Answer: 6.5 and 6
Step-by-step explanation:
Answer:
c(x)=(x+3)^2+5
Step-by-step explanation:
To complete the square, the same value needs to be added to both sides.
So, to complete the square x^2+6x+9=(x+3)^2 add 9 to the expression
C(x) =x^2 +6x + 9 + 14
Since 9 was added to the right-hand side also add 9 to the left-hand side
C(x) +9= x^2 +6x + 9 + 14
Using a^2 + 2ab + b^2=(a+b)^2, factor the expression
C(x)+9= (x+3)^2 +14
Move constant to the right-hand side and change its sign
C(x)=(x+3)^2 +14 - 9
Subtract the numbers
C(x)= (x+3)^2 +5
Here is a way you can write an exponent on the phone (x^2) just so you don’t have to explain the 2 is an exponent
i am confused on where the exponent is supposed to be so could you please rewrite it and i will help you solve it!
Answer:
boxes 1, 3, and 4
Step-by-step explanation:
We know that
To determine the intervals you will need to find the lowest and highest numbers
lowest number------> 1
highest number-----> 35
(1 and 35).
A general rule would be 5-7 intervals,
so
I will choose 5.
Here are the intervals with the number of people that were in each:
[1-7] -----------> (9)
[8-14] ---------> (14)
[15-21] --------> (8)
[22-28] ------> (3)
[29-35]-------> (5)
The total of the frequencies was 39 people, and that is how many numbers there are.
