What is the approximate area of the unshaded region under the standard normal curve below? Use the portion of the standard norma
Harlamova29_29 [7]

The approximate area of the unshaded region under the standard normal curve is 0.86 the option third is correct.

It is given that the standard normal curve shows the shaded area in the curve.

It is required to find the approximate area of the unshaded region under the standard normal curve.

<h3>What is a normal distribution?</h3>

It is defined as the continuous distribution probability curve which is most likely symmetric around the mean. At Z=0, the probability is 50-50% on the Z curve. It is also called a bell-shaped curve.

In the curve showing the shaded region area between:

\rm P(1 < Z < 2)

First, we calculate the shaded region area:

From the data given the value of Ф(1) = 0.8413.

P(Z<1)  = 0.8413  and

P(Z<2) =  0.9772

The area of the shaded region:

= P(Z<2) - P(Z<1)

=  0.9772 - 0.8413

= 0.1359

The area of the unshaded region:

= 1 - The area of the shaded region  ( because the curve is symmetric)

= 1 - 0.1359

= 0.8641 ≈ 0.86

Thus, the approximate area of the unshaded region under the standard normal curve is 0.86 the option third is correct.

In the diagram, the length of segment BC is 23 units.
timurjin [86]

Both sides should be the same length..

Since we know that BC = 23 you need to find the value of x and put it in the formula.

23 = 2x+7

16 = 2x

x = 8

4x + 1 + 4(8) + 1 = 33 units

Can you answer these please! I really need help! And I'm so not even joking only 16 17 18 and 19

16.) 38.25= 4.25h
divide by 4.25 on both sides
       h=9
17.)214= 1/3x
divide by 1/3 on both sides
x= 642
18.)70= 2x
divide by 2 on both sides
x=35
19.)18.69= 5.25+1.68x
subtract 5.25 on both sides
13.44=1.68x
divide by 1.68 on both sides
x=8

Which of these angles can replace x in tan (x)?
Alex17521 [72]

Answer:

C. φ

Step-by-step explanation:

tan \phi \:  =  \frac{6}{5}  \\  \\ tan x \:  =  \frac{6}{5}  \\  \implies \: x =  \phi

Thus \Phi can replace x
