Answer:

\(3 \sqrt{5} \)

Step-by-step explanation:

Solve using Surd

\( \sqrt{45} = \sqrt{9 \times 5} \\ = \sqrt{ {3}^{2} \times 5 } \\ = 3\sqrt{5} \)

The expression 3√5 will be equivalent to a square root of 45.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the expression √(45)

⇒ √(9×5)

⇒ √(3²×5)

⇒ √(3²)√(5)

Since the square root of a square is the same number

We can conceptually isolate the strength of the evidence from the prior probability of the theory when we make observations first or form our hypotheses first. Correct option is C.

The concept of isolating the strength of evidence from the prior probability of the theory is known as Bayesian inference, which involves updating our prior beliefs about a theory or hypothesis based on the observed evidence.

This process can be done whenever we have some initial prior belief about the theory or hypothesis and then collect new evidence to test it.

In Bayesian inference, the strength of evidence is measured by the likelihood of the observed data given the theory or hypothesis, and the prior probability is the initial belief or probability assigned to the theory or hypothesis before the evidence is considered.

By combining these two sources of information, we can calculate a posterior probability or updated probability of the theory or hypothesis given the observed evidence.

Therefore, the answer is c) whether we make observations first or form our hypotheses first. The order in which we collect the evidence or form hypotheses does not affect our ability to conceptually isolate the strength of the evidence from the prior probability of the theory, as long as we use Bayesian inference to update our beliefs.

To solve this system of equations by elimination, we need to eliminate one of the variables (either x or y) by adding or subtracting the equations.

In this case, we can eliminate x by multiplying the first equation by 2 and subtracting it from the second equation:

2x - 6y = 12    (original second equation)

-2(x - 3y = 7)  (original first equation multiplied by -2)

-----------------

0x - 12y = -2

Now we have a new equation, 0x - 12y = -2, that relates only to y. Solving for y, we get:

0x - 12y = -2

-12y = -2

y = 1/6

Substituting this value of y back into either of the original equations, we can solve for x:

x - 3y = 7

x - 3(1/6) = 7

x - 1/2 = 7

x = 7 + 1/2

x = 15/2

Therefore, the solution to the system of equations is x = 15/2 and y = 1/6.

Answer:      (-4,-8)

Step-by-step explanation:

The amount invested in each company is :

Using the simple interest relation:

Simple interest = principal × rate × time

Total amount = 10000

Let :

principal invested in PP = r

HENCE, amount invested in TT = 10000 - r

Total interest earned on both investments = $620

PP investment return + TT investment return = 620

(r × 10% × 1) + (10000 - r × 5% × 1) = 620

0.1r + 500 - 0.05r = 620

0.05r = 620 - 500

0.05r = 120

r = 120 / 0.05

r = 2400

Hence,

Amount invested in PP = $2400

Amount invested in TT = $(10000 - 2400) = $7600

The values of x and y of the parallelogram PQRS are x = 2 and y = 11

We're given the dimensions of parallelogram PQRS as;

PT = y

TR = 5x + 1

QT = 2y

TS = 6x + 10

T is the intersection of the two diagonals PR and QS and so the diagonals bisect each other.

The diagonal PR is cut into PT and TR, both of which are congruent or equal. Thus, PT = TR.

Similarly, the other diagonal QS is split in half as well. The two equal pieces are QT and TS. So QT = TS.

PT = TR

y = 5x + 1

and

QT = TS

2y = 6x + 10

Plugging the values gives;

2y = 6x + 10

2(y) = 6x + 10

2(5x + 1) = 6x + 10

2*5x + 2*1 = 6x + 10

10x + 2 = 6x + 10

10x + 2 - 6x = 6x + 10 - 6x

4x + 2 = 10

4x + 2 - 2 = 10 - 2

4x = 8

4x/4 = 8/4

x = 2

If x = 2, then y is...

y = 5x+1

y = 5*x+1

Answer:

a = 3

Step-by-step explanation:

Since x = 7 is a solution, substitute x = 7 into the equation and solve for a

4(7) - 2(7 + a) = 8 , that is

28 - 2(7 + a) = 8 ( subtract 28 from both sides )

- 2(7 + a) = - 20 ( divide both sides by - 2 )

7 + a = 10 ( subtract 7 from both sides )

a = 3

The probability that an even number or a number greater than 3 is rolled on a 12-sided die is 0.833.

A 12-sided die has 12 equally likely outcomes, numbered from 1 to 12. To find the probability of rolling an even number or a number greater than 3, we need to count the number of outcomes that satisfy this condition and divide it by the total number of possible outcomes.

