Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

$\mathbf{n = 10}$ --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

1st guess = 1/10
2nd guess = 1/9
3rd guess = 1/8

So, the required probability is:

$\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}$

$\mathbf{Pr = \frac{1}{720} }$

Hence, the probability that Jake's guesses are correct is 1/720

Jimmie graphs a quadratic function and finds that its zeros are at x=2 and x=3. Which function could Jimmie have graphed?

HACTEHA [7]

The function Jammie graphed is $x^2-5x+6=0$

Step-by-step explanation:

The zeros of quadratic function are at x=2 and x=3

We can write them as:

$x-2=0\,\,and\,\,x-3=0\\or\\(x-2)(x-3)=0$

Multiplying them

$(x-2)(x-3)=0\\x(x-3)-2(x-3)=0\\x^2-3x-2x+6=0\\x^2-5x+6=0$

So, The function Jammie graphed is $x^2-5x+6=0$
