This problem was solved incorrectly. for this problem, circle the mistake in the work/answer, explain what the mistake is, and find the correct answer. use 3.14 for pi and round to the nearest hundredth where necessary

The mistake was that 12² was calculated incorrectly. 12² means '12 squared', which is 12 × 12. Of course, 12 × 12 is 144, but the student worked out 12 × 2, which is 24.

Therefore, to work out the correct answer, the student has to replace 24 with 144 and continue to work out the

A = πr²

A = 3.14 · 12²

A = 3.14 · 144

A = 452.16 yd²

the mistake is that the person multiplied 12 by 2 instead of multiplying 12 by 12, therefore their answer is incorrect.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