There are 6 even numbers on a 12-sided die, namely 2, 4, 6, 8, 10, and 12, and there are 9 numbers greater than 3, namely 4, 5, 6, 7, 8, 9, 10, 11, and 12. However, we need to be careful not to count the numbers that satisfy both conditions twice, namely 4, 6, 8, 10, and 12.

Therefore, the number of outcomes that satisfy the condition is 6 + 9 - 5 = 10. The probability of rolling an even number or a number greater than 3 is therefore 10/12, which simplifies to 5/6 or approximately 0.833.

The probability of getting 4 coins showing heads and 1 showing tails is approximately 15.625%.

When throwing the 5 identical coins, there are a total of 32 possible outcomes. This is because each coin has 2 possible outcomes (heads or tails), and since there are 5 coins, we multiply 2 by itself 5 times \((2^5 = 32).\)

To determine the probability of getting 4 coins showing heads and 1 showing tails, we need to calculate the number of favorable outcomes. In this case, we have 5 different ways to choose which coin shows tails (since there are 5 coins), and for each of those choices, there is only 1 possible outcome where that specific coin shows tails and the other 4 coins show heads.

So, the probability of getting 4 coins showing heads and 1 showing tails is 5/32.

To calculate the probability as a decimal or percentage, we simply divide 5 by 32:
5/32 ≈ 0.15625 ≈ 15.625%

Therefore, the probability of getting 4 coins showing heads and 1 showing tails is approximately 0.15625 or 15.625%.

The range of possible distances from the beach to the theater is 2 km to 16 km, calculated by subtracting the distance between the theater and the house (7 km) from the distance between the beach and the house (9 km), and adding it back.

To calculate the range of possible distances from the beach to the theater, we can use the information provided

Start with the distance between the beach and the house: 9 km.

Subtract the distance between the theater and the house: 7 km.

9 km - 7 km = 2 km.

This gives us the minimum possible distance from the beach to the theater: 2 km.

Add the distance between the theater and the house: 7 km.

9 km + 7 km = 16 km.

This gives us the maximum possible distance from the beach to the theater: 16 km.

Therefore, the range of possible distances is from 2 km to 16 km.

The margin of error for the survey is 0.053.

To calculate the margin of error, we need to use the formula:

Margin of Error = Critical Value x Standard Error

We can start by finding the critical value using a z-table. For a 95% confidence interval, the critical value is 1.96.

Next, we need to calculate the standard error. The formula for the standard error of a proportion is:

Standard Error = \(\sqrt{(p*(1-p))/n}\)

where p is the sample proportion (0.372) and n is the sample size (500).

Standard Error = \(\sqrt{(0.372*(1-0.372))/500}\) = 0.027

Now that we have the critical value and the standard error, we can calculate the margin of error:

Margin of Error = 1.96 x 0.027 = 0.053

Therefore, the margin of error for the survey is 0.053 or approximately 5.3%. This means that we can be 95% confident that the true proportion of people who watched the Avalanche game in the entire state of Colorado is within 5.3% of the sample proportion of 37.2%.

The measure of angle fge is 53.13°.

The equation used to find the measure of angle fge is the Law of Cosines. The Law of Cosines states that for any triangle, the square of the length of any side is equal to the sum of the squares of the other two sides, minus twice the product of those sides and the cosine of the angle opposite the side.

Using the Law of Cosines, we can solve for the measure of angle fge as follows:

\(fge = cos-1((a^2 + b^2 - c^2) / 2ab)\)

For example, if the length of side a is 3, the length of side b is 4, and the length of side c is 5, then the measure of angle fge can be calculated as follows:

fge =\(cos-1((3^2 + 4^2 - 5^2) / 2(3)(4))\)

No, the Normal/large sample condition is not met for constructing at confidence interval. Option C.

To estimate the amount of carbon emissions released by cars, the mean weight of cars must be estimated. In this case, a random sample of 20 cars is selected and their mean weight is calculated. The conditions for constructing a confidence interval are met if the following conditions are satisfied:
1. Random Condition: The sample is randomly selected.
2. 10% Condition: The sample size is less than 10% of the population size.
3. Normal/Large Sample Condition: The sample size is large enough (usually n≥30) for the Central Limit Theorem to apply, or the population distribution is approximately normal.
In this scenario, the random condition is met since the cars are randomly selected. The 10% condition is also met, assuming there are more than 200 cars in the population. However, the Normal/large sample condition is not met since the sample size of 20 is less than the recommended threshold of 30.
