Answer:
0.0098
Step-by-step explanation:
Probability of being pregnant:100/1000
=1/10.
98% chance:=98/100 ×1/10
=98/1000
Therefore the probability that she really is pregnant is: 0.098
Answer:
No.
Step-by-step explanation:
This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.
To visualize the question, we have:
3.93 x 0.07
This would give us:
0.2751
Kerri would be correct if she was looking for the SUM of the two values.
This would be:
3.93 + 0.07
This would give us:
4
Therefore in trick problems like this ones, it is better to look at what exactly is being asked.
Answer: 15 hours and 37 minutes
Step-by-step explanation: 6 and 1/2 hours is 6 hours and 30 mins
8 and 2/3 hours is 8 hours and 67 mins
So 8 hours + 6 hours is 14 hours
Since 67 minutes is over an hour, we're going to take 60 minutes from 67, leaving u with 7 minutes
Add the 60 minutes to the 14 hours and you get 15 hours.
Take the 7 minutes and add it to the 30 minutes and you get 37 minutes.
All together the answer is 15 hours and 37 minutes
-2^6-(6)^2= -100. Hope this helps have a great day. :)
