Answer:
Statements A and B are both true.
<h3>
Answer: 120</h3>
===================================================
Explanation:
There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.
5*4*3*2*1 = 120
This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120
Answer:
36
Step-by-step explanation:
The way to read this question would go: What is 72% of 50 because that will get you the number of correct solutions. When reading a statement like that, the word "of" means to multiply. However, before we multiply those two values we have to convert the value "72" into percent form. To do that you just divide it by 100 to get 0.72. Then following the statement, you would do 0.72*50 to get your final value of 36 correct questions
You can repeat 8 till you get to 48 and count how many 8's you needed to get there.
This is one of the many strategys but there are better ones.
