Answer:
divide both sides by 1m
u2-v2=T/1m
add -u2 both sides of the equation
-v2=T/1m -u2
divide both sides by -1
v2= u2 - T/1m
Answer:
see explanation
Step-by-step explanation:
Note the common difference d between consecutive terms
d = 10 - 3 = 17 - 10 = 24 - 17 = 7
This means the sequence is arithmetic with n th term
= a₁ + (n - 1)d
Here a₁ = 3 and d = 7, thus explicit formula is
= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4, thus
= (7 × 18) - 4 = 126 - 4 = 122
A function is when the y value doesn't repeat. the x can repeat infinitely but the y can not to be a function.
The y value is the second number in each set and it doesn't repeat so this IS a function
Answer: a) 683 b) 1067
Step-by-step explanation:
The confidence interval for population proportion is given by :-
a) Given : Significance level :
Critical value :
Margin of error :
Formula to calculate the sample size needed for interval estimate of population proportion :-
Hence, the required sample size would be 683 .
b) If no estimate of the sample proportion is available then the formula to calculate sample size will be :-
Hence, the required sample size would be 1067 .
