To determine what percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers. He then collected

Kipish [7]

Answer:

a)There are 14 teachers in Ryan's sample, and 362 teachers in the population.

Step-by-step explanation:

Population:-

The totality of observations with which we are concerned, whether this number be finite or infinite is called population.

Given data population is 376 teachers at a university were female'

Sample:-

A sample is a subset of a Population

sample of given data = 14teachers

The percentage of 376 teachers at a university were female, Ryan randomly selected 14 teachers.

$p = \frac{14}{376} = 0.0372$ = 3.72%

What is the volume of a sphere with a radius of 8 m, rounded to the nearest tenth of a cubic meter?

zlopas [31]

<h3>given:</h3>

radius= 8 m

the volume of the sphere

<h3>solution:</h3>

$v = \frac{4}{3} \pi {r}^{3}$

$v = \frac{4}{3} \times \pi \times {8}^{3}$

$v = 2144.66058 \: {m}^{3}$

$v = 2144.7 \: {m}^{3}$

therefore, the volume of the given sphere is 2144.7 cubic meters.

The 16th term of an AP is three times the 5th term.If the 12th term is 20 more the 7th term.Find the first term and the common d

Vlad1618 [11]

<h3>Answer:</h3>

First term = 6
Common difference= 4

<h3>Solution:</h3>

Let's take the first term as a and the common difference be d

The formula to find the nth term of an arithmetic progression is given by :

an = a + ( n - 1 ) d

According to question, we have :

16th term of an AP is three times the 5th term.

➝ a16 = 3 ( a5 )

➝ a + ( 16 - 1 )d = 3 ( a + ( 5 - 1 )d )

➝ a + 15d = 3 ( a + 4d )

➝ a + 15d = 3a + 12d

➝ 15d - 12d = 3a - a

➝ 3d = 2a

➝ 2a = 3d

➝ a = 3d/2‎ㅤ‎ㅤ‎ㅤ⸻ ( 1 )

And, the 12th term is 20 more the 7th term.

➝ a12 - ( a7 ) = 20

➝ a + ( n - 1 )d -( a + ( n - 1 )d ) = 20

➝ a + ( 12 - 1 )d - + a + ( 7 - 1 )d ) = 20

➝ a + 11d - ( a + 6d ) = 20

➝ a - a + 11d - 6d = 20

➝ 5d = 20

➝ d = 20/ 5

➝ d = 4

Using equation ( 1 )

➝ a = 3d / 2

➝ a = ( 3 × 4 ) / 2

➝ a = 12 / 2

➝ a = 6
