The average number of Saturday night shootings is 5 a night. What’s the chance that there will be a need for exactly 3 shootings

pishuonlain [190]

Answer:

0.14

Step-by-step explanation:

Using the poisson probability relation :

P(x = x) = (λ^x * e^-λ) ÷ x!

From the question ; mean, λ = 5 ; x = 3

Hence,

P(x = 3) = (5^3 * e^-5) ÷ 3!

P(x = 3) = (125 * 0.0067379) / 6

P(x = 3) = 0.8422375 / 6

P(x = 3) = 0.140

I need help with these questions for Quadratic functions

STALIN [3.7K]

Explanation:

1. The general form of a quadratic in standard form* is ...

$f(x)=ax^2+bx+c$

An example is ...

$f(x)=2x^2+3x-5$

The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.

__

2. The general form of a quadratic in vertex form can be written as ...

$f(x)=a(x-h)^2+k$

An example is ...

$f(x)=2(x -3)^2 -5$

The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.

_____

* In the UK, "standard form" is vertex form.

Answer:

$15x-6y=48$

Step-by-step explanation:

So we have the system of equations:

$5x-2y=16\\15x-7y=51$

And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.

We can see that the coefficient of x in the second equation is 15.

So, to match 15, we must multiply the first equation by 3. So:

$3(5x-2y)=3(16)$

Multiply:

$15x-6y=48$

And we're done!
