There are different formulas for calculating the two types of compound events: Say A and B are two events, then for mutually exclusive events: P(A or B) = P (A) + P(B). For mutually inclusive events, P (A or B) = P(A) + P(B) - P(A and B).
-11b - 4 - (-b + 3) =
-11b - 4 + b - 3 =
-10b - 7 <===
Answer:
<u>The correct answer is D. 114</u>
Step-by-step explanation:
There are 252 students of twelfth grade at Vista View High School.
99 walked to school
11 went by bicycle
28 used the school bus
To find the amount of twelfth graders that rode in a car, we do this calculation:
Amount of twelfth graders that rode in a car = Total of twelfth graders - those who walked - those who went by bicycle - those who used the bus
Replacing with the real values, we have:
Amount of twelfth graders that rode in a car = 252 - 99 - 11 - 28 = 252 - 138 = 114
<u>The correct answer is D. 114</u>
Answer:
No
Step-by-step explanation:
Let's check the first statement with an example. 2 and 3 are positive numbers and their sum (5) is also positive so his first statement is true.
To check the second statement let's look at the negative numbers -1 and -8 for example. Their sum (-9) is also negative so his second statement is true.
To check the third statement let's look at the numbers 9 and -5. One is positive and one is negative, but their sum (4) is positive, so his third statement is false. However if we look at the numbers 4 and -7, their sum is negative so the third statement is partially false.
Answer: $1904.60
Step-by-step explanation:
This is 1500(1+.04/4)^24 where .04/4 is the interest rate for each compounding, or the interest rate /4, for 4 quarters.
The 24 is 4 quarters/year * 6 years
round at the end
=$1904.60
