The students that prefer science than Maths are 27

From the question, we have the following parameters that can be used in our computation:

Math = 24

Science = 33

Total proportion = 100

The additional number of students that prefer science than Maths is calculated as

Additional = (Science - Maths)/Total proportion * Number of students

So, we have

Additional = (33 - 24)/100 * 300

Evaluate

Additional = 27

Hence, the number of students is 27

The 90% C.I. is more precise in estimating a mean than the 95% C.I.

What does confidence interval mean?

Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.

                        If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. In statistics, confidence is another word for probability.

What does the term "confidence interval" mean?

A claim of 95% confidence in statistics essentially means that the researcher has observed one conceivable interval out of many possible ones, and that 19 out of 20 of those intervals contain the correct value of the parameter.

The average rate of change of the enrollment during this time period is increasing with 48 students/year.

What is rate of change?

In 2001, there were 940 students.

In 2009, there were 1324 students.

Represent year with y and students with x.

Average rate of change = (x₂ - x₁) / (y₂ - y₁)

= (1324 - 940) / (2009 - 2001)

= 384/ 8

The equation of the red graph is x² + 2

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

Since the function in the graph is headed upward , we know the portion of  x²  is positive . And since the highest point of the red line on the y-axis is 2, we can conclude the function represented by the red line is

x² + 2

Therefore the equation of red graph is  x² + 2

The vote received by the candidate if he receives 45 % of the votes and a total of 440 votes were cast is 198.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is.

Given:

The Total vote of the election = 440,

The vote received by one candidate = 45 % of total votes,

Solve the expression as given below,

The vote received by one candidate = 45 % of 440

The vote received by one candidate = 45 / 100 × 440

The vote received by one candidate = 0.45 × 440

The vote received by one candidate = 198

Therefore, the vote received by the candidate if he receives 45 % of the votes and a total of 440 votes were cast, is 198.

Using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

In mathematics, the division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed.

For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The division sign, "," or occasionally "/," is used in computer code.

So, we know that: Total seeds are 2700 and the total rows are 9

If there are the same amount of seeds in each row.

Following that, the number of seeds will be put in each row.

= (Total seeds) ÷ (Total rows)

= 2700÷9

= 300

Therefore, using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

The percentage of all graduates who plan to enter the workforce and reside locally is 15%.

According to the tree diagram, we need to calculate the percentage of high school graduates who plan to enter the workforce and reside locally. To calculate this, we need to follow the branches in the tree diagram. Let's start from the top:

1. The first branch shows that 30% of high school graduates plan to enter the workforce.

2. From those 30%, 50% plan to reside locally.

3. To calculate the percentage of all graduates who plan to enter the workforce and reside locally, we need to multiply the percentages from steps 1 and 2 together: 30% * 50% = 0.30 * 0.50 = 0.15 or 15%.

Therefore, the percentage of all graduates who plan to enter the workforce and reside locally is 15%.

Answer: To write the equation in slope-intercept form, we need to isolate the y term on one side of the equation. We can do this by adding 4 to both sides of the equation:

y - 4 + 4 = x - 3 + 4

Combining like terms on each side, we get:

y = x - 3

This is the slope-intercept form of the equation. The slope of the line is 1, and the y-intercept is -3. The slope-intercept form of the equation is y = 1x - 3.

Answer: y = x + 1

Step-by-step explanation:

Write y - 4 =(x-3) in slope-intercept form

This is in Point Slope Form.

y - 4 =(x-3)

We add 4 to both sides

==> y - 4 + 4 = x-3 + 4

==> y = x + 1

This is slope intercept form, since it resembles the equation, y = mx + b, but m equals zero.

Thus, the domain is [tex][-3,-1) \cup (-1, 6)[/tex].

Answer: To determine which expression is equivalent to the one Shea wrote, we can first evaluate the expression 5(y + 2) + 4. The parentheses indicate that we should first perform the operation inside the parentheses, which is to add 2 to y. This results in 5(y + 2) = 5y + 10.

We can then add 4 to both sides of the equation to get 5y + 10 + 4 = 5y + 14. This expression is equivalent to the one Shea wrote, 5(y + 2) + 4.

Therefore, the expression that is equivalent to the one Shea wrote is 5y + 14.

54899.91 is the salary level that divides the teachers into one group that gets a raise and one that doesn't. Using the concept of probability -

Probability is a mathematical discipline that concerns with numerical figures of how probable an occurrence is to occur or how probably a statement is to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given that,

the salary of teachers in a particular school district is normally distributed with a mean of 50000.

standard deviation of 2500

2.5% of the salaries would not get a raise

P (X > x) = 0.025

or, P {( X - 50000)/2500} ≤ {x - 50000/2500} = 0.975

or, P (Z ≤ ( x - 50000)/2500) = 0.975

or, Φ ((x - 50000)/2500) = 0.975

or, (x - 50000)/2500 = Φ⁻¹ (0.975)

or, (x - 50000)/2500) = 1.959964

From inspection of the given triangle:

Substitute the values into the sine rule to find the measure of angle C:

[tex]\implies \dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex]

[tex]\implies \dfrac{\sin 81^{\circ}}{13.5}=\dfrac{\sin C}{8.2}[/tex]

[tex]\implies \sin C=\dfrac{8.2\sin 81^{\circ}}{13.5}[/tex]

[tex]\implies C=\sin ^{-1} \left(\dfrac{8.2\sin 81^{\circ}}{13.5}\right)[/tex]

[tex]\implies C=36.86482816..^{\circ}[/tex]

Interior angles of a triangle sum to 180°.

[tex]\implies A+B+C=180^{\circ}[/tex]

[tex]\implies 81^{\circ}+B+36.86482816...^{\circ}=180^{\circ}[/tex]

Substitute the found value of angle B into the sine rule and solve for b:

[tex]\implies \dfrac{\sin 81^{\circ}}{13.5}=\dfrac{\sin 62.13517184...^{\circ}}{b}[/tex]
