Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13
She will make 9 rows because 27 + 27 = 54 and divided by 6 =9
Answer:
P(X = 2) = 0.22.
Step-by-step explanation:
We are given with the following probability distribution below;
X P(X)
1 0.05
2 0.22
3 0.35
4 0.30
5 <u> 0.08 </u>
Total <u> </u><u> 1</u><u> </u>
As the sum of all the probabilities is equal to 1, which means that this is a valid probability distribution.
Now, from the table above P(X = 2) = 0.22.
Hence, the probability that the X is equal to 2 is 0.22 or 22%.
Answer:
5x + 9
Step-by-step explanation:
f(x) = 3x+4
g(x) = 2x + 5
(f+g)(x)
(3x+4) + (2x + 5)
= 5x + 9
