Answer:

B. $33.7 mm; 54mm^2$

Step-by-step explanation:

To find the perimeter, use the formula:

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

To find area, use the formula:

A = $\frac{1}{2} bh$

A = $\frac{1}{2} (12)(9)$

A = $\frac{1}{2} (108)$

A = 54

An environmentalist wants to find out the fraction of oil tankers that have spills each month. Suppose a sample of 836 tankers i

Alexxandr [17]

Answer:

The 99% confidence interval for the population proportion of oil tankers that have spills each month.

(0.6489 , 0.7311)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 836

Suppose a sample of 836 tankers is drawn. Of these ships, 577 did not have spills.

sample proportion

$p^{-} = \frac{x}{n} = \frac{577}{836} = 0.690$

The 99% confidence interval for the population proportion is determined by

$(p^{-} - Z_{0.01} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.01} \sqrt{\frac{p(1-p)}{n} })$

Step(ii):-

The Z- value = 2.576

$(0.690 - 2.576 \sqrt{\frac{0.690(1-0.690)}{836} } , 0.690 + 2.576 \sqrt{\frac{0.690(1-0.690)}{836} })$

On calculation , we get

(0.690 - 0.0411 , 0.690 + 0.0411)

(0.6489 , 0.7311)

Final answer:-

The 99% confidence interval for the population proportion of oil tankers that have spills each month.

(0.6489 , 0.7311)

Which is the equation of a parabola with focus (-5, 3) and vertex (-5, 6)?

Ulleksa [173]

Answer:

Which is the equation of a parabola with focus (-5, 3) and vertex (-5, 6)?

Focus and Vertex are both on x = –5, so that’s the Axis of Symmetry.

Distance from Vertex to Focus is p = 3-6 = –3.

4p(y-k) = (x-h)^2

4(–3)(y–6) = (x-(-5))^2

–12(y–6) = (x+5)^2

y = (–1/12)(x+5)^2 + 6 <== Answer

Distance from Vertex to Directrix is –p = 3.

Directrix is y = 6+3 = 9.
