Answer:
To calculate annual compound interest, multiply the original amount of your investment or loan, or principal, by the annual interest rate. Add that amount to the principal, then multiply by the interest rate again to get the second year's compounding interest
Step-by-step explanation:
A = P (1+ r/n) ^nt
A = final amount is found if you input 12 months at r
P = initial principal balance = $100 if every month
r = interest rate then interest rate will be 12 month
n = number of times interest applied per time period = 1
t = number of time periods elapsed t = eg 10
Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.
Answer:
2500 ft²
Step-by-step explanation:
The missing area at lower right in the diagram has dimensions...
(4-2 1/4) by (3 - 1 3/4) by (1 1/4)
Then area of that "Missing" space is (1.75)(1.25)= 2.1875 . . . . square inches. The area of the enclosing rectangle is ... (4 in) (3 in) = 12 square inches the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²
_
Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²
Then the actual store area is....
9.8125(256 ft²) = 2512 ft²
Rounded to the nearest 50 ft², this is 2500 ft².
With
a standard deviation of 6 minutes, we will test the hypothesis that σ = 6
against the alternative that σ < 6 if a random sample of the test
times of 20 high school seniors has a standard deviation s = 4.51. use a
0.05 level of significance.
