Population parameters are difficult to calculate due to

Mathematics
1 answer:
lilavasa [31]3 years ago
5 0

Answer:

1

option d

2

option a

Step-by-step explanation:

1)

The population is difficult to cover because it involves a lot of cost on procedure. Further, whole population is difficult to cover and it is infeasible to collect data on entire population. For example we want to check the quality of rice in production unit, we could n't test all grains of rice to check the quality rather than we take a portion of rice grains for quality check. Here, if the whole lot of a rice grains are taken then first drawback would be that it will be costly and second it is infeasible to collect data for whole lot of a rice grains.

2)

Teacher's union is planning to calculate the average salary for only high school teachers in a country and salaries for other teachers are not considered. So, from teachers population a sample of high school teacher in a country is selected. Thus, the calculated average will be sample statistic.

Answer:

  • clockwise
  • 90°
  • origin

Step-by-step explanation:

The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

__

∆ABC is transformed by a <u> clockwise </u> rotation <u> 90 </u> degrees with a center at the <u> origin </u>.

Use a reference angle to write sec255∘ in terms of the secant of a positive acute angle. Do not include the degree symbol in you
jarptica [38.1K]

Answer: sec (75) or csc (15)

Step-by-step explanation:

255 is in the 3rd quadrant where the secant is. Here, the tangent and cotangent is positive.

Reference angle for 255 is,

255 - 180 = 75 degrees.

Therefore, sec (255) = sec (75)

= csc (90 - 75) = csc (15)
