-x = -6..............so x = 6

2(6) - y = 4
12-y = 4
-8 = -y
so y = 8

inysia [295]

Answer:

D) 0.5764.

Step-by-step explanation:

According to a standard z-score table, a z-score of -0.5 corresponds to the 0.3085-th percentile of a standard normal distribution.

Furthermore, a z-score of 1.2 corresponds to the 0.8849-th percentile of a standard normal distribution.

Therefore, the area under the standard Normal curve corresponding to -0.5 < Z < 1.2 is:

A = 0.8849-0.3085\\A=0.5764

The answer is option D) 0.5764.

The game is played on a square court divided into four smaller squares that meet at the center. If a line is drawn diagonally fr
mixer [17]

Answer:

15\sqrt{2}\ ft ≈ 21.21\ ft

Step-by-step explanation:

Observe the figure attached.

You need to use the following Trigonometric function in order to find the length of the diagonal "d":

cos\alpha=\frac{adjacent}{hypotenuse}

For this case:

\alpha=45\°\\adjacent=15\\ hypotenuse=d

Therefore, you need to substitute these values into the Trigonometric function and solve for "d":

cos(45\°)=\frac{15}{d}\\\\d*cos(45\°)=15\\\\d=\frac{15}{cos(45\°)}

d=15\sqrt{2}\ ft ≈ 21.21\ ft
