Answer:

Step-by-step explanation:

Alright, lets get started.

The given angle is 85°.

Lets convert this angle into radian first.

For this we have to multiply this with \frac{\pi }{180}

So the angle in radian is = 85*\frac{\pi}{180}=1.4835

The formula of area is = \frac{1}{2}angle*r^2

Area = \frac{1}{2}*1.4835*5^2

Area = 18.5 square meter   :   Answer

Hope it will help :)

In an inductive generalization, in order to achieve an error margin of plus or minus 3 percentage points at a confidence level o
ANTONII [103]
Let n =  required random sample size.

Assume that the population standard deviation is known as σ.
Let m =  sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.

Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²

This means that the sample size is about 128 times the population variance.

Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.

Place each of the digits 1, 3, 5, and 6 in the blanks provided to create an expression whose value is 1/10
kompoz [17]

Answer:

\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}

Step-by-step explanation:

From the picture attached,

Multiplication of two fractions gives the result as \frac{1}{10}.

This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.

Therefore, from the given numbers,

5 × 6 = 30

Rest two numbers be placed as the numerator of the fractions.

\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}

         =\frac{1}{10}

Therefore, \frac{1}{5}\times \frac{3}{6}=\frac{1}{10} will be the answer.
