Step-by-step explanation:

it is an isoceles triangle (equally long legs).

there is a right angle at W, so YW is the height of the isoceles triangle XYZ.

that means W splits XZ in half.

therefore,

ZW = XZ/2 = 38/2 = 19

Here it the question
Cerrena [4.2K]

Answer:

Variable A and variable B have a negative linear association.

Step-by-step explanation:

We are asked to find which best describes the association between variable A and variable B.

From the scatter plot we could clearly see that as the value of variable A are increasing the corresponding value of variable B is decreasing.

Also we could see that the points are linear.

Hence, the relationship that best describes variable A and variable B is:

Negative linear Association

If sinA =3/5 and A+B =90 find cosB
-Dominant- [34]

A+B=90^o\to B=90^o-A\\\\\cos B=\cos(90^o-A)=\cos90^o\cos A+\sin90^o\sin A\\\\=\cos A+1\cdot\dfrac{3}{5}=0+\dfrac{3}{5}=\dfrac{3}{5}\\\\\boxed{\cos B=\dfrac{3}{5}}

Used:\\\\\cos(x+y)=\cos x\cos y+\sin x\sin y\\\\\cos90^o=0,\ sin90^o=1

Other method:

Look at the picture.

\sin\theta=\dfrac{opposite}{hypotenuse}\\\\\sin A=\dfrac{3}{5}\to opposite=3\ and\ hypotenuse=5

\cos\theta=\dfrac{adjacent}{hypotenuse}\\\\adjacent=3\ and\ hypotenuse=5\to\cos B=\dfrac{3}{5}

Solve for N, <br><br> −2p + 6n = 5
topjm [15]

Answer:

n=\frac{1}{3}p+\frac{5}{6}

Step-by-step explanation:

In this question, you are solving for n.

Solve:

−2p + 6n = 5

We have to get "n" by itself, so add 2p to both sides.

6n = 2p + 5

Since the variable "n" has a number next to it, we have to get rid of that number in order to get our answer.

To do so, we would divide both sides by 6.

n=\frac{2}{6}p+\frac{5}{6}

Simplify the equation further.

n=\frac{1}{3}p+\frac{5}{6}
