Lateral area of triangular prism = (a+b+c)h where a, b and c are the sides of the triangular base, h is the height.
LA= (a+b+c)h=
a=4
b=6
c=?
c=9
h=8
c=√6²+4²=√80 or approximately 9
you should get An Area= (4+6+√80)8
LA= 80+8√80
Greater than 90° but less than 180°.
Answer:
Zero(0)
Step-by-step explanation:
From the given information, we are to determine the probability that both ships are hit given that the pirate shoots first.
There are two scenarios
Since the pirate is to shoot first
- If the pirate misses, the Captain's ship is not hit. Therefore there's no chance of both ships getting hit.
- If the pirate hits, we are told that if his ship has been hit, Captain Daniel will always miss. Therefore there is also no chance of both ships getting hit.
P(both ships to be hit given that pirate shoots first) =0
Answer:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then the we know that the distribution for the sample mean
is given by:
And the standard error is given by:

Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then the we know that the distribution for the sample mean
is given by:
And the standard error is given by:

Answer:
y = - x + 4
Step-by-step explanation:
gradient = change in y/change in x
1-6/3--2= -5/5 = -1
y= -x + c
1=-3+c
c=4
equation of line =
y= -x + 4
