1 answer:

This is simple math, you know 60 minutes in 1 hour, so do 60 x 41 = 2,460

So it spins 2,460 times per hour.

A die is rolled twice. What is the probability of getting either a multiple of 2 on the first roll or a total of 8 for both roll

Nuetrik [128]

Answer:

Step-by-step explanation:

let A=favorable outcomes for getting multiple of 2

they are 21,22,23,24,25,26,

41,42,43,44,45,46,

61,62,63,64,65,66

P(A)=18/36

let B=total of 8

favorable outcomes are 26,35,44,53,62

P(B)=5/36

P(A∩B)=3/36

P(A OR B)=P(A∪B)=P(A)+P(B)-P(A∩B)=18/36+5/36-3/36=20/36=5/9

Explain whether the following given sets are closed under addition:

Ivan

Answer:

Step-by-step explanation:

a) Yes.

$\forall\ a,b\ \in\ B,\ a+b\in B\ (since\ 0+0=0)$

b) Yes

$W=\{0,1,2,3,..,\}\ (whole\ numbers)\\\forall\ a,b\ \in\ 3W,\ a+b\in 3W\\since:\\a\ \in\ 3W \Longrightarrow\ \exists\ k_1\in W | a=3*k_1\\\\b\ \in\ 3W \Longrightarrow\ \exists\ k_2\in W | b=3*k_2\\\\a+b=3*k_1+3*k_2=3*(k_1+k_2) \in 3W\\$

c) Yes

$\forall n\ \in\ \mathbb{N}: \Longrightarrow\ n+1 \in\ \mathbb{N}\\$

d) No

$3\in V , 3+3=6\notin V\\$

9d-4d-2d+8=-3d help pls

goblinko [34]

Answer:

-8/3 = d OR -2 2/3

Step-by-step explanation:

9d-4d-2d+8=-3d Well first combine all like terms

3d+8=-3d Now isolate the variable by subtracting 4d from both sides

3d(-3d) + 8= -3d (-3d)

8= -3d Divide both sides by -3

-8/3 = d OR -2 2/3
