Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

Answer:

The probability of Alex and Jane getting picked is 0.0112 or 1.12

Step-by-step explanation:

Ok, so the probability that Alex is picked is 0.08, then in order for jane to be picked it is another 0.14.

That means that we must figure out what 14% of 0.08 is 0.0112

0.0112 = 1.12%

A 76 foot piece of rope is cut into three pieces where one piece is three times longer than the other two equal pieces. How long

jonny [76]

Let the length of one of the shorter pieces be $\ell$ . Then, we know that two of the pieces are that length, and the third piece is $3 \ell$ . Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for $\ell$ , and then plug that back in to the desired lengths:

$3 \ell + \ell + \ell = 76 ft.$
$5 \ell = 76 ft.$
$\ell = 15.2 ft.$

Shorter pieces: $\ell = \bf 15.2 ft.$
Longer piece: $3 \ell = \bf 45.6 ft.$
