a specification for bottle filling has an upper limit of 9.16 ounces and a lower limit of 9.12 ounces. the process is stabilized

ivanzaharov [21]

Answer:

Process Capability ratio / Index = 0.133

Step-by-step explanation:

From the question, we are told:

Upper limit of 9.16 ounces

Lower limit of 9.12 ounces

Process width of 0.05 ounces.

what is the process capability ratio

Process Capability ratio or Index formula

= Cp = (USL - LSL)/(6 × Standard deviation)

Cp = 9.16 - 9.12/6 × 0.05

Cp = 0.04/0.3

Cp = 0.13333333333

Approximately = 0.133

Find the simple interest earned in an account with $300 at 5% annual interest for 7 years.

Fiesta28 [93]

Option A

The simple interest earned is $ 105

Solution:

Given that, $300 at 5% annual interest for 7 years

Therefore,

Principal = $ 300

Rate of interest = 5 %

Number of years = 7

The simple interest is given by formula:

$Simple\ Interest = \frac{p \times n \times r }{100}$

Where,

p is the principal

r is the rate of interest

n is the number of years

Substituting the values in formula,

$Simple\ Interest = \frac{300 \times 7 \times 5 }{100}\\\\Simple\ Interest = 3 \times 7 \times 5\\\\Simple\ Interest = 105$

Thus simple interest earned is $ 105

Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Use the equation 0 = ?16t2 + 38

mario62 [17]

Answer:

t = 2.5 s

Step-by-step explanation:

Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :

$16t^2 + 38.8t + 3 =0$

The above equation is a quadratic equation. The general equation is :

$ax^2+bx+c=0$

Here, a = 16, b = 38.8 and c = 3

The solution of quadratic equation is given by :

$x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\t=\dfrac{-38.8\pm \sqrt{(38.8)^2-4\times (-16)\times 3} }{2\times (-16)}\\\\t=\dfrac{-38.8+\sqrt{(38.8)^{2}-4\times-16\times3}}{-2\times16}, \dfrac{-38.8-\sqrt{(38.8)^{2}-4\times-16\times3}}{-2\times16}\\\\t=-0.075\ s,2.5\ s$

So, at t = 2.5 s the balloon is in air.

The melt in your mouth Chocolate factory sells three times as many mints as it sells almond bars. It sells half as many almond b

HACTEHA [7]

Answer:

sells 2500 candies per month

Step-by-step explanation:

m = mints

a = almond bar

c = caramels

m = 3a

1/2 c = a

m = 3750

3a = m

a = m/3

a = 3750/3

a = 1250

1/2 c = 1250

c = 2 * 1250

c = 2500
