Answer: 25 pi

Step-by-step explanation: To find the area of a circle, first start with the formula for the area of a circle which is shown here.

Area = \pi r^{2}

Answer:

115.48m^{2}

Step-by-step explanation:

This shape can be split into two distinct shapes

Two halves of a semi circle, and a rectangle in between

Circle:

Putting both halves of the semi circle together will give you a full circle. The diameter of the circle is given (7m).

The area of a circle is A = π r^{2}

The radius, r, is half of the diameter, so 7 / 2 = 3.5m

A = π r^{2}

A = π * 3.5^{2}

A = 38.38m^{2}

Rectangle:

The area of a rectangle is A = h b

The height, h, is known at 7m

The base, b, can be found by removing the length from the dot to the end of the semi circles. This length is the radius of the semi circles, 3.5m

Removing the radius from the total length given

18 - 3.5 - 3.5 = 11m

The base is 11m

A = h b

A = 7 * 11 = 77m^{2}

Total Area = Circle area + Rectangle area

Total Area = 38.38 + 77 = 115.48m^{2}

A meteorologist in denver recorded y = the number of days of rain during a 30-day period. does y have a binomial distribution? i
olga_2 [115]

Solution: Yes, the random variable y will have a binomial distribution. Because there are two possible outcomes 1. number of days of rain and 2. number of days of no rain.

The parameters of binomial distribution are n and p

The parameter n is given as the number of day's under consideration.

\therefore n=30

The parameter p is not given, but it can be estimated by number of days it rained divided by the total number of days under consideration.

\therefore p=\frac{y}{n} =\frac{y}{30}

50 points for the answer!!! Please help
KATRIN_1 [288]
Okay so I did the problem and they tricked us. That minus sign you see next to the x48 is actually a negative sign so you actually are suppose to divide to get 1.3 and I believe that's the answer.

X=1

x2= 1.3
