Adding or subtracting a constant from each value of a distribution changes the mean, but not the standard deviation.

The standard deviation will equal 3.

Please find the complete question in the attached file.

The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.

The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:

$C^2=A^2+B^2$

And even those squares do verify the equation:

$169 = 144 + 25$

So, it's a rectangular (right) triangle, with sides spanning $5, 12, \ and \ 13.$

Can u help me pls<br> I don”t know what to do

Sloan [31]

Answer:

Step-by-step explanation:

Do you know SOHCAHTOA

Sin = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

#1

We have to find cos(x) = adjacent/hypotenuse

$cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}$

#2:

We are given an angle of 30 degrees and an opposite side of 15

We need to find the adjacent side, so we can use Tangent

$tan(30) = \frac{15}{adj}$

$adj = \frac{15}{tan(30)} = 25.98 = 26$

#3

We are given an angle and an opposite side and we have to solve for hypotenuse.

We can use sin

$sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5$

#4:

We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent ( $tan^-1(x)$ , but not 1/tan(x))

$tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759$

#5

We are given an opposite side and the hypotenuse, we can use sin

$sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43$
