Suppose that Ralph gets a strike when bowling 30% of the time. What is the probability that Ralph does not get a strike on the
next three balls that he bowls? (round to three decimal places)

.3

Step-by-step explanation:

If the probability of Ralph getting a strike is .3, then the probability of him not getting a strike must be .7.  

When finding the probabliity of an event happening multiple times, we multiply the probabilities together.

So,

(7/10) * (7/10) * (7/10) = .343, or .3 rounded.

Note that when multiplying fractions, the numerators get multiplied by each other, and the denominators also get multiplied by each other.

The number of buttons in tin C is 17.
x+4x+x-7= 137
combine like terms
6x-7=137
isolate the variable by adding 7 to both sides
6x=144
divide
x=24
but remember, tin c is x-7 so plug the 24 in, and the answer is 17.
