G(t)=t squared - 2; Find g(9)

GaryK [48]

Answer:

Step-by-step explanation:

So we have the function:

$g(t)=t^2-2$

To find g(9), substitute 9 for t. Thus:

$g(9)=9^2-2$

Square:

$g(9)=81-2$

Subtract:

$g(9)=79$

So, our answer is 79.

And we're done!

A recent poll of 700 people who work indoors found that 278 smoke. if the researchers want to be 98% confident of their results

Mice21 [21]

Answer:

We are given:

$\hat{p}=\frac{278}{700}=0.397$

$z_{\frac{0.02}{2}}=2.33$ is the critical value at 0.02 significance level

$E=0.035$ is the margin of error

Therefore, the required sample size is:

$n=\hat{p}(1-\hat{p}) \left(\frac{z_{\frac{0.02}{2}} }{E} \right )^{2}$

$=0.397(1-0.397) \left( \frac{2.33}{0.035} \right)^2$

$=0.239391 \times 4431.755102$

$=1060.922286 \approx 1061$

Therefore, the required sample size n = 1061
