We need to know where tge angle is and what type of triangle it is
Answer: The size of sample of 193 is needed.
Step-by-step explanation:
Since we have given that
Margin of error = 6%
At 90% confidence level, z = 1.645
Let p = 0.5
and q = 0.5
( because it is the most conservative estimation).
So, using formula, we get :
Hence, the size of sample of 193 is needed.
9514 1404 393
Answer:
- 10,247.38 from continuous compounding
- 10,228.50 from semiannual compounding
- continuous compounding earns more
Step-by-step explanation:
The formula for the account balance from continuously compounded interest at annual rate r for t years is ...
A = Pe^(rt) . . . . P = principal invested
A = 8820e^(0.05·3) ≈ 10,247.38 . . . continuous compounding
__
The formula for the account balance from interest compounded semiannually at annual rate r for t years is ...
A = P(1 +r/2)^(2t)
A = 8820(1 +.05/2)^(2·3) ≈ 10,228.50 . . . semiannual compounding
Continuous compounding earns more.
19 has two factors: 1, 19
21 has four factors: 1, 3, 7, 21
23 has two factors: 1, 23
And so we need a number that has more than four factors, and is greater than 25.
50 is one number that fits.
Factors of 50: 1, 2, 5, 10, 25, 50
50 has six factors and is greater than 25.
Hope that helped :)
Answer:2
Step-by-step explanation:
Make the numbers whole by multiplying by 15 to both fractions. 4/5 would become 12 and 2/3 would become 10. Subtract 12-10 to get 2.
