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.

In mathematics, equality is a relationship that states that two quantities have the same value or that two mathematical expressions represent the same mathematical object.

Someone or something that is equal to another has the same quantity, value, or rights as that other thing. One cup and eight ounces are equivalent, for instance. Equal pay for equal work performed by men and women is an illustration of equality.

If both operands have the same value, the equal-to operator (==) returns true; otherwise, it returns false. If the operands do not have the same value, the not-equal-to operator (!=) returns true; otherwise, it returns false.

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

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

The lower and upper bounds for the following to the given degrees of accuracy are: a- 64 mins (63.5 ≤ 64 < 64.5) c- 30m/s (27.5 ≤ 30 < 32.5) b- 20g (15 ≤ 20 < 25) d-7500mm (7450 ≤ 7500 < 7550)

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

Upper bound = 7500 + 50 = 7550mm

Lower bound = 7500 - 50 = 7450mm

We need to know about logarithm to solve this problem. The value of the given logarithm is 1.

Logarithm is an exponent that the base is raised to inorder to get a certain number. There are few rules of logarithm, log a +log b can be written as log ab, log a -log b can be written as log a/b, when the number whose logarithm is calculated has been raised to a power then the power can be multiplied to the log itself. When logarithm is written as log with no mentioned base then the base is 10. The log of a number same as the base is always 1 and the log of 1 is always zero because a nonzero number raised to zero is always 1. We will be using these rules to find the value of the given logarithm.

The simplified form of trigonometric expression, cosec θ / sin θ + cos θ cot θ is 1.

Given,

The trigonometric expression = cosec θ / sin θ + cos θ cot θ

We have  to simplify this expression.

For that we can use trigonometric identities.

cosec θ = 1 / sin θ

cot θ = cos θ / sin θ

We can substitute the above given identities in the expression.

Then we get,

cosec θ / sin θ + cos θ cot θ = (1 / sin θ) / (sin θ + cos θ x (cos θ/sin θ))

= (1 / sin θ) / ((sin²θ + cos²θ) / sin θ)

Cancel sin θ from both numerator and denominator.

= 1 / sin² θ + cos² θ

We know that sin² θ + cos² θ = 1

So, we get,

1 / sin² θ + cos² θ = 1 / 1 = 1

Therefore, the simplified form of  cosec θ / sin θ + cos θ cot θ is 1.
