Answer: B
Step-by-step explanation:
Perimeter = 2(length+width)
'CD' = 20×cos(30) = 17.3205
width 'AD' = 20×cos(60) = 10
Perimeter = 2(17.3205+10)
= 2(27.3205)
= 54.641 =54.6
Answer:
The answer is 31
Step-by-step explanation:
221 divided by 6 is 36-5=31
This is correct because if you divide 221 by 6 you get 36 the subtract 5 from 36 and get 31. To check this answer just do 31+5=36 times 6 which is 216 and 221 minus 5 is 216:)
Answer:
$ 6,189.18
Step-by-step explanation:
From the above question, we can deduce that we are meant to find the Principal (Initial Amount ) invested.
The formula for the Principal of a compound interest that is compounded continuously is given as:
P = A / e^rt
Where
P = Principal
A = Totally Amount after time t = $11,300
r = Interest rate = 4.3 % = 0.043
t = 14 years
P = $11,300/ e ^0.043 × 14
P = $ 6,189.18
Hence, Landon needs to invest, $ 6,189.18
The alpha level should always be set to 0.05.
The supplied statement;
How should you select the alpha() level when doing a significance test in practice,
⇒ Use a higher alpha when the consequences of wrongly rejecting the null hypothesis are more severe. Select alpha () = 0.05 in every situation since it is the best option. Use a smaller alpha when the consequences of wrongly rejecting the null hypothesis are more severe.

The shaded area = Circle area - square area
circle area = 314
square area = 100
the the shaded area = 214
