One condition for performing a hypothesis test is that the observations are independent. Mark is going to take a sample from a population of 400 students. How many students will Marta have to sample without replacement to treat the observations as independent?

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

the answer is ! ?

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
