irina [24]3 years ago
5 0

Answer:

I think this question is incomplete or maybe incorrect but if it's OK then the answer would be 7x + 5y.

Step-by-step explanation:

the answer remains the same because the question has no like terms so no further calculations can be made.

Find value of x PLEASE SHOW WORK!!!
kogti [31]

Answer:

the value of X is 122

Step-by-step explanation:

First, all triangle angles add up to 180 so to find the missing angle we subtract  51 and 71 from 180 and get 58

Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen
Andrews [41]

Answer:

0.044

Step-by-step explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x) p^{x} (1-p)^{n-x} for x=6

Putting in the formula ,

we get

P(x) = C(9,6) 0.9^{6} 0.1^{3}

84 X 0.531441 X 0.001

= 0.044

morpeh [17]

Step-by-step explanation:

\sqrt{1/8}=\sqrt{1} /\sqrt{8}

\sqrt{8} =2\sqrt{2}

1/(2\sqrt{2} )

if the denominator is a root then multiply itself by itself to get an integer

1(2\sqrt{2} )/((2\sqrt{2})(2\sqrt{2} ))

\sqrt{2} /4

Hope that helps :)
