X 4 6 9 11 15

Kitty [74]

The mean of this discrete random variable is 7.96

Solution:

Given that,

x 4 6 9 11 15

P(x) 0.20 0.34 0.15 0.22 0.09

Mean is given as:

$\mu_{x}=\sum[x \times P(x)]$

Therefore,

$\mu_{x} = (4 \times 0.20) + (6 \times 0.34 ) + (9 \times 0.15 ) + (11 \times 0.22 ) + (15 \times 0.09)\\\\Simplify\\\\\mu_{x} = 0.8 + 2.04 + 1.35 + 2.42 + 1.35\\\\\mu_{x} = 7.96$

Thus, mean of this discrete random variable is 7.96

Solve for x. Round measures to the nearest tenth

Stels [109]

Hello,

*I will move straight to the math. If you have questions, ask away! :)
* All calculations are in “degree mode” for a TI calculator or other calculator.

I will apply Laws of Sines/Cosines and inverse functions for your math.

Answer:

x= 70

Step-by-step explanation:

AB= 180 so u add 20+ 50 and then substract that to 180 which leaves you with 110. The angles are the same on both sides so the other angle is also 110, leaving x to be 70°

hope this is correct lol :)
