Answer choice D.) is 12/13<br> Please help!!
slava [35]

Look at the picture.

sine=\dfrac{opposite}{hypotenuse}\\\\\sin\angle L=\dfrac{x}{y}

Use the Pythagorean theorem:

x^2=3^2+4^2\\\\x^2=9+16\\\\x^2=25\to x=\sqrt{25}\to x=5

Again use the Pythagorean theorem:

y^2=5^2+12^2\\\\y^2=25+144\\\\y^2=169\to y=\sqrt{169}\to y=13

Calculate sine:

\sin\angle L=\dfrac{5}{13}\to\boxed{B.}

A biologist has determined that a particular osprey has a 70% chance of catching a fish on any given day. Carry out a simulation
Brums [2.3K]
A random variable is used like this:
You close your eyes and point anywhere on the table to choose a number. Since the given random number table is made up of 3 digits, you only get the first two digits. We are also given a 70% of catching a fish, that means that the number you choose should not have a first two digit number greater than 70. If that happens, you go down to the next value. If you reach the bottom, you go up to the next column. This is done 3 times and multiplying the three numbers to get the chance for 1 trials. This is repeated 20 times and the average is obtained.
