This score has a probability of 0.48, the highest of all four possible scores.
The answer is option 3.
What is probability?
Probability is virtually how possibly something is to happen. every time we're unsure approximately the final results of an occasion, we will speak about the probabilities of positive consequences—how possibly they are. The analysis of activities ruled by means of possibility is called statistics.

Answer:
The instantaneous velocity at is
.
Step-by-step explanation:
We have the position as the function
As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.
so finding the derivate of
∴
The instantaneous velocity at
Therefore, the instantaneous velocity at is

Step-by-step explanation:
There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.

What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Let us assume first number be = x
and, let the second number be = y
then,
multiplication of two number will be :
xy = 64...(1)
addition of two numbers will be -16 that is :
x + y = -16..(2)
we have :
(x+y)² - (x-y)² = 4xy
(x-y)² = (x+y)² - 4xy
(x-y)² = (-16)² - 4 x 64
(x-y)² = 256 - 256
(x-y)² = 0
(x-y) = 0
x = y
Now, from equation (2) we have ":
x + y = -16
x + x = -16
2x = -16
x = y= -8
Therefore, the two numbers multiply to 64 and add up to negative 16 are -8, -8.

-----+ ------- = -16 ⇒ so both of the numbers gonna be -8
-8 × -8 = 64 and -8-8 = -16 :))) i hope this be helpful
