Which of the following is an equation of the line through (2,3) and (-1, -12)?

SSSSS [86.1K]

Answer:

C (y=5x-7)

Step-by-step explanation:

First, you find the slope between the 2 points which is 5, then you use one of the points to form an equation.

You then find it's y=5x-7.

In a sample of n = 6 scores, 5 of the scores are each above the mean by one point. Where is the 6th score located relative to th

den301095 [7]

The mean of a dataset is the sum of all data elements divided by the count of the elements.

The location of the 6th score relative to the mean is 5 points below the mean

Let:

$\bar x \to$ Mean

$a \to$ 5 scores

$b \to$ 6th scores

Given that:

$n = 6$

The 5 scores that are 1 above the mean implies that:

$a = \bar x + 1$

The mean of a dataset is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x =\frac{5a + b}{6}$

$\bar x =\frac{5(\bar x + 1) + b}{6}$

Open brackets

$\bar x =\frac{5\bar x + 5 + b}{6}$

Multiply both sides by 6

$6\bar x =5\bar x + 5 + b$

Make b the subject

$b = 6\bar x -5\bar x - 5$

$b = \bar x - 5$

This means that the 6th score is 5 points below the mean

Solve the system of equations. 2x−9y=14 x=−6y+7

ipn [44]

Step-by-step explanation:

$put \: x \: into \: equation \: 1$

$2( - 6y + 7) - 9y = 14$

$- 12y + 14 - 9y = 14$

$- 21y + 14 = 14$

$- 21y = 14 - 14$

$- 21y = 0$

$\frac{ - 21y}{12} = \frac{0}{21}$

$y = 0$

$put \: y = 0 \: into \: equation \: 2$

$x = 6y + 7$

$x = 6(0) + 7$

$x = 0 + 7$

$x = 7$
