Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(9x−6)=14

(

)(9x)+(

)(−6)=14(Distribute)

6x+−4=14

6x−4=14

Step 2: Add 4 to both sides.

6x−4+4=14+4

6x=18

Step 3: Divide both sides by 6.

x = 3

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Answer:

1 9/16 in (or 25/16in)

Step-by-step explanation:

4 5/8 = 4 10/16

6 3/16- 4 10/16 = 1 9/16

Material of pipes is irrelevant

Consider the accompanying data on flexural strength (MPa) for concrete beams of a certain type. 7.9 9.7 9.7 8.7 7.0 7.2 11.3 11.

dybincka [34]

Answer:

$\sum X_i = 219.8$

And we can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}= \frac{219.8}{27}= 8.141$

We can calculate the sample variance with this formula:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}= 2.819$

And the sample deviation would be given by:

$s= \sqrt{s^2}=\sqrt{2.819}= 1.679$

Step-by-step explanation:

For this case we have the following data given:

7.9 9.7 9.7 8.7 7.0 7.2 11.3 11.8 7.3 8.1 8.0 11.6 6.8 9.0 6.3 7.0 7.4 8.7 6.8 5.8 7.8 7.7 6.3 7.0 7.7 6.5 10.7

Our variable of interest is given by X="flexural strength (MPa) for concrete beams of a certain type"

And for this case we know that $\sum X_i = 219.8$

And we can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}= \frac{219.8}{27}= 8.141$

We can calculate the sample variance with this formula:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}= 2.819$

And the sample deviation would be given by:

$s= \sqrt{s^2}=\sqrt{2.819}= 1.679$
