Answer:
<em>615.44m²</em>
Step-by-step explanation:
The base of the silo is a circle
Rea of the base of the silo = πr²
r is the radius of the silo
Given
radius r = 14m
Area of the base of the silo = π(14)²
Area of the base of the silo = 3.14(196)
Area of the base of the silo = 615.44
<em>Hence the area of the base of the silo is 615.44m²</em>
Answer:
- The amount invested at 5%=$77,000
- The amount invested at 9%=$349,000
Step-by-step explanation:
- Let the amount invested at 5% simple interest =$x
He invested $41,000 more than 4 times the amount at 9%.
- This amount is: $(4x+41000)
Total Annual Interest Earned = $35,260
Therefore, Time=1 year
Simple Interest
Therefore, his total interest
=Interest from Investment 1 + Interest from Investment 2
Therefore:
The amount invested at 5%=$77,000
The amount invested at 9%=$(4*77,000+41000)=$349,000
Equal sets have the exact same elements, so they must have the same number of elements. Therefore, equal sets must also be equivalent. No, not all equivalent sets are also equal sets
To find the answer we simply have to find 12% of 58,800. So to do that, we can multiply it by .12
58,800 • .12 = 7,056
So $7,056 is earned per year
Following are the solution parts for the given question:
For question A:
In the given question, we calculate of the confidence interval for the mean weight of shipped homemade candies that can be calculated as follows:
Using the t table we calculate When of the confidence interval:
So confidence interval for the mean weight of shipped homemade candies is between .
For question B:
Here we need to calculate confidence interval for the true proportion of all college students who own a car which can be calculated as
Using the Z-table we found
therefore the confidence interval for the genuine proportion of college students who possess a car is
So the confidence interval for the genuine proportion of college students who possess a car is between
For question C:
- In question A, We are certain that the weight of supplied homemade candies is between 392.47 grams and 427.53 grams.
-
In question B, We are positive that the true percentage of college students who possess a car is between 0.28 and 0.34.
