Answer:
9/10
Step-by-step explanation:
First, the division of two fractions is the multiplication of the first fraction with the inverse of the second fraction. Then, we have:
3/5 ÷ 2/3 = 3/5 × 3/2
Multiplying the numerators and the denominators, then we have only one fraction.
3/5 × 3/2 = 9/10
Solving this division, we assume that the quotient is 0 and the remainder is 9, because the denominator is greater than the numerator.
Answer:
The 90% confidence interval for the true proportion of all consumers who favor the design is (0.52, 0.59).
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 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the true proportion of all consumers who favor the design is (0.52, 0.59).
Answer:
x = 4
Step-by-step explanation:
Since BD is an angle bisector then it divides the opposite side into segments that are proportional to the other 2 sides, that is
= 
, substitute values
= 
( cross- multiply )
3x = 12 ( divide both sides by 3 )
x = 4
