When using scientific notation, you only want one number to be in front of the decimal place. If you have to make the number smaller, then the 10^nth power will be positive. If you have to make the number bigger, then 10^nth power will be negative. Example:
0.54 --> 5.4 * 10^-1
35 --> 3.5 * 10^1
The value of n depends on how many spaces the decimal point needs to be moved. For your question, putting 23 in scientific notation would look like this:
23 --> 2.3 * 10^1
Answer:
Step-by-step explanation:
Let X be the no of customers who purchase atleast one item.
X is binomial since there are two outcomes and each customer is independent of the other.
a) Here n =10
Out of 10 customers we expect np = 3 customers to buy at least one item.
b) exactly 3 of the customers would purchase at least one item
=
c) the probability that no more than 3 customers would purchase at least one item
=
I hope this helps you
w +3 < -8.2
w < -16-3
w < -19
Let
Y=the food is yummy
O=overeat
E=exercise
Note:
∪ = or
-> if ... then
(Y∪O)->E
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
