C cuz if it opens down a is negative and also it’s a parabola so it’s quadratic
Answer:
The probability is 3/12. The third option is correct.
Step-by-step explanation:
The sample space is
Note that this sample space is not equally probable.
The probability of getting a given number followed is the probability of getting an even number from the 6 numbers (3/6) multiplied by the probability of getting a head after getting that even number, that is 1/2, because is equally probable to get heads or tails from one single coin toss (note that we are assuming that the dice was even, thats why there is a single coin toss).
Therefore, the probability of getting an even number and a head is
P( D in {2,4,6} , H = 1) = P(D in {2,4,6}) * P(H=1 | D in {2,4,6}) = 3/6 * 1/2 = 3/12.
Answer: 1/36
Step-by-step explanation:
Calm down, I'm here to help! You might want to watch some videos on how to solve negative powers, but it's simpler than you think.
An exponent expression is formatted as a^b.
If "b", the exponent, is negative, then you can solve expression like this:
1/a^-b
By writing -b, I mean the opposite of b. For example, the opposite of -2 is 2.
Let's use that rule to solve this problem.
1/6^-(-2)
1/6^2
1/6*6
1/36
There you go! It's not too scary now, is it? Let me know if you'd like me to link some resources!
The temperature on Thursday morning would be -13°F.
Since the temperature decreased throughout the night, this is a subtraction problem.
-5 - 8 = - 13
Answer:
A = 3W² + W + 1/8πW²
Step-by-step explanation:
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
A = 3W² + W + 1/8πW²
