Answer: 5.196152423

Step-by-step explanation: Logically considering it's a Rhombus all the sides are equal to each other. So you just need to find the area. In this case you find the area by multiplying the sin of the given angle by the square root of the given side. So, 6²×sin (60)=6²×√3/2=31.17691454. After finding the area you then have to divide the area by it's base to find the height. So, 31.17691454 ÷ 6 = 5.196152423.

I didn't round any of the numbers. Hopefully this is correct.

Sorry about the messy diagrams (never been good at creating them) and how long it took.

A company manufacturing oil seals wants to establish X and R control charts on the process. There are 25 preliminary samples of

alisha [4.7K]

Answer:

A ) i) X control chart : upper limit = 50.475, lower limit = 49.825

ii) R control chart : upper limit = 1.191, lower limit = 0

Step-by-step explanation:

A) Finding the control limits

grand sample mean = 1253.75 / 25 = 50.15

mean range = 14.08 / 25 = 0.5632

Based on X control CHART

The upper control limit ( UCL ) =

grand sample mean + A2* mean range ) = 50.15 + 0.577(0.5632) = 50.475

The lower control limit (LCL)=

grand sample mean - A2 * mean range = 50.15 - 0.577(0.5632) = 49.825

Based on R control charts

The upper limit = D4 * mean range = 2.114 * 0.5632 = 1.191

The lower control limit = D3 * mean range = 0 * 0.5632 = 0

B) estimate the process mean and standard deviation

estimated process mean = 50.15 = grand sample mean

standard deviation = mean range / d2 = 0.5632 / 2.326 = 0.2421

note d2 is obtained from control table

Stacy placed an order for 4 2/5 sacks of brown lentils and 1 sack of green lentils. How much more brown lentils did Stacy order?

OlgaM077 [116]

Stacy ordered $3\frac{2}{5}$ more sacks of brown lentils.

Step-by-step explanation:

Given,

Sack of brown lentils ordered = $4\frac{2}{5}=\frac{22}{5}$

Sack of green lentils ordered = 1

Difference = Sacks of brown lentils - Sacks of green lentils

Difference = $\frac{22}{5}-1$

Difference = $\frac{22-5}{5}$

Difference = $\frac{17}{5} = 3\frac{2}{5}$

Stacy ordered $3\frac{2}{5}$ more sacks of brown lentils.
