The confidence interval for a <span>(1−α)%</span> confidence level is given by
<span>
(<span>θ0</span>−<span>Z<span>α/2 </span></span><span>σ/√n</span>, <span>θ0</span>+<span>Z<span>α/2 </span></span><span>σ/√n</span>)
</span><span>θ0</span> is the measured statistic, <span>Z<span>α/2</span></span> is the cutoff/critical value, and <span>σ/<span>√n</span></span> is the standard error. σ is the population standard deviation (if known) or can be estimated by a sample standard deviation. n is the sample size.
The cutoff value depends on the test you wish to use, and <span>θ0</span><span> depends on the statistic you wish to estimate.</span>
Answer:
(2)
Step-by-step explanation:
-3,2
-1,-1

slope is -1.5
Your answer is 3x^(2)+3x+6
Hope this helped!
3: terms/ 12, 8r, -3, s, -5, 15t coefficients/ 8r, 1s, 15t
<em><u>Yo</u></em><em>ur answer would be rounded about </em><u><em>140</em></u> because first rectangle =108divided by 9 = 12 which was the the perimeter of the rectangle plus the 90 degree right triangle which was about 36 so there.
