Answer:
11
Step-by-step explanation:
First, order the numbers in the given set from least to greatest:
8 , 9 , 9 , 10 , 12 , 14 , 15 , 15
The median is the number found in the middle of the given set. If the amount of numbers in the set are even (as in this case), then you will find the mean of the two middle numbers.
In this case, the middle numbers are 10 & 12:
Find the mean. The mean is found by adding all the numbers together and dividing by the amount of numbers there is:
(10 + 12)/2 = (22)/2 = 11
11 is your median.

Answer:
x = -9/2
Step-by-step explanation:
Substitute y = -6 in the second equation.
y = 4x + 12
-6 = 4x + 12
Subtract 12 from both sides.
-18 = 4x
Divide by 4.
-9/2 = x
the price is 0.55$ per square foot
Step-by-step explanation:
We can solve the problem by using the rule of three.
In fact, we know that:
1 gallon covers an area of 
While the price per gallon is
$55 per gallon
This means that the price per
is $55, since 1 gallon cover 
Therefore, to find the price per square foot, we can write

WHere x is the price per square foot. Solving for x,

So, the price is 0.55$ per square foot.

Answer:
Probability = 1/8.
Step-by-step explanation:
A number cube has six sides. Each side has a number from 1 to 6. This means that there are 3 even numbers (2, 4, and 6) and 3 odd numbers (1, 3, and 5). Therefore:
P(number cube lands on an even number after roll) = Number of even numbers/Number of total numbers. = 3/6 = 1/2.
Since the cube has to be rolled three times, the probability will be multiplied 3 times (assuming that each roll in independent of each other). Therefore:
P(number cube lands on an even number 3 times after roll) = 1/2 * 1/2 * 1/2 = 1/8.
Therefore, the answer is 1/8!!!
