Gene's frying pan is 13.5 inches in diameter. What is the circumference of his frying pan?

STALIN [3.7K]

To work out the circumference of a circle, you should use 2πr or πd (r being radius and d being diameter)
So
Circumference = 13.5 x π = 27/2 π = 42.41 inches

Is 6 /1.2 a rational number

olasank [31]

Answer:

yes

Step-by-step explanation:

A rational number can be expressed in the form

$\frac{a}{b}$ ← where a, b are integers

Given

$\frac{6}{1.2}$ ← multiply numerator/ denominator by 10

= $\frac{60}{12}$ = 5 = $\frac{5}{1}$ ← a rational number

How do you interpret the estimated value of coefficient of EDU in the following equation:

tia_tia [17]

Answer:

The correct option is d

Step-by-step explanation:

From the question we are told that

The equation is $ln (SALARY) = 1 + 0.02 ln(EDU)$

generally

$ln (e) = 1$

=> $ln (SALARY) = ln (e) + 0.02 ln(EDU)$

Apply log rules

=> $ln (SALARY) = ln[ e(EDU)^{0.02} ]$

=> $SALARY = e(EDU)^{0.02}$

When EDU is increase by 1% we have that

$\frac{1}{100} * EDU + EDU$

=> $1.01 EDU$

So the new SALARY will now be

$SALARY'' = e(1.01EDU)^{0.02}$

The ratio by which the new SALARY will increase is obtain by dividing the value of new SALARY (SALARY'' ) with that of the former SALARY (SALARY) and this mathematically represented as

$\frac{SALARY'' }{SALARY} = \frac{e*1.01 (EDU)^{0.02}}{e (EDU)^{0.02}}$

=> $\frac{SALARY ''}{SALARY} = 1.0002$

Generally the percentage increase of salary is mathematically evaluated as

$k= (\frac{SALARY''}{SALARY} - 1 ) * 100$

=> $k= (1.0002 - 1 ) * 100$

=> $k= 0.02 \%$
