Answer:

8.4 in

Step-by-step explanation:

Solution:-

- We consider the large right angle triangle namely, " XVW "

- We will recall all the trigonometric ratios that are applicable to all right angled triangles.

- While we are dealing with trigonometric ratios we have the following terms that needs to be correlated with the given specific problem:

            Hypotenuse ( H ): Side opposite to 90 degrees angle

            Base (B): The side adjacent to the available angle ( θ )

            Perpendicular (P): The side opposite to the available angle ( θ )

- We will go ahead and mark our respective sides as follows:

            Angle ( θ ) : 34°

            Hypotenuse ( H ) : XW = 15 in

            Base ( B ) : VW

            Perpendicular ( P ) : VX

- Now recall all the trigonometric ratios studied:

           sin ( θ ) = P / H = VX / XW

           cos ( θ ) = B / H = VW / XW

           tan ( θ ) = P / B = VX / VW

- Now choose the appropriate trigonometric ratio with two values given and one ( VX ) that needs to be determined as follows:

                             sin ( θ ) = P / H = VX / XW

                             sin ( 34° ) = VX / 15

                             VX = 15*sin ( 34° )

                             VX = 8.387 .. ( 8.4 ) in

To estimate the average salary among people in a certain district, a marketing team obtains a simple random sample of 100 people
bogdanovich [222]

Answer:

The interpretation is that we are 90% sure that the true average salary of the district is in this interval.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

The 90% confidence interval for the average salary of the district is  [41500,49750].

This means that we are 90% sure that the true average salary of the district is in this interval.

identify the type of sampling used​ (random, systematic,​ convenience, stratified, or cluster​ sampling) in the situation descri
sertanlavr [38]

Answer: Random sampling

Step-by-step explanation:

  • A random sampling technique is a method of sampling in which each member for the sample is chosen randomly from the population.
  • Systematic sampling :  It is a kind of random sampling in which the members get selected after a fixed interval but a random starting point.
  • Convenience sampling : It is a kind of random sampling in which the members get selected on the basis of researchers convenience.
  • Stratified sampling :  It is a kind of random sampling in which the entire population is divided into a finite number of strata , the researcher select members for sample from each strata.
  • Cluster sampling : It is a kind of random sampling in which the entire population is divided into clusters. Then a random sample of cluster is drawn by researcher.

In the given situation , 784 adults are selected after their telephone numbers were randomly generated by a​ computer.

Therefore , the  type of sampling used​ here is :  random sampling
