Answer:
b. Must be between 1.3 and 2.2
Step-by-step explanation:
The formula for calculating median is :
Since in our data n is even so we use the formula for calculating median
=
First arranging data in ascending order we get :
1.2, 1.3, 1.9, 2.2, 2.4 and since we know nothing about our sixth value x so we assume that it may take any position in our data.
Now there may be cases for which position is x on ;
= 1.6
= = 2.05 .
So from all these observations we conclude that without knowing what x median of data must be between 1.3 and 2.2 .
The median of a set of bids can be found by arranging them in numerical order and selecting the middle value.
The median is the middle value of a set of data arranged in numerical order. In this case, we have a set of six bids: 2.2, 1.3, 1.9, 1.2, 2.4, and x (blurred number). To find the median, we first need to arrange the bids in numerical order:
Since there are six bids, the middle value will be the fourth number in the ordered list. Therefore, the median is 2.2.

Answer:
See below
Step-by-step explanation:
1. C = 2(3.14) for r
r = C / 3.28
2. A = 1/2 b h for b
b = A2 / h
3. y = Mx + b for x
y - b = Mx
x = (y - b) / M
4. A = 1/2 (a + b) h for h
A = (1/2a + 1/2b)h
A = 1/2ah + 1/2bh
A = (a + b) h / 2
h = 2A / (a + b)
5. V = (3.14) r² h for h
h = V / (3.14 r²)

Answer: See explanation
Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.
