Answer: 1,2,3 becuase they are all equivalent its just logic when you think abt it
Step-by-step explanation: 4 makes no sense
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4
The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.
So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50
The square root of 50 is 7.1
x= 7.1
2x squared +1 (-)x squared -7 is
a.) x squared +8
