Answer:
24,000 cm^3
Step-by-step explanation:
Volume is LxWxH
20x30x40=24,000cm^3
7/8 miles = 49 / 56 miles so it will take the road crew 49 hours to repave the road.
Step-by-step explanation:
The quadratic formula is honestly the most straightforward way of solving here.
Your other options are completing the square (which is the same thing as the quadratic formula but it's good to know that method if you have to take Integral Calculus at some point) or maybe factoring by grouping if it's appropriate. But the quadratic formula will work for you in all three equations:
1) a=1, b=0, c=8
This reduces pretty quickly into x=8i,-8i due to the negative under the radical. (Actually we didn't even really need the formula here.)
2) a=-9, b=4, c=-10
This reduces into x=(-4+i√(344))/-18, (-4-i√(344))/-18 and doesn't go any further because 344 isn't a perfect square.
3) a=1, b=8, c=17
This reduces to x=(-4+i), (-4-i)
So those are the answers for each.
You only have to count 30° counterclockwise. every point i 30. therefore, OF is the image.
Answer:
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to an unusual situation.
Step-by-step explanation:
A z score measures the standard deviation below and above the mean of data. A formula for calculating z-score is
Essential facts about z-scores:
If data is above average, then the z-score is positive.
If data is below average, then the z-score is negative.
if the point is close to average, then z-score is close to 0
if the point is above 333 or blows 3 then z score is unusual.
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to the unusual situation.
