It's C and D because of the fact that in y=ab^x, a is the initial value. C is correct because we know that Expression A is decaying, and the 'x' is terms of months - not years.

4. For a normal distribution, find the z-score that separates the distribution as follows:

Stolb23 [73]

Let $\Phi(z)$ denote the cumulative distribution function for the standard normal distribution (mean 0, standard deviation 1). Then you're looking for <em>z</em> such that

(a) $\Phi(z) = P(Z\le z) = 0.70$

(b) $\Phi(z) = P(Z\le z) = 0.40$

(c) $\Phi(z) = P(Z\le z) = 0.25$

To get the corresponding <em>z</em>-score for each of 0.70, 0.40, and 0.25, take the inverse CDF of both sides:

(a) $z = \Phi^{-1}(0.70) \approx 0.5244$

(b) $z = \Phi^{-1}(0.40) \approx -0.2533$

(c) $z = \Phi^{-1}(0.25) \approx -0.6745$

The quadratic $10x^2+100x+1000$ can be written in the form $a(x+b)^2+c$, where $a$, $b$, and $c$ are constants. What is $a+b+c$?

alexandr1967 [171]

Answer:

765

Step-by-step explanation:

Hello, please consider the following.

$10x^2+100x+1000=10(x^2+10x+100)\\\\=10((x+5)^2-25+100)\\\\=10(x+5)^2+750$

So, a = 10, b = 5, c = 750 and the sum is 765.

Thank you
