Answer:
-1/32
Step-by-step explanation:
To evaluate the expression, substitute x = 2 and y = -4. Then use exponent rules to simplify. Review the rules here:
To evaluate or simplify expressions with exponents, we use exponent rules.
1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2. When we multiply terms with the same bases, we add exponents.
3. When we divide terms with the same bases, we subtract exponents.
4. When we have a base to the exponent of 0, it is 1.
5. A negative exponent creates a fraction.
6. When we raise an exponent to an exponent, we multiply exponents.
7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules to simplify.
The probability for a football player to suffer more than three roken bones will be the the sum of probabilities for 4 broken bones and five broken bones. Looking at the chart provided we can see that the probablity for 4 four broken bones is P(4)=0.10, and for 5 broken bones is P(5)=0.15. Thus the probaility,
P(x>3)=0.10+0.15=0.25.
Answer:
14 pots
Step-by-step explanation:
if teacher pours 1/18 in each pot and there was 7/9 buckets in total, 9 fits into 18 twice so just 7X2 =14 and 9X2=18 so 14 pots were watered
hope this helps
Ok so first you take $64.80 and multiply it by 2.5. You get $162. Now take $162 and subtract $20 from it. You are left with $142.
This situation is represented by the following disjoint inequality:
---------------------------
- The format of a <u>disjoint inequality</u> is:
- Which is read as: x is more than a or at most b.
---------------------------
- In this question, we have number m more than
and at most -10, thus, the disjoint inequality that represents this situation is:
