Sketch the standard Normal curve for the test statistic and mark off areas under the curve to show why a value of z z that is significant at the 1 % 1% level in a one‑sided test is always significant at the 5 % 5% level. If z z is significant at the 5 % 5% level, what can you say about its significance at the 1 % 1% level?

answer: was that a question or answer?

step-by-step explanation:

(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

i think the answer is 90 hope this
