A total of 1,716 selections of the 7 flowers are possible.
Step-by-step explanation:
Step 1:
There are 13 flowers from which Jeanine Baker plans to use 7 of them.
To determine the number of selections that are possible we use combinations.
The formula for combinations is;
.
Step 2:
In the given formula, n is the total number of options and r is the number of options to be selected.
For this question,
and
.
So 
So a total of 1,716 selections are possible.
I think the answer is 5.6

Answer:
9 years old.
Step-by-step explanation:
Since the ages of all of these students are being represented in relation to the middle student's age then we can create formulas for each student and then apply them to the formula for the sum of their ages and solve for the middle child's age (M) like so... (oldest child's age is represented by variable O and youngest child's age is represented by variable Y)
O = M + 6
Y = M - 3
30 = (M+6) + M + (M-3) ... combine like terms
30 = 3M + 3 ... subtract 3 from both sides
27 = 3M ... divide both sides by 3
9 = M
Now we know that the middle child is 9 years old.
Answer:
$1620
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the length of the side )
Here V = 5832 , then
s³ = 5832 ( take cube root of both sides )
s =
= 18 ft
The area of the square floor is then
area = 18² = 324 ft²
cost = 324 × $5 = $1620
