The probability that it will have distinct even digits is 6/1000.

The first digit can take on 5 values (0,2,4,6,8).

The second digit could take on 4 values (one less than 5 to be unique).

The third digit could take on 3 values (two less than 5 to be unique).

So that makes,

N=5.4.3

N=60

P= 60/1000

P=3/50

So there are 60 unique three digit even numbers.

There are 1000 possible outcomes.

Probability and statistics are two fundamental concepts in mathematics. Probability is about the probability of an event, whereas statistics are about how different techniques are used to process different data.

Probability and statistics allow us to process complex data in a very understandable way.

Probability is one of the most popular topics in statistics. The reason is that this one theory is often used when trying to predict something. For example, figuring out what comes out of a random series of events. For simplicity, probability is also called chance or probability.

The larger cup can hold 144.51 in³ more water than the smaller cup.

The volume of a cone of radius r and height h is given by one third of the multiplication of pi = 3.14 by the radius squared by the height, hence:

V = 3.14r²h/3

V = 1.0472r²h.

For the smaller cup, the dimensions are r = 2 in and h = 3 in, hence the volume is given as follows:

V = 1.0472 x 2² x 3

V = 12.57 in³.

For the larger cup, the dimensions are r = 5 in and h = 6 in, hence the volume is given as follows:

Stratified Random Sampling is used when dividing a population into subgroups so that a random sample from each subgroup can be collected. (option 3)

Stratified Random Sampling is a type of probability sampling where the population is divided into subgroups (or strata) based on some important characteristic. The purpose of stratifying the population is to ensure that each subgroup is represented in the sample, so that the results of the study can be more accurately generalized to the larger population.

After dividing the population into strata, a random sample is selected from each stratum. This approach is used when there is heterogeneity within the population and it is important to ensure that each subgroup is adequately represented in the sample. This method can result in a more precise estimate of population parameters compared to simple random sampling, as it ensures that each subgroup is proportionately represented in the sample.

The outside factor of the average property price of the local neighborhood would bias bexp in a positive direction.

This is because an increase in average property price will increase the value of the dependent variable (bexp). If the average property price of the local neighborhood increases, it will likely lead to an increase in the value of bexp.

This is because the increase in average property price will lead to an increase in the value of properties in the local neighborhood, which will in turn increase the value of bexp. Therefore, an increase in the average property price of the local neighborhood will lead to an increase in the value of bexp.

To find the mean of the data set, we will simply take the average of the data as:  Mean= 345+340+400+625/ 4=  427.5

So we have mean as, 427.5

Now we have to calculate the variance of the data.

As we know, for variance we take the difference of each value from mean, take its square and then average of all.

345-427.5 = -82.5

340-427.5 =-87.5

400-427.5 = -27.5

625-427.5 =197.5

Now

Variance=σ2 =(-82.5)^2 + (-87.5)^2 + (-27.5)^2+ (197.5)^2 /4  

σ2=6806.25+7656.25+756.25+39006.25/4

σ2=13556.25

So, the variance is 13556.2

Now we have to calculate the Standard deviation (S.D) of the data.

And the Standard Deviation is just the square root of Variance, so:

σ = √13556.25

σ =116.43

Taking into account the definition of a system of linear equations, Celia has 58 coins in her bank, 13 dimes and 45 quarters.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

In the systems of equations, the values of the unknowns must be found, with which, when replaced, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know:

So, the system of equations to be solved is

d + q= 58

0.10d + 0.25q= 12.55

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, Isolating the variable "d" from the first equation, we obtain:

d= 58 -q

Substituting in the second equation you get:

0.10× (58-q) + 0.25q= 12.55

Solving:

0.10×58 - 0.10q + 0.25q= 12.55

5.8 - 0.10q + 0.25q= 12.55

- 0.10q + 0.25q= 12.55 -5.8

0.15q= 6.75

q= 6.75÷ 0.15

q= 45

Remembering that d=58 - q, you get:

Step-by-step explanation:

The standard deviation of the sample proportions (i.e., the standard error of the proportion) is 10.5.

The sample proportion is a random variable that can't be predicted with certainty because it fluctuates from sample to sample.

n = 525

Population Proportion(p) = 0.3

q = 1 - 0.3

q = 0.7

σ = √npq

σ = √(525 × 0.3 × 0.7)

σ = √110.25

σ = 10.5

So The standard deviation of the sample proportions = σ/n

The standard deviation of the sample proportions = 10.5/525

The wechsler intelligence scale has a mean of 100 and a standard deviation of 15.  the z score that corresponds to an iq score of 115 is 1.

To calculate the Z score, you subtract the mean from the score and divide it by the standard deviation. In this case, 115-100=15, and 15/15=1.  A Z score of 1 indicates that the score is one standard deviation above the mean. This means that a score of 115 is higher than 84% of the population. It is in the top 16% of scores.

This score is considered to be in the high average range on the Wechsler Intelligence Scale.  The Z score can be interpreted in a variety of ways. It can be used to compare scores or to see how far a score is from the mean. It also can be used to compare scores across different tests.
