Answer:

x = 22

Step-by-step explanation:

Add the expressions for the angle measures.

5x + (3x + 4) + (3x + 4) + 5x = 360

Combine like terms.

16x + 8 = 360

Subtract 8.

16x = 352

Divide by 16.

x = 22

Answer:

22⁰

Step-by-step explanation:

5x + 3x + 4 + 3x + 4 + 5x = 360⁰

=> 16x + 8 = 360

=> 16x = 360 - 8

=> 16x = 352

=> x = 352/16

=> x = 22

Hence,

Value of x is 22⁰

Infinite Solutions

Step-by-step explanation:

To solve for this problem, we want to isolate x on one side of the equation.

Apply the distributive property on the right side:

\(3x - x - 5 = 2x+4 -9\)

Combine like terms:

\(2x - 5 = 2x - 5\)

Woah, we have the exact same thing on both sides of the equation. This means that we have infinite solutions, aka any value of x will satisfy this equation.

Test it out! Any value of x, whether its 1, 5, or 10000 will satisfy the equation.

So this has infinite solutions.

The equation in standard form representing the scenario where Briana has $3 in her piggy bank and has all quarters and dimes, using x for the number of quarters and y for the number of dimes, is \(25x + 10y = 300\).

Let x be the number of quarters and y be the number of dimes Briana has in her piggy bank.

The value of each quarter is 25 cents or 0.25 dollars, and the value of each dime is 10 cents or 0.10 dollars. Therefore, the total value of the coins in Briana's piggy bank can be expressed as:

\(0.25x + 0.10y\)

Since Briana has $3 in her piggy bank, we can set up the following equation:

\(0.25x + 0.10y = 3.00\)

To write this equation in standard form (\(Ax + By = C\)), we need to clear the decimals by multiplying both sides of the equation by 100:

\(25x + 10y = 300\)

Therefore, the equation in standard form that represents this scenario is:

\(25x + 10y = 300\)

Answer:

1/9

Step-by-step explanation:

Because

P(both socks are white)= 2/18

The probability of mistakenly rejecting the restaurant owner's claim if it is true is 14.28% (or 0.1428).

This can be calculated using the binomial distribution formula:

P(X >= 18) = 1 - P(X < 18)

where X is the number of tourists who stay longer than 2 days.

Assuming the restaurant owner's claim is true, the probability of a tourist staying longer than 2 days is 0.15.

Therefore,

P(X < 18) = binomdist(17, 100, 0.15, TRUE) = 0.8572

Substituting into the first equation, we get:

P(X >= 18) = 1 - 0.8572 = 0.1428

So the probability of mistakenly rejecting the restaurant owner's claim if it is true is 14.28%.

To answer this question, we need to use hypothesis testing.

Null hypothesis (H0): Only 15% of visiting tourists stay for more than 2 days.

Alternative hypothesis (Ha): The percentage of tourists staying for more than 2 days is higher than 15%.

We are given that the chamber of commerce volunteer plans to survey 100 tourists and will speak up if at least 18 of them stay longer than 2 days. This means that our test statistic is the number of tourists who stay longer than 2 days, which follows a binomial distribution with parameters n = 100 and p = the true percentage of tourists who stay longer than 2 days.

To calculate the probability of mistakenly rejecting the null hypothesis if it is true (also known as the type 1 error rate or alpha), we need to assume a significance level. Let's assume a significance level of 0.05 (or 5%).

Using a binomial calculator, we can find the probability of observing at least 18 tourists who stay longer than 2 days under the null hypothesis:

P(X >= 18 | n = 100, p = 0.15) = 0.088

This means that there is an 8.8% chance of mistakenly rejecting the restaurant owner's claim if it is true.

Therefore, the answer is 8.8% or 0.088 (rounded to three decimal places).

It should be emphasized that this suggests that we are 90% certain that the mean GPA for all students at the institution is between 3.14 and 3.52

Sampling

If the confidence level were raised to 99%, something would happen to the interval's length, increasing it.

The difference between a 90% confidence interval based on a 200-person sample and the original 90% interval is that the latter is narrower.

To solve the expression "5 (5/2) + 2 (3/5)", we'll first simplify each term inside the parentheses, then add them up:

5 (5/2) = 5 * (5/2) = 5 * 2.5 = 12.5

2 (3/5) = 2 * (3/5) = 2 * 0.6 = 1.2

Now we can add the two terms:

12.5 + 1.2 = 13.7

So the expression "5 (5/2) + 2 (3/5) = 13.7".

The distance between ping's home to aris's home will be 1 street and 12th avenue.

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,

Ping house ⇒ 3rd street and 6th avenue

Ari's home ⇒  21st street and 18th avenue

So, the distance between them

Answer:

(3x - y)(x + 7y)

Step-by-step explanation:

Given

(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = 2x + 3y and b = x - 4y , then

The two equations that represent a shift of the graph are  y=(x-12)³ and y=(x+8)³.

What is an equation?

Variable terms are frequently used in complex algorithms to reconcile two opposing claims. Academic statements known as equations are used to express the equivalence of different academic quantities. Rather than using a specific algorithm to divide 12 into two parts and assess the data obtained from y + 7, normalization in this case leads to b + 7.

The two equations describe a shift of the graph of the parent equation on the coordinate plane towards the right.

Answer:

let the two numbers = x and y

according to the statement : x-y=4

x+y=22

by elimination method: 2x=26

x=13

so... y = 13-4=9

Answer:

The two numbers (x and y) are 13 and 9 respectively. 13 minus 9 is 4 and 13 plus 9 is 22.

Step-by-step explanation:

Let the two numbers be x and y.

The difference between x and y (x - y) = 4. (eqn 1)

Their sum (x + y) = 22. (eqn 2)

From eqn 1, we can get that x = 4 + y

Substituting x as (4 + y) in eqn 2 gives the following:

(4+y) + y = 22

4 + 2y = 22

and 2y = 22 - 4

2y = 18

dividing both sides by 2 gives y = 9.

Substituting y as 9 in eqn 1 gives

x - 9 = 4

x = 4 + 9

x = 13

The expression for the area under the graph of the function \(f(x) = 4 + sin^2(x)\), where 0 ≤ x ≤ A, using right endpoints as a limit is given by the sum of the areas of rectangles with width A/n and height \(f(x_i)\), where  \(x_i = i(A/n)\)  for i = 1 to n.

To find the expression for the area under the graph of f(x), we divide the interval [0, A] into n subintervals of equal width A/n. We use right endpoints to determine the height of each rectangle. In this case, the height of each rectangle is given by \(f(x_i)\), where \(x_i = i(A/n)\) for i = 1 to n. The width of each rectangle is A/n. Therefore, the area of each rectangle is \([(A/n) * f(x_i)]\)

To find the total area, we sum up the areas of all the rectangles. This can be expressed as the limit as n approaches infinity of the sum from

i = 1 to n of \([(A/n) * f(x_i)]\). Taking the limit as n goes to infinity ensures that we have an infinite number of rectangles and that the width of each rectangle approaches zero. This limit expression represents the area under the graph of f(x) using right endpoints.
