$\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\

HELP! After finding area explain the reasoning you used to find the area and I’ll give brainliest!

UkoKoshka [18]

Answer:

The answer is 180 yds squared.

Step-by-step explanation:

Segment the areas. One area has the measurements 5 and 6. Then the other one has measurements 15 and 10. This means you get 150 + 30. The answer is 180 yds squared.

Sample information: 24 out of 1000 people who were surveyed had type 2 diabetes. Use the above sample information and construct

notka56 [123]

Solution :

The sample proportion $(\hat p)=\frac{24}{1000}$

= 0.024

90% confidence interval

The standard deviation = $\sqrt{\frac{\hat p(1-\hat p)}{n}$

= $\sqrt{\frac{0.024(1-0.024)}{1000}$

= 0.00484

z = 1.645 for 90% CI

Upper band = 0.024 + (0.00484 x 1.645 ) = 0.03196

Lower band = 0.024 - (0.00484 x 1.645 ) = 0.01603

Therefore, the 90% CI is (0.016, 0.032)

99% confidence interval

z = 2.576 for 99% CI

Upper band = 0.024 + (2.576 x 0.00484 ) = 0.0365

Lower band = 0.024 - (2.576 x 0.00484 ) = -0.0115

Therefore, the 99% CI is (0.0115, 0.0365)
