See the picture attached to better understand the problem

we know that
A quadrilateral is called Cyclic quadrilateral if its all vertices lie on the circle.
The opposite angles of a Cyclic - quadrilateral are supplementary
so
∠A+∠C=180°
and
∠B+∠D=180°

therefore
the answer is
C) The sum measure of ∠B and ∠D equals 180°

ANSWER PLEASE FINAL DUE IN 3 HOURS

Answer:

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD

here, x = 130, mean = 120 and SD = 10

Substituting these values

z-score = (130-120)/10 = 10/10 = 1

So the probability we want to calculate is;

P(z ≥ 1) = 1 - P(z <1)

From standard score table, P(z <1) = 0.15866

P(z ≥ 1) = 1-0.15866 = 0.84134

How can I get -1 with theses answers

LiRa [457]

You can't get negative 1 from any equation shown in this picture. By the way, -5 +(-9) is not negative 4, it is negative 14,because according to PEMDAS( or BODMAS/BIDMAS/BEDMAS ), parenthesis goes first, so it's kinda like
(-9) + -5 instead.
