sine's rule

sine α = hypotenuse : opposite

opposite = height of the tree (h)

sin 60° = h : 40

h = 40 sin 60 =34.64 = 35 ft

As part of an insurance company’s training program, participants learn how to conduct an analysis of clients’ insurability. The

hammer [34]

Answer:

1) cpk < 1.33, therefore it is not capable

b) cpk = 1.33, therefore it is capable

c) cpk < 1.33, therefore it is not capable

2) Cpk can never be greater than the Cp, but can be equal to it

Step-by-step explanation:

Upper limit (USL) = 47 minutes and Lower limit (LSL) = 30 minutes

a) mean (μ) = 37 minutes, standard deviation (σ) = 3 minutes

$cpk=min(\frac{USL-\mu}{3\sigma}, \frac{\mu - LSL}{3\sigma})=min(\frac{47-37}{3*3},\frac{37-30}{3*3} )=min(1.11,0.78)=0.78$

$cp=(\frac{USL-LSL}{6\sigma})=\frac{47-30}{6*3}=0.94$

cpk < 1.33, therefore it is not capable

b) mean (μ) = 38 minutes, standard deviation (σ) = 2 minutes

$cpk=min(\frac{USL-\mu}{3\sigma}, \frac{\mu - LSL}{3\sigma})=min(\frac{47-38}{3*2},\frac{38-30}{3*2} )=min(1.5,1.33)=1.33$

$cp=(\frac{USL-LSL}{6\sigma})=\frac{47-30}{6*2}=1.42$

cpk = 1.33, therefore it is capable

c) a) mean (μ) = 38.5 minutes, standard deviation (σ) = 2.9 minutes

$cpk=min(\frac{USL-\mu}{3\sigma}, \frac{\mu - LSL}{3\sigma})=min(\frac{47-38.5}{3*2.9},\frac{38.5-30}{3*2.9} )=min(0.98,0.98)=0.98$

$cp=(\frac{USL-LSL}{6\sigma})=\frac{47-30}{6*2.9}=0.98$

cpk < 1.33, therefore it is not capable

2) Cpk can never be greater than the Cp, but can be equal to it

The population, P, of a small island was 6380, correct to the nearest 10. Complete the statement about the limits of P. ……………………

Lady bird [3.3K]

Answer:

6375 ≤ P < 6385

Step-by-step explanation:

When rounding to the nearest 10, the unit value is either rounded to 1 and added to the tens value (if value is greater than or equal to 5) or rounded to 0 (if less Than 5)

Hence, the lower limit of a number p which gives 6380 when rounded to the nearest ten would be 6375 ;

The upper limit of the number p in other to give 6380 when rounded to the nearest 10 will be 6384 (< 6385)
