Hello!
The mean is the average. To calculate it you add up all the numbers, and divide by how many numbers there were. So for example, if you had 1 and 3, you would add them and divide by two since there were two numbers. We will calculate the mean of this data set below.
(11+21+16+7+10)=65
65/5=13
The mean of the data set is 13.
---------------------------------------------------------------------------------------
Now we need to find the median. To do so we have to first order all of the numbers from least to greatest.
7,10,11,16,21
Now we have to find the number in the middle of the data set.
11 is our median. (Note that when calculating the median with an even number of data points, you will find the mean of the two center numbers)
I hope this helps!
Answer:
Step-by-step explanation:
we have
where
t is the time in seconds
h is the dolphin's height in feet
we know that
When the dolphin return to the water the value of h(t) is equal to zero
so
For h(t)=0
Simplify
see the attached figure to better understand the problem
Answer:robert=120lbs,genesis=100
Step-by-step explanation:take genesis as (x) and since robert is 20 pounds heavier he would be (X+20) so:
x+(x+20) =220lbs
2x+20=220
2x=220-20
2x=200
x=100 which we took as genesis
which leaves robert's weight 100 +20 =120
The possible base and height of a second triangle are 12 and 7, respectively
<h3>How to determine the possible base and height of a second triangle?</h3>
An inverse variation is represented as:
Base * Height = k
Where k is the constant of variation.
In this case, k is the area
So, we have:
Base * Height = Area
For the first triangle, we have:
14 * 6 = Area
Evaluate
Area = 84
Substitute Area = 84 in Base * Height = Area
Base * Height = 84
Express 84 as the product of two numbers
Base * Height = 12 * 7
By comparison;
Base =12 and Height = 7
Hence, the possible base and height of a second triangle are 12 and 7, respectively

N = 5m
n = m + 36
Both equations are equal to n so they equal each other. Solve for m
5m = m + 36
5m - m= m + 36 - m
4m = 36
4m/4=36/4
m = 9
Solve for n by inputting value of m into the given equations.
n = 5m ........................ n = m + 36
n = 5 (9) ....................... n = 9 + 36
n = 45 ........................... n = 45
They match so it's Correct!
m = 9
n = 45
