Answer:3,000,000 = 3 × 1,000,000 = 3 × 106. Notice that the exponent is the same as the number of zeros following the 3. Three million is a verbal expression, 3,000,000 is a decimal expression, and 3 × 106 is scientific notation.
Step-by-step explanation:
answer is side AB
I'm not 100% sure, just a guess
I hope it helps tho
Answer:
Option C
Step-by-step explanation:
Addition theory of probability is used to determine the probability for union of two or more sets.
P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.
P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)
for 3 sets
This can be extended to any number of sets
So addition theory has nothing to do with independent events both occurring
Option c is the right answer.
Answer:

Step-by-step explanation:
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
Hope this helps!
