He spent 1/4 on Monday, so he had 3/4 left.

He then spent 2/3 of that, to find how much he spent you would multiply 3/4 by 2/3:

3/4 x 2/3 = 6/12 = 1/2

On Tuesday he spent 1/2 of his allowance.

So on Monday and Tuesday he spent 1/4 + 1/2 = 3/4 total.

He would have 1/4 of his allowance left.

The answer is C.

n a large high school, 37% of the teachers believe that five minutes is not enough time for students to change classes. However,
timurjin [86]

The difference (faculty-student) in the sample proportions of those who believe that five minutes is not enough time for students to change classes typically varies about 0.096 from the true difference in proportions. Option D is correct.

<h3>What is the standard deviation?</h3>

It is a measurement of statistical data dispersion. The degree to which the value varies is known as standard deviation.

The standard deviation of the sampling distribution is found as;

\rm \sigma_F-\sigma_s= \sqrt{\frac{0.37 \times (1-0.37)}{28}+\frac{0.89 \times (1-0.89)}{100}  } \\\\  \sigma_F-\sigma_s=0.096

The difference in the sample proportions of those who think five minutes is not enough time for students to switch classrooms generally differs by roughly 0.096 from the actual difference in proportions.

Hence option D is correct.
