Well, it goes 5 inches per second so after 4 seconds it is 4 times 5 =20 inches under the surface,  add that to 5 feet and you get 6 ft and 8 inches

Find the area of segment CFD given the following information: radius = 8in, area of ΔCBD = 25.9in2, and m∠CBD = 54° Round your a
Llana [10]

Answer:

A. 4.26 in^2

Step-by-step explanation:

Step 1: Find the area of the sector DBC. Here we have to use the formula.

Area of a sector = Central Angle/360 *πr^{2}

The area of the sector DBC = (54/360)*3.14*8^{2}

= 30.16

Step 2: Area of segment CFD = Area of the sector DBC - Area of the ΔCBD

= 30.17 - 25.9

Area of segment CFD = 4.27in^2

Use a normal approximation to find the probability of the indicated number of voters. In this case assume that 150 eligible vote
alexdok [17]
The number of people who voted follows a binomial distribution with probability of having voted p=0.22 and n=150 subjects, which means the approximating normal distribution should have mean np=33 and standard deviation \sqrt{np(1-p)}\approx5.07.

With the continuity correction, you have
