Answer:0.68

Step-by-step explanation:

Given

Total of 600 employees out of which 400 had college degree ,100 are single

and 60 were single graduates

therefore out of 100, 60 were single and rest 40 are single undergraduate

and out of 400, 60 were single graduates thus 340 are married graduate.

Now out of 600, 100 were single i.e. 500 is married

thus Probability that an employee is married and has a college degree is

=\frac{Favourable outcome }{Total outcome}

P=\frac{340}{500}=0.68

What is the probability of rolling a dice 3 times in a row and all 3 rolls landing on a number greater than 1.
inessss [21]

Answer:

0.58

Step-by-step explanation:

P1 > 1 = 5/6

P2 > 1 = 5/6

P3 > 1 = 5/6

P1*P2*P3 = 5/6*5/6*5/6

P = 0.58

Write the given expression in terms of i : √-245
tankabanditka [31]
Okay, so first things first:
i = \sqrt{-1} 

That said, no answer that has -245 is correct.

Now we just need to solve \sqrt{245}
245/5=5*49
\sqrt{5}  * \sqrt{49} = 7i*\sqrt{5}
So, that's your answer, option D.

15 POINTS !!!!
Natalija [7]
So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out. 

So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

I hope this helps you! If it does, please rate as Brainliest :D

Which expressions are equivalent to ln x 2 ln 5 ln 1? Check all that apply. 2 ln 5x ln (x 26) ln 25x ln 1 ln 25x.
Marysya12 [62]

Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.The expressions which are equivalent to the given expression are,

  • \ln25+\ln1
  • \ln25

Given information-

The expression given in the problem is,

\ln x+2 \ln 5 +\ln1

<h3>Equivalent expression-</h3>

Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.

For given expression,

\ln x+2 \ln 5 +\ln1

As the above function is the function of <em>x. </em>Thus it can be written as,

f(x)=\ln x+2 \ln 5 +\ln1

<h3>Logarithm power rule</h3>

Logarithm power rule states that the exponent of the logarithm function can transfers to front of the logarithm and vice versa. Thus,

f(x)=\ln x+ \ln 5^2 +\ln1\\&#10;f(x)=\ln x+ \ln 25 +\ln1

Now the value of \ln 1 is equal to the zero. Thus,

f(x)=0+\ln 25 +\ln1\\&#10;f(x)=0+\ln 25 +\ln1\\&#10;f(x)=\ln 25 +\ln1\\&#10;f(x)=\ln 25 +0\\&#10;f(x)=\ln 25

Hence the expressions which are equivalent to the given expression are,

  • \ln25+\ln1
  • \ln25
