gtnhenbr [62]

Answer:

- 1, 3, 7, 11, 15

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 5 into the rule, that is

a₁ = 4(1) - 5 = 4 - 5 = - 1

a₂ = 4(2) - 5 = 8 - 5 = 3

a₃ = 4(3) - 5 = 12 - 5 = 7

a₄ = 4(4) - 5 = 16 - 5 = 11

a₅ = 4(5) - 5 = 20 - 5 = 15

The first 5 terms are - 1, 3, 7, 11, 15

Romashka-Z-Leto [24]

Answer:

$\= x = 82$

$s = 9.64$

Step-by-step explanation:

From the question we are told that

The data is 87 91 86 82 72 91 60 77 80 79 83 96

Generally the point estimate for the mean is mathematically represented as

$\= x = \frac{\sum x_i }{n}$

=> $\= x = \frac{87 +91 + 86 + \cdots + 96}{12}$

=> $\= x = 82$

Generally the point estimate for the standard deviation is mathematically represented as

$s = \sqrt{\frac{ \sum ( x_i - \= x )^2 }{ n -1 } }$

=> $s = \sqrt{\frac{ ( 87 - 82 )^2 +( 91 - 82 )^2 + \cdots + ( 96 - 82 )^2 }{ 12 -1 } }$

=> $s = 9.64$
