40 kilograms is equal to approximately 88.1849 pounds (lbs). both are unit of measurement of weight.

The pound (lb) and kilogram (kg) are both units of measurement for weight or mass. The kilogram is the base unit of mass in the International System of Units (SI) and is defined as exactly equal to the mass of a cylinder of platinum-iridium alloy kept at the International Bureau of Weights and Measures.

One kilogram is equal to 2.20462262 pounds.To convert kilograms to pounds, you multiply the number of kilograms by  2.20462262 which is its conversion factor . So, to convert 40 kilograms to pounds, you would multiply 40 by 2.20462262 which would give you 88.1849.It's important to note that the conversion between kilograms and pounds are not exact and there may be slight variations depending on the specific application or context.

It's also important to note that the precision of the conversion result depends on the precision of the input, if you know the weight is 40 kg with 0.1kg precision, the result will be 88.1849 with the same precision.In everyday life, you may use both units depend on the context, for example, body weight is usually measured in pounds in the US, and in kg

in most other countries, where as, weight of heavy machinery or cargo is measured in tons (metric ton or imperial ton)

The result when the number 31 is increased by 8% and rounded to the nearest tenth is 33.5.

To find the result when the number 31 is increased by 8%, we can calculate 8% of 31 and add it to 31.

8% of 31 can be found by multiplying 31 by 0.08:

8% of 31 = 31 * 0.08 = 2.48

Now, we add this result to 31:

31 + 2.48 = 33.48

Rounding this answer to the nearest tenth, we get:

To determine the probability that the ball selected shows an odd number, given that the ball is yellow, we need to consider the number of favorable outcomes (yellow balls showing odd numbers) and the total number of possible outcomes (yellow balls).

From the given information, we can identify two favorable outcomes: the yellow balls numbered 3 and 5.

Therefore, the probability that the ball selected shows an odd number, given that the ball is yellow, is:

Probability = (Number of favorable outcomes) / (Number of total outcomes)

= 2 / 3

= 2/3 ≈ 0.6667

Probability that the ball selected shows an odd number, given that the ball is yellow, is approximately 0.6667 or 66.67%.

The part in the steering column that allows for changes in the angle between the upper and lower shafts is the universal joint.

The universal joint, also known as a U-joint or Cardan joint, is a mechanical device that enables changes in the angle between two shafts that are not in a straight line. In the context of a steering column, the upper and lower shafts are connected by a universal joint.

As the steering wheel is turned, it exerts rotational force on the upper shaft of the steering column. The universal joint allows for the transmission of this rotational motion while accommodating changes in the angle between the upper and lower shafts. It provides flexibility and compensates for any misalignment between the two shafts, ensuring smooth and continuous rotation of the steering column.

The universal joint typically consists of two yokes connected by a cross-shaped component with needle bearings. These bearings allow for rotation in multiple axes, allowing the steering column to handle variations in the angle between the upper and lower shafts during steering movements.

A number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

Irrational number, any real number that cannot be expressed as the quotient of two integers.

Firstly, we know that π is an irrational number .

So π x √4 = 2π

2π is an irrational number and so option A cannot represent a rational number.

2/3 + 4/3 = 6/3 = 2

Answer:

x = 122°

Step-by-step explanation:

There is remote angle( non- adjecent angle) and their sum equal to the exterior angle .

Exterior angle is an angle formed from one side of the polygone and the extended side so

<A and <B are remot angle and <BCD is exterior angle .

And we write the equetion as

<A + <B = <BCD

58° + 64° = x°

122° = X°

so the exterior angle ( x ) measures 122° .

To evaluate and simplify expressions using exponent laws, we can apply the rules and properties that govern the behavior of exponents.

By understanding and applying these laws, we can manipulate and simplify exponential expressions. In the given questions, we will evaluate the expression 64-16 using exponent laws and simplify the expression i by using only positive exponents.

a) To evaluate 64-16, we can rewrite it as (2^6) / (2^4) using the exponent law for division. According to the law of exponents, when dividing two exponential expressions with the same base, we subtract the exponents. Therefore, 64-16 = 2^(6-4) = 2^2 = 4.

b) To simplify 814 (4/5), we can rewrite it as (8^1) (14^1) (4/5) using the exponent law for multiplication. According to the law of exponents, when multiplying exponential expressions with the same base, we add the exponents. In this case, we have 8^1, 14^1, and (4/5)^(1), which all have an exponent of 1. So, the simplified expression is 8 * 14 * (4/5) = 448/5.

For the expression i, if we are referring to the imaginary unit, it does not involve exponents since it is a constant. Therefore, no exponent laws are applicable, and there is no further simplification possible.

By understanding and applying the exponent laws correctly, we can evaluate and simplify exponential expressions efficiently.

What is Percentage?

Percentage is a ratio expressed as a percentage of 100.

Total area of selling space = \(2500 ft^2\)

Percentage of space used for isles = \(30\) %

Area of space used for isles = \(\frac{30}{100} \times 2500\)

                                               = \(750 ft^2\)

Area of space left = \(2500 - 750\)

                              = \(1750 ft^2\)

Area of space reserved for each category =  \(125 ft^2\)

The amount spent on calculators is $310 which is option (b) .

It is given that half people ordered $29.95 calculator which means that 5 people have ordered $29.95 per calculator then , amount is given by

    (number of people ) × cost per calculator = total amount spent

       \(5\times29.95=\$149.75\)

It is given that least expensive calculator was $19.95 and the most expensive calculator was $39.95.

Mean will be \(=\frac{least\ + \ most}{2}\)

                      \(=\frac{19.95+39.95}{2} \\\\=\frac{59.9}{2} \\\\=29.95\)

so the other 5 people have spent an average of amount \(=5\times29.95\)

The expected number of companies that might not respond is 67.5.

Based on the given information, we can model the nonresponse rate using a binomial distribution. Let's define the following variables:

n = Number of questionnaires mailed = 150

p = Probability of not responding = 0.45

To determine the number of companies that might not respond, we can calculate the probability of different scenarios using the binomial distribution formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

X represents the number of companies that do not respond.

k represents the number of companies that do not respond.

C(n, k) is the binomial coefficient, calculated as C(n, k) = n! / (k! * (n - k)!)

To find the probability of a specific number of companies not responding, we substitute the values of n, p, and k into the formula.

For example, to find the probability that exactly 70 companies do not respond, we can calculate:

P(X = 70) = C(150, 70) * 0.45^70 * (1 - 0.45)^(150 - 70)

To find the expected number of nonresponses, we can use the formula:

E(X) = n * p

In this case:

E(X) = 150 * 0.45

So the expected number of companies that might not respond is 67.5.

Note: The binomial distribution assumes independent and identically distributed trials, so it is important to ensure that the assumption holds in the given scenario.
