Answer:
The coordinates of point k are (-2.8,-3)
Step-by-step explanation:
we shall use the internal division formula to find the coordinates of point k
Mathematically, the formula is as follows;
Let’s call the coordinates of point k (x,y)
(x , y) = mx2 + nx1/(m + n) , my2 + ny1/(m + n)
From the question;
m = 1 , n = 4
x1 = 4, x2= -2
y1 = -7 , y2 = 13
Substituting these values in the equation, we have the following;
1(-2) + 4(4)/(1 + 4) , 1(13) + 4(-7)/(1+4)
(-2+16)/5, (13 -28)/5
= -14/5, -15/5
= (-2.8, -3)
Answer:30%
Step-by-step explanation:you divide 18 by 100 and then multiply that by 30 and it gives you 5.4 which is close to 5 players. So 30% is the answer

Answer:
The scientist will measure ratio data
Step-by-step explanation:
In this experiment the scientist will measure different variables such as height of the plants, number of leaves or thickness of the stem among others, to compare the different results in the two environments (the one that has synthetic acid rainwater and that doesn't), so that he can determine the effect of the acid rain on a species of plants.
All the data that he will collect will be numbers for example in the day number 1 he measures the height of both plants and he gets that the plant that is in the environment with synthetic acid rainwater measures 1 cm while the one that is in the non-acidic synthetic rainwater measures 2 cm.
As the answers are numbers you can descard the nominal and the ordinal types of measures, and because the diference between the number matters (you know that 2 is bigger than 1) and also the zero means no growing so it determines the value scale, you can descard the interval type of measure, leaving the ratio measure which is a quantitative (the answer has numbers) type of measure in which you can define the order, the exact value between units and you can define an absolute zero.
