Answer:
might be X might be 15 my eatimation
Answer:
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:
Step-by-step explanation:
Previous concepts
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
Solution to the problem
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:
The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...
Figure A's Volume= 60
Figure B's Volume= 60
Figure A's Surface Area= 104
Figure B's Surface Area= 248
So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.
Hope that helps. :)
Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
