Answer:

Answer: 200

Step-by-step explanation: 200 doubled would be 400 and it says that tonights attendence was 100 more than the doubled which would add up and equal 500 (400+100=500) so 200 is your answer.

what are the steps for multiplying monomial algebraic terms where they have exponents with like bases

Of all postsecondary degrees awarded in the United States, including master's and doctorate degrees, 21% are associate's degrees, 58% are earned by people whose race is White, and 12% are associate's degrees earned by Whites. What is the conditional probability that a degree is earned by a person whose race is White, given that it is an associate's degree

**Answer:**

A. -0.87

**Step-by-step explanation:**

The correlation coefficient is a measure of the strength and nature of the linear relationship between two variables, one dependent and one independent. This coefficient takes values between -1 and 1, indicating with its sign whether the relationship is direct or inverse between the variables involved and with its absolute value indicates the strength of the linear relationship between them. A coefficient with absolute value close to 1 indicates great strength and better fit.

Conclusion: The best coefficient, of the propuetso in the problem, is that of -0.87, which indicates a strong relationship between the variables, a good fit and an inverse relationship between them.

Sorry it took a long time.

**Answer:**

Thor is the best deal.

**Step-by-step explanation:**

Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.

For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.

For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.

For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.

Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.

Hope this helped!

**Answer:**

**Answer:**

The function y must be decreasing (or equal to 0) on any interval on which it is defined.

**Step-by-step explanation:**

The derivative of a function gives us the rate at which that function is changing. In this case, -y^2, yields a negative value for every possible value of y, thus, the rate of change is always negative and** the function y is decreasing (or equal to 0) on any interval on which it is defined.**

The **differential** equation y' = - implies that y is either decreasing or constant wherever it is defined, because the derivative y' is non-positive.

By examining the differential equation y' = -, we can infer some characteristics about the solutions without solving it. If *y* is a solution to this equation, then y' represents the **derivative **of *y* with respect to *x*. This derivative tells us about the rate of change of the function *y*.

Since the right side of the equation is -, and a square of a real number is always non-negative, multiplying by -1 makes it non-positive. This implies that the derivative *y'* is either less than or equal to zero. Therefore, wherever the function *y* is defined, it must be either decreasing or constant (equal to zero). If *y* is positive, *y* will decrease because of the negative sign in front of the square. If *y* is negative, squaring it results in a positive number, but the negative sign still ensures that the rate of change is non-positive.

Conclusion: the function *y* is decreasing or remains constant on any interval it is defined; it cannot be increasing.

**Answer:**

10

**Step-by-step explanation:**

26×3=78

78÷8=9.75

round up to 10 since you can't buy .75 of a pizza

**Answer:**

**Step-by-step explanation:**

(4 + 9x)^3 represents "the cube of the sum of 4 and 9 times x"

and if we divide by "the product of 5 times x and the difference of x and 1," we get

(4 + 9x)^3

5x(x - 1)

What exactly do you need to know, or to do?

The correct set of **hypotheses **for the **sample** in July is H0: μ ≠ 80 Ha: μ = 80.

The** null hypothesis** H0 which is also known as the default hypothesis states that there is no relationship between the population parameters. The **alternative hypothesis** (H1 ) states that there is a relationship between the population parameters.

To learn more about the **null hypothesis,** please check: brainly.com/question/4454077

Answer:

u <= 80

u > 80

Step-by-step explanation:

The happiest would be

Null hypothesis: u <= 80

Alternative hypothesis: u > 80
