where are u from bro?
Step-by-step explanation:
I didn't understand your language.
Answer:
The answer is B ---> (5,3)
Step-by-step explanation:
If a line has a slope of zero, then it is just a flat horizontal line. So, a point a that line will be the one with the same y-coordinate. Option B is the only option with a y-coordinate that matches the point in the question.
Have a good day
Answer: sorry, i couldn't graph it
but the equation was done.
7x+25y =12
rearrange it into y=mx+c
it becomes:
25y = -7x + 12
y= -0.28x+12
to find y intercept: x=0
so
y= -0.28*0+12
y=12
to find x intercept, y=0
so
0= -0.28x+12
0.28x = 12
x= 12/0.28
x= 42.857142857142857142857142857143
approximately = 43(whole number) or 42.9(one decimal place) or 42.86( 2 decimal places)
Answer:
They traveling at
in backward direction.
Step-by-step explanation:
Given mass of Ammy 
and velocity is forward at 
Also, mass of Jenny 
Who is travelling in opposite direction 
Let velocity in forward direction is positive and velocity in backward direction is negative.
Also, velocity after crash is 
As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.
Conservation of momentum says momentum before collision should equal to momentum after collision.


So, velocity after collision
≅
is in opposite direction. That is the direction of Jenny.
Answer:
The mean is the better method.
Step-by-step explanation:
The best way to meassure the average height is throught mean. The mean of a sample is the average of that sample's height, and it will be a good estimate for the population's average height.
The mode just finds the most frequent height. Even tough the most frequent height will influence the average height, knowing only what height is the most frequent one doesnt give you enough informtation about how the height is centrally distributed.
As for the median, it is fine to use the median of a sample to estimate the median of the population, but if you use the median to estimate the average height you may have a few issues. For example, if you include babies in your population, the babies will push the average height down a lot and they are far below te median height. This, as a result, will give you a median height of a sample way above the average height of the population, becuase median just weights every person's height the same, while average will weight extreme values more, in the sense that a small proportion of extreme values can push the average far from the median.
