16 because 40-12=28 and Samad will be 28 on 16 years. In 16 years his father will be 56 which is double of 28.
Answer:
x^2\ 16 - y^2/9 = 1
step-by-step explanation:
soooo the equation for a hyperbola that is horizontal is x^2/a^2 - y^2/b^2 = 1
a hyperbola should always equal one so dont forget that when writing your equation becuase it is easy to forget.
it helps to graph this so you can see it better
to find a it is the distance from the center to the vertices which is 4 so in the equation you will write 16 becuase it is a^2
then you need to find b. to get b you have to figure out that c is the distance from the center to the foci which is 5 and it is all related to the plythagorm theorum becuase it forms a right triangle. so you do c^2 - a^2 = b^2
you get 9 for b^2 because 25-16=9 and so you put that in the equation
x = 8
Since x = 8, you can plug in/substitute 8 for "x" in the equation:
2.82842
2.83 You answer is the 4th option
x = 9
Plug in 9 for "x" in the equation
4 Your answer is the 1st option
Answer:
0.1306
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of free throws
x = Number of successes required = 6
p = probability of success = 0.60
q = probability of failure = 1 - 0.60 = 0.40
P(X = 6) = ⁷C₆ (0.6)⁶ (0.4)⁷⁻⁶ = 0.1306368 = 0.1306
