Answer:
b. -(x - 7)(x + 10)
Step-by-step explanation:
-x² - 3x + 70
-(x - 7)(x + 10)
Experimental probability is the ratio of number of times the event is occurring to the total number of the trials of the experiment. This implies that it is a ratio of the number of times an event is occurring to the total number of times that the activity has been repeated. Thus we shall use the formula:
Experimental probability=(# of occurrence of the event)/(total # of trials made)
=6/20
=3/10
Answer: 3/10

Hello!</h2>
The answer is:
The piece of paper measures 30.48cm (centimeters)
<h2>
Why?</h2>
We need to convert from inches to centimeters, we can do it using the following convertion factor:

Now, calculating we have:

Hence, we have that the piece of papers measures 30.48cm (centimeters)
Have a nice day!
Combination Formula: (n = distinct objects, r = how many you pick) n!/(r!(n-r)!
So n = 7, r = 5
n! = 7! = 5040
R! = 5! = 120
(n-r) = 2! = 2
120*2=240
5040/240 = 21
21 combinations!
