This means that everybody answered the same number of items. This means that every data value is equal to the mean. This outcome permits us to say that the sample standard deviation of a data set is zero if and only if all of its values are same or identical.

whats that point ?  (0,2)

from  that point 2.... run 1 ( to the right and up 3) that will take from x4 to y6

(0,2) (4,6) Two points

Find the value of x. Will mark brainliest.
Arlecino [84]

Answer:

15

Step-by-step explanation:

Because this figure is a parallelogram, the diagonals bisect each other. This means that the diagonals cut each other perfectly in half, meaning that x and 15 have the same value. Hope this helps!

1.4x+3.5y please i need help ;-;
Step2247 [10]
If it’s only 1.4x + 3.5y then that’s the answer because you can’t do anything with them. Since one has an x variable and the other has a y variable you can’t combine them together.
