Answer:
For this case we need to check the conditions in order to use the normal approximation:
1) 
2) 
Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:
The mean would be given by:
And the deviation is given by:
Step-by-step explanation:
For this case we know the following info:
n =60 represent the sample size
represent the estimated proportion of people that will buy a packet of crackers after tasting
For this case we need to check the conditions in order to use the normal approximation:
1)
2)
Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:
The mean would be given by:
And the deviation is given by:
Answer is A im a full course teacher for this subject
Answer:
The section of a parabola that shows a falling curve with decrease in the y values of the graph is known as the decreasing interval of the quadratic function
Step-by-step explanation:
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
<u>aₙ = 3 + 4ⁿ⁻¹</u>
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
<u>Let's check if the answer is right:</u>
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct
Hope this helps!
