The answer is False. In a finite field, for each non-zero number x, there exists a multiplicative inverse y such that x*y = 1, not 0. The only number that would satisfy x*y = 0 in a finite field is when either x or y is 0.

True. In a finite field, every non-zero element has a multiplicative inverse, meaning that there exists a number y such that x*y = 1. Therefore, if we multiply both sides by 0, we get x*(y*0) = 0, which simplifies to x*0 = 0. Therefore, for each number x in a finite field, there is a number y such that x*y = 0.
Multiplying an even number equals dividing by its difference and vice versa. For example, dividing by 4/5 (or 0.8) will give the same result as dividing by 5/4 (or 1.25). That is, multiplying a number by its inverse gives the same number (because the product and difference of a number are 1.

The term reciprocal is used to describe two numbers whose product is 1, at least in the third edition of the Encyclopedia Britannica (1797); In his 1570 translation of Euclid's Elements, he mutually defined inversely proportional geometric quantities.

In the multiplicative inverse, the required product is usually removed and then understood by default (as opposed to the additive inverse). Different variables can mean different numbers and numbers. In these cases, it will appear as

ab ≠ ba; then "reverse" usually means that an element is both left and right reversed.

Answer:

-11/3, -2.25, -3/2, 0.5

Step-by-step explanation:

p-value of the test.

To answer this question, we can use the KS Test. The KS Test is used to compare two empirical cumulative distribution functions. In this case, we can use the KS Test to compare the ECDFs of stores with above-median prices and those with below-median prices in the carseats dataset. To do this, we use the `ks.test()` function, which has two parameters - `x` and `y`. The `x` parameter represents the data from stores with above-median prices, and the `y` parameter represents the data from stores with below-median prices. The function will then return the p-value of the test.

The probability that the taxi at fault was blue 0.328125 or 32.8125%.

Probability of blue cab is

P(B) = 0.14;

Probability of green  cab is

P(G) = 0.86;

Probability of correctly distinguish is

P(C)=0.75

The probability that the witness identified a blue car is determined by the probability of the cab being blue and being correctly distinguished by the witness, added to the probability of the cab being green and being incorrectly distinguished by the witness.

P(W b) = P(B)*P(C)+P(G)*(1-P(C))

= 0.14*0.75 +0.86*0.25

=.32

The probability that a blue car is at fault is given by the probability of a blue car being correctly identified divided by the probability of a blue car being identified by the witness:

P = P(B)*P(C)/P(W b)

P = 0.14*0.75/0.32

P = 0.328125

The probability is 0.328125 or 32.8125%.

The element is remaining after 18 minutes with the rate of decaying of 26.8 % is 2.99 grams.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

An element with a mass of 820 grams decays by 26. 8% per minute.

Then the mass remaining after one minute will be

Remaining = 100 - 26.8

Remaining = 73.2 %

The element is remaining after 18 minutes will be

Mass = 820 × (0.732)¹⁸

Mass = 820 × 0.00364

Mass = 2.985

The basic unit of mass of the ball in the metric system is the gram.

The base units of length (distance), capacity (volume), and weight (mass) in the metric system are the meter, liter, and gram, respectively. We utilize units that are derived from metric units to measure smaller or greater quantities.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass.

Therefore, the basic unit of mass of the ball in the metric system is the gram.

Therefore , the solution of the given problem of standard deviation comes out to be correct option is (A)Barnsboro Bank has more variation.

Variance is measured in statistics using variance. The average variation between the data and the mean is calculated by taking the square root of that value. By comparing each value to the mean, it incorporates all data points in its computations, in contrast to some other quantitative measures of variability. Variations may occur due to internal or external factors, and they may include things like unintentional errors, exaggerated expectations, and changing commercial or economic conditions.

Here,

Given :

=> CV =S/M

is the formula used to calculate a set's coefficient of variation.

where M stands for mean and S for standard deviation.

The set's variation increases with increasing coefficient.

Barnsboro National Bank: M = 315 and S = 87, resulting in a

=> CV = S/M

= >87/315 = 0.276.

Wellington S&L = M = 8350 and S = 1800, resulting in a

=> CV = S/M

= > 1800/8350 = 0.216.

The Bank of Barnsboro has a higher coefficient and more fluctuation.

Barnsboro Bank has greater variance, which is the correct answer (A).

The process of gathering and analyzing intelligence is known as "sources and methods." The types of information obtained and the sources of that information differ.

Information collected through espionage, satellite pictures, intercepted communications, and news reports that are available to the public are all examples of intelligence sources.

The sources and procedures used by intelligence services are closely guarded since they include the means by which data is gathered and evaluated, which can be used by adversaries to determine the strengths and objectives of their foes.

The probability that the mean weight of the sample babies would differ from the population mean by less than 54 grams is 0.4339.

For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.

First, solve for the z-score using the formula below.

z-score = (x – μ) / σ

where x = individual data value = 3316 grams - 54 grams = 3262

μ = mean = 3316 grams

σ = standard deviation = 324 grams

z-score = (3262 - 3316) / 324

z-score = -54 / 324

z-score = -0.1667

Find the probability that corresponds to the z-score in the z-table. (see attached images)

z-score = -0.1667

Step-by-step explanation:

To calculate the number of Democrats and Republicans who voted for the Clean Water bill, we need to use the information provided in the question.

First, we can calculate the number of Democrats who voted for the bill by multiplying the total number of Democrats by the percentage who voted for it:

46% of 205 Democrats = 0.46 x 205 = 94.3 Democrats (rounded to the nearest tenth)

Therefore, approximately 94 Democrats voted for the Clean Water bill.

Next, we can calculate the number of Republicans who voted for the bill by multiplying the total number of Republicans by the percentage who voted for it:

48% of 230 Republicans = 0.48 x 230 = 110.4 Republicans (rounded to the nearest tenth)

Therefore, approximately 110 Republicans voted for the Clean Water bill.

Note that these are approximations since we rounded to the nearest tenth.
