A) you have to do it separably so do 57 divided by 19 first which is 3. Then you can do x^5 divided by x^2. When you are dividing indices you take them away so you are doing 5-2 which is 3 So the answer is 3x^3.
b) idk how to do that sorry
Answer:
Step-by-step explanation:
The Standard Penetration Test (SPT) is a widely used geotechnical test used to estimate soil strength. A SPT hammer drives a split barrel sampler at the bottom of a drive rod and recovers soil samples.
Answer:
a) For this case we see that the cumulative % for 600 is 77.1% so then we will have 0.771 of the values below 600
b) For this case we know that the cumulative percent for 1200 is 98.2% so then the percentage above would be 100-98.2 = 1.8%, so then the proportion above 1200 would be 0.018.
c) For this case we can add the percentages obtained from the previous parts and we got : 77.1% +1.8% = 78.9% and then the proportion that are less than 600 and at least 100 would be 0.789
Step-by-step explanation:
Assuming the cumulative percentages in the figure attached.
What proportion of fire loads are less than 600?
For this case we see that the cumulative % for 600 is 77.1% so then we will have 0.771 of the values below 600
What proportion of fire loads are At least 1200?
For this case we know that the cumulative percent for 1200 is 98.2% so then the percentage above would be 100-98.2 = 1.8%, so then the proportion above 1200 would be 0.018.
What proportion of fire loads are less than 600 at least 120?
For this case we can add the percentages obtained from the previous parts and we got : 77.1% +1.8% = 78.9% and then the proportion that are less than 600 and at least 100 would be 0.789
