Hi There!

Full Question:
The box plots show the high temperatures in June and August for Denver in degrees Fahrenheit.
Which can you tell about the mean temperatures for these two months?
There is not enough information to determine the mean temperatures.
The mean temperature for August is higher than June's mean temperature.
The mean temperature for June is equal to the mean temperature for August.
The high interquartile range for August pulls the mean temperature above June's mean temperature.
---------------------------------------------------------
Interquartile Range Formula: Q3 - Q1
Interquartile Range for August: 10
Interquartile Range for June: 8
---------------------------------------------------------
Median = Mean
June: 82
August: 82
---------------------------------------------------------
Answer: The mean temperature for June is equal to the mean temperature for August.

Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
Answer:
The vertex is (-3,1)
Step-by-step explanation:
Here, we want to write the given function in the vertex form
Mathematically, we have this as;
y = a(x-h)^2 + k
where the vertex is (-h,k)
Thus, we have
Let us divide the coefficient of x by 2, square and add to both sides ; prior to this, we will equate y to 0
Thus, we have it that;
0 = x^2 + 6x + 10
x^2 + 6x + 10 + 9 = 9
x^2 + 6x + 9 = 9-10
x^2 + 6x + 9 = -1
(x + 3)^2 = -1
(x + 3)^2 + 1 = 0
So the vertex here as represented by (-h,k) is;
(-3,1)
