Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps

The table gives the scores of 6 students from a class of 25 in a competitive exam. the point estimate of the mean score for the
Ymorist [56]

The mean of the scores if 6 students in a competitive exam is 25 marks.

Given scores of 6 students are: 10,30,50,40,20 in a competitive exam.

We have to find out the mean of the mark of 6 students in a competitive exam.

Mean is the sum of all the values in a set of data, such as numbers, measurements, divided by the number of values. It is also known as average.

Mean=∑X/n

∑X=10+30+50+40+20

=150

N=6

Now to calculate the mean we have to divide 150 by number of students which is 6.

Mean=150/6

=25 marks.

Hence the mean of the scores of 6  students is 25 marks.

Question is incomplete as it should include :
