Step-by-step explanation:
oldest= 16
8+12+15+16= 51
51/4 = 12.73 ( average)
-2-(5•-3)= -2-(-15)
= -2+15
=13
Answer:
P (black marble) =3/11
Step-by-step explanation:
We need to find the total number of marbles
4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles
We take away a black marble and throw it away
3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles
The probability of drawing a black marble is
P (black marble) = black/total
=3/11
It exists not linear the curve indicates that the rate of change exists not constant.
<h3>What is a linear Function?</h3>
Linear functions exist as those whose graph exists as a straight line. A linear function exists that can be characterized by the equation
y = mx + c, Where m exists the slope and c exists the intercept on the
y-axis. A linear function contains one independent variable and one dependent variable.
Therefore, the correct answer is option c) No, because the curve indicates that the rate of change is not constant.

If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:
7x - (25x^2 + 12x<span>) = 7x - 25x^2 - 12x = - 25x^2 - 5x
</span>
The correct result would be <span>- 25x^2 - 5x.</span>
