Answer:

(A) BD

Step-by-step explanation:

Given: A circle with center O.

To find: Determine the segment which is secant.

Solution: From the given figure, A circle with center O is given.

A secant is a line that intersects the circle in two different points and a tangent is a line that intersects the circle in exactly one point, called the point of tangency.

Thus, in the given figure, OA is the represented as the radius of the circle, EF is represented as the chord of the circle and BC is the tangent by the definition of the tangent.

Thus, BD is represented as secant of the circle because BD is the only segment which is intersecting the circle at two different points.

Malik deposited 1050 in a savings account and it earned 241.50 in simple interest after four years. Find the interest after four
kap26 [50]

Answer:

if it's true simple interest then each year's interest is the same so interest for one year is a quarter of 241.50 which give you the rate but if each year's interest in left in the account the result will be different , it is a really poorly worded question

A survey of an urban university showed that 750 of 1,100 students sampled attended a home football game during the season. Using
sattari [20]

Answer:

b. 0.6592 and 0.7044

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence interval 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

A survey of an urban university showed that 750 of 1,100 students sampled attended a home football game during the season. This means that n = 1100, p = \frac{750}{1100} = 0.6818

90% confidence interval

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6818 - 1.645\sqrt{\frac{0.6818*0.3182}{1100}} = 0.6592

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6818 + 1.645\sqrt{\frac{0.6818*0.3182}{1100}} = 0.7044

So the correct answer is:

b. 0.6592 and 0.7044
