Answer:
the probability is 78.4%
Step-by-step explanation:
there are 3 scenarios
1) gets the price in the 1st box:
the probability is:
P = probability to obtain a price = 4/10= 40%
2) gets the price in the 2nd box
P= probability to fail in the fist box * probability to obtain a price
P= (6/10)*(4/10)=24/100 = 24%
3) gets the price in the 3rd box
P =probability to fail in the first box * probability to fail in the second box*probability to obtain a price =(6/10)*(6/10)*(4/10)=144/1000 = 14,4%
therefore the probability to obtain a price in 3 or less boxes is:
P = 40%+24%+14.4%= 78.4%
Answer:
12 feet
Step-by-step explanation:
30 divided by 5= 6
6 times 3= how far youve already swam(18 feet)
6 times 2= how far you have left(12 feet)
Answer:
It would be D, 62
Step-by-step explanation:
The sample size for the group with the average height is the highest, being at 40 instead of 30, 20, or 10, and therefore has the most accurate average height.
Answer:
Increasing
−5<x<−1
−1<x<1
Decreasing
4<x<7
−8<x<−5
Neither Increasing nor Decreasing
1<x<4
Step-by-step explanation:
For this case we have the following number:
105,159
By definition we have:
thousand place: five-digit number greater than zero.
On the other hand we have as a rule:
When the previous number is greater than or equal to five, then the next number increases by one.
So we have to round off to the nearest ten thousand:
105,159 = 110,000
Answer:
105,159 rounded to the nearest ten thousand is:
105,159 = 110,000
