An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms.

The distance on the map that represents an actual distance of 4 kilometers is 3.2cm.

The actual number of kilometers that is represented by 5 centimeters on the map is 6.25 kilometers.

A scale drawing is a smaller version of a larger image. In this question, the map is a scale drawing of the city. The scale drawing is reduced using constant dimensions using a scale.

A scale gives the ratio of the length of the scale drawing to the actual diagram or object. In this question, every 4cm on the map represents 5km in the city.

The distance on the map = (4 x 4) / 5

16 / 5 = 3 1/5 cm = 3.2 cm

The actual distance = (5 x 5) / 4

= 25 / 4 = 6 1/4 = 6.25 kilometers

The Volume of the given Hemisphere is  1071.8 cm³ rounded to 1 decimal place whose radius is 8cm

The Volume of the sphere  is given by the formula 4/3 πr³

The volume of hemisphere is half of sphere

So, The volume of hemisphere is 2/3 πr³

From the given figure it is clear that the radius of the hemisphere is 8cm

Here, we will use the value of π as 3.14 and not 22/7

So, Substituting the values in the formula of Volume of hemisphere

the Volume of hemisphere =2/3 π (8)³

                                      =2/ 3× 3.14 × 512

The value of given expression for x=0 is 1, x=-2 is 0.44 and x=2 is 2.25.

Given the expression is (3/2)ˣ.

Firstly, we will simplify the given expression (3/2)ˣ for x=0.

Substitute the value x=0 in given expression, we get

(3/2)ˣ =(3/2)⁰

As we know that something raise to power zero is 1.

So, we get

(3/2)ˣ =1

Now, we will simplify the given expression (3/2)ˣ for x=-2.

Substitute the value x=2 in given expression, we get

(3/2)ˣ =(3/2)²

Now, we will square the expression to simplify it, we get

(3/2)ˣ =9/4

(3/2)ˣ =2.25

Furthermore, we will simplify the given expression for x=-2.

Substitute the value x=-2 in given expression, we get

(3/2)ˣ =(3/2)⁻²

Now, we will square the given expression, we get

(3/2)ˣ =(9/4)⁻¹

Further, we will divide it above expression by 1 to remove negative sign, w eget

(3/2)ˣ =1/(9/4)

(3/2)ˣ =4/9

(3/2)ˣ =0.44

Hence, the value of expression (3/2)ˣ  for x=0, 2 and -2 is 1, 2.25 and 0.44.

The probability that a randomly selection of 20 toasters for testing, no more than one is defective is: 0.9401

To solve this exercise the formula and the procedure that we have to use for binomial distribution is:

Where:

Information about the problem:

Applying the binomial distribution formula, we get:

P(x) = n! /[x! *(n-x)!] * pˣ * (1 - p)ⁿ⁻ˣ

P(x) = 20! /[x! *(20-x)!] * 0.02ˣ * (1 - 0.02)²⁰⁻ˣ

Using the P formula to calculate the probability that no more than one of these toasters is defective, we have:

P = P(0) + P(1)

P(0) = 20! /[0! *(20-0)!] * 0.02⁰ * (1 - 0.02)²⁰⁻⁰

P(0) = 20! /(0!*20!) * 0.02⁰ * (0.98)²⁰

P(0) = 1/0! * 1 * 0.6676

P(0) = 1/1 * 1 * 0.6676

P(0) = 0.6676

P(1) = 20! /[1! *(20-1)!] * 0.02¹ * (1 - 0.02)²⁰⁻¹

P(1) = 20! /(1!*19!) * 0.02¹ * (0.98)¹⁹

P(1) = (20*19!) / (1!*19!) * 0.02¹ * (0.98)¹⁹

P(1) = 20/1! * 0.02 * 0.6812

P(1) = 20 * 0.02 * 0.6812

P(1) = 0.2725

P = P(0) + P(1)

P =  0.6676 + 0.2725

P =  0.9401

The upper and lower bounds can be found by dividing the degrees of accuracy by 2 and then subtracting and adding with the value to give the lower and upper bounds respectively.

For a- 64 mins (nearest 1 min)

As the degree of accuracy is to the nearest 1 min;

1 min ÷ 2 = 0.5 min

Upper bound = 64 + 0.5 = 64.5 min

Lower bound = 64 - 0.5 = 63.5 min

For c- 30m/s (nearest 5m/s)

5m/s ÷ 2 = 2.5 m/s

Upper bound = 30 + 2.5 = 32.5 m/s

Lower bound = 30 - 2.5 = 27.5 m/s

For b- 20g (nearest 10g)

10g ÷ 2 = 5

Upper bound = 20 + 5 = 25g

Lower bound = 20 - 5 = 20g

For d- 7500(nearest 100mm)

100mm ÷ 2 = 50mm

The Magnitude of all the vectors is the same.

As you know, a vector is an object with both Magnitude and direction. To find the size of a vector, we need to calculate the length of the vector. Variables such as velocity, distance, force, and momentum are vector variables. But velocity, mass, distance, volume, temperature, etc., is a scalar quantities. A vector has both Magnitude and direction, while a scalar has only one Magnitude.

The Magnitude of a vector is the length of the vector. The Magnitude value of vector a is represented by ∥a∥.

Since lines a and b have the same slope, then: the lines are parallel.

The slope of a line is the rise/run or change in y / change in x. When two lines lie parallel to each other, they will have equal slope value.

On the other hand, when two lines lie perpendicularly to each other, their slopes will be negative reciprocal.

For example, if a line has a slope of 2/3, the slope of the line that is parallel to it will be 2/3 also, while the slope of the line that is perpendicular to it will be -3/2.

Thus:

The slope of line a = 2/3

The slope of line b = 2/3

Therefore, since lines a and b have the same slope, then: the lines are parallel.

The function that represents the value after x years of a new delivery van that costs $ 25,000 and depreciates 15 % each year is option (C) y = 25000(0.85)ˣ.

Consider the compound interest formula:

y = P(1 + r/n)ⁿˣ

y here stands for the car's potential value.

P represents the value of the new car.

r is a measure of how quickly a car's value declines.

The number n indicates how frequently the car's value depreciates each year.

x represents the number of years.

Given P = 25000

r = -15% = -0.15 (Since the value of the car depreciates)

n = 1

x = x

Using the given values, we get the function as,

y = 25000(1 + (-0.15)/1)ˣ

⇒ y = 25000(1 - 0.15)ˣ

⇒ y = 25000(0.85)ˣ

Therefore, the function that represents the value after x years of a new delivery van that costs $ 25,000 and depreciates 15 % each year is option (C) y = 25000(0.85)ˣ.
