Answer:
b squared minus 4ac describes the discriminant which means the amount of solutions that the equation will have.
Answer:
259.15
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
a^2+b^2=c^2
a^2+12^2=20^2
144+a^2=400
a^2=256
a=16
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)

Answer:
No Solution
Step-by-step explanation:
Divide both sides of the equation by -3. Simplify the expression.
-2x-y=5
2x+y=8
Sum the equations vertically to eliminate at least one variable
0=13
The statement is false for any value of x and y, so there's no solution.
