How many questions today?

Answer 6

*Theres a line over all these A's, I couldn"t type it...so i used (/)
Which is NOT true for any event A?

P(A/)+P(A)=1
P(A)+1-P(A)
P(A/)=1-P(A)
P(A/)+1=P(A)

Answer 7

you messed up the second option.

Answer 8

YES! how did you know!!!!!!
P(A)=1-P(A/)

It's good now

Answer 9

P(A/)+1=P(A)
is not true for any event A. (Fourth ONE in that)

Answer 14

A coin is flipped 3 times and the number of times heads appears is recorded. How many different outcomes can occur?

4
1
8
2
We are done with yesterdays test...I'll tell you how we did after this one
then we'll continue, but this time 15 questions instead of 30....THANK YOU, IF ONLY YOU KNEW HOW MUCH I APPRECIATE YOUR HELP>>>

Answer 15

any thing mentioned about no event is repeated?

Answer 16

no.

Answer 17

I think it is heads and tales recorded, in that problem.

Answer 18

For three tosses of the coin all the possible outcomes are:
.
H-H-H
T-H-H
H-T-H
H-H-T
T-H-T
T-T-H
H-T-T
T-T-T

hence, according to your problem, the answer should be 7 as TTT should not come into consideration. So there might be an error in the question i'm guessing. Mark 8 for now.

Answer 19

next problem ?

Answer 20

Hurry up !

Answer 21

For the function given, state the middle line: ƒ(t) = 3 cos(π t − 1).

Answer 22

y=0
y=3
y=pai
y=-1

Answer 23

y=0

Answer 24

For the given function, state the amplitude and the minimum output for the function:

f (t)=3 cos[t+pai/6]

Answer 25

amplitude is 3

Answer 26

...and the minimum?

Answer 27

you type next question and post it. I will tell u minimum in the mean time.

Answer 28

For the function given, state the period:
f (t)=6 sin [3t-pai/6]-1

Answer 29

minimum for that previous problem is -3

Answer 30

Find the reference angle given: t = 105°.

75°
15°
45°
85°

Answer 31

period is 2 for the before problem.

Answer 32

Find the reference angle given: t = 105°.

75° is the answer.

Answer 33

2pai/3?

Answer 34

yep 2pi/3

Answer 35

funny how you put pi instead of pai, It shows how dumb I am
Given cscθ = 3, find cos(θ).

Answer 36

given csc theta

Answer 37

csc means cosecent or cos?

Answer 38

cosecant

Answer 39

cos(θ) = \[2\sqrt{2}/3\] in quadrant 1



cos(θ) = \[-2\sqrt{2}/3\] in quadrant 2

Answer 40

well done!
Givencos theta=4/5 , find cot(θ).

Answer 41

Told out there also. its 4/3

Answer 42

Find the value of the trigonometric function sin (t) if sec t=-4/3 and the terminal side of angle t lies in quadrant II.
