Use a minimum of two sentences to describe the process for writing the ln(x)=2 in exponential form.

attashe74 [19]

Recall that $ln(x)=log_e$

Also recall that $log_a(b)=c$ translates to $a^c=b$

Therefore, $ln(x)=2$ is $log_e(x)=2$ which is $e^2=x$

Daniel guesses that he scored a 95 on his science test. his actual score is 91. what is the percent error in daniel's guess? rou

Brut [27]

Answer:

$\boxed{\boxed{\%\ error=4.4\%}}$

Step-by-step explanation:

Daniel guessed that he would score 95 on his science test, but his actual score was 91.

We know that,

$\%\ error=\dfrac{|\text{Expected value - True value}|}{\text{True value}}\times 100$

Here,

Expected value = 95

True value = 91

Putting the values,

$\%\ error=\dfrac{|\text{95 - 91}|}{\text{91}}\times 100\\\\=\dfrac{|\text{4}|}{\text{91}}\times 100\\\\=\dfrac{4}{\text{91}}\times 100\\\\=4.39\approx 4.4\%$
