It is 4 because 3 times 4 equals 12
It's 12/35 because tangent is opposite over adjacent, so 12 is opposite of angle M and 35 is adjacent of angle M
If you want to remember cosine, sine, and tangent just remember
SOH CAH TOA
Step-by-step explanation:
A
The probability of wining is 1/4 so it's 25%. so if you win you either win one of 2 object, so we have to divide the chance of wining by the number of object, so (25%)/2
A it's ,12.5% chance of wining the mug
B yes, it will change if she pics the mug first, it will be 25% because it's guaranteed that she will get the mug if she wins
D over dx (x sin^2(x)) = sin(x) (sin(x) + 2 x cos(x))
$16x.15=$2.40
16+2.4=18.40 the answer is $18.40
Hopefully this is helpful.
