Let A = {1, 2, 8} and B = {2, 7}.
P ( A ∪ B ) = {1, 2, 7, 8}
= 4/10
= 0.4
Answer: 0.4
Answer:
no worries :)
Step-by-step explanation:
Answer:
After 16 rounds the champion of Ping-Pong player can be determined.
Step-by-step explanation:
This is an example of geometric progression,
First term = 65,536
Now we need to find which term is 1 in this GP.
N th term of GP is given by
Substituting
Seventeenth term of this GP is 1.
That is after 16 rounds the champion of Ping-Pong player can be determined.
Y=x+3 (I did this in my head so I'm not sure)
The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA
SOH = Sin is OPPOSITE / HYPOTENUSE
CAH = Cos is ADJACENT / HYPOTENUSE
TOA = Tan is OPPOSITE / ADJACENT
For example if we were to solve question 5
Sin T = 6 root 2 / 19
Cos T = 17 / 19
Tan T = 6 root 2 / 17
Repeat the steps for question 6
For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1
for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so
cos x = 9 / 18
to find x plug: cos^-1 (9/18) in the calculator
