Based on the calculations we have rejected the null hypothesis .

Given,

Standard deviation = $ 45

Random sample = 20

Now,

Part 1

Set the null hypothesis and alternative hypothesis,

\(H_{0} : u = 0\\ H_{0} : u > 606.40\)

Part 2

The value of z critical signifies 5% level of significance .

\(Z_{0.05} = 1.65\)

According to critical value if z after calculation is greater than or equal to 1.65 we reject the null hypothesis .

Part 3

The value of Z can be calculated by the formula,

Z = X - µ/σ/√n

Substitute the values ,

Z = 628.85 - 606.40/45/√20

Z = 1.93

Part 4

From the above calculation the value of Z is greater than the critical value .

Thus we reject the null hypothesis .

The only number that is 10 times as much as 72 is 720.

To find the numbers that are 10 times as much as 72 or 1/10 of 72, we can perform the following calculations:

10 times 72 = 720

1/10 of 72 = 7.2

So, the numbers that are 10 times as much as 72 are 720.

The number 67 is not 10 times as much as 72 or 1/10 of 72. Therefore, it is not one of the numbers we are looking for.

On the other hand, 1/10 of 72 is 7.2, which is not one of the numbers we are looking for either.

Therefore, the only number that is 10 times as much as 72 is 720.

Answer:

17.99

Step-by-step explanation:

Trig Ratios:

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Tangent

We can use trig ratio sine as we are given an angle ( 40° )and the hypotenuse (28) and we need to find its opposite side (w)

Recall that sin = opposite over hypotenuse

That being said we want to create an equation to solve for w

\(sin(40)=\frac{w}{28}\)

Now we solve for w

Step 1 multiply each side by 28

\(\frac{w}{28} *28=w\\sin(40)*28=28sin(20) = 17.99\)

we're left with w = 17.99

Answer:

(0,5)

Step-by-step explanation:

3x-5y=15

Plug in 0 for y, because we are trying to find the value of x, when y is 0

3x=15     Divide both sides by 3

x=5

so the answer in coordinate form is (0,5)

The equation x=1-2y/3y+5,  can be expressed as 3xy+2y=1-5x below:

The concept that will be used in the expression is simplification and expansion.

Given x=1-2y/3y+5

then we can cross multiply as

x(3y+5) = 1-2y

Then we can expand the equation as

3xy + 5x = 1-2y

then we can rearrange the equation as:

Now, we know that the addition is commutative.

Using commutative property, 4+x = x+4,

So,

Both numerator and denominator has same value, hence they could be cancelled.

\(\frac{x+4}{4+x}\) = \(\frac{x+4}{x+4}\)

A hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. The statement that is true is, a hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. A hypothesis is a suggested explanation of a phenomenon or observed data that is testable.

Hypotheses are more detailed, and are written to explain precisely what you think is going to occur in your research and the reason for that prediction. A hypothesis will be rejected if it does not fit the data, whereas a theory will be modified to fit the data.

A hypothesis is more like a forecast, and a theory is more like a law that explains how certain events operate. Thus, we can conclude that a hypothesis is a specific prediction arising from the theory.

       double acres = square feet / 43560;

}

In this program, we declare a double variable square feet with the value of 389,767, which represents the area of the parcel of land in square feet.

We then calculate the number of acres by dividing square feet by the constant value 43,560, which is the number of square feet in one acre. The result is stored in a double variable acres.

Finally, we output the result using the system.out.println() method, which prints a message to the console indicating the area of the land in acres.

6.908 is greater than 6.098 as the second digit from the left is greater.

We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, are two numbers 6.098 and 6.908.

Now, starting from left both the numbers have the same digit so we can't

Two algebraic expressions are combined to create an algebraic equation using the equals (=) sign. Algebraic equations are also known as polynomial equations since they contain polynomials on both sides of the equal sign. An algebraic equation consists of variables, coefficients, constants, and algebraic operations including addition, subtraction, multiplication, division, and exponentiation.

An integer or set of integers that satisfy the condition in the equation are the roots or solutions of an algebraic equation.

Let the number of people who attended the festival last year =x

Option A) 15% is the most suitable representation of the probability of an unlikely event since it falls within the valid range of 0 to 1.

To determine the probability of an event, we typically express it as a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. In this case, we are looking for the probability of an unlikely event, which means the probability value should be relatively low.

Let's analyze each option:

A) 15%:

This option represents a probability value of 15%, which can also be expressed as 0.15. Since 0.15 is greater than 0 and less than 1, it falls within the valid range for a probability value. Therefore, option A) 15% is a reasonable representation of the probability of an unlikely event.

B) 9/2:

This option represents a fraction, 9/2, which is equal to 4.5. Since 4.5 is greater than 1, it does not fall within the valid range for a probability value. Therefore, option B) 9/2 is not a suitable representation of the probability of an unlikely event.

C) 0.99:

This option represents a probability value of 0.99. Although 0.99 is close to 1, it is still greater than 0. Therefore, option C) 0.99 is not a suitable representation of the probability of an unlikely event.

D) -3:

This option represents a negative value, -3. In probability theory, probabilities cannot be negative since they represent the likelihood of an event occurring. Therefore, option D) -3 is not a valid representation of the probability of an event.

In summary, option A) 15% is the most suitable representation of the probability of an unlikely event since it falls within the valid range of 0 to 1.
