180-33=147 it should make a straight line which is 180 degrees and it is already 33 so 147 degrees

Answer:

x = 147 degrees.

Step-by-step explanation:

The 2 horizontal lines are parallel.

The theorem says that 'for a line crossing  2 parallel lines alternate angles are congruent' so the angles marked are both 33 degrees.

These are sometimes called 'Z'  because they are 2 angles inside the letter Z.

Also for a line crossing 2 parallel lines the 2 interior angles are supplementary (add up to 180 degrees) so:

x + 33 = 180

x = 180 - 33

x = 147 degrees.

ANSWER : (9u - 8)2



STEPS:

Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184

Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64

Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)

Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization

The medical director of a company looks at the medical records of all 50 employees and finds that the mean systolic blood pressu
Alekssandra [29.7K]

Considering that the value of 126.07 is valid for the population, it is a parameter.

<h3>What is the difference between a statistic and a parameter?</h3>

  • If the measure is defined only for the sample, it is a statistic.
  • If the measure can be defined for the population, it is a parameter.

In this problem, the mean blood pressure is calculated for all employees, which means that it is valid for the population, hence it is a parameter.
