The equation for future value F of principal P over t years at r% interest compounded continuously is

F=Pe^(rt) =>
8000 = 4000*e^(0.04*t)
Solve for t:
e^(0.04t)=8000/4000=2
0.04t=log(2)
t=log(2)/0.04=17.33 (years)

A researcher would like to estimate the proportion of all children that have been diagnosed with Autism Spectrum Disorder (ASD)
aliina [53]

Answer:

The researcher should use a sample size of at least 140 children to get a margin of error to be within 2%.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence interval 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

M = z\sqrt{\frac{\pi(1-\pi)}{n}} is the margin of error.

95% confidence interval

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so z = 1.96.

We have that:

M = 0.02, \pi = 0.0147

So

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.02 = 1.96\sqrt{\frac{0.0147*(1-0.0147)}{n}}

0.02\sqrt{n} = 0.2359

\sqrt{n} = 11.79

n = 139.1

The researcher should use a sample size of at least 140 children to get a margin of error to be within 2%.

Which sequences are geometric? Check all that apply.
Zigmanuir [339]

Answer:

–2.7, –9, –30, –100, ...

–1, 2.5, –6.25, 15.625, ...

  8, 0.8, 0.08, 0.008, ...

Explanation:

A geometric sequence is a sequence with the ratio between two consecutive terms constant.  This ratio is called the common ratio.

now check all the sequence one by one.

For sequence –2.7, –9, –30, –100, ...

r = \frac{-9}{-2.7}=  3.333

= \frac{-30}{-9}  = 3.3333

=\frac{-100}{-30} = 3.3333

We see that, all the ratios are same.

So this is geometric sequence.

For sequence   –1, 2.5, –6.25, 15.625, ...

r = \frac{2.5}{-1}  =  \frac{-6.25}{2.5}  = \frac{15.625}{-6.25}  = 2.5

This is also geometric sequence.

For sequence  9.1, 9.2, 9.3, 9.4, ...

In this sequence, common ratio  is not same.

So, it is not a geometric sequence.

For sequence    8, 0.8, 0.08, 0.008, ...

Common ratio is same so, it is geometric sequence.

For sequence   4, –4, –12, –20, ...

Common ratio is not same. So, it is not geometric sequence .
