The perimeter is composed of two straight parts and two semicircles. We can use this to break down the problem.

We can find the straight parts easily. They are given in the problem.

straight parts: 82 x 2 = 164 m

The two semicircles make a circle. We just have to find the circumference of a circle with a diameter of 66 cm to get the length of the semicircles.

semicircles: 2(π)(66/2) = 66(3.14) = 207.24 m

answer: 164+207.24 = 371.24 m

DENIUS [597]

Answer:

The distance traveled in 36s is 12440 m

Step-by-step explanation:

Given;

speed of sound, v = 340 m/s

distance traveled by the sound, d(t) = 340t

time of travel, t = 36 s

Distance is given as;

distance = speed x time

d(t) = 340t

d(36) = 340(36)

d = 12440 m

Therefore, the distance traveled in 36s is 12440 m

The range of values for the sample mean that fall within 1 standard error of the mean in a sampling distribution is M39 to M43.
marusya05 [52]

The question is incomplete! The complete question along with answer and explanation is provided below.

Question:

The range of values for the sample mean that fall within 1 standard error of the mean in a sampling distribution is M = 39 to M = 43. What Is the mean of the sampling distribution, and what is the standard error

a) mean = 41, standard error = 2

b) mean = 39 or 43, standard error = 2

c) mean = 41, standard error = 4

e) the mean and standard error are unknowns

Given Information:  

Standard error = 1

Range of values = 39 to 43

Required Information:  

Mean and standard error = ?

Answer:

Mean is 41 and Standard error is 2

Explanation:

We know that the mean and standard error are related as

s = μ + (1)ο

s = μ - (1)ο

43 = μ + (1)ο

39 = μ - (1)ο

option (a) satisfies the above equations

43 = 41 + (1)2

43 = 43

39 = 41 - (1)2

39 = 39

Therefore, the correct option is (a)

Mean is 41 and standard error is 2
