The circumference of a circle is 12.56 miles. What is the circle's diameter?

Coordinates - A pair of integers that show the location of a point on a graph. The first number represents the x-axis, while the second represents the y-axis.

Other names for this type of pair are ordered pair and numbered pair. A proportionate connection is one in which the values are all connected by the same constant value. A proportionate connection is also known as a linear relationship in mathematics.

Assume f(x) and g(x) are two functions that accept a real number as input and return a real number as output.

The intersection points of f(x) and g(x) are then those x values for which f(x)=g(x).

The precise numbers can sometimes be discovered by algebraically solving the equation f(x)=g(x).

When one fails to reject a null hypothesis that is actually wrong, this error is known statistically as a type II error. This term is used in the context of hypothesis testing.

A type II error, often called an error of omission, results in a false negative. When the patient is infected, a disease test, for instance, can return a negative result. This is a type II error because, despite being wrong, we accept the test's negative conclusion.

The difference between a type I and type II error is that a type I error refers to the failure to reject a valid null hypothesis, whereas a type II error refers to the failure to do so. Despite the fact that the error does not happen by accident, it rejects the alternative theory.

The likelihood of mistakenly failing to reject the null hypothesis when it does not apply to the entire population is known as a type II error.

In essence, a type II error is a false negative.

The number of bags of oranges Noah used on Tuesday as required to be determined in the task content is; 11/20 bags of oranges.

It follows from the task content that Noah used 3 3/10 bags of oranges on Monday.

Hence, by expressing the mixed number, 3 3/10 as a fraction; we have; 33/10.

Therefore, since he uses 1/6 as many oranges as on Monday on Tuesday;

The number of bags of oranges used on Tuesday is; (1/6) × 33/10

= 33/60

= 11/20.

Therefore, the number of bags of oranges Noah uses on Tuesday is; 11/20.

The average rate of change f(x) on the interval -6 ≤ x ≥ 2 is; 5

Average rate of change is a measure of how much the function changed per unit, on average, over that interval. This is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

Now, the formula for the average rate of change over the interval (a, b) is;

f'(x) = [f(b) - f(a)]/(b - a)

Now, we are given the interval as -6 ≤ x ≥ 2.

From the given polynomial graph, we see that;

f(2) = 0 and f(-6) = 40

Thus;

f'(x) = [f(-6) - f(0)]/(2 - (-6))

f'(x) = (40 - 0)/8

f'(x) = 5

It is a whole number because the set of whole numbers includes the natural numbers plus zero. It is an integer since it is both a natural and whole number.

Answer:  rational numbers if thats an answer

Step-by-step explanation:

Using the table, we have the following points:

(x1, y1) ==> (2.5, 3), (3.5, 4.5), (5, 4.8), (5.5, 5.2), (6, 5.5)

Let's find the correlation coefficient.

To find the correlation coefficient, apply the formula:

Where:

n = 5

Σx = 2.5 + 3.5 + 5 + 5.5 + 6 = 22.5

Σy = 3 + 4.5 + 4.8 + 5.2 + 5.5 = 23

Σxy = 2.5⋅3 + 3.5⋅4.5 + 5⋅4.8 + 5.5⋅5.2 + 6⋅5.5 = 108.85

Σx² = 2.5² + 3.5² + 5² + 5.5² + 6² = 109.75

Σy² = 109.6

Plug in values in the formula and solve for r.

We have:

Therefore, the coefficient is 0.94

ANSWER:

The inverse of the function y = 2 · x² - 4 is equal to y⁻¹ = √[(x + 4) / 2], such that x ≥ - 4. (Correct choice: B)

In this problem we have a quadratic function, whose inverse has to be found. First, we make the following substitution on the function:

y = x

x = y⁻¹

Now we proceed to clear y⁻¹ by using algebra properties:

x = 2 · (y⁻¹)² - 4

x + 4 = 2 · (y⁻¹)²

(x + 4) / 2 = (y⁻¹)²

√[(x + 4) / 2] = y⁻¹

y⁻¹ = √[(x + 4) / 2], such that x ≥ - 4

The inverse of the function is equal to y⁻¹ = √[(x + 4) / 2], such that x ≥ - 4.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation of the albumin levels are given as follows:

[tex]\mu = 35, \sigma = 5[/tex]

The probability that a randomly selected adult has a serum albumin level greater than 32.5 g/l is one subtracted by the p-value of Z when X = 32.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (32.5 - 35)/5

[tex]\textsf{(b)} \quad v(t)=-8t-2[/tex]

[tex]\textsf{(c)} \quad L(t)=-26t+41[/tex]  

(d)  See attachment.

Step-by-step explanation:

Given equation for displacement:

[tex]s(t)=-4t^2-2t+5[/tex]

Average velocity formula:

[tex]\boxed{\overline{v}=\dfrac{s(t_2)-s(t_1)}{t_2-t_1}}[/tex]

where:

To find the average velocity of s(t) between the inputs t and t+h:

Find expressions for s(t) at t₁ and t₂:

[tex]\implies s(t_1)=s(t)=-4t^2-2t+5[/tex]

[tex]\begin{aligned}\implies s(t_2)=s(t+h)&=-4(t+h)^2-2(t+h)+5\\&=-4(t^2+2th+h^2)-2t-2h+5\\&=-4t^2-8th-4h^2-2t-2h+5\end{aligned}[/tex]

Substitute the found values into the average velocity formula:

[tex]\begin{aligned}\implies \overline{v} =\dfrac{s(t_2)-s(t_1)}{t_2-t_1}}&=\dfrac{(-4t^2-8th-4h^2-2t-2h+5)-(-4t^2-2t+5)}{(t+h)-t}}\\\\&=\dfrac{-4t^2-8th-4h^2-2t-2h+5+4t^2+2t-5}{t+h-t}\\\\&=\dfrac{-8th-4h^2-2h}{h}\\\\ &=-8t-4h-2\\\\ \end{aligned}[/tex]

Therefore, the average velocity between the inputs t and t+h is:

[tex]\boxed{\overline{v}=-8t-4h-2}[/tex]

To find the equation for instantaneous velocity v(t), differentiate the equation for displacement:

[tex]\begin{aligned}\implies v(t)&=s'(t)\\&=2 \cdot -4t^{(2-1)}-1 \cdot 2t^{(1-1)}+0\\&=-8t-2\end{aligned}[/tex]

Find the value of s when t = 3:

[tex]\begin{aligned}\implies s(3)&=-4(3)^2-2(3)+5\\&=-4(9)-6+5\\&=-36-6+5\\&=-42+5\\&=-37\end{aligned}[/tex]

To find the gradient of s(t) at t = 3, substitute t = 3 into the differentiated function:

[tex]\begin{aligned}\implies s'(3)=v(3)&=-8(3)-2\\&=-24-2\\&=-26\end{aligned}[/tex]

Substitute the found gradient and found point (3, -37) into the point-slope form of a linear equation to find the equation of the tangent line L(t):

[tex]\begin{aligned}\implies s-s_1&=m(t-t_1)\\s-(-37)&=-26(t-3)\\s+37&=-26t+78\\s&=-26t+41\\\implies L(t)&=-26t+41\end{aligned}[/tex]

Using synthetic division, the solution to the polynomial fraction expression is; 2x² - 10 + 12/(x - 4)

We are given the polynomial fraction as;

(2x³ - 10x + 2)/(x- 4)

This means that we want to divide the polynomial (2x³ - 10x + 2) by (x - 4) using synthetic division.

For the divisor, we have x - 4, and that means x - 4 = 0, x = 4

So, we'll be using 4 for the synthetic division and we have;

-1  |   2     0    -10   2
