Step-by-step explanation:

Area of pentagon: A = 1/2 × p × a;

where 'p' is the perimeter of the pentagon and 'a' is the apothem of the pentagon.

A = 1/2 x (6 x 5) x 3.5 = 1/2 x 30 x 3.5 = 15 x 3.5 = 52.5

The area of the regular pentagon with apothem 3.5 and side 6 is 52.5

In Mathematics, a pentagon is a polygon with 5 sides. A pentagon can be classified as a regular pentagon and irregular pentagon. When all the sides and the angles of a pentagon are of equal measure, then it is called a regular pentagon.

Given the question, we need to find the area of the regular pentagon with apothem 3.5 and side 6.

In order to find the area, the formula to calculate the area of the regular pentagon is given by:

\(\text{Area of pentagon} =\sf \huge \text(\dfrac{5}{2}\huge \text) \times s \times a\)

Now,

\(\text{Area of pentagon} =\sf \huge \text(\dfrac{5}{2}\huge \text) \times s \times a\)

\(\text{Area of pentagon} =\sf \huge \text(\dfrac{5}{2}\huge \text) \times 6 \times 3.5\)

\(\text{Area of pentagon} =52.5\)

Therefore, the area of the regular pentagon with apothem 3.5 and side 6 is 52.5

If the sample size was increased, the 95% confidence interval would decrease. A larger sample size would provide more precise and accurate data, resulting in a narrower confidence interval.

A confidence interval is a range of values within which a population parameter is estimated to lie with a certain level of confidence. It is commonly used in statistical inference to estimate the true value of a population parameter based on a sample from that population.

If the sample size was increased, the 95% confidence interval would likely decrease. This is because a larger sample size typically leads to more precise estimates and less variability in the data, resulting in a narrower confidence interval. However, the exact size of the decrease would depend on various factors such as the amount of variability in the data and the level of statistical significance chosen for the study.

Using the normal distribution and the central limit theorem, it is found that:

\(P(246 \leq \bar{x} \leq 260) = 0.5693\)

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem:

The probability of a sample mean between 246 and 260 is the p-value of Z when X = 260 subtracted by the p-value of Z when X = 246, hence:

X = 260:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{260 - 250}{8.3333}\)

\(Z = 1.2\)

\(Z = 1.2\) has a p-value of 0.8849.

X = 246:

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{246 - 250}{8.3333}\)

\(Z = -0.48\)

\(Z = -0.48\) has a p-value of 0.3156.

0.8849 - 0.3156 = 0.5693, hence:

\(P(246 \leq \bar{x} \leq 260) = 0.5693\)

To multiply these numbers, the first step is to writhe "-8" as an improper fraction, to do so, divide it by 1

Next is to solve the multiplication, to do so, first multiply the first two terms of the multiplication:

The multiplication is between two negative numbers, when you multiply two negative numbers, the minus signs cancel each other and turn into a positive value, this is called "double-negative"

Next multiply the result by the third fraction -2/5

This time you are multiplying a positive and a negative number, so the result of the calculation will be negative

Final step is to simplify the result, both 144 and 15 are divisible by 3, so divide the numerator and denominator by 3 to simplify the result to the simplest form:

Step-by-step explanation:

Probability of an experiment consists of rolling a fair 15 -sided die with an event of rolling a number divisible by 3 is P(E)=(1 /3).

As given ,

Total number of outcomes of an experiment consists of rolling a fair 15-sided die 'n'

={1, 2, 3, …., 14, 15}

=15

Number of outcomes of an event 'E' showing rolling a number divisible by 3 'n(E)'

={3,6,9,12,15}

=5

Probability of event showing rolling a number divisible by 3 'P(E)'

=(Total number of favourable outcomes)/(Total number of outcomes)

=n(E)/n

= 5/15

=1/3

Therefore, probability of an experiment consists of rolling a fair 15 -sided die with an event of rolling a number divisible by 3 is P(E)=(1 /3).

Step-by-step explanation:

There are 23 boys and 20 girls in the class who cannot read a letter or a three-letter word.

The Venn diagram is drawn as shown in the attached image, and it shows that the number of boys and girls who cannot read a letter or a three-letter word is marked as (c+d) which represents 13 boys and 8 girls.

Given:

The class has 42 students.

12 boys and 15 girls are said to know how to read three-letter words in English.

19 boys and 17 girls are said to know how to identify all letters of the alphabet.

None of the students in the class is able to write a sentence of five words if dictated to them.

There are in total 22 boys and 20 girls in the class.

     |            |              |

     |  Boys (13) | Girls (7)    |   Cannot identify all letters

     |____________|______________|

To find the number of boys and girls who cannot read a letter or a three-letter word, we need to add up the numbers in the two bottom circles:

Boys who cannot read a letter or a three-letter word: 10 + 13 = 23

Girls who cannot read a letter or a three-letter word: 13 + 7 = 20

Therefore, there are 23 boys and 20 girls in the class who cannot read a letter or a three-letter word.

n = 7

The correlation coefficient r =

r = 7(111448)-(523)(1055)/√7(46023)-(523)² × √7(430407)-(1055)²

r = 780136-551765/√322161-273529√3012849-1113025

The p value is less than 0.05 so we reject null hypothesis. There is enough evidence to show a linear correlation between budgets and gross receipts.

The angle in degrees is 873.1843.

Let the measure of the angle be θ in degrees. Therefore, the measure of the same angle in gradians is (θ × π/180).

According to the given information, the number of degrees of a certain angle added to the number of gradians of the same angle is 152.(θ) + (θ × π/180) = 152.

Simplifying the above equation, we get:(θ) + (θ/180 × π) = 152.

Multiplying both sides of the equation by 180/π, we get:

θ + θ = (152 × 180)/π2θ = (152 × 180)/πθ = (152 × 180)/(3.14)θ = 873.1843

Thus, the angle in degrees is 873.1843.

The value of f(5) When a polynomial f(x) is divided by x -5 is 4

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.

If f(x) has a remainder of 4 when divided by x - 5

Then it means that if f(x -5) = f(0)

x -5 = 0

x = 5

so if you substitute 5 into f(x) which is f(5) it will give 4

so therefore f(5) = 4

In conclusion f(5) is same as 4
