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.

The length of a rectangle is the sum of the width and one. The area direct angle 72 units. What’s the length, in units, of the r
insens350 [35]

Answer:

The length of the rectangle is of 9 units.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

Area of a rectangle:

A rectangle has width w and length l. The area is the multiplication of these measures, that is:

A = wl

The length of a rectangle is the sum of the width and one.

This means that l = w+1, or w = l - 1

The area direct angle 72 units. What’s the length, in units, of the rectangle

We want to find the length. So

wl = 72

(l-1)l = 72

l^2 - l - 72 = 0

Quadratic equation with a = 1, b = -1, c = -72. So

\bigtriangleup = (-1)^{2} - 4(1)(-72) = 289

l_{1} = \frac{-(-1) + \sqrt{289}}{2*(1)} = 9

l_{2} = \frac{-(-1) - \sqrt{289}}{2*(1)} = -8

Since the length is a positive measure, the length of the rectangle is of 9 units.

The answer is <span>A.9/16.

The ratio of areas of two similar squares is the square of the ratios of their similar side lengths. Since </span><span>the ratio of the smaller side length to the larger side length is 3/4, the ratio of areas of two similar squares is:
(3/4)</span>² = 3²/4² = 9/16.
