Answer:

y=-4\,x-4   which agrees with answer "A" in the list of possible options

Step-by-step explanation:

From the fact that there is a steady rate of increase in the x and in the respective y values (notice that x increases in steps of 1 unit, and at the same time y values increase in steps of "-4" units) the data belongs to the equation of a line.

We can determine that equation using just two pairs of points, like for example (-1, 0) and (0, -4).

We first find the slope using the slope formula for the segment that joints any two points on the plane:

slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-4-0}{0-(-1)}\\slope = -4

we now write the slope-intercept general form of a line with slope "-4", and solve for the intercept by using the point (0,-4) which should be in the line:

y=m\.x+b\\y=-4\,x+b\\-4=-4\,(0)+b\\b=-4

Therefore the equation for this points is:

y=-4\,x-4

URGENT. WILL GIVE BRAINLIEST.
galben [10]

Answer:

A. Miguel has the greatest spread.

B. Considering the middle 50% of the training time, the person with the least spread is Adam.

C. Miguel is inconsistent with the time set for training compared to that of Adam.

Step-by-step explanation:

The spread of a data shows the range of the data.

Using the range to determine the spread of the given data:

A. The range of the two persons can be determined by:

          Range = highest value - lowest value

So that:

Adam's range = 106 - 91

                      = 15

Miguel's range = 105 - 86

                        = 19

Comparing the range of the two, Miguel has the greatest spread.

B. Considering the middle 50% of the training time;

Adam - 103 105 104 106 100

Miguel - 88 86 89 93 105

Adam's 50% range = 106 - 100

                               = 6

Miguel's 50% range = 105 - 86

                                 = 19

Considering the middle 50% of the training time, the person with the least spread is Adam.

C. The answers to parts 2(a) and 2(b) shows that; there is a wide variation (much inconsistency) in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.

Liono4ka [1.6K]

Answer:

7/11

Step-by-step explanation:

- 11 =  \frac{ - 7}{y}

=  >  - 11y =  - 7

=  > y =  \frac{ - 7}{ - 11}

=  > y =  \frac{7}{11} (ans)
