2 six-sided dice, one green and one red, are released. What is the probability that : The number on the red die is 3

1 answer:

5 0

1/6 bc they all have an equal chance to be all the numbers on the die and their is only 6 numbers on the die so you have 1:6 probability of it being 3

A new hospital tracked the number of births during its first 6 months of operation, as shown in the table. Find a quadratic func

UNO [17]

Let x refers to the Month numbers
And y refers to Number of births

There is 5 steps to find the quadratic function that models the data.

First step ⇒ Plot the data pairs (x, y) in a coordinate plane.
 which are the blue circles in the attached figure

Second step ⇒ Draw the parabola you think best fits the data.
 Which is the red function in the attached figure.

Third step ⇒ Estimate the coordinates of three points on the
 parabola, which are (2, 108), (4, 68), and (6, 75).
 which are the black squares in the attached figure

Fourth step ⇒ Substitute the coordinates of the points into the model 
 y = ax2 + bx + c
 to obtain a system of three linear equations.

 4a + 2 b + c = 108 ---------(1)
 16a + 4 b + c = 68 ---------(2)
36a + 6 b + c = 75 ---------(3)

Fifth step ⇒ Solve the linear system.
 By using the calculator
 a = 5.875 , b = -55.25 , c = 195

So, the quadratic model for the data is ⇒ y = 5.875 x²- 55.25 x + 195
============================================
To predict the number of births for month 8
substitute with x = 8 ⇒ y = 5.875 * 8²- 55.25 * 8 + 195 = 129

What is the difference between a relation

taurus [48]

Answer:

Not all relationships are functions, but all functions are also relationships

Step-by-step explanation:

A relationship is a correspondence between two sets of values.

A relationship assigns values from an output set called range to a set and input called a domain.

On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).

In other words, if an input value $x_1$ is assigned two or more output values $y_1$ , $y_2$ , $y_3$ .. then the relationship is not a function. This means that not all relationships are functions.
