I’ll give the Brainliest to who answers this question with a reasonable explanation.

Answer:

143.8\:\mathrm{ft^2}

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): \frac{1}{2}\cdot 4.5^2\cdot \pi

Area of trapezoid (average of bases multiplied by height): 16\cdot 7

Thus, the total area of the figure is:

\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}

Step-by-step explanation:

2x-3y=11

3x+3y=9

do addition and you should get

When you calculate the sample size for a proportion, you use an estimate for the population proportion; namely . A conservative
LuckyWell [14K]

Answer: A. 0.50

Step-by-step explanation:

The formula to find the sample size : n=p(1-p)(\dfrac{ z^*}{E})

, where p= Prior estimate of population proportion.

E= Margin of error

z* =Critical z-value.

When , we do not have prior estimate of population proportion , we use p= 0.5 because at p=0.5 it gives the maximum same sample size for the corresponding confidence interval and margin of error.

Therefore , the conservative value for n can be obtained by using p=0.50.

Therefore , the correct answer is A.0.50 .
