Sabrina can spend at most $5, including tax, to buy 3 cards. She finds 2 cards priced at $1.25 each and 1 card priced at $1.99,

not including tax. Which inequality could be used to determine the amount of money, in dollars, Sabrina can afford to spend on tax (x) when she buys the 3 cards?
2(1.25+1.99)−x≥5

2(1.25+1.99)−x≤5

2(1.25)+1.99+x≤5

2(1.25)+1.99+x≥5

Answer:

2(1.25)+1.99+x≤5

Step-by-step explanation:

Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5

or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: <u>2(1.25)</u> +1.99+x≤5.

Answer:

The LCL of  the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin

LCL of R-chart = 0 * 0.84533 = 0

LCL of R-chart  = 75.128

Step-by-step explanation:

Given data:

number of observations = 15

sample size ( m ) = 6

sum of sample mean = 80.20 ounces

sum of sample range ( R )  = 12.68 ounces

Determine the control limits of an x-bar and R-chart

<em>for an R-chart </em>

LCL of R-chart = D3 * R(bar) ---- ( 1 )

where : m = 6 ,  D3 = 0 , R = 12.68

            R(bar) = 0.84533

back to equation 1

LCL of R-chart = 0 * 0.84533 = 0

<em>for an X-chart </em>

LCL of X-bar) = ( mean ) - (m x R-bar)

                       = 80.20 - ( 6 * 0.84533 )

                       = 75.128

The LCL of  the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
