Answer:

A and B are independent events if P(A ∩ B) = 0.06

Step-by-step explanation:

Two events A and B are independent if the probability of occurrence of A does not influence the occurrence of B.

Mathematically it is written that A and B are independent events if and only if:

P(A ∩ B) = P(A)P(B)

We know that:

P(A) = 0.20

P(B) = 0.30

Then A and B are independent if:

P(A ∩ B) = (0.20)(0.30)

P(A ∩ B) = 0.06

Finally A and B are independent events if P(A ∩ B) = 0.06

A factory whistle blows every 30 minutes. The clock tower chimes every 15 minutes. If they both sounded at 1:00 p.M.,at what tim
madam [21]

Answer:

1.30 p.M.

Step-by-step explanation:

The factory whistle blowed at 1:00 p.M, and it blows every 30 minutes, so it will blow again at 1:30 p.M.

The clock tower chimed at 1.00 p.M., and it chimes every 15 minutes, so it will chime again at 1:15 p.M, and after that, it will chime again at 1:30 p.M.

So, you will hear them both at the same time at 1:30 p.M.

We can also solve this problem using LCM:

the least commom multiple between 15 and 30 is 30, so we just need to sum 30 to the inicial time (1:00 p.M.), so the time they will "find each other" again is 1.30 p.M.

You deposit $20,000 in an account that pays 7.77% annual interest. Find the balance after 2 years when the interest is compounde
Mademuasel [1]

Answer:

The account balance after 24 months will be $23,092.70

Step-by-step explanation:

Given data

P= $20,000

r= 7.77%= 0.077

t= 2 years

A= ?

n= 24

The compound interest formula is

A= P(1+t)^t

Inserting our values to solve for A we have

A= 20000(1+\frac{0.077}{24} )^2^*^2^4\\\\A= 20000(1+0.003 )^2^*^2^4\\\\A= 20000(1.003 )^2^*^2^4\\\A= 20000(1.003 )^4^8\\\A= 20000*1.15463517818\\\A= 23092.7035636\\\A= 23,092.70

How do you simplify this equation?
faust18 [17]

<u>Answer:</u>

The answer is B --> \frac{x^{2} }{3x^{2} -1}

<u>How I got that:</u>

<u />

These are really easy, you're simply looking for numbers that you can factor down. Like here:

I took:

\frac{4x^{2} }{12x^{2} -4}

and saw that I could factor out 4 from the denominator:

\frac{4x^{2} }{4(3x^{2} -1)}

and then I canceled out the common factor (4 because its on both sides):

\frac{x^{2} }{3x^{2} -1}

And there ya go!
