Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
Answer:
(2, 8)
Step-by-step explanation:
There are a couple of different ways to do this, but I am going to use substitution since we already have one of those equations solved for y. If y=3x+2, then we can sub 3x+2 in for y in the other equation:
-3x + 2(3x + 2) = 10 and
-3x + 6x + 4 = 10 and
3x + 4 = 10 and
3x = 6 so
x = 2. Now that we know x = 2, we can sub a 2 in for x in either equation to solve for y:
y = 3x + 2 gives us, with the substitution, y = 3(2) + 2 so y = 8. The solution set is (2, 8)
Answer:
a2b
Step-by-step explanation:
a6b3 / a4b2
When dividing exponents, you subtract them.
a6-4
b3-2
Leaving you with a2b
Answer:
$12.68
Step-by-step explanation:
Multiply the price of one pound by the amount of pounds you're buying,
8.45 x 1.5
= 12.675
