<span>Multiply the number in the tens place of the bottom number by the number in hundreds place of the top number. Multiply 3 times 7 to equal 21. Add the 1 you carried to equal 22. You don't need to carry the 2 in 22, as there are no more numbers to multiply on this line, so you can just write it down next to the 6.</span>

Multiplying is like adding over and over again. An example would be 2x3. we can show this as 2+2+2, which would be 6. So 2x3=6. I hope that makes sense. :) <span />

Answer:

7 percent

Step-by-step explanation:

We have the following information from the question:

The probability that a student chooses art as an elective is 15 percent: $P(A)=15\%$

The probability that a student chooses art or drama is 20 percent: $P(A\cup D)=20\%$

The probability that a student chooses both art and drama is 2 percent:

$P(A\cap D)=2\%$

Recall that:

$P(A\cup D)=P(A)+P(D)-P(A\cap D)$

We plug in the various probabilities to get:

$20\%=15\%+P(D)-2\%$

$20\%-15\%+2\%=P(D)$

$7\%=P(D)$

$\therefore P(D)=7\%$

Hence the probability that a student chooses drama as an elective is 7 percent

Answer:

Error: $lnx^2=ln 3x$ not $ln\frac{3x}{0}$

Solution:x=0 and 3

Step-by-step explanation:

We have to find the error and correct answer

Given: $2ln x=ln(3x)-[ln9-2ln(3)]$

$lnx^2=ln(3x)-[ln9-ln3^2]$

Using the formula

$alog b=logb^a$

$lnx^2=ln(3x)-[ln9-ln9]$

$lnx^2=ln(3x)-0$

$lnx^2=ln(3x)$

$x^2=3x$

$x^2-3x=0$

$x(x-3)=0$

Therefore, x=0 and x=3

But last step in the given solution

$lnx^2=ln\frac{3x}{0}=\infty$

It is wrong this property is used when

$log m-log n$ then

$log\frac{m}{n}$

Hence, the student wrote $lnx^2=ln\frac{3x}{0}$ instead of $lnx^2=ln3x$ and solution is given by

x=0 and x=3
