Answer:

Emily wants to find out if the carpool line around her school causes too much traffic on neighborhood roads.The valid sample of the survey is

As the problem is faced by the one of the member of the school , and most of the members would nod this.

As, teacher being the most respected person in that colony, and if they are honest ,

The survey of 25 teachers at the school , will give the best possible result.

But,the better result is given by, 25 members located around that area, because if there is a problem with carpooling, most of the members around that area will be mostly affected by this.And the best solution is to take their  opinion.

So, Option (B)  25 families living near the school , looks best options among the given option provided.

It’s the same distance from the second base to the first base from the second base to third-base the angle formed by the first b
Margaret [11]

Answer:

Distance of home plate to 1st base is equal to home plate to 3rd base

Step-by-step explanation:

Let's first assign each position:

A: home base

B: 1st base

C: 2nd base

D: 3rd base

The information given:

'It’s the same distance from the second base to the first base from the second base to third-base' tells us BC = CD

'the angle formed by the first base second base and Homeplate has the same measure as the angle formed by the base second base home plate' tells us angle(BCA) = angle(DCA)

Check for congruency between triangle ABC and ADC

BC = CD - side congruency (S)

angle(BCA) = angle(DCA) - angle congruency (A)

CA = CA - side congruency (S)

So triangle ABC and ADC fullfill the criteria of congruence property as SAS.

Since both triangle are congruent, another side of the triangles AB and AD must be the same too.

AB = home plate to 1st base

AD = home plate to 3rd base

Therefore we can conclude that the distance of home plate to 1st base is equal to home plate to 3rd base
