The expression of Volume in cubic meter (8)(6)(6)+(8)(6)(4)
The correct option is (1)
<h3>What is Volume?</h3>Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.
Volume will be,
V= Volume of rectangular pyramid + Volume of cuboid
Volume of rectangular pyramid= * base area* height
= * 6*8*(10-4)
= * 6*8*6
Volume of cuboid= l*b*h
= 4*6*8
So, Volume = * 6*8*6 + 4*6*8
= (8)(6)(6)+(8)(6)(4)
So, The expression of Volume in cubic meter (8)(6)(6)+(8)(6)(4).

Answer:
And we can find this probability using excel or the normal standard tabe and we got:
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 temperatures of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using excel or the normal standard tabe and we got:
