Answer: 3/28

Step by Step Explanation:
To solve this equation, we do NOT need the same denominator.
And since both fractions are negative, we know the answer is going to be positive.
So we just multiply normally.

-1/4 • -3/7

We cannot cross cancel anything, so we just multiply across.

-1 • -3 = 3
-4 • -7 = 28

So our answer is 3/28.

Hope this helps! :3

(-1/4) x (-3/7)

= (-1 x -3)/4 x 7

= 3/28

3/28 is the answer.

Hope it helps:)

If 80% of scheduled flights actually take place and cancellations are independent events, what is the probability that 3 separat
Mekhanik [1.2K]

 

We are given that 80% of scheduled flights really take place, therefore this means that:

Probability of flying = 80% = 0.80

 

Now in statistics class, we know that the probability of two or more independent events to occur is simply equivalent to the product of their probabilities, or mathematically written as: (P = Probability)

total P = P1 * P2 * P3 *...

 

In this case, since we are to find for the probability that 3 independent flights will occur, therefore the total probability assuming equal probabilities to fly is:

total probability = 0.80 * 0.80* 0.80

total probability = 0.512

or

total probability = 51.20%

 

This means that there is only a 51.20% chance for 3 flights to occur.

Simplify sin(tan^(-1)x)
AnnZ [28]
Sin (tan^(-1)X)
Sin (1/tan X)
Sin (1/1 / tan X/1)
Tan X = sin X/cos X

Sin (1/1 / sin X/cos X)
Sin (1/1 • cos X/Sin X)
Sin (cos X/sin X )
Cos X.

I believe the correct answer is cos X.

two years of local internet service cost $685 including the installation fee of $85 what is the monthly fee?
zimovet [89]
2 years is the same as 24 months, so the equation would be:
685 = 24x + 85, where x is the monthly fee.
600 = 24x
600/24 = x
x = 25
The monthly fee is $25.
