Use the graph to find the average rate of change from x=-1 to x=1.

The average distance a planet is from the Sun is 9.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

Given;

Sun can be modeled by d=t^2/3, where t is the number of Earth years that it takes for the planet to orbit the Sun.

The planet has an orbit of 27 Earth years.

Now,

d=27^2/3

d^3=27^2

d=9

Therefore, by unitary method the answer will be 9.

An expression that represents the total area of Meiling's new deck is  4.3x + 29.67.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:
An architect plans to build an extension to Meiling's rectangular deck.

Let x represent the increase, in meters, of her deck's length.

The expression 4.3(x+ 6.9) represents the area of the deck,

where 4.3 is the width in meters and (x + 6.9) represents the extended length in meters.

Using the Distributive Property to write an expression that represents the total area of Meiling's new deck.

A = 4.3(x+ 6.9)

A = 4.3x + 29.67

An expression that represents the total area of Meiling's new deck is  4.3x + 29.67.

Hence, area is 4.3x + 29.67 square meters.

Anna's total earnings in a week with $2400 in sales would be $810. Her total earnings in a week with $x in sales would be $450 + ($x * 0.15).

Anna makes a guaranteed salary of $450 per week, and she earns a commission of 15% on her total sales. To calculate her total earnings in a week when she made $2400 in sales, we need to find her commission and add it to her base salary. The commission can be calculated by multiplying her total sales by 15%, which is $2400 * 0.15 = $360. Therefore, Anna's total earnings for that week would be $450 + $360 = $810.

To calculate Anna's total earnings in a week when she made $x in sales, we would follow the same process. The commission would be $x * 0.15, and this amount would be added to the base salary of $450 to determine her total earnings.

Answer:

[tex]\boxed{0} < x < \boxed{4}[/tex]

Step-by-step explanation:

The graph is y = x² - 4x

For  x² - 4x < 0 find out the interval of x
Factor x² - 4x ==> x(x - 4)

x² - 4x < 0 ==> x(x-4) < 0

Find the x-intercepts where x(x - 4) = 0

x(x - 4) = 0 means
x = 0 or x - 4 = 0
x - 4 = 0 ==> x = 4
These are critical points where the function changes sign

From the graph we see that the function has a value of 0 at x = 0 and x = 4 and is negative between 0 and 4

So the range of values for x where x² - 4x < 0 is

[tex]\boxed{0} < x < \boxed{4}[/tex]

Knowing the format of the series, such as the number of games and the requirements for series victory, is necessary to calculate the likelihood of winning the World Series (e.g., best-of-seven, first team to win four games, etc.).

Using the chance of winning any given game versus team B, which is given as 1/3, you would then need to compute the likelihood of winning each specific game.

The likelihood that team A will win the World Series may be computed as the total of the probabilities of winning each individual game, for instance, if the World Series is a best-of-seven series and team A wins each game with a probability of 1/3.

A binomial distribution, which simulates the number of successes in a certain number of Bernoulli trials with a fixed chance of success for each trial, can be used to do this.

Variables:  A = Adult tickets, C = Children tickets, S = Senior tickets

Expression for number of adult tickets sold: A = 15 + 3C

Expression for number of children's tickets sold: C = S/3

Let's define our variables:

A = Adult tickets

C = Children tickets

S = Senior tickets

We know that Joey sold 15 more adult tickets than children tickets. This means that the number of adult tickets (A) is 15 more than the number of children tickets (C). We can write this as an expression: A = 15 + C

We also know that Joey sold 3 times as many senior tickets as children tickets. This means that the number of senior tickets (S) is 3 times the number of children tickets (C). We can write this as an expression: S = 3C

Now, we can combine these two expressions to solve for the number of adult tickets sold. We can substitute the expression for S (3C) into the expression for A (15 + C) and solve for C.

Substituting 3C for S in A = 15 + C, we get: A = 15 + 3C

This expression tells us that the number of adult tickets sold (A) is equal to 15 plus 3 times the number of children tickets sold (C).

To solve for the number of children tickets sold (C), we can use the expression for S (3C). We can divide both sides of the equation by 3 to solve for C.

Dividing both sides by 3, we get: C = S/3

This expression tells us that the number of children tickets sold (C) is equal to the number of senior tickets sold (S) divided by 3.

The correct answer is (a) Yes, because  we cannot use the binomial probability the 100 adults represent less than 5% of the U.S. adult population, the trials can be treated as independent

The probability of at least 30 adults out of 100 being left-handed can be calculated using the binomial probability formula with x counting the number who are left-handed. However, option (b) is not correct because the trials can still be considered independent even if the number of successes is greater than 5% of the sample size. The condition that the number of trials should be less than 5% of the population size is used to ensure that the sampling distribution can be approximated by a normal distribution.

Option (c) is also not correct because even though the sample was selected without replacement, the size of the population is much larger than the sample size, so the effect of the sampling without replacement is negligible.

t = ln(a/y) / ln(0.5).

Answer:

So the measure of angle Y is 50 degrees.

Step-by-step explanation:

By definition, complementary angles add up to 90 degrees. So we can set up the equation:

m∠S + m∠Y = 90

We also know that m∠S = 5(m∠Y) - 210. Substituting this into the first equation, we get:

5(m∠Y) - 210 + m∠Y = 90

Combining like terms, we get:

6(m∠Y) - 210 = 90

Adding 210 to both sides, we get:

6(m∠Y) = 300

Dividing both sides by 6, we get:

m∠Y = 50

So the measure of angle Y is 50 degrees.
