Answer:
, option D
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
From a random sample of 50 students, she found that 32 students read at least 1 book last month.
This means that 
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Confidence interval:
So the correct answer is given by option D.
Answer:
If this is the equation you meant to type (3x + 10 = 13x) then the answer is x = 1.
If this is the equation you meant to type (3x - 10 = 13x) then the answer is x = -1.
Answer:
25x + 15800
Step-by-step explanation:
Given
The amount of money in both banks over time represented by the functions;
f ( x ) = 50 x + 6500 and g( x ) = − 25 x + 9300
The total amount of money in the two accounts over time is expressed as;
h(x)= f(x) + g(x)
Substitute;
h(x) = 50 x + 6500 + (− 25 x + 9300)
h(x) = 50x - 25x +6500+9300
h(x) =25x + 15800
Hence the sum of the money in the account over time is 25x + 15800
