Answer:
10
Step-by-step explanation:
11, 13, 4, 9
In order to find the median we must first arrange the numbers in order (Least to greatest)
4, 9, 11, 13
If there is 2 numbers in the middle: the median is their average
If there is only one number in the middle, that number is the median.
Since there are two numbers (9 and 11) we have to take their average.
(9+11) / 2 = 20 / 2 = 10
The median is 10!
<u>Answer:</u>
19.5 x 29.25 inches
<u>Step-by-step explanation:</u>
We are given that the top of the table, which we are to build in our factory must of the the dimension 50 cm x 75 cm.
Also, out machine is calibrated in inches. So to find the size of the table in the inches, we need to multiply the given dimensions of the table top with the scale (1 cm = 0.39 inches)
50 cm ---> 50 x 0.39 = 19.5 inches
75 cm ---> 78 x 0.39 = 29.25 inches
Therefore, the dimensions of the table in inches are 19.5 x 29.25 inches.
Answer:
2.4 miles
Step-by-step explanation:
This is a simple ratio problem.
Penguins go 4/5 mile in 1/3rd hour. <em>So how many miles will they go in 1 hour? Let that be x:</em>
<em>
</em>
<em />
<em>That is 12/5 miles or 2 2/5 miles</em>
<em>In decimal, that's </em><em>2.4 miles</em>
Given the slope m and a point (a,b) of a line, its equation is given by

In your case, a = -4, b = 7 and m=1/2, so we have
