Answer:

1. -3

Step-by-step explanation:

-3*-3=9

9+8=17

Answer:

x = -3

Step-by-step explanation:

-3x + 8 ≥ 14 (subtract 8 from both sides)

-3x ≥ 14 - 8

-3x ≥ 6 (divide both sides by 3)

-x ≥ 2 (multiply both sides by -1, remember to flip the sign when multiplying both sides by negative number)

x ≤ 2 (-1)

x ≤ -2

hence the solution must be a value that is less than -2. From the choices available, the only choice which satisfies this is x = -3

Answer:

The person who has the greatest spread is Jezebal because his range is 22 while Collin's range is 18.

Jezebal's range :

26 - 4 =22

Collin's range:

21 - 3 = 18

The person who has the least IQR is Collin

Jezebal :

4, 5, 8, 10, 11, 14, 20, 20, 26

Since there are nine values 11 is the median so the first quartile is 6.5 and the third quartile is 20. 20 - 6 = 14

Collin : 3, 9, 9, 14, 15, 16, 17, 20, 21

The median is 15, the first quartile is 9 and the third quartile is 18.5. 18.5 - 9 = 9.5

Jezebal has the greatest spread

Collin has the least IQR

For each of the following sequences, • Give a formula for the nth term in the sequence, • Give a recursive definition for the se

Andrew [12]

Answer:

(a) $n^{th} = n$

$f(1) = 1$

$f(n) = f(n-1) + 1$

(b) $n^{th} = 2^{n-1}$

$f(1) = 1$

$f(n) = f(n-1) * 2$

$f(1) = 1$

$f(n) = f(n-1) * n$

Step-by-step explanation:

(a) This is a sequence of consecutive number

$n^{th} = n$

$f(1) = 1$

$f(n) = f(n-1) + 1$

(b) This is a sequence of 2 to the power of n - 1. The next number is twice time of this number

$n^{th} = 2^{n-1}$

$f(1) = 1$

$f(n) = f(n-1) * 2$

$n^{th} = n!$

$f(1) = 1$

$f(n) = f(n-1) * n$
