First, use the table above to start putting the answers into your memory. Then use the Math Trainer - Multiplication to train your memory, it is specially designed to help you memorize the tables. Use it a few times a day for about 5 minutes each, and you will learn your tables.
Step-by-step explanation:
The null hypothesis: The department has determined that there should be 40% A’s given, 40% B’s given and 20% C’s given as final grades for the course
If the p-value for this hypothesis test is = 0.000... and this number is lower than the 0.05 significance level, we reject the null hypothesis and conclude that from the result of our observation that final grades do not match this grading guidelines.
It means the grading guidelines was exceeded in terms of As, was less in terms of Bs and was higher in terms of Cs i e the grading guidelines was not consistent with what was stated in the null.
Answer:
0.0221 feet per minute.
Step-by-step explanation:

If the Base Diameter = Height of the Cone
The radius of the Cone = h/2
Therefore,

Rate of Change of the Volume, 
Since gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. Therefore, the Volume of the cone is increasing at a rate of 10 cubic feet per minute.

We want to determine how fast is the height of the pile is increasing when the pile is 24 feet high.
We have:

When the pile is 24 feet high, the height of the pile is increasing at a rate of 0.0221 feet per minute.
Answer:
the total area is 155 + 23.75 +23.75 = 202.5
Step-by-step explanation:
rectangle = 15.5 times 10 =155
tryangle 1 = 4.75 times 10 divided by 2=23.75
tryangle 2 = 23.75
