a time, so it will need to make 36 / 5 = 7 trips.

2. Allocate the acorns to each squirrel:
  - Start by giving the black squirrel 7 trips worth of acorns, which is 7 x 5 = 35 acorns.
  - Since there are only 36 acorns in total, the black squirrel can take all of them.
  - This leaves 36 - 35 = 1 acorn remaining.

3. Distribute the remaining acorn(s) to the other squirrels:
  - If there is only 1 acorn left, it can be given to either the brown or gray squirrel.
  - Since the gray squirrel can carry more acorns per trip, it makes sense to give the remaining acorn to the gray squirrel.

So, the division of 36 acorns among the squirrels would be as follows:
- The black squirrel carries 35 acorns in 7 trips.
- The gray squirrel carries 1 acorn in 1 trip.

This is just one possible way to divide the acorns, considering the carrying capacities of the squirrels. The actual division may vary depending on the specific situation and requirements.

Answer: The answer is -5 x 8

Step-by-step explanation:

First of, we add the numbers in the parenthesis, 5+3, which equals 8.

Since we got rid of the parenthesis, a number next to a number means to multiply.

Since we are simplifying and not answering the equation, we leave the equations as -5 x 8

The half life period is the time in which only half of the given population remains. It can be represented through this equation:

For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.

This can be calculated simply by multiplying the given half-life by 3:

EXPLANATION:

Given;

We are given a parallel pair of lines m and n, and a transversal that cuts both lines.

Required;

We are required to find the value of x.

Step-by-step solution;

When a pair of parallel lines are cut by a transversal, the angle formed by the point of intersection of one line and the transversal is equal to that formed by the other line and the transversal when they both lie on the same side of the transversal.

This means on the diagram given;

This means angle 167 on line n is equal to angle 167 on line m. These are called corresponding angles.

The same applies to angle x on the line m and the other angle on line n. They both are also corresponding angles.

Next, take note that angles that lie on either side of a vertex where two lines intersect are called vertically opposite angles (or just opposite angles).

Therefore, angle x = 167 and angle 167 = x.

The formula g(x)=-4+(x-3)²The parent function, f(x) = x², is translated both vertically and horizontally into 2, or 2. In more precise terms, it moves the graph 3 units to the right and 4 units downward while keeping the parabola's opening's shape and direction.

The difference between how an object is described in two distinct coordinate charts that overlap, where the description of the same set may alter in different coordinates, is referred to as a transition function. Even in Euclidean space, this can be seen because any rotation of the standard,, and axes results in a different set of coordinates.

A quadratic function is one that has the formula f(x)=ax²+bx+c, where a, b, and c are real integers, and an is a positive integer. The conventional form of a quadratic function is this form. The quadratic function's graph is a U-shaped curve known as a parabola.

according to questions,

To see this, we can compare the graph of g(x) to the graph of f(x):

The vertex of f(x) is at (0,0), while the vertex of g(x) is at (3,-4). This means that the graph of g(x) has been shifted 3 units to the right and 4 units down from the graph of f(x).

The shape of the graph is still a parabola, but it is narrower than the graph of f(x) because of the squared term. However, the direction of the opening of the parabola is the same as in f(x), which is upwards.

The axis of symmetry is still the vertical line x = 0, since this is the line that bisects the parabola. However, the y-intercept has changed to y = -4, since the graph has been shifted down by 4 units.
