1. Normal Distribution --> Z ~ (0,1^2)

2. Use normalcdf(lower bound, upper bound, μ, σ) function on a graphing calculator

P(Z≥103.53) = normalcdf(103.53, 1e99 [default], 80, 13)

P(Z≥103.53) ≈ 0.03

3. μ+σ ≈ 13.59% According to Z-distribution chart

80+13=93

So about 93 exceed only the top 16% (estimated answer not exact)

Find the missing angles.

8_murik_8 [283]

Answer:

<em>From left to right: 54 deg, 51 deg, 47 deg</em>

Step-by-step explanation:

From the bottom right triangle:

105 + 28 + x = 180

x + 133 = 180

x = 47

The lower right triangle has angles measuring 28, 105 and 47.

The lower unknown angle of the upper right triangle is vertical to the 47 deg angle, so it also measures 47 deg.

Now we calculate the upper unknown angle of the upper triangle.

82 + 47 + y = 180

y + 129 = 180

y = 51

One angle forms a linear pair with the 105-deg angle. It measures

180 - 105 = 75.

The large left triangle has angles 75 deg, 51 deg, and the unkown angle at the left.

z + 51 + 75 = 180

z + 126 = 180

z = 54

Prove the identity. (tanx+1)^2=(1+2sinxcosx)/(cos^2x)

SOVA2 [1]

$(\tan x+1)^2=\tan^2x+2\tan x+1$
$=\sec^2x+2\tan x$
$=\dfrac1{\cos^2x}+2\dfrac{\sin x}{\cos x}$
$=\dfrac1{\cos^2x}+\dfrac{2\sin x\cos x}{\cos^2x}$
$=\dfrac{1+2\sin x\cos x}{\cos^2x}$

In the accompanying diagram, parallelogram ABCD has

Taya2010 [7]

Answer:

The area of the paralellogram is 24 square units.

Step-by-step explanation:

Geometrically speaking, the area of the parallelogram has an equation equivalent to the area formula for a rectangle, that is:

$A = b\cdot h$ (1)

Where:

$A$ - Area.

$b$ - Base.

$h$ - Height.

The base and height of the parallelogram are, respectively:

Base

$b = 8-2$

$b = 6$

Height

$h = 5-1$

$h = 4$

Then, the area of the parallelogram is:

$A = (6)\cdot (4)$

$A = 24$

The area of the paralellogram is 24 square units.
