The Wanting Recognition (WR) Scale provides a quantitative measure of a person's level of need for approval and sensitivity to s

levacccp [35]

Answer:

<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>

<em>(37.4544, 40.5456)</em>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the sample size 'n' = 100

Given that the mean of the sample(x⁻) = 39

Given a standard deviation of the sample (σ) = 6

Level of significance = 0.01 or 99%

<u><em>Step(ii):-</em></u>

<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>

<em></em> $(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } ,x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} })$ <em></em>

<em></em> $(39 -2.576 \frac{6}{\sqrt{100} } ,39 + 2.576 \frac{6}{\sqrt{100} })$ <em></em>

<em>(39 - 1.5456 , 39+1.5456)</em>

<em>(37.4544, 40.5456)</em>

<u><em>Final answer:-</em></u>

<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>

<em>(37.4544, 40.5456)</em>

If the 5th term of a geometric progression is 162 and the 8th term is 4374, find the (i) 1st three terms of the sequence; (ii) s

Alona [7]

Answer:

see explanation

Step-by-step explanation:

The nth term of a geometric progression is

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Given a₅ = 162 and a₈ = 4374 , then

a₁ $r^{4}$ = 162 → (1)

a₁ $r^{7}$ = 4374 → (2)

Divide (2) by (1)

$\frac{a_{1}r^{7} }{a_{1}r^{4} }$ = $\frac{4374}{162}$

r³ = 27

r = $\sqrt[3]{27}$ = 3

Substitute r = 3 into (1) and solve for a₁

a₁ $(3)^{4}$ = 162

81a₁ = 162

a₁ = $\frac{162}{81}$ = 2

Then

a₂ = a₁ × 3 = 2 × 3 = 6

a₃ = a₂ × 3 = 6 × 3 = 18

The first 3 terms are 2, 6, 18

(ii)

The sum to n terms of a geometric progression is

$S_{n}$ = $\frac{a_{1}(r^{n}-1) }{r-1}$ , then

$S_{10}$ = $\frac{2(3^{10}-1) }{3-1}$

= $\frac{2(59049-1)}{2}$

= 59049 - 1

= 59048
