If 5 x 6 = 30 you can figure out 8 x 6 by adding 6 three times to 30!

30 + 6 = 36

36 + 6 = 42

42 + 6 = 48 <-- the answer is 48!

Answer:

$SD = 8.4932$

Step-by-step explanation:

Given

$Sample\ Size (n) = 289$

$proportion, p= 52\%$

Required

Determine the standard deviation (SD)

The standard deviation of a binomial distribution is calculated as thus:

$SD = \sqrt{np(1-p)}$

Substitute values for n and p

$SD = \sqrt{289 * 52\% * (1-52\%)}$

Convert to decimals

$SD = \sqrt{289 * 0.52 * (1-0.52)}$

$SD = \sqrt{289 * 0.52 * 0.48}$

$SD = \sqrt{72.1344}$

$SD = 8.49319727782$

$SD = 8.4932$ --- <em>approximated</em>

<em>Hence, the calculated standard deviation is approximately 8.4932</em>

How to solve 3x+y=6 and y=-3 using substation method

mafiozo [28]

Answer:

x=3

Step-by-step explanation:

since they give you y this is a very simple problem

simply replace y with -3 and get

3x+(-3)=6

adding a negative number is the same as subtracting a positive number

3x-3=6

add 3 on both sides

3x=9

divide by 3 on both sides

x=3
