Hi there! :)

4x=-36

Divide both sides by 4 in order to isolate x:

x=-9

Hope this helps you and have a nice day!

From a group of 11 people, you randomly select 4 of them. what is the probability that they are the 4 oldest people in the group

Andre45 [30]

Answer:

<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>

Step-by-step explanation:

In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group

P(O)= <em>favorable number of outcomes / total number of outcomes </em>

= 11! / (11-4)! 4!

= 7! *4! / 11!

=1/ 130

<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>

Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33

Zina [86]

Answer:

The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

Given

$y =-3x^2 + 12x - 33$

Required

The true statement about the extreme value

First, write out the leading coefficient

$Leading = -3$

$-3 < 0$ means that the function would be a downward parabola;

Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.

The maximum value is:

$x = -\frac{b}{2a}$

Where:

$a= -3; b =12; c =-33$

So, we have:

$x = -\frac{12}{2 * -3}$

$x = -\frac{12}{-6}$

$x =2$

Substitute $x =2$ in $y =-3x^2 + 12x - 33$

$y = -3*2^2 + 12 * 2 - 33$

$y = -21$

<em>Hence, the maximum is -21.</em>
