The mean is all the numbers added up and then divided by how many x's there are. In this case, it's 27+29+32+32+36+38+38+42+42 = 345, then you divide it by 9 (the number of x's) and you get 38.33
The median you be the number in the center of the string of numbers, 36 in this number line, because there are nine numbers total and 36 has four numbers on each side
27, 29, 32, 32, 36, 38, 38, 42, 42
The range is the biggest number minus the smaller number, 42-27
So the range is 15
Answer:
The smaller angle is 12 and the larger angle is 168
Step-by-step explanation:
Let call the measure of the random angle a. There is a angle that is 14 times of that and supplementary to that the random angle. So that is represented by
Supplementary Angles add up to 180 degrees so let set up an equation
which equal after you combine like with like
Divide 15 by both sides and a=12 and the so smaller angle is 12 and the larger angle is 168
17.2 celcius

Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
Answer:
The solution is:
Part A. which is sqrt(5)^7k/3[/tex]
Part B. k = 18/7
Step-by-step explanation:
Part A.
To solve this part, we're going two use THREE important properties of exponents:
1.
2.
3.
Let's work the numerator using the properties 1, 2 and 3:
Let's work the denominator using the properties 1, 2 and 3:
Now dividing the numerator by the denominator:
Part B
if
Then:
So
Solving for k, we have:
k = 18/7
