Data points that differ from the distribution's norm are considered outliers. a figure that falls "outside" of the normal range for the record (either significantly lower or substantially greater). For instance, when the scores are 25, 29, 3, 32, 85, 33, 27, 28, etc., both 3 and 85 are "outliers". Step aside. To spot outliers, look for numbers that are noticeably greater or lower than all other values. Value 4 is an outlier since it is much smaller than all other values. An outlier is a finding in a population sample selected at random that deviates unusually from other values.

There seem to be two possible outliers in the data, according to the scatter diagram you gave.

He should use 11.11 pounds of the $0.90 per pound coffee, and 16.89 pounds of the $2.40 per pound coffee for a total cost of 28 pounds.

x + y = 28

0.90x + 2.40y = 38.20

x = 11.11, y = 16.89

The grocer wants to mix 28 pounds of two kinds of coffee, one selling for $0.90 per pound and the other for $2.40 per pound, and sell it for $1.45 per pound. To determine how many pounds of each kind to use in the new mix, we can set up a system of equations. Let x represent the quantity of pounds of coffee priced at $0.90 per pound and y the quantity of pounds of coffee priced at $2.40 per pound. Thus, x + y = 28 (the total number of pounds) and 0.90x + 2.40y = 38.20 (the total cost of the 28 pounds, at $1.45 per pound). Solving this system of equations yields x = 11.11 pounds of the $0.90 per pound coffee and y = 16.89 pounds of the $2.40 per pound coffee.

By 12.57 feet the circumference of outer circle greater than the circumference of the inner​ circle

The circle's boundary is the length of the circle's circumference, sometimes referred to as its perimeter. whereas the size of a circle determines the space it occupies.

The formula for calculating a circle's circumference is written as

Circumference = πD

where D stands for the circle's diameter.

The inner circle is 44 feet in diameter. It means that

The mass of the cube for the object that has the side lengths of 56 cm is 0.043904 g.

1. To find the number of people in an area of 1400 m by 1.3 km, we need to first convert the measurements to the same unit. Since the population density is given in people/km2, we will convert the measurements to kilometers.
1400 m = 1.4 km
Now we can multiply the two measurements to find the area:
1.4 km x 1.3 km = 1.82 km2
Next, we can use the population density to find the number of people in this area:
14 people/km2 x 1.82 km2 = 25.48 people
Therefore, we would expect to find approximately 25 people in an area of 1400 m by 1.3 km.

2. To find the mass of the cube, we first need to find the volume. Since the side lengths are given in centimeters, we will convert them to meters:

235mm for a and 178mm for b.

c = 273 mm

For any triangle with side a and angle A across from side a, the following is true in accordance with the Law of Cosines:

A² = 2bc cos - b² + c²

Angle A is the angle at Niagara Falls, and we're trying to find it. The formula above is rearranged to give us:

cos A = (b²+c²-a²)/2bc

The area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

The area of a trapezoidal region is given by the formula A = 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height. This formula can be derived by dividing the trapezoid into two right triangles and a rectangle, and finding the area of each of these shapes.

First, let's consider the two right triangles. The height of each of these triangles is h, and the lengths of their bases are (a-b)/2 and (b-a)/2, respectively. The area of each of these triangles is therefore 1/2h(a-b)/2 = 1/4h(a-b).

Next, let's consider the rectangle. The length of this rectangle is b, and the height is h. The area of this rectangle is therefore bh.

The area of the trapezoidal region is the sum of the areas of the two right triangles and the rectangle. This gives us:

A = 1/4h(a-b) + 1/4h(b-a) + bh

Simplifying this equation gives us:

A = 1/2h(a+b)

Therefore, the area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

The given statement in the problem (f/g)(-2) = -6/5 is true.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

f(x) = 3x²

g(x) x - 8 ; (f/g)(-2) = -6/5

Now,

To evaluate (f/g)(-2), we need to divide f(-2) by g(-2).

We have f(x) = 3x², so f(-2) = 3(-2)² = 12.

We also have g(x) = x - 8, so g(-2) = (-2) - 8 = -10.

Using angle theorems the value of x = 67.5°

Angle theorems are rules that govern the properties of angles.

Given that we have the figure and we desire to find angle x, we proceed as folllows.

Now, we notice that one angle is a right angle and it is equal to 90°.

Also, we notice that all the angles meet at the same point.

So, we have that

x + 3x + 90° = 360° (sum of angles at a point)

Solving for x, we have that

x + 3x + 90° = 360°

4x + 90° = 360°

4x = 360° - 90°

4x = 270°

The population after 4 years will be 12,155.06. It will take approximately 22.52 years for the population to triple.

The population of a town grows proportionally to its current population. This means that the larger the population, the more it will grow. To determine the population after 4 years, we can use the formula:

P = P0 * (1 + r)^t

Where P is the final population, P0 is the initial population, r is the growth rate, and t is the time in years. Plugging in the values given in the question, we get:

P = 10,000 * (1 + 0.05)^4

P = 10,000 * 1.21550625

P = 12,155.06

Therefore, the population after 4 years will be 12,155.06.

To determine how long it will take the population to triple, we can use the same formula, but set P to 3 * P0 and solve for t:

3 * 10,000 = 10,000 * (1 + 0.05)^t

3 = (1 + 0.05)^t

ln(3) = t * ln(1.05)

t = ln(3) / ln(1.05)

t = 22.52

Therefore, it will take approximately 22.52 years for the population to triple.
