Answer: $ 90305.56
Step-by-step explanation:
To find the future value of the amount, use the compound interest formula as follows:
A = P( 1 + i/m)^mn
Where; A = Future amount after n years;
P = Principal amount or amount deposited which is equal to $50, 000 in this question.
i = interest rate charge which is 6% in this case
m = number of times compounded per year, thus, m = 2 in this case since it is compounded semi-annually.
n = number of years which is 10 years in this case.
Substituting in the equation:
A = 50 000( 1 + 0.06/2) ^ 2(10)
= $ 90305.56
Answer:
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
Step-by-step explanation:
Assume;
Complementary angle 1st = a
Complementary angle 2nd = a - 42.6°
Sum of complementary angles = 90°
So,
a + a - 42.6 = 90
a = 66.3
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
