Answer:
P(A or B) = 25%
Step-by-step explanation:
P(A and B) = 30%
P(A) = 40%
P(B) = 15%
Apply given formula:
P(A or B) = P(A) + P(B) - P(AB)
= 40%+15+-30%
= 25%
Answer:
.
Step-by-step explanation:
In expanded form, the number would look like this:
300,000,000 + 10,000,000 + 700,000 + 60,000 + 3,000 + 100 + 40 + 6
When you add the value of all of these digits, it'll get you the number: 310,763,146. Adding all of these values up and getting the number you originally started with is a great method of making sure you got the right answer.
Answer:
73,58,107,49,131
Step-by-step explanation:
m∠1=73°because alternate interior angles
m∠2= 180-49-73=58° because straight lines make 180° angles
m∠3=58+49=107° because alternate interior angles
m∠4 =49° because alternate interior angles
m∠5=180-49=131° because straight lines make 180° angles
