PLEASE HELP WITH STEPS!!!!!!! ANSWER IN SCIENTIFIC NOTATION I WILL GIVE BRIANLIEST
1 answer:
Answer:
C.) 8.68686 ×
D.) 4.1688 ×
Step-by-step explanation:
For C.) you take 8.69 and multiply that by and you'll get 86900000
Then you take 3.14 and multiply that by and you'll get 31400
So then you take 86900000 and 31400 and subtract it...
86900000 - 31400 = 86868600 and you convert 86868600 to scientific Notation.
Which would equal **** 8.68686 × *****
For D.) you take 4.32 and multiply that by and You'll get 4320
then you take 9.65 and multiply that by and you'll get 0.0965
So then you take 4320 and 0.0965 and subtract it...
4320 - 0.0965 = 4319.9035 and you convert 4319.9035 to Scientific Notation.
Which would equal **** 4.1688 × ****

Answer:
Probability that 3 randomly selected persons have same birthday = 0.00820417
Step-by-step explanation:
Probability that 1 person has different birthday = 1
The probability that all three persons have same birthday = 1 - 0.99179583
= 0.00820417
Hence, probability that 3 randomly selected persons have same birthday = 0.00820417
The graph shows a piecewise function, meaning that different functions are shows at different intervals (ranges of x-values).
1) One of the graphs is part of a parabola, meaning the equation is quadratic (has
). That equation must be 
.
2) The other graph is a straight line, meaning it must be a linear equation. That equation must be x + 4.
Looking at the entire graph, you can see that the parabola starts from the left and ends with an open circle at x=2. An open circle means that the graph doesn't have a value at that point, x=2. The linear line starts with a filled point at x=2 and continues to the right. That means we're looking for the choice where:
1)
Since x=2 cannot be a point in the graph, and less than 2 means that the graph includes everything to the left of 2, but not including 2
2)
Since x=2 is a point in the graph, and greater than or equal to 2 means that the graph includes 2 and everything to the right of it
