Step-by-step explanation:

The measure of arc AE is

AE = 360° - (100 + 40 + 60)° = 360° - 200° = 160°

∠ BCD = 0.5( m arc AE - m arc BD ), that is

x = 0.5(160 - 40) = 0.5 × 120 = 60

Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all

Mamont248 [21]

Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.

Creating a square model of the two spins :

Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

Sample space = 4² = 16

Combinations without red and yellow :

{BB, BG, GB, GG}
Number of selections without red or yellow = 4

Recall :

Probability = required outcome / Total possible outcomes

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on yellow or red at all is 1/4.

Simplify completely: the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative

True [87]

The answer is a.−4x^2 − 3x + 2

the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is: $\frac{8 x^{3}+6 x^{2} -4x }{-2x}$

$\frac{8 x^{3}+6 x^{2} -4x }{-2x} = -\frac{8 x^{3}+6 x^{2} -4x }{2x}=- \frac{2x*4 x^{2} +2x*3x-2x*2}{2x} =- \frac{2x(4x^{2} +3x-2)}{2x} = \\ \\ =-(4x^{2} +3x-2)=-4x^{2} -3x+2$

Andrew [12]

True

If all sides of a triangle are congruent with those of another triangle, the triangles are congruent. SSS is an abbreviation or mnemonic for side-side-side, telling you what must be congruent in order for this postulate to apply.
