Answer:

A -- only

Step-by-step explanation:

A segment bisector intersects a segment at its midpoint.

S is the midpoint of segment PQ, so ST is a segment bisector. (It intersects PQ at its midpoint, S.)

No other midpoints are shown in this drawing.

A perpendicular bisector is perpendicular to the segment it bisects. None are shown in this drawing.

An angle bisector divides an angle into two congruent parts. None are shown in this drawing.

The vertex of a right angle is often marked with a small square. Only point P is the vertex of a right angle in this drawing. (We cannot assume OPQR is a square.)

Answer:

Independent Sampling

Step-by-step explanation:

There are two scenarios for independent sampling .

Testing the mean we get the differences between samples from each population. When both samples are randomly inferences about the populations. can get.

Independent sampling are sample that are selected randomly. Observation does not depend upon value.Many analysis assume that sample are independent.

In this statement 90 dash are divides into two groups Group 1 and Group 2 . Both are standardized that mean both are randomly selected. Means are observed. Observation doesn't depend upon value. So this style of sampling is independent Sample.

A bird leaves its nest and travels 20 miles per hour downwind for x hours. On the return trip, the bird travels 4 miles per hour

natali 33 [55]

We need to calculate a total TIME.
Let the time required to cover distance d at 20 mph be x. d is the ONE WAY distance, not the total distance traveled (which would be 2d).

Remember the formula d=rt: the distance traveled equals the rate times the time. Here, d = rx, and thus x = d/r = d/(20mph)

Let's begin by recognizing that d(going) = d(returning)
Then (20 mph)x = 6 + (16 mph)x

(20 mph)x - (16 mph)x = 6 miles
Then: (4 mph)x = 6 miles
or: x = 1.5 hours

It takes the bird 1.5 hours at 20 mph to cover distance d, which is 30 miles.
Thus, the total time spent flying is 1.5 hours (going) and [1.5 hours + (6 miles)/(16 mph) returning:

1.5 hours + 1.5 hours + 0.375 hours = 3.375 hours total.

The total distance covered is 2d, or 2(30 miles) = 60 miles.

It took me a while and a lot of experimentation to arrive at these results. Please, if my arguments here are not clear, ask questions.

Chelsey wants to join a fitness club. She has a coupon that will give her $12.50 off the monthly rate for the first 6 months. Wi

Ratling [72]

The regular monthly fee without coupon is $ 50

Solution:

Given that, Chelsey wants to join a fitness club

With the coupon, her total cost for the 6 months is $225

Therefore,

With coupon cost for 6 months = 225

She has a coupon that will give her $12.50 off the monthly rate for the first 6 months

Therefore,

For 6 months, coupon gives a off of,

$12.50 \times 6 = 75$

Therefore,

Without coupon cost = 225 + 75 = 300

Thus the regular monthly fee without coupon is:

$\frac{300}{\text{ 6 months }} = 50$

Thus regular monthly fee without coupon is $ 50
