Reil [10]

The population would be set of all Christians of that particular church from where the random samples is collected.

According to the questions,

A study was performed with a random sample 3000 people from one church. In order to find appropriate population for generalizing conclusions

The population would be set of all Christians of that particular church from where the random samples is collected.

  • This is because random samples is collected only from the particular church, so its generalization can only be the possible to large population of that church.

The first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the
Firdavs [7]

Answer:

\boxed{\frac{23}{3} ~in} or \boxed{7,7~in}

.

Step-by-step explanation:

Suppose, the first side is a, the second side is b, and the third side is c. So:

→ a = s - 4

→ b = s

→ c = (s - 4) + 3

→ a + b + c = 15

First step, find the value of s

a + b + c = 15

(s - 4) + s + (s - 4) + 3 = 15

3s - 5 = 15

3s = 15 + 5

3s = 20

s = \frac{20}{3}

So, the third side is

c = (s - 3) + 4

c = s + 1

c = \frac{20}{3} + 1

c = \frac{23}{3}

.

Happy to help :)
