The first number is 17 and the second number is -1. Therefore:
The smaller of the two numbers is -1.
The larger of the two numbers is 17.

Let x be the first number and y be the second number.
From the first statement, we know that:
x + 2y = 15
From the second statement, we know that:
2x + y = 33
To solve for x and y, we can use elimination or substitution. Here, we'll use substitution.
Solve the first equation for x:
x = 15 - 2y
Substitute this expression for x into the second equation:
2(15 - 2y) + y = 33
Distribute the 2:
30 - 4y + y = 33
Combine like terms:

30 - 3y = 33
Subtract 30 from both sides:
-3y = 3
Divide both sides by -3:
y = -1
So the second number is -1. Now we can find the first number using either of the original equations.

Let's use the first one:
x + 2(-1) = 15
Simplify:
x - 2 = 15
Add 2 to both sides:
x = 17
So the first number is 17 and the second number is -1. Therefore:
The smaller of the two numbers is -1.
The larger of the two numbers is 17.

This means that the probability that a doll selected at random will blink and have moving limbs is 0.26.

There is a 50% chance that the outcome will be heads, thus 50 heads are to be expected. When we really attempt it, though, we might instead get 48 heads, 55 heads, or anything else at all, but in most situations, it will be a figure close to 50.

calculation

If B is a set of moveable arms and legs and A is the number of dolls that can blink, then P(A)=0.47, P(B)=0.56, P(A' and B')=0.23,

therefore P(A or B)=1-0.23=0.77, and

P(both blink and moveable limbs)=P(A and B)=0.47+0.56-0.77=0.26.

This means that the probability that a doll selected at random will blink and have moving limbs is 0.26.

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

The median would be 22:

Step-by-step explanation: The median is the number that is in the middle

Simply defined, the median is the number right in the middle of a set.

But before I get down to finding the median, I will order the numbers from least to greatest:

15, 17, 19, 20, 21, 22, 23

Now, the middle number is 20. So that's the median.

As for the range, it's the difference between the largest number and the smallest one:

Range = Greatest number - Smallest number

           = 23 - 15

           = 6

In summary, the median, the number in the middle, is 20, and the range, the difference between the largest number and the smallest one, is 6.

Answer:To determine the possible scales of the map, we need to calculate the ratio of the distance on the map to the corresponding distance on the ground in the actual state. We can do this using the following formula:scale = distance on map ÷ distance on groundFirst, we need to convert the dimensions of Kansas from miles to inches using a common scale factor. Since 1 mile is equal to 63,360 inches, we have:Length of Kansas: 410 miles × 63,360 inches/mile = 25,984,600 inchesWidth of Kansas: 210 miles × 63,360 inches/mile = 13,315,200 inchesNow we can calculate the possible scales of the map based on the dimensions of the page in Jada's book, which is 5 inches by 8 inches:For the length of Kansas:scale = 5 inches ÷ (25,984,600 inches ÷ 2.54 cm/in) = 0.0000484scale = 8 inches ÷ (25,984,600 inches ÷ 2.54 cm/in) = 0.0000774For the width of Kansas:scale = 5 inches ÷ (13,315,200 inches ÷ 2.54 cm/in) = 0.0000962scale = 8 inches ÷ (13,315,200 inches ÷ 2.54 cm/in) = 0.0001539Therefore, the possible scales of the map are 1:20,655, and 1:10,326.

Answer:

i. 33.51 cm³

ii. 14.14 cm³

iii. 231.61 g

Step-by-step explanation:

(i) the total volume of the paper weight,

Since the paper weight is in the form of a cone, its volume is the volume of a cone V = πD²h/12 where D = diameter of cone = 4 cm and h = height of cone = 8 cm

So, V = πD²h/12

V = π(4 cm)² × 8 cm/12

V = 16π cm² × 8 cm/12

V = 128π cm³/12

V = 402.124 cm³/12

V = 33.51 cm³

(ii) the volume of the wooden portion,

The volume of the wooden portion, V' = πr'²h'/3 where r' = radius of wooden portion and h' = height of wooden portion

