Answer:

\large\boxed{t>\dfrac{1}{2}\to t\in\left(\dfrac{1}{2},\ \infty\right)}

Step-by-step explanation:

9(t-2)>3(t-7)\qquad\text{use distributive property}\\\\(9)(t)+(9)(-2)>(3)(t)+(3)(-7)\\\\9t-18>3t-21\qquad\text{add 18 to both sides}\\\\9t>3t-3\qquad\text{subtract 3t from both sides}\\\\6t>3\qquad\text{divide both sides by 6}\\\\t>\dfrac{3}{6}\\\\t>\dfrac{1}{2}

3x+y=4 write the equation in slope intercept form​
LekaFEV [45]

Answer:

y = -3x + 4

Step-by-step explanation:

sorry im late

but all you have to do is isolate the y

so to do that we have to get rid of the 3x

3x + y = 4

in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y

3x + y = 4

-3x          -3x

y = -3x + 4

and now y is isolated

The data in the table represent the training times (in seconds) for Adam. Adam 103 105 104 106 100 98 92 91 97 101 Points Concep
Julli [10]

Answer:

A. Miguel has the greatest spread.

The range of the two persons can be determined by:

Adam's range = 106 -91 = 15

Miguel's range = 105 -86 = 19

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

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

Adam has the least spread

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

The answers to parts 2a and 2b show that there is a wide variation in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.
