11%= 0.11 and 8%= 0.08

0.11 x 67,530=7,428.3
0.08 x 85,740 = 6,859.2
so person A made more than person b

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 2 In x + In(x - 2) = 0

Pani-rosa [81]

Answer:

The value of x is about 2.206.

Step-by-step explanation:

Consider the given equation is

$2\ln x+\ln (x-2)=0$

We need to find the value of x.

Using the properties of logarithm we get

$\ln x^2+\ln (x-2)=0$ $[\because \ln a^b=b\ln a]$

$\ln (x^2(x-2))=0$ $[\because \ln (ab)=\ln a+\ln b]$

$\ln (x^2(x-2))=ln 1$ $[\because \ln 1=0]$

On comparing both sides we get

$x^2(x-2)=1$

$x^3-2x^2=1$

Using graphing calculator, the real solution of the above equation is

$x\approx 2.206$

Therefore, the value of x is about 2.206.

Four scales of measurement are: nominal, ordinal, interval, and ratio.

RideAnS [48]

Answer:

The answer are (a) measurement on ordinary scale can be ranked, but on nominal scale observation cannot be ranked, (b) on the interval scale measurement can be compared in terms of difference of magnitude, but on ordinary scale, observations cannot be compared in terms of magnitude (c) the point of zero is arbitrary and can be found in any where on the measurement of interval scale

Step-by-step explanation:

Explanation

(a) In nominal scale measurement, observations are classified but in ordinal scale measurement observations are ranked

Therefore additional information of comparing ranking in observation when measurement are gotten from ordinary scale as compared to nominal measurement.

(b) In interval scale measurement can be compared by different magnitude because it is ranked, while ordinary scale measurement, observation can be ranked for comparison

For example the grade of student in a school are grouped under the ordinary scale of measurement due to the fact that Grade A is greater than B

Therefore we have extra information of contrasting observations based on magnitude differences when measurement are gotten form interval scale as against ordinary scale

(c) In the interval scale of measurement, observations are compared in terms of magnitude differences. the point of zero is arbitrary and can found anywhere

For example if a person has no salary what this means is that he has rupes of zero (salary)

Then again, the additional information of the zero point of arbitrary is when measurement is gotten from interval scale. what this suggest is that none is in the scale of ratio
