Answer:

D

Step-by-step explanation:

A sin 2.355/2.355  =0.01745240644 cos -2.355/2.355 root square

=180 so untrue not-1

B. sin =0.01745240644 cos = 0 so untrue not 1.

C sin = 0.01745240644 cos = 180 so untrue not 1

D = - 2.355/2.355= 0.01745240644  cos = 0.01745240644 = -1 so true.

As if we divide 1 into -1 = 1

When we divide  0.01745240644 / 0.01745240644 = will also = 1

The answer is -1 as inverse.

You would like to start a club for psychology majors on campus, and you are interested to find out what proportion of psychology
Natalija [7]

From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;

<u><em>- Yes, the sampling method is biased. </em></u>

<u><em>- The likely direction of the bias is because you only asked 5 people which </em></u>

<u><em>is  not a significant percentage of those offering psychology majors and as </em></u>

<u><em>such the 4 out of 5 gotten is likely going to be an over estimation of those </em></u>

<u><em>who are willing to pay to join this club.</em></u>

We are told that;

  • You want to start a club.
  • This club is for psychology majors.
  • You want to find the proportion of those in the psychology majors that will join this club you want to organize.

  • Now, out of all the students offering psychology majors, you only asked 5 of them if they will be interested. Since 4 out of the 5 are interested and you want to use that to form a basis of the proportion of those interested , it would lead to <em>sampling bias</em> since the population is not adequately represented.

Therefore, this would lead to sampling bias and thus the sample is biased.

Please help!!! I need this done today!!
Kryger [21]

Answer:

1) distance travelled = 75mi

time taken = 3 hrs.

speed = distance/time

= 75/3 = 25 mi/hr.

now, if time = 1.6 hrs.

Distance = speed x time

= 25 x 1.6 = 40.0 mi

---------------------------------------------------------------------------------------------

2) earning for 8 hrs. of work = $120.

therefore, rate of earning per hr. = 120/8 = $15/hr.

so, earning in 11 hrs. = 15 x 11 = $165
