how do you find the area of this problem ​

Answer:

C: p < 0.01

Step-by-step explanation:

We are given;

Spearman rank Correlation Coefficient: rs = 0.53

sample size: n = 13 pairs

Now, from the table attached, tracing n = 13 and locating a corresponding value of rs = 0.53 which falls in between 0.484 and 0.56. Thus, we can see that p is greater than the nominal significance value of 0.05 but less than 0.01.

Thus, correct answer is p < 0.01

Answer:

The answer is 2/5.

Step-by-step explanation:

First, use the stay-switch-flip method. Keep 1/5 the same, switch the division sign into a multiplication sign, and flip the numerator and the denominator of 1/2 to get 1/5 x 2/1. Multiply the numerators. 1 x 2 = 2. Now, multiply the denominators. 5 x 1 = 5. Therefore, you're answer is 2/5.

Answer:

  y ≈ 12.3

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to help you remember the relationship between trig functions and side of a right triangle. In particular, when the adjacent side and hypotenuse are involved, the desired relation is ...

  Cos = Adjacent/Hypotenuse

  cos(35°) = y/15

  y = 15·cos(35°)

  y ≈ 12.3

Answer:

v = 80 cubic units

Step-by-step explanation:

The formula for a rectangular prism is: v = lwh

l = length

w = width

h = height

v = 8 x 2 x 5

v = 16 x 5

v = 80

The equivalent complex expression of [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex] is

[tex]\frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

The correct answer is an option (b)

"The number of the form a + ib, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex]"

"This theorem gives a formula for computing powers of complex numbers.

[tex](r(cos\theta+i~sin\theta))^n=r^n~(cos(n\theta)+i~sin(n\theta))[/tex] "

For given question,

We have been given a complex expression [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex]

Using the DeMoivre's theorem,

[tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5\\\\=(\frac{1}{2})^5~((cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5\\\\=\frac{1}{32} (cos(\frac{5\pi}{5} )+i~sin(\frac{5\pi}{5} )) )\\\\= \frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

Therefore, the equivalent complex expression of [tex](\frac{1}{2}(cos(\frac{\pi}{5} )+i~sin(\frac{\pi}{5} )) )^5[/tex] is

[tex]\frac{1}{32} (cos(\pi)+i~sin(\pi))[/tex]

unless Either X's value is given for u to get y.

All pairs such that x is > 4 and y = 6 are solutions.

It is given that ordered pair is a solution to the inequality 7x-3y>10.

What is inequality?

The definition of inequality is a difference in size, amount, quality, social position or other factor.

Now, characterize these solutions

if 7x - 3y > 10 then

7x > 10 +3y

Now we can substitute any value for y and get the appropriate value for x. For example I can choose y to be 6

then by substitution

7  must be > 10+ 3*6

or 7x must be > 28

or x must be > 4

So, all pairs such that x is > 4 and y = 6 are solutions.

Answer:

[tex]\mathrm{Domain\:of\:}\:4\sqrt{t}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:t\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

The graph is also attached below.

Step-by-step explanation:

Given the expression

[tex]f\left(t\right)=\sqrt{t}\:+3\sqrt{t}[/tex]

We know that the domain of a function is the set of inputs or argument values for which the function is real and defined.

We know that we can not have a negative value of 't' inside the radicals because if we put any negative number inside the radical expression, it would make the function undefined.

In other words,  the value of t ≥ 0.

Therefore, the function domain is:

[tex]\mathrm{Domain\:of\:}\:4\sqrt{t}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:t\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

First to solve find the slope using the formula, [tex]\frac{10+10}{-5-5}[/tex]. The slope equals 20/-10 or -2. Then plug the slope and point, (-5,10), into slope-point form. y-10=-2(x+5), then solve for y. This gives you y=-2x+0 or y=-2x.

There is some disagreement over whether the "imaginary part" includes the factor "i" or not. Here, we assume it is simply the coefficient of i.

Answer:

T5 = 512

Step-by-step explanation:

Given the sequence

2,8, 32, 128,...

The sequence is a geometric progression

nth term of a geometric progression is expressed as:

Tn = ar^n-1

a is the first term = 2

n is the number of terms = 5 (next term is the 5th term)

r is the common ratio = 8/2 = 32/8 = 4

Substitute and get the fifth term

T5 = 2(4)^5-1

T5 = 2(4)^4

T5 = 2*256

T5 = 512

Hence the next term is 512

Step-by-step explanation:

From the question we are told that

Temperature is given [tex]T ( x, y, z) = x + yz.[/tex]\

A fly is at (1,2,1)

Generally the direction of fly is given by

      [tex]\triangleT(x,y,z) =(1,z,y)\\[/tex]

       [tex]v= \triangleT(1,2,1)\\v=(1,1,2)[/tex]

Mathematically solving for the vector direction

       [tex]|v|=\sqrt{1^2+1^2+2^2}[/tex]

       [tex]|v|=\sqrt{6}[/tex]

       [tex]u=- \frac{v}{|v|}[/tex]

       [tex]u= -\frac{1}{\sqrt{6}} ,-\frac{1}{\sqrt{6}} ,-\frac{2}{\sqrt{6}}[/tex]
