A player chooses one of the numbers 1 through 4. After the choice has been made, two regular four-sided (tetrahedral) dice are r

d1i1m1o1n [39]

Answer: $=\frac{-1}{16}$

Step-by-step explanation:

given data:

number to be chosen from = 1,2,3,4.

Solution:

ways the number can show

$2*3*1=6$ ways for your number to appear once.

$1*1=1$ ways for your number to appear twice.

$3*3=9$ ways for your number not to appear at all

$= \frac{6(1) + 1(2) - 9(1)}{16}$

$= \frac{6+2-9}{16}$

$=\frac{-1}{16}$

expected return of the player is $=\frac{-1}{16}$

I need help because I'm solving these questions by the manual, and yet it still says that I am wrong after multiple attempts.

Alexxandr [17]

Answer:

1. QR = HI

2. angle W and angle T

3. WB = UV

Step-by-step explanation:

It could me fill in the part of the proof, since I notice on all of them they only mark one or two of the congruencies on the shapes. I'm not really sure of 3's answer.

Hope this helped somewhat and good luck

Use the discriminant to determine the number of real solutions of the equation. x^2 = -6x - 10

HACTEHA [7]

Answer:

No real solutions.

Step-by-step explanation:

x² + 6x + 10 = 0

a = 1

b = 6

c = 10

D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4

- 4 < 0,

so this equation has no real solutions.
