Step-by-step explanation:

Given

$P(3) = 50 \%$

$n =42$

Required

The least number of times to land on 3

This is calculated using:

$Least = n * P(3)$

$Least = 42 * 50\%$

$Least = 21$

If the area of a square is 36 inches what is the length of one side?

Pavel [41]

To find the length of a square given the area, we just need to take the square root of the area given. The sqrt of 36 is 6, so each side is 6 inches. :)

Answer:

y=9x+1.6

Step-by-step explanation:

y-10.6=9(x-1)

y-10.6=9x-9

bring the 10.6 over by adding it to both sides

y= 9x + 1.6

An arithmetic sequence has this recursive formula: (a^1 =8, a^n= a^n-1 -6

eduard

Answer:

$a_n = 8 + (n - 1) (-6)$

Step-by-step explanation:

Given

$a_1 = 8$

Recursive: $a_{n} = a_{n-1} - 6$

Required

Determine the formula

Substitute 2 for n to determine $a_2$

$a_{2} = a_{2-1} - 6$

$a_{2} = a_{1} - 6$

Substitute $a_1 = 8$

$a_2 = 8 - 6$

$a_2 = 2$

Next is to determine the common difference, d;

$d = a_2 - a_1$

$d = 2 - 8$

$d = -6$

The nth term of an arithmetic sequence is calculated as

$a_n = a_1 + (n - 1)d$

Substitute $a_1 = 8$ and $d = -6$

$a_n = a_1 + (n - 1)d$

$a_n = 8 + (n - 1) (-6)$

Hence, the nth term of the sequence can be calculated using $a_n = 8 + (n - 1) (-6)$
