Step-by-step explanation:

Probability = Expected outcome/Total outcome

GIven

Total outcome = 28marbles

probability of randomly drawing a  blue marble = 3/7

Substitute

3/7 = number of blue marbles/28

Cross multiply

7N = 3* 28

N = 3*4

N= 12

Hence there 12 blue marbles in the bag

Answer:

See below.  Veronica's thinking is incorrect.  I've included what she is thinking, but the correct thinking is more useful, as noted below.

Step-by-step explanation:

I don't know what Veronica is thinking, other than:

(398 x 18) = (400*18 - 18)

She should be thinking:

(398 x 18) = (400 x 18) - (2*18).  The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

Answer:

Solution,

Let ,

a = 13

b = 13

c= 10

then,

s = a + b + c /2

= 13 + 13 + 10 / 2

= 36/2

= 18

Now,

Area of triangle:

\( \sqrt{s(s - a)(s - b)(s - c)} \)

\( \sqrt{18(18 - 13)(18 - 13)(18 - 10)} \)

\( \sqrt{18 \times 5 \times 5 \times 8} \)

\( \sqrt{3600} \)

\(60 \: {cm}^{2} \)

The connection string for SQL Server using Windows Authentication is as follows:

Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

Specify the server address in the format "Server=myServerAddress". Replace "myServerAddress" with the name or IP address of the SQL Server instance you want to connect to.

Specify the name of the database you want to connect to in the format "Database=myDataBase". Replace "myDataBase" with the name of the database.

Use Windows Authentication by setting "Trusted_Connection=True". This means that the user running the application is authenticated using their Windows credentials, rather than a SQL Server login.

Use semicolons (;) to separate the different parts of the connection string.

Using Windows Authentication is a more secure and convenient way to connect to a SQL Server database, as it eliminates the need to store and manage login credentials in the application.

Answer:

130

Step-by-step explanation:

x + 95 + 35 = 180

x + 130 = 180

x = 50

x + y = 180

50 + y = 180

y = 130

Answer:

130°

Step-by-step explanation:

the sum of the angles in a triangle are 180°

we need to subtract the sum of the other two angles in order to find angle ∠QPG

180-(35+95)=180-130=50°

the question is asking for the external angle of angle ∠QPG (the value that we find when we subtract the angle from 180°)

so we are going to subtract 50 from 180

180-50=130°

2nd way:

the sum of the two inner angles are equal to the external angle of the third angle:

35+95=130°--> ∠QPG

Answer:

∠1 = 137

∠2 = 43

∠3 = 137

Step-by-step explanation:

∠2 and 43 are alternate interior angles.

Alternate interior angles are equal.

So,

∠2 = 43.

∠1 and ∠3 are also alternate interior angles,

So,

∠1 = ∠3

∠1 and 42 are linear pair angles.

Sum of linear pair angles is 180,

∠1 + 42 = 180

∠1 = 180 - 43

∠1 = 137

Since,

∠1 = ∠3

So,

∠3 = 137

Hence,

∠1 = 137

∠2 = 43

∠3 = 137

Note : -

Alternate interior angles and linear pair angles are properties of angles.

Answer: 14.9

Step-by-step explanation:

The Pythagorean Theorem formula is \(a^2+b^2=c^2\). a and b are the legs, and c Is the hypotenuse. Looking at the figure, we are only given the legs, and asked to find the hypotenuse. All we have to do is to substitute and solve.

\(10^2+11^2=c^2\)            [exponent]

\(100+121=c^2\)            [add]

\(221=c^2\)                     [square root both sides]

The finite population correction factor is used in computing the standard error of the sample mean when the sample size is smaller than 5% of the population size.

The finite population correction factor is a adjustment made to the standard error of the sample mean when the sample is taken from a finite population, rather than an infinite population.

It accounts for the fact that sampling without replacement affects the variability of the sample mean.

When the sample size is relatively large compared to the population size (more than half), the effect of sampling without replacement becomes negligible, and the finite population correction factor is not necessary.

In this case, the standard error of the sample mean can be estimated using the formula for sampling with replacement.

On the other hand, when the sample size is small relative to the population size (less than 5%), the effect of sampling without replacement becomes more pronounced, and the finite population correction factor should be applied.

This correction adjusts the standard error to account for the finite population size and provides a more accurate estimate of the variability of the sample mean.

Therefore, the correct answer is option 2: the finite population correction factor is used when the sample size is smaller than 5% of the population size.

The probability of being a goalkeeper today is 0.42, or 42%.

To determine the probability of being a goalkeeper today, we need to consider the probabilities associated with each coach and their likelihood of coaching.

Given:

- Probability of being goalkeeper with Coach Sam: 0.5

- Probability of being goalkeeper with Coach Alex: 0.3

- Probability of Coach Sam being the coach today: 0.6

To calculate the probability, we can use the concept of conditional probability.

Probability of being a goalkeeper today = (Probability of Coach Sam being the coach today) * (Probability of being a goalkeeper with Coach Sam) + (Probability of Coach Alex being the coach today) * (Probability of being a goalkeeper with Coach Alex)

Substituting the given values:

Probability of being a goalkeeper today = (0.6 * 0.5) + (0.4 * 0.3)

Probability of being a goalkeeper today = 0.3 + 0.12

Probability of being a goalkeeper today = 0.42

Therefore, the probability of being a goalkeeper today is 0.42, or 42%.

Bar charts, pie charts, and stacked bar charts are commonly used for representing quantitative data.

When it comes to visually representing quantitative data, several types of charts are commonly used. One such chart is the bar chart, which uses rectangular bars of varying lengths to depict numerical values. Bar charts are effective in comparing different categories or groups and showcasing trends over time. Another popular chart is the pie chart, which divides a circle into slices to represent different proportions or percentages of a whole. Pie charts are useful for illustrating the composition or distribution of a data set. Additionally, stacked bar charts are frequently employed to display multiple variables or categories within a single bar, where each segment represents a different subset. This type of chart allows for easy comparison of subcategories while maintaining an overall total. These three chart types - bar charts, pie charts, and stacked bar charts - offer versatile options for visualizing quantitative data, enabling effective communication and analysis.

The phenomenon you mentioned is what us called Pythagoras theorem which proved to us that the square of the length of the hypotenuse of a right angled triangle, is equal to the square of the length of the opposite side to the angle in question, and also to the square of the length of the side adjacent to the same angle in question.
