Answer:

<h2><u><em>x=±√−1 (NO REAL SOLUTION)</em></u></h2>

Step-by-step explanation:

x² + 1 = 0

1× x²+1=0

x=±√(−1×1)

x=±√−1 (NO REAL SOLUTION)

Use the formula for continuous compounding to compute the balance in the account after 1,5, and 20 years. Also, find the APY for

densk [106]

Answer:

After 1 year: $7,256.59

After 5 years: $8,380.52

After 20 years: $14,381.03

APY = 3.66%

Step-by-step explanation:

If you deposit $7000 with an interest of 3.6%, after 1 year using continuous compounding, you will have

$7000e^{0.036}=7,256.59$

After 5 years you will have

$7000e^{5(0.036)}=8,380.52$

After 20 years

$7000e^{20(0.036)}=14,381.03$

To find the APY for the account, we have to compute the interest earned in one year.

We can do it by cross multiplying or by finding a number x such that

$7000(1+\frac{x}{100})=7,256.59$

Operating on this equation we obtain

x = 0.0366 or 3.66%

If the number of observations for each sample is 150 units, what is the 3-sigma upper control limit of the process

bixtya [17]

Complete Question

Complete Question is attached below

Answer:

$UCL= 0.25$

Step-by-step explanation:

From the question we are told that:

Sample size $n=150$

Sample Variants $s=7$

Sigma control limits $Z = 3$

Therefore

Total number of observations is Given as

$T_o=n*s$

$T_o=150 *7$

$T_0=1050$

Generally

Summation of defectivee

$\sum np=23+34+15+30+25+22+18$

$\sum np= 167$

Generally the equation for P-bar is mathematically given by

$P-bar=\frac{\sum np}{T_o}$

$P-bar=\frac{167}{1050}$

$P-bar=0.16$

Therefore

$Sp=\sqrt{\frac{P-bar(1-P-bar)]}{ n}}$

$Sp=\sqrt{\frac{[0.159(1-0.159)]}{150}}$

$Sp=0.03$

Generally the equation for 3-sigma upper control limit of the process is mathematically given by

$UCL = P-bar + Z*Sp$

$UCL= 0.16 + 3*0.03$

$UCL= 0.25$
