Answer:
126/420
Step-by-step explanation:
you cross multipy 3/10 and x/420 then you get 1260=10x, then you divide by 10 and get 126
Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)
Answer:6
Step-by-step explanation:
What is the mean of the data set?
Data set:
393 ; 399 ; 402 ; 402 ; 407 ; 410 ; 424 ; 425 ; 428
393 + 399 + 402 + 402 + 407 + 410 + 424 + 425 + 428 = 3,690
3,690 / 9 = 410
The mean is 410. It is the average of all numbers.
What is the median of the data set?
Data set:
01 ; 03 ; 14 ; 15 ; 22 ; 35 ; 35 ; 43
There are 8 numbers, we need to get the sum middle 2 and divide it by 2 to get the median.
15 + 22 = 37
37/2 = 18.50
The median is 18.50
