Jazz is designing a rectangular workout space in their home. The perimeter of the room is 42 ft, and the width is 6 ft less than twice the length. Set up a system and solve to find the width of the room, in feet.

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

The distributive property allows you to say that 3(x − 1) = 3x −

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
