Answer:
The answer is f(x) = 0.8(2^x)
Step-by-step explanation:
∵ f(x) = 0.8(2^x)
∵ x = -2 ⇒ ∴ f(-2) = 0.8(2^(-2)) = 0.2
∵ x = -1 ⇒ ∴ f(-1) = 0.8(2^(-1)) = 0.4
∵ x = 0 ⇒ ∴ f(0) = 0.8(2^(0)) = 0.8
∵ x = 1 ⇒ ∴ f(1) = 0.8(2^(1)) = 1.6
∵ x = 2 ⇒ ∴ f(2) = 0.8(2^(2)) = 3.2
∴ The answer is f(x) = 0.8(2^x) ⇒ The fourth answer
Answer:
For x-2y=15, it's x= 15 + 2y. For 2x+4y=-18, it's x= -9-2y.
Step-by-step explanation:
Well, without even looking at it, I can say it's a downwards facing parabola, which roots at x = -3 and x = 5. That should do it.
Answer:
n = 5/22
Step-by-step explanation:
That's a final solution.
Answer: a) 1.029, b) (-5.318, -1.282).
Step-by-step explanation:
Since we have given that
and
So, the standard error for comparing the means :
At 95% confidence interval, z = 1.96
So, Confidence interval would be
Hence, a) 1.029, b) (-5.318, -1.282).