From similar triangles in the figure, we have

height of wooden portion, h'/radius of wooden portion, r' = height of paper weight, h/radius of paper weight, r

h'/r' = h/r where r = D/2 where D =diameter of paper weight = 4 cm. So, r = 4 cm/2 = 2 cm

and h' = height of paper weight - height of lead portion = 8 cm - 2 cm = 6 cm

So,

r' = rh'/h = 2 cm × 6 cm/8 cm = 12 cm²/8 cm = 1.5 cm

So, V' = πr'²h'/3

V' = π(1.5 cm)² × 6 cm/3

V' = π2.25 cm² × 2 cm

V' = 4.5π cm³

V' = 14.14 cm³

(iii) the total mass of the paper weight.

The total mass of paper weight, m = mass of wooden portion + mass of lead portion = ρ'V' + ρ"V" where ρ' = density of wood = 0.9 g/cm³, V' = volume of wooden portion = , ρ" = density of lead = 11.3 g/cm³ and V" = volume of lead portion = V - V' = 33.51 cm³ - 14.14 cm³ = 19.37 cm³

So, m = 0.9 g/cm³ × 14.14 cm³ + 11.3 g/cm³ × 19.37 cm³

m = 12.726 g + 218.881 g

m = 231.607

m ≅ 231.61 g

The length of the line segment AB is 5 units.

Unfortunately, you haven't provided any information about PQ such as its location or any other data to help solve the question.

Therefore, it's impossible to determine the length of PQ using the given options. However, here is an explanation of how to find the length of a line segment using the distance formula, which may help you in solving similar questions in the future.

The distance formula is used to find the distance between two points in a coordinate plane, such as the length of a line segment. The formula is:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where d is the distance, (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.

To use the distance formula, you first need to find the coordinates of the two points that make up the line segment. Then, substitute these coordinates into the formula and simplify to find the distance.

For example, let's say you have two points: A(1, 2) and B(4, 6), and you want to find the length of the line segment AB. Using the distance formula:

d = √((4 - 1)² + (6 - 2)²)
d = √(3² + 4²)
d = √(9 + 16)
d = √25
d = 5

Remember, the distance formula can be applied to any two points in a coordinate plane to find the distance between them.

The estimated error in the calculated area is approximately 3.2ft²

To estimate the error in the calculated area of a square, use linear approximation or differentials.

The area of a square is given by the formula A = s², where s represents the length of a side.

Calculate the area of the square using the given side length of 16 ft:

A = (16 ft)²

A = 256 ft²

Now, let's consider the possible error in the side length, which is ±0.1 ft. Treat this error as a change in the side length (Δs) and use linear approximation or differentials to estimate the corresponding change in the area (ΔA).

Using linear approximation, express the change in the area as:

ΔA ≈ 2s Δs

Substituting the values:

ΔA ≈ 2(16 ft)(0.1 ft)

ΔA ≈ 3.2 ft²

Therefore, the estimated error in the calculated area is approximately 3.2ft².

Here is an example of how you could exchange consecutive pairs of integers in an array using the swap procedure:

def swap(array, i, j):

 temp = array[i]

 array[i] = array[j]

 array[j] = temp

# create an array of randomly ordered integers

import random

array = [random.randint(1, 100) for _ in range(10)]

print(array)

# exchange each consecutive pair of integers in the array

for i in range(0, len(array)-1, 2):

 swap(array, i, i+1)

print(array)

This code creates an array of 10 randomly ordered integers, then uses a for loop to iterate over the array and exchange each consecutive pair of integers using the swap function. The for loop starts at index 0 and increments by 2 each iteration, so it processes the elements at even indices (0, 2, 4, etc.). The swap function takes three arguments: the array, and the indices of the elements to be swapped. It uses a temporary variable to store one of the elements, then swaps the elements by reassigning them to the correct indices. Finally, the modified array is printed to the console.
